If there are no other wheels beside the tri-wheel, what causes it to rotate and climb the step? It seems like the rest of your robot would, instead, rotate around the tri-wheel, tipping down.

when not climbing the stairs the chasis moves so that we can pick up the 2x balls. The forklift is not pictured. When the chasis moves all the way down and makes contact with the floor this causes the entire tri-wheel to rotate and allows us to climb stairs. "theoretically".... understand?

also, the little wheels are controlled independently of the tri wooden mechanism
