Sensors Your Robot Will Love You For Adding

(Yes it's an old picture, but) as you see, we have our tools ready to work on robots.

This is just a miscellany of sensors your robot can use from time to time.

Not all these ideas were mine, but they are useful and need to be put up for all roboticists to use as needed.

Below is a sample circuit you could use with the pressure roller to tell if something is slipping from the robot's grip.

If it slips, release pressure, lower the gripper to the original position and reclamp the grip with slightly higher pressure and try lifting the object again. Repeat this until the object does not slip (causing the wheel to rotate).

And below is a sample robot schematic showing several sensors being used.

Remember that you can incorporate more than one sensor at a time to get different effects. For instance, I did not draw it, but you could use the Slip Sensor as one "finger" or "claw" on your robot gripper, and then add the Pressure Sensor under it, so it does double duty of checking if the object is slipping and at the same time tell how much pressure is being applied.

I hope some of these ideas prove useful.
