ABSTRACT:
A computer controlled exercising apparatus is disclosed which includes a rotary actuator having an output shaft, and a hydraulic power system for powering the actuator in either rotational direction. The output shaft of the actuator includes splined opposite free ends, and a radial arm is selectively attachable to either one of the ends. The outer end of the radial arm mounts a user engageable handle, and a load cell is mounted immediately adjacent the handle, so as to provide an output signal which does not include any force component from the weight or inertia of the radial arm. The apparatus also includes means for sensing the rotational position of the actuator, and the signals from the load cell and the position sensing means are fed to a computerized controller, which in turn controls the operation of the actuator in accordance with a predetermined program.
