Document Type and Number:
Japanese Patent JP5209924
Kind Code:
B2
Abstract:
An operating status of a motor in a drive unit is analyzed to extend the life of the motor. A wearable motion assistive device 1 includes a shoulder joint mechanism 5 and an elbow joint mechanism 6 for aiding a movement of the shoulder joint and the elbow joint, and a control unit 100 having a control circuit for controlling drive units 11 for the shoulder and elbow joint mechanisms 5 and 6. The control unit 100 controls the drive units 11 based on a physical quantity and a biosignal detected by an angle sensor, a torque sensor, and a biosignal detecting sensor. A controller in the drive unit 11 includes a motor monitoring unit for monitoring an operational status of the motor, and a motor control unit for limiting a drive signal supplied to the motor based on a monitoring result provided by the motor monitoring unit, in order to prevent an overload state of the motor.
