Abstract
A semi-active compliance device forms part of a robot used to stack packages. The semi-active compliance device has an X-Y motion mechanism and a remote center compliance mechanism. The X-Y motion mechanism provides active open-loop control of the forces of a package along the X and Y axes so that the X- and Y-axis positions of the package will be passively controlled by the environment (e.g., walls and/or adjacent stacks of packages). The X-Y motion mechanism has two linear actuators and two pantographs. The remote center compliance mechanism provides passive orientation of the package about the Z axis. The semi-active compliance device also has a mechanism to return the remote center compliance mechanism to a home position.
