Here we have some black UHMW pieces I got from McMaster. I cut them into 7in pieces and attached them to the base plate with #4 wood screws.
Strips of aluminum were then attached to the sides to protect the wheels. The feel a little flimsy though. I may add a middle piece of UHMW to reinforce the side armor.
Besides that, the rest feels pretty solid! The top armor will probably end up being garolite unless I have a lot of extra weight (which doesn’t seem to happen with my bot history…)
