Robot Programming

Robot Programming - Robots can be programmed by the following methods;

(i) Manual method

(ii) Walk through method

(iii) Lead through method

(iv) Off line programming.

Manual method is used for low technology robots meant for short work cycles. Manual method is more like setting up a machine, rather than programming. It involves setting mechanical stops, cams, switches or relays in the robot's control unit.

The walk through method is appropriate for spray painting and, is welding robots.

In this method, initially, the programmer manually moves the robot's arm and hand through the motion sequence of the work cycle. Each movement ill recorded into the memory of the robot for subsequent play back during production. The lead through method is easy and convenient. A teach pendant which is a small hand held device with switches and dials is used to control the robot's physical movements. Each motion is recorded into memory for future play back during the work cycle.

Off line programming method involves the preparation of the robot program off line, in a manner similar to NC part programming. Off line robot programming is typically accomplished on a computer terminal. After the program has been prepared, it is entered into the robot memory for use during the work cycle.

The advantage of this programming method is that programming can be done while the robot is still in production on the preceding job, thus production time of the robot is not lost to delays in teaching the robot a new task. This ensures higher utilisation of the robot.
