I have a simscape model, in which a set of spheres are trying to grab a cylinder. I used the spatial contact force block between the cylinder and spheres. I set up two ways that the spheres move up: 1, Input a motion actuation to the prismatic model; 2, Input a force actuation to the prismatic model.
For setup 1: The tube does NOT move. The spheres slip along the cylinder.
For setup 2: The tube MOVE UP with the spheres.
All the other settings are the same except the input actuation. So I am wondering what is the reason for this? Can anyone help to answer? Thanks!I have a simscape model, in which a set of spheres are trying to grab a cylinder. I used the spatial contact force block between the cylinder and spheres.
