Overview
The Kepler K2, marketed as the Forerunner K2 "Bumblebee," is a general-purpose humanoid robot from Shanghai Kepler Robotics. It is designed for real-world industrial and commercial environments, targeting tasks such as materials handling, logistics, sample processing, and quality inspection. The company developed it in collaboration with a large pool of target customers and validated it through trials in actual customer settings.
The robot is built around a hybrid actuation architecture that combines planetary roller screws with high-torque rotary actuators, and it features dexterous, sensor-equipped hands for manipulation. Kepler emphasizes energy efficiency and extended operating time so the platform can sustain long industrial shifts.
Kepler has moved the K2 from customer testing into mass production, describing it as a commercially available hybrid-architecture humanoid that has begun shipping to customers, with framework agreements covering large unit volumes.

Record changelog
- Weight: 85 kg → 75 kg · Jul 8, 2026
tranche-4 verification (corrected): K1-GENERATION BLEED: 85 kg is the first-gen Forerunner (K1) weight. Kepler's WAIC 2025 PR states K2 Bumblebee weighs 75 kg (165 lb).
- Height: 178 cm → 175 cm · Jul 8, 2026
tranche-4 verification (corrected): K1-GENERATION BLEED: 178 cm is the Nov-2023 first-gen Forerunner (K1) height — the same contamination that got the published 'kepler' record excluded in tranche-3.
