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 listed at $34,000 on the DEPLOY registry. This is an actual sale price on record.

Yes. K2 Bumblebee is independently verified in real-world operation on the DEPLOY registry, confirmed at named deployment sites with primary sources: not a concept, render, or demo-only.

Not verified as fully autonomous. K2 Bumblebee's capabilities on the DEPLOY registry are recorded as teleoperated-assisted, demonstrated-only, or vendor claims (Picks and packs), not independently confirmed to run without a human in the loop.

K2 Bumblebee's recorded specifications on the DEPLOY registry: Degrees of freedom: 52; Height: 175; Weight: 75; Payload: 15. See the Specs section for the full sourced set.

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

1 verified deployment of K2 Bumblebee is on the DEPLOY registry, including at Shanghai, China.

K2 Bumblebee is available for purchase - a real sale price is on record (see the pricing section for the figure and its source).

On the DEPLOY registry, comparable humanoid robots to K2 Bumblebee include Walker S2, Digit, Unitree G1, Atlas.

K2 Bumblebee and Walker S2 (UBTech Robotics · 18 deployments) are both humanoid robots on the DEPLOY registry. K2 Bumblebee has 1 verified deployment on record. Compare both records for specs, safety, deployments, and verified-vs-claimed autonomy.

On DEPLOY's intelligence score, which blends verified deployments, safety, adoption, media, and IP signals, K2 Bumblebee ranks in roughly the top 62% of humanoid models tracked by the registry.

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.

K2 Bumblebee has no incidents on record in the DEPLOY registry. This does not constitute a safety guarantee; it reflects the incidents DEPLOY has tracked and verified to date.
