Kepler K2 Bumblebee
175 cm, 75 kg factory biped sold in China from CNY 248,000; one named plant test, company-reported.
The K2 Bumblebee is a full-size industrial biped (about 175 cm, 75 kg, 52 DoF, 8 hours claimed runtime) with a hybrid actuator architecture. Kepler announced mass production on 2025-09-26 at about CNY 248,000 (about USD 34,000), with framework agreements for several thousand units. The only named user is a SAIC-GM plant in Shanghai where two K2 units were filmed in April 2025, which is company-sourced.
Our verdict
Serious hardware and an aggressive price, but no independent evidence of customers or delivered volumes; now majority-controlled by a listed component maker.
