How can I create a Rolling Ball in SimMechanics?

Hello,

I want to create a rolling ball on a beam with Simmechanics Second Generation. But how can I realize a ball who is rolling on a ramp? I can only create a ball on a ramp using "Prismatic Joint". But then the ball does not roll, it slip!

Best regards, Ingo

I don't believe there is a way to truly represent rolling of a ball, but you may want to check out the rack and pinion constraint. It may be adequate for your application.
