I'm trying to make rocker bogie assembly to climb over the obstacle; however, I cannot make the rocker bogie wheels roll. I created cam contact and created servos at the wheels, but when I run the simulation, wheels just spin about their axis and don't go anywhere. Does anybody know how to make a wheel roll on any surface?
there has to be friction for rolling motion. otherwise they will only slide on the surface.
You can not roll the wheels on surface with pin type mechanism on wheels.
But you surely can slide the surface w.r.t. wheels rotations. Its a tricky job!
Best of luck.
