Record-breaking: humanoid Unitree G1 robot jumps 1.4 m from a standing start
Unitree has taught its small humanoid robot G1 to jump. From a standing start, it reaches a distance that exceeds its height.

The humanoid robot G1 from the Chinese robotics company Unitree has achieved a record-breaking jump. The robot, which is only 1.32 m tall, managed to jump 1.4 m from a standing start. According to Unitree, this is the longest jump ever made by a two-legged humanoid robot of this size.
It is not easy to catapult a two-legged, electrically powered G1 robot weighing over 35 kg, depending on the equipment variant, 1.4 m. This is mainly made possible by the actuators used in the legs. Unitree uses servomotors that generate a maximum torque of 120 Nm in the Edu version and, according to the company, have a high response time and positioning speed. However, Unitree is reluctant to reveal the details of its actuators and leaves it at these basic specifications. Apparently, the robotics company does not want to reveal too much about the technology of the motors, which have been specially developed for their intended use.

Interaction of the components for a long jump
Added to this is the robot's high degree of mobility, with up to 43 degrees of freedom. The legs each have six degrees of freedom. However, the decisive factor in a jump is the interaction of all the moving parts of the body and their coordination via an AI-trained control system. For example, the G1 gains momentum with its arms and squats down in order to optimally develop its strength and achieve a greater jumping distance. The posture of the upper body also plays a decisive role, just like in a jumping person.
The Unitree G1 is extremely flexible. It can fold itself into a package measuring 69 cm x 45 cm x 30 cm. On foot, it reaches a maximum speed of 4.47 km/h. Its replaceable 9000 mAh battery is sufficient for a maximum operating time of two hours.

Unitree is currently preparing a version of the G1 adapted for mass production in order to mass-produce the humanoid robot. It is intended to be used for simple assembly work or in the household, as it cannot perform heavy work. The robot can only lift weights of up to 2 kg.
The price of the robot is comparatively moderate. It will be available from 16,000 US dollars for the standard version. Unitree is not currently stating the price for the Edu version, which has hands with movable fingers and offers slightly more freedom of movement, for example in the hips.
