Abstract

It is very difficult to locate a specific position in the robotic work area when using the pendant as a positioning means. The bulky fingers, at the end of the robotic arm, provide no real reference point which can be guided to the desired position. Accordingly, the pendant position pointer provides the "fine" reference point to aid the user or operator.

Pendant Position Pointer

It is very difficult to locate a specific position in the robotic work area when using the pendant as a positioning means. The bulky fingers, at the end of the robotic arm, provide no real reference point which can be guided to the desired position. Accordingly, the pendant position pointer provides the "fine" reference point to aid the user or operator.

The pendant position pointer 10 is an electrically controlled toothpicklike device which is attached to the gripper 12 or other end of arm unit of the robot. The device 10 may be extended and retracted by simply transmitting a simple digital output pulse to the control thereof. The device is located on the side of the gripper, in a spot which will not interfere with gripper operation. The device 10 could be located behind the pad 14 on one of the fingers
16. Referring to the figure, the toothpicklike device 10 is located in a cylindrical container 18, and is shown in the extended position.

A button on the pendant could control its operation. Pushing the button the first time would extend the pointer 10 to assist in locating a particular point. This would give the user a much finer reference point by means of which to guide the manipulator. Once the desired position has been obtained, the operator would push the same button again, causing the pointer to retract. The The retraction would protect the pointer when not needed. The offset of the pointer to the center of the gripper opening woul...
