Abstract
This application describes multi-stage stop devices for robotic arms. During a first stage, rotational motion of a link of a robotic arm compresses a compressible member of the multi-stage stop device to absorb and dissipate at least some of the force generated by the collision. A second stage provides a hard stop the stops any further rotation. The multi-stage stop devices described herein can include a collapsing pin configured to compress a compressible member during the first stage. After the pin has collapsed a rigid sidewall provides a hard stop preventing further rotation during the second stage.
