My youtube channel is ALMA Industries

This is a short demo of an actuator I put together (on my channel, video is titled CH003 FN1: ACTUATOR). The actuator is first sketched out, 3D printed in pieces, assembled together, and controlled via PID running on a microcontroller. Ultrasonic distance sensor is included in the close-loop feedback system to prevent the actuator from running into the ceiling (shown in the second half of the clip, and discussed more in the full video).

There are a few modes. The first is 'don't touch the ceiling' (Ultrasonic Distance Sensor to keep a distance from the wall, hand, etc). The second is to have the actuator distance sensor follow a second distance sensor...so when one goes up the other follows going up, and when one down the other down.

Comments, questions, or new ideas are welcome.
