This is a research record, not a curated recommendation.
The main field guide selects 14 companion robots for deeper review. This entry belongs to a separate 53-record index that also covers industrial, research, and developer systems.
Research summary
What the record says.
The K2 Bumblebee is Kepler Robotics' fifth-generation Forerunner humanoid, positioned aggressively on price: figures around $30,000 (about 248,000 yuan) circulate for a full-size industrial biped using Kepler's hybrid actuation of planetary roller screws and rotary units, an architecture the company compares to Tesla's approach.
Kepler announced mass production around September 2025, claiming the first commercially available hybrid-architecture humanoid, with shipping evidenced by company videos and framework agreements reportedly worth hundreds of millions of yuan, including deployment partnerships with Ant Group. Independent delivery audits do not exist, and 2026 has been quiet on dated K2 news.
K2 targets the same work as UBTech's Walker S2 at a fraction of the whispered price, which, if real, matters for the entire cost curve of humanoid labor.
