Contact for pricing
Star 1 (STAR1) is a full-size bipedal humanoid robot developed by RobotEra (星动纪元), a Beijing-based embodied-AI company. It integrates the company's self-developed dexterous hands, integrated joints, and multimodal sensing with onboard high-performance computing for learning-based control. RobotEra positions it as a research and demonstration platform for embodied intelligence rather than a consumer product.

Overview
Star 1 (STAR1) is a full-size bipedal humanoid robot from RobotEra, a Beijing-based company developing a full-stack, self-developed embodied-AI platform spanning both hardware and software. The robot is built around RobotEra's own integrated joint modules, which combine frameless torque motors, precision planetary reducers, high-precision encoders, and drivers into single units.
The platform pairs high-performance onboard computing with multimodal sensing — including fingertip tactile arrays, depth-vision cameras, microphone arrays, and a facial interaction screen — to support reinforcement learning, imitation learning, and end-to-end model research. Its dexterous manipulation comes from RobotEra's XHAND1, described by the company as its first product-level robotic dexterous hand.
RobotEra presents Star 1 as a demonstration and research platform for general-purpose humanoid capabilities, and the robot has been shown publicly in outdoor agility and locomotion demonstrations rather than offered as a finished commercial unit.
