  • Patent number: 5770834
    Abstract: A robot control system that includes a controller that is capable of controlling the current supplied to a current-controlled tool mounted on the robot. The controller is capable of accepting operator inputs and the robot is coupled in data communication to the controller. A tool which is controlled in at least one manner by electric current is mounted on the arm of the robot. The controller is coupled in data communication to a current source and is programmed to control the current supplied to the tool. The controller is also capable of receiving inputs from an operator and is capable of ramping the current supplied to the tool from an initial current level to an operator selected current level over an operator defined and inputted selected time. The controller can also ramp the current supplied to the tool from the selected current level to a third current level over a second operator selected and inputted time period.
