Parts used across open-source robots
The servos, actuators, computers and sensors that several robots in the atlas list in their bills of materials. Each page shows which robots use the part, with the rows and quantities from their sources.
- Raspberry PiComputer, 20 robots, 20 units listedThe single-board Linux computer (Zero, 3, 4, 5 and Compute Module) many robots use as their onboard brain.
- ROBOTIS Dynamixel servosServo, 13 robots, 165 units listedROBOTIS's family of networked smart servos (X, MX and AX series), common in research arms, hands and humanoids.
- ArduinoMicrocontroller, 9 robots, 13 units listedThe Arduino microcontroller boards (Mega, Nano, Uno and compatibles).
- Feetech STS3215 servoServo, 9 robots, 73 units listedA serial bus servo from Feetech with a magnetic encoder, the actuator in the SO-100 family of arms and many robots derived from it.
- NVIDIA JetsonComputer, 8 robots, 8 units listedNVIDIA's embedded GPU computers (Nano, Xavier NX, Orin), used where a robot runs vision or learned policies onboard.
