RobotEra STAR1 55-DoF High-Speed Bipedal Humanoid Robot
Full-size 171cm, 65kg general-purpose bipedal humanoid featuring 55 total Degrees of Freedom, 400 N·m peak joint torque actuators, 550 TOPS onboard AI compute, a documented 3.6 m/s outdoor running speed, and dual 12-DoF fully direct-driven XHAND 1 dexterous hands.
Editorial Rating Methodology (★ 4.9 / 5.0): This score is an internal editorial evaluation compiled by the RECIWO Labs editorial team—not a user poll or crowd-voted rating. It assesses published silicon compute efficiency (25%), optical/sensor/actuator engineering (25%), battery & thermal envelope (20%), SDK/software openness (15%), and price-to-specification value (15%) based on official manufacturer datasheets and public technical documentation.
