The Unitree Go2 is an embodied AI quadruped robot measuring 70 by 31 by 40 cm standing and weighing approximately 15 kg with battery, priced from $1,600. Available in AIR, PRO, X, and EDU variants with speeds from 2.5 to 5 m/s. It features Unitree’s self-developed 4D LiDAR L2 with 360 by 90-degree hemispherical ultra-wide recognition and minimum detection distance of 0.05 m, upgrading the recognition system by 200 percent. The ISS 2.0 Intelligent Side-Follow System uses wireless vector positioning with 50 percent improved accuracy and over 30 m range. Rage Mode fully taps joint motor hardware for faster speed and responsive steering on gravel and slopes. Advanced AI Mode trained via large-scale simulation enables upside-down walking, adaptive roll-over, and climbing. Peak joint torque reaches approximately 45 N·m. The PRO variant adds 4G, GPS, and voice function. The X adds charging pile compatibility. The EDU adds a depth camera, foot-end force sensors, long-endurance 15,000 mAh battery providing 2 to 4 hours runtime, secondary development support, and fast charging. A new App enables HD image transmission, real-time remote monitoring, and graphical programming. Built-in 4G and eSIM provide stable remote connectivity. Continuous OTA upgrades are standard. The Go2 served as the robot dog superstar at the 19th Hangzhou Asian Games transporting discus and javelin. Targets research, entertainment, and inspection applications.
