Abstract

A body-worn motion assisting device (1) comprises a shoulder joint mechanism (5) for assisting the user to move a shoulder joint, an elbow joint mechanism (6) for assisting the user to move an elbow joint, and a control unit (100) having a control circuit for controlling a drive unit (11) of the shoulder joint mechanism (5) and an elbow joint mechanism (6). The control unit (100) controls the drive unit (11) according to the physical quantities and biosignal detected by an angle sensor, a torque sensor, and a biosignal sensor. A control section of the drive unit (11) includes a motor monitoring block for monitoring the operation state of a motor and a motor control block for limiting the drive signal sent to the motor depending on the results of monitoring by the motor monitoring block so that the motor does not become under overload.

Description

technical field [0001] The present invention relates to a motion assisting device and a maintenance and management system for the motion assisting device, in particular to a motion assisting device and a maintenance and management system for the motion assisting device that manage the operating state of a drive unit. Background technique [0002] In recent years, various assisting devices have been developed to assist the movement of physically handicapped persons and elderly persons (for example, refer to Patent Document 1). For example, the wearable motion assisting device described in Patent Document 1 includes a joint that rotatably connects a plurality of arms to each other, an actuator that rotates one arm relative to the other arm, and an angle sensor that detects the rotation angle of the arm. [0003] For example, there is provided a rotation angle detection device in which detection elements are arranged in the radial direction of the rotation shaft (for example, r...
