Oh you'd love to see my teams prototype but I don't have the pictures. To prototype the needed dimension to 8 wheels step climber, 6 powered, one of the other mentor used a half scale wooden one-dimensional model that had an adjustable wheel base and height. He used it on a half-scale step to plot how much each wheel has to pull the robot up. We determine the easiest path was the curve that was the flatest and smoothest (ramp-like). It was fun to watch, hopeful a full multi-dimension model will perform as well.
