Robot Contact Sensor

This electrical contact probe is made up of a standard pogo pin and receptacle and a nylon screw, as seen in Fig. 1.

The nylon screw 3 has a hole drilled through it and the pogo pin receptacle 2 is press fit into that hole. The pluggable pogo pin 1 snaps into the receptacle. The contact pallet surface is wired so that when the contact sensor makes contact with the pallet, a circuit is completed to the robot input module, thus enabling the robot to detect contact.

In use, the robot moves to a point close to the pallet and then moves toward the pallet until contact is made. Once contact is made, the robot switches direction and moves away, at a slower increment, until contact is broken. The robot, moving back and forth, converges upon the point using interval (increment) halving. The point is converged to within a specified tolerance, limited by the accuracy of the robot.
