In a robot for training a rehabilitator, the driving of actuators is controlled to generate the forces acting in six directions at the distal end of a bi-articular arm device to reproduce the relationship between the muscular output of the upper or lower limb of the human body and the output direction at the distal end of the limb. The rehabilitator can experience the relationship between the outputs of his or her limb muscles and the output direction at the distal end of the limb. Thus, the six actuators are run in operation along a predetermined sequence. One or more of the actuators, selected so that the direction of the force generated at the distal end of the first link will be the selected direction, is run in operation. The rehabilitator holding the distal end of the first link may physically experience the direction of that force.

A training device measures, after its robot arm is mounted on a trainee, a change in angle of the joint axles of a limb of the trainee with angular sensors. Based on the angular change measured, a controller calculates an angular rate in the direction in which a load is applied, stores as the maximum muscular force a load at the time when the angular rate has exceeded a predetermined value, and stops applying the loads.

In a capacitance type of non-contact sensor for detecting the position of an object to be detected, such as dielectric material, a detection gain is changed in a first case where the object to be detected is placed in a first position and also in a second case where the object to be detected is placed in a second position, and an offset value is adjusted for each gain to bring an output value to a predetermined value. The adjusted offset values are stored in order to define a gain and an offset value at a point, where the offset values in the first and second cases are closest, as adjustment values.

A system for rehabilitation training is able to specify the muscle of a person in need of rehabilitation, and also to help the person to set a proper goal of training. To this end, the system includes a trainer device for measuring living data of the person and for training him or her, and a data server for keeping the living body data of the person measured by the trainer device. The system further includes a menu formulator. When the person is to undergo the process of rehabilitation, the menu formulator compares his or her living body data measured by the trainer device to his or her living body data measured when he or she was not impaired and kept in the data server to find out a difference therebetween. A menu for rehabilitation is formed based on the difference, so that rehabilitation effects will be enhanced.
