Title:
ROBOT CONTROLLER
Document Type and Number:
WIPO Patent Application WO/1989/002623
Kind Code:
A1
Abstract:
In the conventional industrial robots, a maximum instructable speed is fixed irrespective of the kind of operation and the time constant during the acceleration or deceleration is fixed too, so that the load exerted on the motor that drives the robot arm will not exceed a maximum output. In the robot controller of the invention, a maximum speed and a time constant depending upon the content of operation of the robot are designated to the robot control axes (3) from a control unit (1) that includes a select table memory (4) for each kind of the operation that will be instructed to the robot. The robot therefore operates at high speeds without exerting increased burden on the operator.
