Abstract

A robotic end effector is disclosed. The end effector is configured to grasp, move, and place one or more objects without assistance from another robot. The end effector includes a lateral member configured to be coupled to a robotic arm, a passive side member coupled substantially rigidly to the lateral member at a first distal end and configured to engage mechanically with a first recess on a first side of an object to be grasped, and an active side member coupled to the lateral member at a second distal end opposite the first distal end and configured to engage mechanically with a second recess on a second side of the object to be grasped, the second side being opposite the first side of the object to be grasped. The passive side member and the active side member each include a structure, and the structure on the passive side member and the active side member have different profiles.
