Abstract: An apparatus for gripping fragile or irregularly shaped objects is provided. The apparatus includes a passive gripper assembly including an actuator for providing load to the passive gripper assembly. The passive gripper assembly further includes fingers to transmit the load to the object. Each finger includes a mechanical linkage to direct the load to the object, having a first end connected to the actuator and a second, free end. Each finger further includes a contact assembly disposed at the free end of the mechanical linkage that acts as a gripping interface. At least one of the contact assemblies is passive including deflectable elements configured to deflect upon contacting the object to distribute a gross clamping pressure. The load causes the fingers of the passive gripper assembly to close around the object such that the contact assemblies contact and apply the gross clamping pressure to the object.
