content: so... so.. many technical defaults and horrible piloting.... the axe swinging was determined to attack with the flat edge of the axe rather than the pointy one,hmm, 13KG weight limit for an autonomous killing machine, i think this forum could make something horrifyingly efficient for one of these comps. just if it happens i hope they bloody test it before throwing it to the wolves....

content: I agree that a large number appear to follow similar designs, however i think some of those flipper designs could be improved, still to that end a large number of those units are made to operate on both sides, not leaving a clear side to be flipped onto, so perhaps a whirling buzz saw will still remain the champ just on the fact your flipper arm means nothing when it get cut off,now a sell righting buzz saw, i see that as being on the right path,

content: I have always wanted to see a robot with some form of hydraulic vice grip/pressure rod combination. It would probably be hugely impractical, regardless of weight class, not to mention having a hard time catching its opponent.Yet if it did get a firm grip... Hydraulic piston pumps starting up, and the 20mm solid steel ram rod slo-o-o-owly pushing out from the front, toward the opponent. Initially our hero will get dragged all over the arena, as the victim attempts to break free. Yet soon the ram makes contact, and with tons of pressure on tap start to push through. Creaking. Pops. Groans. Sparks. Shrieks. Smoke. Deformation. Eventual silence.

content: ElectroIrradiator you could do it with only the claw, using a solenoid clutch, electric motor operates a downward direction claw, then once caught the clutch clamps and a hydraulic piston starts adding to the fun,probably have 2 flipper arms either side of the claw to both act as support and to try and flip when the claw will not work,

content: Every year my school had "Engineering Week" where there would be various competitions throughout the week for the engineering clubs to see which one was the best. At the end of the week they had a battle bot competition where each club built a robot and had them fight to the death. This is from one of our battles this year (it gets more interesting at around 3:40 (my club is IEEE)

content: I just never got the attraction of these competitions myself, "robot" to me means there should be large amounts of autonomy or programming at least, all these types of competitions I've seen it's just RC cars with weapons.Not that there is anything wrong with RC cars with weapons, if that's what floats your boat, I'm sure it's lots of fun, but I think calling them bots, is... stretching the definition considerably.

content: Quote from: sleemanj on August 05, 2013, 12:21:08 pmYes, good point, I was thinking the same thing. A fully autonomous contest would be very interesting. There could even be rules to make it easier and more standardied to track bots, like for example every bot had to have full circle coverage IR transmitters as a minimum.

content: the rules on that page are kinda iffy and unspecific.what about just using a robot with a mortar mounted to the front of it? since "excessive arena damage" is vaguely unspecific and it's neither explicitly an explosive nor a gun. sort of their weird cousinand as gun is not defined, one could make the case that it implies firearms or other chemically propelled projectiles and not lorentz field accelerated projectiles unless gun is defined as projectile launchers of any kindit also doesn't say you can't disable the driver somehow, using a gaseous anesthetic or excessive sound pressure, etc.and yes, the fun with rules is trying to find loopholesa projected water disruptor would be neat too, or several even.

content: Jamie says there was no countermeasure to Blendo. That may have been true when he was competing but one eventually evolved.Ziggo was a spinning robot inspired by Blendo. He was a two-time champion and was dominating his weight class when he came up against Code: Black. Code: Black was a robot buildspecificallyto defeat Ziggo.So did he? See for yourself.
