<p><P>PROBLEM TO BE SOLVED: To aim at analyzing the operation state of a motor of a drive unit to prolong life of the motor. <P>SOLUTION: 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 biosignals 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. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
