Abstract

Official abstract text for this publication.

In a trajectory control device ( 10 ) for an articulated robot, a first dynamic characteristic calculation unit ( 300 ) is provided with a high-frequency cutoff characteristic having a cutoff frequency which is lower than the natural oscillation frequency of the robot, performs filtering processing with respect to a joint-angle command value (θc), and outputs a processed joint-angle target value (θd). A second dynamic characteristic calculation unit ( 400 ) is provided with a high-frequency cutoff characteristic having a cutoff frequency which is lower than that of the first dynamic characteristic calculation unit ( 300 ), performs filtering processing with respect to the output from a coupling-torque compensation command value calculation unit ( 200 ), and outputs a processed coupling-torque compensation value (cd).

First claim

Opening claim text (preview).

The invention claimed is: 1. A trajectory control device for an articulated robot that drives a plurality of joint axes by a motor so that a tool attached to the articulated robot makes a desired motion, the trajectory control device comprising: a joint-angle command value calculation unit that calculates and outputs a joint-angle command value θc for each of the joint axes to realize the desired motion of the tool; a coupling-torque compensation command value calculation unit…
