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.

K2 Bumblebee is a humanoid robot built by Kepler Robotics.

Supply chain

No verified supply relationships on file. Supply-chain coverage is being added across the registry; check back as the seed populates this model’s suppliers.

Suppliers appear here when verified with at least two strong sources (maker-official / IR / regulatory / standards-body / verified tier-2). Sources are append-only; corrections add new sources rather than rewrite history.

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.
