Unitree GO-M8018-6 Motor Reverse Engineering
The Unitree GO-M8018-6 motors are being reverse-engineered to unlock their proprietary driver. This process involves analyzing the motor's components and firmware, which has been encrypted. The goal is to create an open-source firmware that could expand the motors' accessibility and improve the associated Go2 robot's functionality.
- ▪The GO-M8018-6 motors are similar to the previous GO-M8010-6 motors from Unitree.
- ▪Thomas Flayols is reverse-engineering the motor's proprietary driver using publicly available documentation.
- ▪The reverse-engineering process has successfully decrypted the firmware, allowing for custom firmware development.

Unitree GO-M8018-6 Motor Reverse Engineering No comments by: Maya Posch May 23, 2026 Title: Copy Short Link: Copy People seem to be rather into the Unitree Go2 quadruped robot, if only for the low price tag. But perhaps more interesting are the motors that propel it — they appear to be similar to the Go1’s GO-M8010-6 motors that Unitree also sells, with [Thomas Flayols] currently working on reverse-engineering its proprietary driver using the publicly available documentation for that motor and some reverse-engineering. These motors are an assembly that includes a reducer, magnetic encoder, 3-phase inverter, current sensing, an RS-485 bus and a Cortex-M0-based CMS32M57xx MCU, all in a very capable package intended for robotics applications where a compact actuator is needed.
