Unitree G1 Edu Ultimate E U7 Humanoid Robot with Revo 2 Basic Hands (G1EDU-U7)

The defining feature of Unitree G1 EDU Ultimate E U7 is the pair of BrainCo Revo2 Basic five-finger dexterous hands.

BrainCo specifies Revo2 at 11 mechanical DOF with 6 active actuators, approximately 383 g per hand, at least 50 N five-finger grip force, at least 15 N pinch force, and approximately 0.1° repeat control precision. Full flexion/extension is rated at ≤0.65 s.

The six active commands correspond to the thumb, auxiliary thumb/abduction channel, index, middle, ring and little finger. Unitree’s official BrainCo hand service maps these commands into DDS topics for left and right hands, while BrainCo’s own SDK provides Python and C/C++ control support.

Revo2 Basic supports RS-485 and CAN FD communication. Higher BrainCo Revo2 Pro/Touch variants add EtherCAT, while the Touch tier adds multimodal fingertip tactile sensing. U7 uses the Basic hands, so it should not be described as a tactile-hand configuration.

What Revo2 Basic is good at

• Humanlike five-finger grasp shapes
• Fast open/close motion
• Whole-hand grip and pinch research
• Bimanual manipulation
• Teleoperation and data collection
• Imitation-learning datasets
• ROS 2 / SDK-based hand integration

What Revo2 Basic does not provide

Revo2 Basic does not include the fingertip tactile modules of Revo2 Touch. If your research depends on pressure, tangential force, contact direction or proximity sensing at the fingers, compare U8 instead.

U7 belongs to the G1 EDU family, so official secondary development is supported. The current development ecosystem is stronger than most competitor pages explain.

Unitree publishes SDK2, ROS resources, robot-description files, reinforcement-learning examples and an XR teleoperation stack. The XR project currently supports the G1 29-DOF body and BrainCo dexterous hands, including recent controller-input support.

Unitree also publishes an official brainco_hand_service bridge. It converts BrainCo serial hand communication into Unitree DDS topics, allowing left/right hand commands and states to integrate with the Unitree SDK2 environment.

BrainCo separately publishes its own Revo hand SDK in Python and C/C++, along with ROS 2 drivers and digital assets for modern simulation workflows. BrainCo also maintains a dedicated Unitree G1 + Revo2 integration repository covering both 23-DOF and 29-DOF G1 bodies.

Large-scale policy training should still be performed on external GPU infrastructure. The onboard Jetson is best treated as a robot-side inference and development module rather than a replacement for a training server.

Unitree’s current official G1 EDU family specification lists up to 120 N·m maximum knee torque and an approximately 3 kg arm-load reference, with arm payload changing substantially according to posture and reach.

Some U7 seller pages still show 90 N·m. That appears to be inherited from older or Basic-G1 specification tables. For the current EDU body, this page uses Unitree’s manufacturer-level 120 N·m EDU reference while still advising buyers to confirm the exact hardware revision.

U7 uses the standard G1 EDU 9000 mAh quick-release battery with approximately two hours of manufacturer-reference runtime. Hand activity, Jetson workload, locomotion and sensing all affect real runtime.

Current U7 specialist listings commonly include the G1 EDU Ultimate E humanoid, two BrainCo Revo2 Basic hands, manual controller, one 9000 mAh battery and the applicable G1 EDU warranty.

The final quotation controls the supplied package. Do not assume extra batteries, transport case, Touch/tactile hands, camera mounts or third-party teleoperation hardware are included unless explicitly listed.

• Basic is not tactile: U7 Revo2 Basic does not include the Touch tactile module.
• 41 vs 40 DOF: older reseller tables can show 40; current 29-DOF body + 12 active hand DOF gives 41.
• Hand software matters: BrainCo hands use their own SDK/control layer and should not be treated as drop-in Dex3 replacements.
• Serial integration requires planning: Unitree’s BrainCo service bridges hand serial communication into DDS.
• Arm load remains posture dependent: Unitree’s ~3 kg EDU arm reference is not a universal payload at full extension.
• 100 TOPS is robot-side inference compute: large-scale model training still belongs on external GPU systems.
• Humanoid safety remains essential: maintain adequate operating clearance and supervised development practices.
