Now if you think AI design is easy, why don't you go program one?

Heh. I think for something with a high-tech golf cart motor spinning sharpened tool steel anvils, it would be very easy; here's a simple flowchart which could be implemented in the language of your choice:

1. Turn on rotating anvil motor.
2. Seek out anything which moves.
3. Chase anything which moves.
4. If anything still moves, goto #2.
5. Shut off rotating anvil motor.

Just make sure you don't accidentally turn it on when you've got it in the workshop. Or, worse still, when you're enjoying your new-found celebrity by showing it off in a booth at the local shopping mall. Granny probably couldn't out-run it, even with her walker.

You can get more power out of nicad batteries. They have lower internal resistance than lead-acid batteries. When I was in the military, I saw them used for high current applications like starting helicopter jet turbines and rotating turrets on armored vehicles.

WEll the Hawker genesis batteries are quite popular here in the UK for robotwars (we use panasonics but thats becasue we get them free), they are rated at 17Ah and so could supply 300A for 3 minutes (possibly a little longer). Also the motor is unlikely to be drawing 300A continuously. I would imagine once the weapon is spun up, unless it is very unbalanced (not likely looking at the quality of machining on the thing) then the current requirements would be much less.

You don't think this is just the same idea?

Personally these types of bots should be in a separate class -- there's no real point to trying to battle something with an impenetrable defense shield whirring around it waiting to hit anything with 10kf/p of torque. I'd classify this bot as purely defense. It can run around and defend. There's no real offensive tactic involved (spin up the rotor and attack? Please...)

I agree with some of the other posters -- the UK television show where the robots had to have good offense, defense and manouvre abilities was best. This show is simply "make it last and try to hurt the other guy" -- bo-ring.

The goal is to fight against ALL the types of robots... The finals this year were actually really close...

Yes, but that's not my complaint. My complaint is that if you build a bot capable of EMP it will always win, barring its own mechanical/electrical failure. You're no longer battling in the sense of "true" battle -- it's an unfair advantage. In fact, I believe that EMP armed bots are already disallowed.

(I also feel that the wedge-only bots are really lame. No offensive capability by anyones definition, no fight, no fun....)

I agree. This is the basis for my disapproval for the super-offensive bots: You pit bots of close calibre together for a real fight. It's no fun watching some $8000 superBattleBot go against a$400 robot built by a parent for his kids so they can get on the show.

My point exactly. And this is exactly what this battlebot is: A super-engineered robot killer. It should only be pitted against other super-engineered robot killers!

They aready have weight classes; why not damage classes within the weight classes, and then the winners from the various damage classes battle each other regardless of weight? I think that would be far more fair and (at least to me) far more entertaining. Yes it'd be more difficult to classify but then again that is why you have your weight classes and experience levels win martial arts (at least I believe this is so) -- the lighter, more experienced guy is still capable of trashing the heavy, inexperienced martial artist.

Uh, so you're entering a competition called BattleBots with a robot designed for what? House cleaning?

Sorry, but this is just whining that you can't engineer or spend as much money as someone else. BattleBots isn't the place for you then, go to a lower weight class or another competition or learn how to engineer.

There are defenses against any offense - flip a spinner and they're toast. You could design a bot specifically for use against Wyachi (and son, etc) by having a long flipper arm with one hell of a powerful motor/piston behind it and flip him before he can hit you. Game over - there's no righting mechanism. You can design a flip-proof bot, or one that has a quick self-righting mechanism, but then you may be vulnerable to spinners. Choose your poison.

The fact is, BattleBots is a pretty serious competition now. Win a title, get $6400. And then everytime they air a show with your bot, get a check in the mail for an additional$1600.

As for splitting the competition up even more - hell, there were over 500 bots there this year. Comedy Central showed a very small percentage of all the matches (too lazy to do the math right now). I'm rather annoyed about that, since they didn't even show all the regular matches, much less the prelims.

There's loads of things that could withstand the abuse of a 10kf/p impact at least once. Biohazard lost because it wasn't built heavily enough and it sheared off the armor skirts at the hinge points.

The impact stops the hammer wheel long enough to buy you purchase to attack the inner part of the bot with a vengeance. There's some design ideas my friend and I ran through while discussing the final match in detail this weekend. Right now, we're in the design/shopping for a sponsor stage (There's no way we could afford the gear we'd need for this beast we came up with... :-)

Anyone who saw the finals knows what I'm talking about here. The refs called a knockout against Biohazard while both bots were still moving. They decided to send it to the judges from there. This would have been fine, except at the time, one of the braces which keeps the pounding mechanisms at constant distances from one another had come off at one end, so the bot was just spinning beneath it's stationary weapons frame. The odds that Biohazard would have been able to overturn it seem fairly likely. I don't know about anyone else, but I would still like to see a rematch, though I realize this is now impossible.
