Bruce
Bruce is a compact, kid-sized humanoid robot designed as an open-platform for advanced robotics research and education. Standing at 70cm tall and weighing just 4.8kg, it features a lightweight carbon fiber composite structure for durability and agility. With 16 degrees of freedom, including 5 DOF per leg and 3 DOF per arm, Bruce excels in dynamic bipedal locomotion such as walking, running, jumping, and even advanced maneuvers like single-leg hopping or yaw rotations. Powered by proprietary Koala BEAR proprioceptive actuators with liquid cooling, it delivers explosive power and real-time compliance for unstructured environments. Equipped with a high-frequency 6-DOF IMU, 4 contact sensors, and a 6TOPS onboard computer supporting deep learning frameworks, Bruce enables autonomous navigation, whole-body control, and sensor-based adaptation. Its modular, repairable design and open-source software/hardware foster rapid prototyping in locomotion, perception, and human-robot interaction, making it ideal for testing algorithms in real-world scenarios.
