I say why not use REAL weapons: guns, flamethrowers, EMP devices, etc. That would pique my interest. Have the announcers discuss why a particular bot has to have a Faraday cage around it when the other robot does something. Also, it would bring testing to a whole new level. Fireproofed, shock proofed, etc.

Just my $.02

    You would want to shield the arena then otherwise you'd have a very pissed off crowd when they realised their mobiles had suddenly died... Cartridge based weapons would be too dangerous to the crowd, flamers would be interesting... From a viewers perspective EMP is pretty boring, you don't see anything, jsut suddenly half the bots that forgot to add shielding stop working.

    Well, naturally arming these so-called "robots" with real weapons (guns, knives, etc) could pose a threat to the public and a liability to the producers. In addition, I'm not sure where battlebots is filmed, but they would have to make sure that they comply with local gun laws, in some states (like California) that could be tricky, and the consequences for non-compliance are severe.

    As others have said, those weapons are illegal under the current rules, entirely for safety reasons.

    Now, how about "Extreme Battlebots": The arena is open, dozens of remote cameras are the only spectators for a thousand feet around. Use whatever weapon systems you want, up to and including explosives (within a reasonable limit, of course).

    You'd have to go off-shore, more than likely, due to the explsoives, but otherwise it could work. Now, would anyone want to compete? And, how do you deal with the 'bot that is nothing but a satchel charge with wheels?

    Still, it'd be fun to watch.

    BATF agents are not known for their sense of humor. There is a licensing category for "destructive devices", but it would be a lot of trouble and expense. Plus, California has some of the worst weapons laws in the country. One way around California's stupid laws might be to become a movie producer. There are exemptions written into the laws for Hollywood.

      Unfortunately, the Battlebot rules say no water. In fact, here's everything they say.

      11.2 Forbidden Weapons
      The following weapons may not be used:
      Electricity - The use of electricity as a weapon shall be forbidden. This includes, but is not limited to the following:
      Stun Guns/Cattle Prods
      RF jamming equipment, etc.
      EMP

      Liquids - The use of any liquid as a weapon shall be forbidden. This includes, but is not limited to the following:
      Water and other liquids
      Liquefied gasses
      Chemicals or corrosives
      Foams, Adhesives, etc.

      Visual Obstruction - Any attempt to impair the vision of another Contestant shall be forbidden. This includes, but is not limited to the following:
      Visible smoke
      Lights/lasers directed at the Contestants, etc.

      A BattleBot that smothers/covers another BattleBot is permitted.

      Projectiles - Untethered projectiles are forbidden. Tethered projectiles are allowed. Tethered projectiles can carry a tremendous amount of energy, the restraints must be strong enough to absorb this energy without sustaining any damage. The length of the tether as measured from the body of the BattleBot to the tip of the projectile must be less than 10 feet. Contestant may be disqualified for intentionally using a tether as an entanglement device (see #8).

      Heat/Cold - Heat or cold specifically generated to damage an opponent is forbidden.
      Flame Throwers
      Plasma Torches, etc.
      Liquid Nitrogen

      Entanglement Devices - Any device specifically designed to entangle another BattleBot shall be forbidden. This includes, but is not limited to the following:
      Any type of net.
      Fishing Line, String, etc.
      Tape

      A grappling hook type weapon is not considered an entanglement device.

    Because some of the poor beasties can barely wobble into the arena under their own power as it is, let alone if a Cyberdyne T-200 is EMP'ing the area. Explaining the importance of shielding your systems might be instructive, but it's hardly entertaining - except maybe to us, and we're hardly a mainstream audience. ;)

    I was thinking either a Taser Gun where the BOT shoots out a line and jolts the enemy's circuitry.

    Or have an electric welders contacts mounted on several sides at the ends of some reinforced spikes. A high powered motor to charge, penetrate and zap the opponents.

    And to combat the flippers .... the wheels are mounted to extendable lifters that can rise and then drop when the flipper gets underneath... However when the frmae drops back down the spike mounted to the underneath of the car damage the flipper.

    Cool thought -- not sure if they can work.

    The new season (which just started airing) is a little better. First off, the hazards are much more dangerous, and can actually do damage. (The hammer, which was rather useless previously, seriously crushed one bot that was on its way to victory.) Secondly, there were many more contestants this year, so not only is there a better crop of bots, but the producers can afford to be selective and not show the really boring and pointless matches.

    It's an upward cycle, really. The more people that see it, the more people that participate and the better the competition.

Battlebots is completely lame because the robots are human controlled. And because they are human controlled, they are cannot, by definition, be called robots.

Just because the device the human is using to control the "robot" is a computer and the "robot" has a computer onboard does not make it a robot.

With the cheap processing power available today and the current state of AI there is no excuse, bar incompetence, for this competition to not consist of truly autonomous robots. Until then, Battlebots will continue to be a show pandering to the lowest common denominator, relying on sex and loud music to attract an audience.

    They allow autonomous bots, just none of the autonomous robots choose to compete against the human controlled robots. It's my understanding that there are certain exhibitions fights (such as Mark Setrakian's Mechadon, Snake, etc.) for robots that fall outside the rules but are still entertaining for the audience, so autonomous bots tend to fight there, but I believe they're few and far between.
    I'm into autonomous robots myself, and am considering getting into BattleBots, but at least with some fly-by-wire intelligence on board, perhaps with some sensors as well.
    I think your assertion about 'the current state of AI' is a little misguided. When was the last time you sat down with a compiler and tried to write something to make a robot do anything, much less be intelligent, or engage targets with deadly force at its own discretion? Don't you think there's a reason the military still mostly has 'dumb' weaponry..aside from being guided by GPS and recognizing its target optically in a highly preprogrammed manner, it's still dumb.
    Another thing is..the more intelligent a robot is, the less likely you are to want to see it destroyed. What would it say about humans if we took intelligent, thinking beings and threw them in a pit to fight to the death just because they were machines? I think it's better left as an extension of the phallus (not that Battlebots isn't fun :).

    When I was doing engineering at University we had to build responsive systems using Lego Dacta (educational tool kits, Mindstorms was born from this). Our group build a roving unit that would sense and object in front of it, if is was blue or yellow lego bricks it would attack it (swing an arm and knock it down) otherwise it would try to find a path around it.

    Now that was 7 years ago, I think we could develop a lot more fun robotics and programming now.

    Special case "AI" sucks though.

    Instead, maybe what someone needs to do is, create a new bot named Eurisko^2; give it a baby neural net and a basic genetic algorithm to follow; add-on the requisite computer vision and extra-sensory feedback; feed it its capabilities and the battlebot ruleset, and then...set the thing loose in a parking lot full of angry kiddies wielding spiked baseball bats, hammers, flails, power-saws, fireplace pokers, and wedge-shaped shovels (oh my!). Let it evolve in training, tuning its neural pathways with do's and dont's, like any good pavlov dog would.

    Of course, anything learning in meatspace is slow, so you'd actually want to simulate those trillions of battlebot matches on that 'beowulf cluster of toasters' in the basement; breeding the best bot with the best strategy to fare against the most varied set of other possible enemy bots.

    If you read the article, you'll find out exactly why there are no autonomous contenders - because they'd have to be completed by hackers.

    • PVC was chosen primarily because we are computer people, not mechanical people [...] we hit a column with a rubber mallet. The joint shattered (the hard plastic) and hit every wall in the garage!
    • the bot was retired before the armor was built [...] it never saw a fight
    • if certain relays were closed at the same time the system could short itself out, so care had to be taken when issuing commands to not do that!
    • This is what happens when you hook the batteries up backwards. A big bang, lots of smoke, and a blown cap.
    • This is what happens when you don't use fuses. Something starts to smoke... Fortunately, it was repairable and nothing expensive broke!
    • Everything on the bot is complete and works, except it draws too much power

    Note to the easily angered, I'm not dissing these guys, this is a fun project, and well documented. But it kind of typifies the hacker culture of build one to throw one away - then get bored and go on to something else. Hell, I've got a hand built car sitting in my garage that I never drive. Like these guys, I built it to learn how to do it, not to actually drive it around or anything. ;)

    I'm wondering if you've ever tried to build a self-motivated robot.

    While I completely agree that AI would be a nicer way to have bots fight, its damn near impossible with the current state of sensor-ware. It's far too imperfect and slow.

    Oh actually unless you're talking about the kind of sensor-ware that ends up in high-grade military weapons. Then it probably wouldn't be battlebots anymore. It would be an entirely different monster.

    I do however think you could have AI augmented bots, that do things like attempt to auto-aim the on board weaponry after the human controller has gotten them close. Or some kind of in-bred overriding defense response.

When the publicity shots for BattleBots.com come up there is a much better picture. Here is more info: Team TuxBot builds BattleBots for fun and not profit. All profits from competition will be donated to the EFF and FSF. Unfortunately we didnt advance far enough to win money this time. (Cant say how far due to an NDA) All of our programmers are allready Free Software developers whom work for Brainfood.com. Our sponsors are/were Linux Journal, Tri-M Engineering, and Brainfood.com. As for build reports I've got them and they need to go up. Suffice to say we were too busy making the bot ready to actually compete to keep as good of records as we should of. (We were working till 4am on this thing then getting up around 8am for work.) If you really want build reports I'll post what little we have. Currently we're busy rebuilding Violator and our new bots. If you are looking for *real* build reports then join the BattleBots forum on Delphi. Team TuxBot is open to anyone whom builds a Linux powered BattleBot and agrees to donate any profits to the Free Software Foundation and or EFF. (Or pretty much any other advocacy group) Even if they dont join I'd really like to see the other Linux teams agree to the donation principle. If they dont then I dont think they are doing this for the right reasons. (AKA the "Right thing to do") Cheers, Eric Molitor www.brainfood.com

    What would really be great would be if it actually won a match.
    Although actually, knowing how junkyards come into play, there IS a decent weapon available - the phallic sonic ramrod. Take any working, but junked vibrator (just be sure to wear gloves...), overclock it (double the voltage, stick a Peltier in there, etc. etc.) attach a sharpened roof nail to the end, and voila - a ramrod that vibrates the opposition apart while offering a superb visual effect for prime-time TV.

    Quoth the article: Most battlebots are just glorified RC cars. They use off-the-shelf speed controllers, and stock RC controllers. Unfortunately, this makes them impossible to drive.

    It's not the use of R/C car parts that is the problem. A good R/C car is a dream to drive, very controllable. The problem seems to be with the operator's choice of controllers. I keep seeing these sort of twin-stick controllers in use for simple wedge bots with no extra weapons; why the hell don't the operators use pistol-grip style controllers?

    I could never really get the hang of twin sticks, but I can pilot a car pretty well with a pistol grip. AFAIK all serious R/C car guys use them, and for good reason.

    The Battlebots arena is PLAGUED with really awful driving. I'm sure a heavy bot isn't as easy to drive as an R/C race car, but c'mon, most of these guys could do a lot better, and I think better controls would help. (I saw one guy using a freaking joystick... I think he got his clock cleaned, too. Use the right tool for the job, Chester!) The videos they show of the designers tearing up junk in parking lots... not a great way to practice. A parking lot is a lot bigger than the arena, and poor control won't be punished as much. Especially when you are wrecking a TV or an aquarium, instead of another bot.

    I know some bots need more than just movement controls, and a 2-channel pistol grip isn't adequate. Nonetheless, it sure looks like some teams are sabotaging themselves with a poor choice for mobility controls. Mobility is life; precise driving should be the first requirement for any bot.

    Seems to me a team should have one driver and one gunner (yep, some do, I know), or perhaps one operator using some innovative controls like footswitches to operate the weapons. A pistol grip with 2 foot switches for the bot's gadgets -- that would be the way to go!

      First, glorified RC cars are not a bad thing. I wish my REGULAR car was as ludicrous as my Nitro RC, and I have a shiny new sports car as it is. 1.2 bhp on the dyno for something that weighs about 1.15 kg. Talk about power to weight ratios! Plus a full PCS system including a working 3rd channel for making needle valve adjustments on the fly, tunable modulated hard braking (ABS), etc. This car has nearly as many tuning options as a real race car. With proper gearing and a 2-speed transmission this thing can get to 60 as quickly as most sports cars. Top speed is about 70 (gear-limited).

      I think people on battlebots are just too cheap sometimes to drop in a $250 all digital 3-channel control system. In my opinion, its damn worth it.

        As the other poster said, most of these run like tanks. It would be rough to get good control out of a tank like car using a pistol style control. Allthought, it would be interesting to see how they control a tank style system using the two sticks as forward/reverse for each side, considering the left stick is usually a throtle that doesn't snap back to the middle like the stick on the right. Maybe there's a way to modify the radio to fix that problem, I've never looked into that... If you read the build your own battle bot thing, the author recomends a 6 chan heli radio. That's still twice as many chans as your high end 3 chan pistol system. You need that kind of control for turning on saws and droping blades, and whatever else it is your bot does.

        Besides, using a stick system isn't that hard, I do cars and airplanes right now, maybe helis soon. You get used to the controls for both. I'm precise with either a car or a well built plane. Allthough since I don't normally do cars, I'm much better with a stick type radio I use with my planes. It's just a matter of practice.

        Three channels typically isn't enough for a serious battlebot.

        For a car, two channels is the norm and you can get a third channel for more money -- but that's it. For more channels, you'll have to get plane equipment or spend a *lot* of money on specialised hardware.

        `All digital' isn't required (I assume you mean PCM?) FM or even AM ought to be fine (but BattleBots prohibits AM, so it's moot) -- after all, modern R/C equipment has an effective range of around 1.5 miles -- far further than you can even *see* your plane. For a bot, it's unlikely to ever go more than 100 yards from you. At that range, interference isn't much of a problem, even for AM, unless somebody is on your exact frequency.

        One thing to note that they don't seem to tell you -- in the US, airplane radios use the 72mhz band, which the FCC has designated for aircraft only. To use it for a ground craft is *illegal*. For ground craft, you're supposed to use the 75mhz band. (There's also the 27mhz band, but few people use it because it's also used by CB radios and there's only 6 channels there anyways. And there's also the 50 and 53mhz bands, but you need to have a ham radio license to use these.)

        Futaba will convert some of their higher end radios from the 72mhz band to 75mhz band for $40.

        If you do actually make your own robot, please don't use 72mhz equipment! There may be a flying field a half mile away that you don't know about, and you could crash somebody's plane without even knowing it.

        (I emailed the coolrobots.com guy about this, and his email bounced -- mailbox full. Guess it got /.ed ...)

          Range and interference ARE a problem, even with PCM radio. You've got lights, arena hazards, camera equipment and the like all giving off radio waves. This is something that R/C airplane people don't have to deal with. And I know this for a fact. I competed at BattleBots Treasure Island and had interference problems.

            A PCM radio is just as vulerable to interference as a FM radio -- in fact, it sends it's signal the exact same way that a FM radio does. The signal itself is different, however -- it has servo signals, checksums and failsafe information.

            If the signal is lost for a fraction of a second, servos stay in the location of their last known `good' signal. If the signal is lost for longer, they go to the `failsafe' setting, which probably turns off all the motors if the bot is configured properly.

            With FM, interference usually just causes your servos to stop moving and stay where they were -- but sometimes the right interference can cause `glitches' -- which could be dangerous. Normally they don't occur under normal conditions, but from what you said, a BattleBots tournament isn't a normal condition.

            PCM radios have higher latency than FM radios -- your imputs translate to servo movement more slowly -- but it's a pretty small difference and most people don't even notice.

            That all being said, having a 300 lb robot with a chainsaw in front, having a PCM radio (with it's failsafe settings correctly set) is probably a good precaution, especially if the interference is as bad as you say it is.

            So, what frequency band was your radio equipment on? :) What did most people use? (do you know?)

        Actually, this wouldn't help much at all. You'd have a narrow little view of the action.

        Much better to practice with your bot and learn how to use the 3rd person perspective to your advantage.

        People have tried putting cameras on R/C planes and cars with various degress of success -- but it rarely works as well as an experienced pilot/driver with a good view of the craft.

      why the hell don't the operators use pistol-grip style controllers?
      Many battlebots drive like tanks. With no steering servo, these pistol-grip controllers won't work well, unless you do some sort of mixing (where the steering control adjusts the speed of the two wheels/tracks.) Could be done, but adds complexity, making things less reliable.

      Also, you'll be very hard pressed to find a pistol grip controller with more than 3 channels. Of course, if you have a seperate driver and gunner, giving the driver a pistol grip controller and the gunner a standard two stick airplane controller (on two different channels, of course) would probably work great.

      Also, the two stick controllers aren't bad for R/C cars at all. I've got both, and while I do prefer the pistol grip, it's not that big of a deal. But then again, maybe I'm biased because I mostly fly R/C planes rather than drive R/C cars.

      There are a few builders who use RC Car style controllers, typically to good effect. The best controllers for Battlebots tend to be custom ones - They are becoming increasingly common(Including Battlebots that use computer joysticks for control :) The main reason for the Aircraft style radios being so common is all the extra features - I can't think of an wheel-style radios that have the programmability of a Futaba 8-series aircraft radio, nor that have so many channels (Several robots actually use all the channels on the 8 and 9 series radios).

      IMHO, as a bot builder myself (I competed in the May competition), the main enemy for bad driving is lack of practice. I ran so close on construction time that I only had about 10 minutes to practice driving before the competition; After that, I had to box it up to ship it. Some people drive for the first time in the box :) Another problem is spatial orientation - It's sometimes hard to aim weapons when you're not looking from directly behind the bot. Someone at the most recent competition tried putting a VR camera in the nose of a bot to drive that way. They recorded the feed from it; There might be some exciting shots of the camera charging at and coming very close to a spike :)

      p.s. To those of you who are talking about "Why isn't it autonomous" - There used to be an autonomous element in the competition. It fizzled out after a couple years because no one could program an AI good enough to do any damage. Actually, most of the autonomous matches involved the bots bumping into the corners for 3 minutes trying to find each other :). If you think about the complecxities - Image recognition; Trying to navigate in relation to the edge of the box and the hazards AND the opponant who is trying to outmanuver you; What happens when it sustains damage to a critical sensor; computers being fragile enough that the average battlebot fight would absolutely demolish one; and the very writing of the code to process it all; It just seems to be a bit much, and it has proven to be so in the past. Look at humans driving - we have the best computer in the world in our head, and most of us can't do it very well :). It's a cool idea, but it seems the time hasn't come for it... yet.

      Those wedge bots use a trac type drive system.. left stick controls the left trac/wheel and right stick controls right trac/wheel. If you ever drive a dixon lawnmower or a bulldozer it all comes natural. Both sticks forward for going forward, both sticks back for going backwards. 360 left with right stick forward and left back, 360 right with left forward and right back. simple right turns with left stick forward and right stick slowed or off (or yanked back momentarily for braking).

      The pistol grips dont provide the right control for trac/separate side driven vehicles. Pistol grips are ok for stuff that drives like a car.

      Joystick controls would be ok to control either design, car or trac. For a car style with joystick design forward/rev would control for/aft movement motors and left/right would control steering. For trac style forward would activiate both tracs to go forward... back would activate both tracs to go back. and left would possibly do 360 unless you programmed the 360 movements with buttons, and had left just kick the right trac forward. ditto right. But with a trac/joystick, there could be confusion of the zones where it would stop going forward and start trying to turn. (need some programming)

      If i had an unlimited supply of $ i wouldnt mind putting my traxxas nitro powered rc truck in the ring after buying all the metal replacement parts and adding a modified roll cage and add some kind of anti roll mech. My traxxas tends to roll pretty often as a cause of braking too fast or trying to turn at full speed (gotta remember star trek rules.. warp speed in straight lines, and turn on impulse speeds). I would also want to fix my reverse gear so i can repeatily ram someone (my reverse sometimes gets stuck or becomes nutral). I know this thing has a lot of weight and can pretty well ram anything. Add short peircing spike to the front and back, and start her up!

      I have taken my traxxas indoors onto concrete gym floors, confusing donuts are very easy :P power slides, and brake slides on smooth concrete require skill. (I love doing that stuff while ppl are standing around gawking.. just power slide right in front of them, then come back and brake slide to a stop at their feet and blow full throttle in reverse to left or right for some awesome donuts!) Im sure playing around in one of those robot war places would be simular surface.

The punchline was that a lot of the harddrives locked up and crashed the robots.

        Yes, but flash is expensive and (electrically) fragile. It's also hellishly slow to access, but that's probably not an issue here. It's light and low powered (when reading), but again, that's not an issue in a typical battle bot.

          Flashcards may be more electricaly fragile. But they are more mechanicly stronger than a HD, since they have no moving parts.

          Don't forget these are battle bots. It gets a little more intense than just "opps... I dropped my laptop." (and one could even consider that intense).

          Also, if you talking about CF cards (I think they can be used just like an IDE drive, with an adapter). You can get them quite cheaply now, especialy for a 8-16MB card. That's plenty of room. Unless you install win98 on it. But since you can get linux on a iPaq. I shouldn't be too hard to get a striped down version of linux on to a CF card.

Like the 4th paragraph on the page: "What about armor? Though the bot was retired before the armor was built, here is the idea: The armor is mounted on springs which are attached to the frame. The strength of the springs is just barely enough to keep the armor off the ground (around 2"). When an attack comes from the top, the springs compress which drives the entire shell to the floor. Once the armor is on the floor (which is before the springs completely contract) the force of the attack is transfered to the floor through the primary supports in the armor. Thus, the attackers force never actually contacts the weak PVC frame."

    As someone who has actually built a BattleBot and competed in the competition, I must say that the PVC "BattleBot" that was linked is an utter piece of manure. It would not last a quarter of a second with 99% of the bots in the competition. Its control system is not innovative, nor unique. In fact, there are robots that have much more involved and high-tech control processing systems that have either been custom built or bought. On-board linux computers and custom microcontrollers are not unique by any stretch of the imagination. Many of the builders are moving towards having much of the difficult and annoying tasks accomplished by the BattleBot itself, with the driver simply telling it where to go and when to do it. While none so far have been truly autonomous, there have been a couple of valiant attempts that did not quite pan out once in the BattleBox. If you watch the newest season of BattleBots that is currently running on Comedy Central, I think you will be surprised at the level of mechanical engineering involved as well as the software that is needed to make a large number of the BattleBots function. That hunk of PVC wouldn't survive a few seconds with any lightweight BattleBot, much less a decent one.

It is steered by the head actuator and uses the motor to drive. Here's another site with the same idea but more details: http://www.generation5.org/aisolutions/floppy.shtm l

    Back in the day about 4-5 years ago, before Comedy Central picked up on it, they had the Robot Wars competition in one large 4 or 6-hour event on the Discovery Channel. No sportscasters, stupid interviews, etc. It was thouroghly better than what they do today...and I think a bit of the rules about weapons and such were more relaxed. Pertaining to topic, what is the point in making a battlebot if it's not "yours"; i.e.: your design and manufacture. Just my 10/500ths of a dollar

      I think you'll find Robot Wars is still going, even after all the nonsense about who owned the name.

    Considering the amount of hardware that gets tested, swapped, broken and added to such an endeavor, I was wondering just how frustrating it would be to attempt such development on Windows XP ?

    Or better yet, I can see it now, during the day of the competition. The bot's about to get sliced-n-diced by the entry from Ginsu*matic while the operator of the XP bot is trying to get through the MS validation process on a cell phone.

    Then I thought about all the times I've been on the road for trade shows ... all the last minute hardware changes ... but I digress.

    Questioning the sprung armor design idea (Score:1)
    by elmer-12 on Sunday July 15, @08:55AM PST (#116)
    (User #117845 Info)
    From the article, "When an attack comes from the top, the springs compress which drives the entire shell to the floor. Once the armor is on the floor (which is before the springs completely contract) the force of the attack is transfered to the floor through the primary supports in the armor. Thus, the attackers force never actually contacts the weak PVC frame." - and the floor pushes back on the primary supports, causing them to buckle, yes? Am I missing something or does this part of the design really work?

    Battlebots sounds pretty weak compared to the stuff SRL does. Not having/watching a T.V., I am uncertain about the details of these shows, but to me it sounds like SRL takes both Battlebots and Scrapheap-mumble to a whole new level.

      I went to the Phoenix show (1996?), and recently (October 2001) helped Mark Pauline and David Therrien set up for a demo here in Phoenix (at X.E.R.O/ChemLab) to show off one of the pulsejets that was to be used on their new hovercraft (which was supposed to make an appearance at the Ultraviolence show in Phoenix - but it got cancelled thanks to a lovely interaction between the SF Fire Marshal and the Phoenix Fire Marshal - thanks a lot, guys! Bastards!), and also a video showing of various prior shows.

      The demo went off without a hitch - though every time I saw the pulsejet running - glowing white hot and screaming like a banshee on speed, being manipulated by Mark and company using asbetos gloves, next to the 50 gallon tank of propane that powered it - I wondered if we weren't all going to end up crispy critters.

      If you haven't seen an SRL show - you don't have any idea what you are missing - picture being in the middle of a war zone, along with a crash-up derby, and a lot of fire, heat, and smoke - plus a ton of noise that manages to rattle every tooth and bone in your body, while deafening you despite wearing ear protection, incidentally making your ears ring for hours after the show - and you might have some idea about what happens during one.

      I put in that time to help on the show - all volunteer, mind you - hoping to help out later for the real show - and then it doesn't happen! Gah!

      Anyhow - yeah - SRL makes Battlebots look weak, weak, weak - of course, SRL does beaucoup planning to keep accidents, etc from happening - while Battlebots is more "anachistic" in that fashion, in a way. I tend to think of Battlebots as a tamed down SRL real battle (whereas the destruction of SRL's machines, while real - doesn't tend to utterly destroy them, as sometimes happens with Battlebots), and a different form of entertainment (plus, without all the smoke, flames, heat, and falling ash - it is easier to see what is happening)...

    His site has the full design for a bot that runs on an onboard 486 and is controlled off a laptop with quake-style controls!

    It looks like they put in a computer, then used it to emulate a really dumb R/C controller. Why?

    Watching those things, it's clear what's wrong. People are driving them visually, which means too long a reaction time. They need some onboard smarts.

    The idea here is to get inside the other guy's OODA cycle , so he's reacting to what you were doing, not what you are doing.

    The first step is to get some onboard heading control. Put in some cheap rate gyros, then control orientation with a knob attached to an encoder. Want a 90 degree turn, spin the knob 90 degrees. That way, you'll get the desired heading on the first try.

    Second, some kind of system that senses the opponent at close range and maintains position relative to them so the weapons can work would be a big win. Ancient though they are, the old Polaroid sonars would probably work. Use the piezo ones, not the electret ones; they're more rugged. And use separate send and receive sensors, so there's no minimum range. The idea is to make the weapons stay on a target long enough to have an effect.

    Hello All,

    Just wanted to tell you all about something much more realistic then entering a bot in BattleBots (plus more flexible ;-)) Build your own Lego Bot! A few of us in Albany, New York have started a group called BattleBricks, where we build bots for various competitions once a month and try to destroy our fellow opponents. Quite fun!

    I've been building combat robots for a few years now, and competed at BattleBots Treasure Island 2001. I thought I'd offer some insight on this robot.

    PVC is a bit weak for BattleBots. I used it on my first robot, The Tunabomber, but that was for DragonCon's Robot Battles, where they don't have killsaws or robots like Whacker and Ziggo. Incidentally, my website has a tutorial similar to the one referenced in this story, but with more detail.

    An onboard PC is certainly overkill for control. I do give it points for hack value, though. Competitors who want computer control functions usually use the IFI system. This also allows you to use PC joysticks to control your robot remotely (a joystick setup was mentioned in an earlier post, this is almost certainly what was used).

    I wonder why the guys who built this robot didn't compete with it. After going through all that effort, it should be worth it to get to the competition, if only to see your robot ripped to shreds.

    Finally, please moderate down all those people who talk about how easy it is to build a winning robot, unless they've actually done it. Slashdotters: as with Open Source, it's put up or shut up.

    Last I checked, one of the highend super heavyweights used a Logitech iForce Joystick. I'm not sure HOW, but all I know is that's what he used. I know that at the heavy/super heavy levels, competetors use other similarly complex control devices as well. The glorified RC Cars are really on the light and some on the middle weights. Which when you're limited by weight, you don't have much anyway. maybe a saw blade, or something. I'm wondering why no one's taken advantage of a spike, the tethered weapon rule, and the firing technology of choice by hasbro. Spring loaded. It's off topic but think about it!

    Mauler, Battlebots (Score:2)

    As mentioned, Christian Carlberg has made some terrific robots (Minion, in particular, has won the Super Heavyweight title in the past).

    But, of the Battlebots, my favorite is Mauler. A spin-bot, Mauler rapidly spins and can do some serious damage to other robots. It's a shame, though, that Mauler has such low reliability -- in past fights, it always seemed to just sputter and die (mostly from encounters with the hazards). If Team Mauler could just make a more robust version, I think they could really go far in the event.

    On another note, I've had to do without cable tv (due to my current unemployment), including Comedy Central. So, I'm looking for someone that could tape BattleBots for me. Perhaps you could fill a VHS tape at SLP, and then I'd PayPal some money to cover the cost of the tape and expenses. Or, something like that -- e-mail me if you're interested.

    I would have thought that something like a Palm Vx(or any palm really) would have been better. Way smaller, lighter, takes less power, more reliable, and probably easier to progam for.

    It may not be as powerfull. But motion control for something like radio gear doesn't even require the power of a 286, let alone a 486 with a 340MB(!) Harddrive.
