I have modeled a cam/follower mechanism for our FIRST robotics assembly and am trying to add a spring in mechanism to return the follower after the cam has rotated. I have tried both a linear and torsion spring and I can not get either one to work. Any advice will be apprecaited. Using Creo 2.
Picutre with cam still in contact:
Photo with cam past contact (springs do nothing). In this picture both the linear and torsion spring are active, although i would only use one in the real design.
