[Kato RC Publishing Article #49] $60 Robot Muscle — The BLDC Servo Revolution Made with 3D Printers

It is Arduino-based and supports multiple microcontrollers such as AVR, STM32, ESP32, and RP2040. FOC is an algorithm that controls the magnetic field of a BLDC motor in real time. In the past, it was ...

[Kato RC #34] Chess pieces that move on their own—The open-source "MiniBots" project is changing the common sense of swarm robotics

On a chessboard, a pawn moves forward on its own. A knight jumps in an L-shape. A rook slides in a straight line. All 32 pieces are independent robots. Moreover, it is open-source and anyone can build ...

servo motor

It’s little secret that stepper motors are everywhere in FDM 3D printers, but there’s no real reason why you cannot take another type of DC motor like a brushless DC (BLDC) motor and use that instead.
