Title:
ROBOT CONTROL DEVICE AND METHOD FOR CONTROLLING ROBOT
Document Type and Number:
Japanese Patent JP2011005571
Kind Code:
A
Abstract:

To provide a robot control device controlling a robot.

The robot control device includes a link 3 rotatable with respect to a base body 1, a motor 4 driving the link 3, a reducer 5 transmitting torque of the motor 4 to the link 3 with a speed reduction ratio N, an angle sensor 6 detecting the rotational angle θM1 of the motor 4, an angular velocity sensor 12 detecting angular velocity ωL1 of the link 3 with respect to the base body 1, and a calculating unit 15 calculating rotational angle of the link 3 using a high frequency component of a first frequency fH or higher out of the integral value of the angular velocity ωL1 and a low frequency component of a second frequency fL or lower out of θM1*N, the first frequency fH being different from the second frequency fL. Thus, the influence of bias drift of the angular speed sensor 12 can be eliminated, and a signal of an angle with specific frequency intensified or deleted can be obtained.
