## What it is
The Open Robot Actuator Hardware repository contains open-source mechanical and electronic designs for a low-cost, torque-controlled modular robot actuator built from brushless motors, 3D-printed and off-the-shelf parts. It includes designs for complete robots such as the Solo8/Solo12 quadrupeds, the Bolt biped, TriFingerEdu manipulator, and various leg and actuator modules.

## Use cases
- build your own open-source quadruped robot
- low-cost torque-controlled actuator module for legged locomotion research
- 3D printed robot designs for university robotics labs
- open hardware electronics for brushless motor control
- reproduce a research robot platform from open drawings
- build a biped or finger manipulator from open-source parts

## When to choose
- you want to physically build a torque-controlled legged robot or manipulator from open designs
- you need low-cost, reproducible actuator hardware for locomotion or reinforcement-learning research
- you want complete mechanical drawings and electronics schematics under a permissive BSD-3 license

## When to avoid
- you only need robot simulation or control software without building hardware
- you need a ready-made commercial robot rather than a DIY build
- you expect a software library - this repo is hardware designs, with software hosted in sibling repositories

## Facets
- artifact type: dataset
- maturity: stable
- function: robotics, embedded, documentation
- domain: robotics, hardware, simulation, education
- platform: embedded, iot, cross-platform
- tags: open-hardware, robot-actuators, legged-robots, brushless-motors, 3d-printed-robots, torque-control, quadruped, biped, mechanical-designs, electronics
