SUMMARY:

 

K2 Bumblebee is a 175 cm, 75 kg fifth‑generation humanoid robot developed by Kepler Robotics. It features 52 degrees of freedom, planetary roller‑screw linear actuators, 11‑DOF dexterous hands with 96 tactile sensors per fingertip, 30 kg dual‑arm payload, 100 TOPS onboard compute, and 8‑hour operation from a 1‑hour charge. It is available in Bipedal Basic, Bipedal Developer, and Wheeled Developer configurations.  

 

EDITORIAL:

 

K2 Bumblebee is one of the most advanced mass‑produced humanoids in China and a major milestone in the global shift toward hybrid‑architecture robots. Kepler’s use of planetary roller‑screw actuators — normally found in aerospace and high‑precision industrial systems — gives Bumblebee:

 

- High torque density  

- High efficiency  

- Long actuator lifespan  

- Smooth, human‑like straight‑knee gait

 

The robot’s 11‑DOF tactile hands are among the most sensor‑dense in the commercial humanoid market, enabling fine manipulation tasks that most industrial humanoids cannot perform.

 

K2 Bumblebee is not a research prototype — it is a commercially available, mass‑production humanoid, already deployed in manufacturing, logistics, and inspection environments.
