Actuators that are powerful, accurate, compact, and cheap are like unicorns. They don’t exist. Yet this is what [3DprintedLife] needed for a robotic camera arm, so he developed a custom 3D printed high torque strain wave gearbox to be powered by a cheap NEMA23 stepper motor. Strain wave gears, otherwise known as harmonic drives, are not an uncommon

This instructable describes how to make an ultrasonic “radar-style” display using an Arduino microcontroller, an ultrasonic sensor, and a small stepping motor. An optional sensor modification allows multiple objects to be detected with each ping. Construction is simple … all you need are two drills, a sharp knife, a pair of side-cutters , and a
