For fun, and because optical encoders cost an arm and a leg. Initial BOM for 10 pieces places this thing around the price of a mechanical encoder. None of this is tested yet.

Today, we shall talk about how [Adam Bäckström] took a DS3225 servo and rebuilt it to improve its accuracy, then built a high-precision robot arm with those modified servos to show just how much of an ...

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 ...

This Arduino program is refered from: https://github.com/cswiger/dcservodrive by cswiger. It is used to control 2 DC motors and 2 optical encoders from printer head ...
