China’s robotics company Unitree has set a new benchmark with its H1 humanoid robot. The H1 became the first robot to execute a standing backflip without relying on hydraulic systems. Unlike Boston Dynamics’ Atlas, which uses heavy hydraulic mechanisms, the H1 is powered by innovative M107 electric joint motors. This design not only improves efficiency but also makes the robot cleaner and more streamlined.
Unitree’s proprietary motors deliver an impressive peak torque of 360 Nm. These motors are also utilized in the company’s B2 quadruped robot, demonstrating their versatility. The H1’s legs feature five degrees of freedom, offering a wide range of motion. Internally routed cables enhance the robot’s aesthetics and protect crucial components, reflecting the engineering team’s attention to detail.
A Leap in Innovation: The Backflip and Beyond
The H1’s standing backflip is a significant milestone in robotics. Unitree used reinforcement learning simulations to teach the robot this challenging maneuver. Although the robot needed a small corrective jump upon landing, the feat showcased a major advancement in humanoid agility. This achievement, coupled with the absence of hydraulics, positions the H1 as a unique contender in robotics.
Beyond acrobatics, the H1 demonstrates practical skills essential for real-world applications. It can walk at high speeds, climb stairs, perform standing jumps, and even dance. Remarkably, it holds the world speed record for humanoid robots, reaching 3.3 m/s (7.4 mph). Unitree aims to boost this to 5 m/s in its future commercial version, signaling ongoing innovation.
Designing for the Future: Practicality Meets Scalability
Standing 1.8 meters tall and weighing 47 kilograms, the H1 combines size and functionality. It can carry payloads up to 30 kilograms, making it suitable for industrial and logistical tasks. Its head-mounted sensor array integrates advanced technologies like 3D LiDAR and Intel RealSense depth cameras. These tools allow the robot to navigate and interact with its environment with precision.
Powering the H1 is an 864-Wh replaceable battery, ensuring sustained performance during demanding tasks. The robot’s lightweight design and scalable technology suggest potential for widespread adoption. At an estimated price of $90,000, the H1 remains a development prototype but hints at affordability compared to similar robots.
Bridging Acrobatic Prowess and Practicality
While its backflip has drawn attention, the H1’s true potential lies in its versatile design. Its ability to combine advanced acrobatics with practical capabilities sets it apart. With plans to release a commercial version within the next decade, Unitree is shaping the future of humanoid robotics.
The H1’s achievements go beyond impressive stunts. They underline the growing role of robotics in commercial and industrial applications. Unitree’s focus on efficient electric motors and innovative design principles reflects its commitment to sustainability.
As robotics continues to evolve, Unitree’s H1 represents a step forward in merging agility and usability. Whether lifting heavy loads or performing delicate movements, the robot offers a glimpse into the next era of automation.
