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 ...

For example, to use a DC motor in a robot leg, one might expect to need a gearbox, a motor driver, plus an encoder for position sensing.

A growing trend in encoder technology is the integration of additional sensors to add diagnostic functions and handle thermal and/or vibration issues. For example, an encoder mounted on a robot’s arm ...
