A manually actuated robotic tool changer comprises master and tool units, each adapted to be connected to a different one of a robotic arm and a robotic tool. The tool changer includes a plurality of rolling members retained in one of the units and a piston mounted in one of the units and moveable in an axial direction. The piston includes a multi-faceted cam surface including an initial contact surface, a locking surface, and a failsafe surface interposed between the initial contact surface and the locking surface. When the piston is in a locked position in the tool changer, the cam surface is operative to contact the rolling members in one of the units and to urge each rolling member against a surface of the other unit to couple the master and tool units together.

A pipe spinning power drill accessory a stem, shaft, first knurled assembly, second knurled assembly, first state, and second state. The first knurled assembly and the second knurled assembly are each cylindrically shaped. The first knurled assembly is centrally affixed to the stem. The shaft is centrally affixed to the first knurled assembly opposite the stem. The second knurled assembly is centrally affixed to the shaft opposite the first knurled assembly. The first knurled assembly and the second knurled assembly each selectively expand laterally. In the first state, the first knurled assembly and the second knurled assembly are each not laterally expanded. In the second state, at least one of the first knurled assembly and the second knurled assembly are laterally expanded. The stem is configured to be inserted into a chuck of a power drill. The stem is cross-sectionally hexagonally shaped and includes a region of decreased diameter.
