The Unitree R1 EDU Pro B (U4) Humanoid Robot is a full-size bipedal research platform developed by Unitree Robotics, designed for advanced manipulation research and embodied AI development. It operates across laboratory and research environments where contact-rich interaction and haptic data collection are central requirements. Compared to the U3 configuration, the U4 variant integrates tactile sensing across both dexterous hands, making it the higher-capability tier within the R1 EDU Pro B line. With 40 actuated degrees of freedom distributed across its legs, waist, arms, and hands, it is built to support complex whole-body motion tasks in structured research settings.
The robot's perception and response capabilities extend beyond vision, incorporating a full spatial audio array and binocular depth camera module system that together support environment awareness and human interaction scenarios. Its onboard AI computing module delivers substantial inference performance, enabling real-time policy execution and learning-from-demonstration workflows without offloading to external hardware. The open tactile sensor interfaces allow synchronized joint and haptic data streaming through standard robotics middleware, making it straightforward to integrate into imitation learning and reinforcement learning pipelines. With hot-swap battery support and approximately one hour of runtime, the system accommodates extended research sessions with minimal downtime. Designed to serve robotics research institutions, university labs, and advanced education programs, it provides the hardware foundation needed to study contact-aware manipulation, in-hand reorientation, and haptic-guided grasping at a professional research level.

Key capabilities of the Unitree R1 EDU Pro B (U4) for haptic research, dexterous manipulation, and embodied AI development.
33 tactile sensors per Dex3 hand provide real-time contact feedback during grasping and manipulation. Enables force-sensitive AI model training with rich contact data.
Two Dex3 hands (7 DOF each, 33 tactile sensors per hand) support finger-level manipulation with force sensing. Ideal for teleoperation-based data collection.
SDK2, ROS 2 MoveIt2, and Isaac Sim with open tactile sensor interfaces enable learning-from-demonstration and reinforcement learning research with synchronized joint and haptic data.
The U4 adds tactile sensing over the U3 configuration, making it the tier of choice for studying contact-rich manipulation, in-hand reorientation, and haptic-guided grasping.
