I am trying to make two rigs where the control is at the end of a linear actuator/piston. The piston can likely be done with a simple stretch to with a limit constraint to stop it at end position, but how do I tie this functionality to the other rotations?
I’ve tried several versions but am not getting close. Here’s the blend file with empty meshes (877.9 KB)
The first rig (left in image) has a piston connected to a quadrilateral linkage. It would be nice if the piston is fully extended before the linkage starts swinging, but that is a nice to have. My main aim is for the piston to extend and the linkage to swing using only one control.
The second rig (right in image) has the piston connected to a simple hinge that can rotate around its own (Z) axis. The control is yet again at the end of the piston. Here I need the hinge to track to the control somehow, while only allowing rotation around its own axis.
