MECHADUINO- CLOSED LOOP STEPPER SERVOS FOR EVERYONE
[hackaday.com]
The Arduino-sounding bit of the name comes from their full compatibility with the Arduino development environment. The brains of the board is the compatible, SAMD21 ARM M0+ chip. They wanted the board to be as accessible as possible. On top of this, it also allows the user to use any control algorithm they want for the board. Most industrial controllers are limited to PID control, for returning to the last sent position. Opening up the control allows for interesting applications, such as motors that behave like mass spring damper systems, or electronically gearing the input of one stepper to the output of another.
The board supports lots of standard communication protocols, but the acceptance of regular stepper inputs make it extra interesting. It can become a drop-in replacement for the motors on a normal CNC or 3D printer, which have full closed loop control as shown in the video after the break.
