Summary:

 

Phybot C1 is a miniature humanoid robot created by Beijing Phybot Technology Co., Ltd., unveiled in 2025 as a research and testing platform. Unlike its larger sibling PHYBOT M1 (famous for its airborne backflip), the C1 focuses on precision, modularity, and actuator design. It integrates 25 degrees of freedom, powered by cycloidal gear actuators, making it ideal for testing embodied AI algorithms in a smaller, safer, and more controllable form factor.  

 

Editorial:

 

Phybot describes its mission as “bringing AI into the physical world”, and the C1 humanoid embodies this philosophy at a smaller scale. By using cycloidal gear actuators, the robot achieves smooth torque transmission, reduced backlash, and high durability, which are critical for humanoid locomotion and manipulation.  

 

The C1 is intended for laboratory environments, where researchers can experiment with balance recovery, gait optimization, and dexterous manipulation without the risks or costs of full-sized humanoids. It also serves as a training platform for embodied AI, allowing Phybot to refine control systems before scaling them up to larger robots like the M1.
