The Unitree Go1 is described as the world’s first intelligence bionic quadruped robot companion of consumer level. Weighing 12 kg with folded dimensions of 0.588 by 0.22 by 0.29 m and 3 to 5 kg adaptive load, it features the SSS Super-sensing System with 5 sets of fisheye binocular depth sensing equivalent to approximately 20 groups of Intel RealSense sensing angles, covering 150 by 170 degrees. The ISS Intelligent Concomitant System uses patented wireless vector positioning for natural side-follow human-robot interaction. Available in Air, Pro, and Edu variants with speeds from 2.5 to 5 m/s. Joint torque reaches 23.70 N·m (body/thigh) and 35.55 N·m (knee). A built-in 16-core CPU with 384-core GPU at 1.5 TFLOPS provides AI processing. The Pro adds 5-pair super-sensing, app god view, and 4G. The Edu adds foot-end force sensors, Python programming, scientific programming interface, human sensing, and optional 2D or 3D radar. It achieved the first quadruped robot cluster automatic performance at the 2021 CCTV Spring Festival Gala. Targets household companionship and entertainment.
