Re: motorized robot carts
Yes its really safe. Theres a lip all the way around and I hold onto the robot while driving. Drives like butter on flat ground, like a snake on angled.

Re: motorized robot carts
Question regarding any carts in general. We had a less than stellar cart last year and we had trouble going over the bumps that covered the wires on the ground. How did you guys overcome that problem?

2. Bigger tires go over bumps easier, so having a relatively large wheel size helps. 3. To go along with 2, a tire with some give also makes the transition over a bump less severe, so pneumatic tires work extremely well for that. McMaster P/N# 22925T71 also comes in a rigid form factor that allows you to use the ideal steering setup of 2 casters and 2 fixed wheels. Hope it helps. -Brando |

Re: motorized robot carts
Probably a bad idea on non-flat terrain. And there's just enough non-flat terrain at a FIRST event to make this troublesome—cable raceways, floor protection panels, small ramps, etc.. I suppose it wouldn't be a huge deal if you can just push it to overcome those obstacles.

Re: motorized robot carts
I thought of that and our mec's have large enough rollers and a sufficent diameter for wires. We also will use a pnematic suspension on the rear two wheels to accomidate non flat surfaces. But in the end our 4 super cims should power through the bumps
