Abstract: A robotic hand controls movement of a workpiece relative to three longitudinal axes in response to three control signals and relative to mutually perpendicular rotational axes .alpha. and .beta. in response to two control signals. Two C-shaped holders carry two motors having mutually perpendicular rotating shafts. Each holder includes two parallel flanges connected together by a web. The first motor is mounted on the first holder so its shaft extends between the first holder flanges. A second holder flange is mounted on the first motor shaft between the first holder flanges. The second motor is mounted on the second holder other flange. A carrier for the first holder responds to three of the signals which control movement of the first holder relative to the longitudinal axes.
