## What it is
moteus is an open-source brushless DC servo motor controller project containing firmware, PCB hardware designs, and client-side libraries for the mjbots moteus actuator family. It provides high-performance motor control over CAN-FD for building robots and other machines.

## Use cases
- control brushless DC motors for a robot
- build a quadruped or legged robot actuator
- drive servo motors over CAN-FD from a Raspberry Pi
- flash and configure moteus motor controller firmware
- diagnose and tune brushless servo motor performance
- design custom motor controller hardware from open PCB files

## When to choose
- you need a compact, high-power brushless motor controller with open firmware and hardware designs
- you are building robots and want CAN-FD based multi-actuator control
- you want to buy assembled boards (mjbots.com) and use the open-source firmware and Python client library

## When to avoid
- you need a pure software-only solution with no hardware purchase
- you are working with stepper or DC brushed motors rather than brushless servos
- you are uncomfortable working with high-power electronics and embedded firmware

## Facets
- artifact type: application
- maturity: active
- function: embedded, robotics, developer-tools, sdk
- domain: robotics, embedded-systems, hardware
- platform: embedded, cpp, python
- tags: brushless-motor-controller, can-fd, servo-actuator, firmware, pcb-designs, motor-control, stm32, automation, linux
