Boring Brick

[mrsam]

The wheels would screw onto the shaft tight as usual but then as soon as the robot was in the arena they would just spin on the shaft and not tighten up, not really sure why but it may be because the grub screws went early on and i didn't have spares. In terms of grip what had actually happened was that the tread had worn down so much that the screws holding it on were proud above the rubber hence no grip, but i only discovered this once i got it back for a proper strip down. As for the base material i'm still undecided, the 10mm Hdpe baseplate that was made at the event has held up brilliantly but i still think 10mm for a baseplate is too thick.

Edit: also just noticed your bit about the axe motor Matt, the current motor is more than powerful enough, if you think about it it's a 24v motor which i was running at 16.8v and it still had enough power to swing Hatchet's axe enough to break the chain on the axe several times. It definitely needs to be protected though and that is something that ill address in the next one, just some Hdpe bent around it with a heat gun would probably be adequate.
