## Common questions

### What is K2 Bumblebee?

Kepler Robotics (legally Shanghai Kepler Exploration Robot; founded 2023 in Pudong, Shanghai; CEO Hu Debo) makes the K2 Bumblebee, a fifth-generation full-size industrial humanoid notable for its proprietary planetary roller-screw linear actuators and a straight-knee hybrid gait. Verified specs include 175 cm, 75 kg, 52 degrees of freedom, 80-plus sensors, 100 TOPS of onboard compute, about 15 kg of payload per arm, and roughly eight hours of runtime, at a list price of RMB 248,000 (about $34,000). It was shown independently at ICRA 2025, and units entered real-world testing at an SAIC-GM auto plant in Shanghai for quality checks and material-bin transport, corroborated across multiple outlets; the company is now reportedly controlled by the A-share-listed Tao Motor via acquisition. The registry records it at pilot maturity rather than commercial: Kepler's own 'world's first commercially available' and 'mass production' framing names zero end customers and quantifies demand only as framework agreements for several thousand units, which is a claim rather than booked orders. The strongest verifiable signal is the SAIC-GM plant testing, not a commercial supply contract, so volume shipments, the unnamed framework agreements, and a secondary-blog wheel-hub deployment are recorded as claimed-but-not-verified.

### Who makes K2 Bumblebee?

K2 Bumblebee is made by Kepler Robotics, based in Shanghai, China, founded in 2023.

### Where is K2 Bumblebee deployed?

No verified deployments of K2 Bumblebee are currently on the DEPLOY registry. DEPLOY records deployments only when verified at a named site with a primary source; absence may reflect pre-deployment, research, or manufacturer-internal use.

### What is K2 Bumblebee's maturity stage?

K2 Bumblebee is at the pilot stage on the DEPLOY maturity ladder (research, prototype, pilot, commercial, production). Pilot stage means at least one named-customer trial deployment is verified.
