Unitree released the 19-second video on X, demonstrating the G1’s exceptional balance and precision. This follows earlier footage from the same month, where the G1 displayed its ability to execute a 720-degree spinning kick, skillfully disarming a person holding a baton.

The company has been consistently updating the robot’s algorithm, allowing it to learn and perform increasingly sophisticated movements with precision and control.

Unitree G1 with advanced motion and stability

The G1’s design incorporates 23 degrees of freedom (DoF), providing impressive stability and coordination. Standing at 4.33 feet (1.32 meters) and weighing 77 lbs (35 kg), it features a foldable structure for compact storage, measuring just 27 x 17.7 x 11.8 inches.

Its cutting-edge technology includes 3D LiDAR, a RealSense depth camera, and a noise-canceling microphone array for voice command recognition. G1 operates on a 9,000-mAh quick-release battery, offering up to two hours of runtime with fast-swapping capabilities. The robot is powered by an 8-core high-performance CPU, which controls its powered joints across the arms, legs, and torso. This enables agile movement and a walking speed of up to 6.5 feet per second (4.5 mph).

The Unitree team has emphasized the importance of controlled use, cautioning against modifications or programming the robot for combat purposes.

Before physical production, G1’s training takes place in a virtual environment using Nvidia’s Isaac Simulator. This allows the robot to learn complex behaviors through reinforcement learning, refining its abilities in a controlled digital setting. The learned actions are then seamlessly transferred to the physical model through a process called Sim2Real, ensuring accurate real-world execution.

Open-source innovation

In an effort to accelerate advancements in humanoid robotics, Unitree has introduced an open-source full-body motion dataset aimed at improving humanoid motor control and coordination. This dataset enhances the movement fluidity of Unitree’s core models, including the H1, H1-2, and G1, and facilitates more human-like motions, such as dancing and dynamic repositioning.

The dataset, developed using LAFAN1 motion capture technology, is fully compatible with Unitree’s humanoid systems and integrates an advanced redirection algorithm. This algorithm optimizes motion planning through the application of interactive mesh processing and inverse kinematics, taking into account posture constraints, joint articulation, and velocity parameters.

By making this dataset available to the broader research community, Unitree seeks to encourage innovation in humanoid robotics and drive forward the field’s real-world applicability.

Unitree’s humanoid lineup continues to set benchmarks, with the H1 model achieving a Guinness World Record in March 2024 for sprinting at a speed of 7.38 mph (3.3 m/s). The G1, while optimized for compactness and affordability, serves as an adaptable research platform, broadening access to advanced humanoid robotics in both academic and commercial settings.

How Fix4Bot.com Can Diagnose and Repair Damages to Unitree G1 and Other Humanoid Robots

Given the sophisticated nature of humanoid robots like the Unitree G1, it’s crucial that any damages or malfunctions are accurately diagnosed and effectively repaired to ensure optimal performance and long-term functionality. Fix4Bot.com specializes in providing comprehensive diagnostic and repair services for advanced robotics, such as the G1. Here’s a step-by-step overview of how Fix4Bot.com addresses such needs.

1. Initial Assessment and Diagnostics

First, the process begins with an initial assessment where the robot is connected to specialized diagnostic tools. Fix4Bot.com utilizes state-of-the-art diagnostic software that interfaces directly with the robot’s 8-core high-performance CPU. This software checks all connected systems such as LiDAR, depth cameras, and the noise-canceling microphone array.

The diagnostic phase includes:

• System Health Check: Verifying that the CPU is functioning correctly and that no components are overheating or underperforming.
• Joint and Actuator Testing: Inspecting all 23 degrees of freedom (DoF) to ensure that each joint is moving within its designed parameters and that actuators are not experiencing any resistance or power issues.
• Sensor Validation: Checking that the 3D LiDAR, RealSense depth camera, and microphone array are providing accurate data and are in good working condition.
• Battery and Power Supply Verification: Testing the 9,000-mAh quick-release battery to ensure it charges properly and holds a charge for the expected duration.

2. Error Log Analysis and Software Updates

Robots like the G1 maintain error logs that record any anomalies detected during operation. Our technicians review these logs to identify recurring issues or one-time errors that might indicate underlying problems. Furthermore, any outdated firmware or software is updated to the latest version provided by Unitree, which often includes bug fixes and performance improvements.

3. Hardware Inspection and Repair

The next step develops if the diagnosis identifies a hardware issue like a faulty sensor or damaged actuator involves a thorough physical inspection. Our team is equipped with the necessary tools and replacement parts to address specific hardware issues, which might involve:

• Replacing damaged limbs or joints.
• Swapping out faulty sensors or cameras.
• Replacing the battery if it no longer holds a charge effectively.

To ensure high-quality repairs, Fix4Bot.com uses only genuine Unitree parts whenever available or high-quality, compatible alternatives from trusted suppliers.

4. Software and Algorithm Refinement

Another common area of repair might involve the robot’s control algorithms. If the robot fails to perform a specific action, such as executing a standing side flip or a spinning kick effectively, our team can fine-tune the underlying algorithms. Since the G1 utilizes reinforcement learning within Nvidia’s Isaac Simulator, we can use a similar virtual environment to test and refine movements before transferring the updated behavior to the physical robot.

• Identifying motion issues involves simulating the action within the Isaac Simulator and making necessary adjustments.
• Updating the control software might involve re-instructing the robot to learn new or refined actions using the open-source full-body motion dataset provided by Unitree.

5. Comprehensive Testing Post-Repair

Once any required repairs are made, the final step is a thorough testing phase where the robot is put through a series of functional tests. This includes verifying that:

• All hardware components are functioning correctly.
• The software is operating with the latest updates.
• All movements and actions are executed as designed.
• The robot maintains balance and performs complex maneuvers such as dynamic repositioning and any learned actions (e.g., dancing).

6. Preventive Maintenance and Recommendations

After successfully diagnosing and repairing any damages, Fix4Bot.com also offers a preventive maintenance plan to help avoid future issues. Regular check-ups can include:

• Regular battery checks and replacements.
• Periodic sensor calibration.
• Software updates and system health checks.
• Inspections of joints and actuators for wear and tear.

Conclusion

The Unitree G1 is a revolutionary humanoid robot that showcases exceptional agility and advanced capabilities. However, like all complex machines, it can sometimes need professional diagnosis and repair to maintain its peak performance. At Fix4Bot.com, we ensure that any damages are accurately diagnosed and effectively repaired, keeping your robot in top working condition.
