Unitree Go2 is an intelligent bionic quadruped robot dog in the Unitree Go2 robot series. It is equipped with an ultra-wide 4D LiDAR recognition system, app-based interaction, OTA software upgrades, and locomotion capabilities for complex terrain. Official sources describe multiple Go2 configurations including Air, Pro, X, and EDU. Supported configurations include features such as wireless vector positioning, 3D LiDAR mapping, HD image transmission, and graphical programming.
Highlights
- Ultra-wide 4D LiDAR recognition with hemispherical scanning and minimum detection distance as low as 0.05 m.
- Rage Mode uses the hardware capabilities of the joint motors for faster speed, more responsive steering, and stable agile movement on terrains such as gravel and slopes.
- Peak joint torque is listed as about 45 N.m for the largest joint motor on supported configurations.
- Intelligent Side-follow System 2.0 uses wireless vector positioning and control technology, with remote control distance over 30 m in open environments without interference or blocking.
- 3D LiDAR mapping with L2 LiDAR and a dedicated app can construct a point cloud map within a certain area and specify a path for autonomous movement.
- OTA upgrades allow the robot, with user authorization, to connect to a cloud-based OTA service and upgrade its programs.
- The app supports HD image transmission and real-time remote monitoring; transformation and quality vary in different network environments.
- Go2 supports actions and poses such as jumping, stretching, shaking hands, cheering, pouncing, and sitting down.
- Wireless connectivity listed by Unitree includes Wi-Fi 6, Bluetooth, and 4G on supported configurations.
