Very nice project. As described in the video, for servo motor v dumb stepper, servo motor is more efficient and servo motor won’t miss steps, or at least not without being able to provide a warning.

You could build a servo out of junk DC motors with a “3 cent” microcontroller, then. We thank [sarinkhan], [Diede] and [BaldPower] for sharing this with us!

For this unit, the PID controller board needs to output a 12-V PWM signal to control motor speed, and use an analog-to-digital converter (ADC) channel to sense the position of the actuator.

Specifically, servo motors and robots are transforming additive applications and revolutionising the way prototypes, parts and products are made. Additive and subtractive manufacturing techniques are ...

AC servo motors are rotary motors that allow for a precise control in terms of angular position, acceleration, and speed, where it is a combination of specific parts that include an electric motor ...

Renesas announced its highest-perfomance RZ/T2M motor control microprocessor units for applications such as AC servo drives and industrial robots.
