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 ...

The actuator combines a high precision harmonic drive gear component with a pancake brushless servo motor. A single-turn 14 bit (16384 cpr) gear output encoder has been integrated along with a single ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was po… ...
