Details in this pic.I want that extruded portion should rotate the cylinder when it makes contact with it and then carry it in the later motion.Capture.JPG

My first guess is to use a slot connection. You will need to model a curve in one part and a point on the other.With a slot connection the point will slide along the curve. You can specify (I think) a coefficient of restitution at the end points of the curve, so that there is some dampening when the point hits the end of the curve. I haven't played around with slot curves in a while, so I'm not sure how this works today.

Shouldn't be one body fixed for slot connection? Here both of them are given pin connection as each of them rotates.

I find it easier to simply mimic the motion with servo motors using specific timelines.

in this case, use a rack and pinion gear connection to a phantom servo motor and then a separate servo motor for the rotary motion.

Not elegant, but certainly achievable.
