Various aspects of robotic grippers are disclosed herein. In one aspect, a robotic gripper may include three gripper fingers arranged on a mechanical end effector, the three gripper fingers configured to translate radially when actuated to contact and align with a gripper interface located on a part to enable manipulation of the part. In various embodiments, each gripper finger may include an elongated portion configured to contact an outer surface of the gripper interface when the gripper fingers are actuated. Each gripper finger may further include a hook portion configured to contact an inner surface of the gripper interface opposing the outer surface. In various embodiments, the hook portion may include a receptacle positioned to align with a complementary protrusion on the gripper interface.

The present disclosure provides a grip manipulator used in a robot to eliminate an inefficient and power consumable operation caused by the use of multiple manipulators when gripping an object or handling the gripped object. The grip manipulator includes a manipulator body, a support rod of a first group and a support rod of a second group provided to protrude from the manipulator body in a direction, a longitudinal drive unit configured to discharge or introduce the support rod of the first group or the support rod of the second group in the protruding direction, and a transverse drive unit configured to spread or gather the support rod of the first support group or the support rod of the second group in a direction perpendicular to the protruding direction.
