Re: Going over 6 inch step with 12 inch wheels
Well when you think about it, when the front wheels pushing up, all your weight is on 4 wheels pushing up. When the back wheels are going up, you are pushing with 2 wheels. I know you probably can't do it, but a powered "climbing wheel" in the center that is set higher than the other 2 would help tremendously. When we were driving around our drive module without the articulating chassis on the front yet, we could still get up pretty well with 4 6" wheels in the corners and 2 wheelchair wheels in the middle linked to our main drive system.
