China’s compact humanoid robot demonstrates human-like balance

In a recently released video, PM01 is seen dancing before being deliberately knocked off balance with several pushes and kicks, then adjusting its posture in real time and resuming movement within seconds.

It also performs a controlled front flip, coordinating arm swing, core stabilization, and landing mechanics.

Another sequence shows it lying flat on its back before smoothly rising to a standing position, using weight shifting and bracing motions similar to human movement.

PM01 stands 1.38 meters tall and weighs about 40 kilograms. It is designed for research applications that integrate human-like motion with advanced control systems.

It features a core display for interaction, a bionic structure that mimics human kinematics, and a waist capable of rotating up to 320 degrees.

According to Interesting Engineering, experts note that shorter humanoids benefit from a lower center of mass, which reduces tipping risk and lowers the rotational torque required for flips and recovery. Full-sized humanoids face greater mechanical stress during landing and therefore require more powerful actuators, reinforced joints, and stronger structural design to maintain stability.

EngineAI said on Jan. 26 it partnered with Beijing Interstellar Human Spaceflight Technology to send the world’s first humanoid robot into space using the PM01.

However, the company drew skepticism last year after releasing a video of its T800 humanoid performing physical demonstrations, including breaking doors, throwing punches, and knocking down the founder during a sparring session.
