Unitree’s G1 becomes world’s first humanoid robot to walk in -53°F

China’s Unitree has achieved a significant milestone in humanoid robotics by demonstrating its G1 robot’s ability to autonomously walk over 130,000 steps in extreme cold conditions reaching –47.4°C (–53°F) in the Altay region of Xinjiang. The robot traced a Winter Olympics emblem across a snowfield measuring approximately 186 by 100 meters, marking the first confirmed instance of a humanoid robot sustaining autonomous walking in such severe cold. To withstand the harsh environment, engineers equipped the G1 with an insulated orange puffer jacket and plastic leg covers to protect critical components like joints, actuators, and batteries from freezing. The G1 robot is a compact biped standing about 127 cm tall and weighing 35 kg, featuring between 23 and 43 joint motors with a maximum torque of 120 Nm. It incorporates advanced sensors such as 3D LiDAR, Intel RealSense depth cameras, and a noise-cancelling microphone array, powered by a
