Great event. Great robots. Great commentary.

Understood

Are the bands to preload the claw and give it more downforce? Neat idea - I thought about doing the same with springs on mine but I still have to stop the disintegration of the drive gears first. Looks like it drives really well with something grabbed and the front off the ground too! There's a tri...

It will not get much better than this...

Just wondering what the crushing mechanism is going to be, is it a lead screw that's connected to the crushing jaw on a bearing? Looks really nice so far. The claw is mounted to a shaft that runs between the gap formed by the two metal plates. The shaft is supported by two bearings on either side.

It's looking very good... What method of crushing are you using? Curious because I've been using large servos, but they weigh an awful lot, are you using hydraulics of some sort or other? I'm using a Pololu Micro Metal Gear motor with an extra gearbox screwed on. I can't remember the model, but you...

I feel that you are pushing that motor to its limits. Even with all the gearing you are likely getting inefficiency and such throughout the gear and its about maxed out. For a crusher weapon you might want to consider a system that is specifically built for this application- a linear actuators such...

I wouldn't like to think that people who don't have the expertise to build a robot from scratch were completely ruled out of AWS. Maybe a more inclusive rule might be that you have to have made your own body and your own weapon (spikes included). I guess we have to set some standards for AWS, but we...

It seems that when you are measuring "force" here, you are really meaning torque, which must be defined by pressure AND distance from the centre of rotation. eg foot pounds, inch ounces, Kg cm, etc. Perhaps the force you are quoted are at 1cm? Then if the crusher point is 2cm from it's ce...

Im not sure what amps the Rx will output.

Mmm, that's an idea. I don't have a small enough scale, but my neighbours might!
