An Arduino is used to determine the servo’s current position versus the desired position, and it turns the motor accordingly with a BTS7960 motor driver.

The Pico Serial Servo HAT, meanwhile, is a compact and efficient serial servo controller with two powering options, two serial servo connectors, and two programmable buttons for customization.

Building a 3D motor printed motor is one thing, but creating a completely custom servo motor with encoder requires some significant engineering. In the video after the break [365 Robots] takes us ...
