I need a 2DOF arm to move a part, where the perimeter of the part continuously contacts the pivot (red), but never moves in the restricted area. Imagine the pivot (red) is a spindle, and the part is machining around the edges.
The purpose is to visually observe the range limits and clearance of obstacles.
I've tried multiple joint types, even creating a machine in manufacturing "machine builder".
The closest I've got is using the "move/copy" command, manually rotating the part. Note: yes, the 2DOF arm is jointed with revolute joints.
Ideally the pivot (red) is jointed to the perimeter of the part.
As this is a concept, I don't have a file to share.
Simplified example: (The part moves along it's perimeter, rotates at the corners, while the perimeter is in contact with pivot (red))
