China’s Unitree, which set a new world speed record for humanoid robots earlier this month, is now breaking another record. Its newest biped, the H1, is the first animal that can do a standing backflip without using hydraulics.

Yes, humanoids like Boston Dynamics’ Atlas have been practicing backflips for several years, but they use heavy, potentially leaky hydraulics to launch themselves into the air, flip backwards, and then land on both feet.

Impressively, Unitree’s H1 relies solely on its own M107 articulated electric motors, which each have a maximum torque of 360 Nm (265.5 lb ft) and can also be found in the company’s four-legged B2. Each leg has three degrees of freedom at the hip and one at the knee and ankle, and all cables are internally routed to ensure clean, snag-free lines.

Unitree used a reinforcement learning simulation to teach H1 the art of on-the-spot flips, and he pretty much nailed it as planned, save for a corrective mini-jump at the end.

While such a visually impressive skill is probably a must-have for your robot resume, real-world applications beyond entertaining party guests seem somewhat limited. Fortunately, H1 added more potentially useful feats to the development trophy cabinet, including fast walking, stair climbing, standing jumping, and even dancing.

The H1 is a relatively new entry into the humanoid development space, but it currently has an estimated price tag of $90,000, though it could take up to 10 years to hit the market. It is 1.8 m (71 in) long, weighs 47 kg (104 lb) and can carry up to 30 kg (66 lb). However, it currently does not have human-like arms like Tesla Optimus or Figure 01, but they are being worked on.

Although Unitree claims a world record speed of 3.3 meters per second (7.4 mph), the company expects a commercial device to reach speeds of around 5 m/s for general use. An array of sensors on the head, consisting of 3D LiDAR and Intel RealSense depth camera, allow you to scan the world around you. The specs currently list a removable 864Wh battery, but it’s still early days for this project.
