Abstract
The disclosure teaches a novel exercise apparatus. This apparatus does not generate load momentum. The apparatus is based around a series elastic torque sensor and contains an intelligent servo drive with reduction gear to control a variable speed rotating motor shaft. The combination of the motor, gear reducer, spring, angle measurement sensors (position sensors), and intelligent motor controller is a series elastic actuator which is the basis for the exercise device. The exercise device also contains a load transfer mechanism adopted to provide an interface between an individual and the torque sensor. The apparatus allows for isokinetic, isometric, isotonic, and variable force modes of exercise without hardware configuration.
