Kepler K2 Bumblebee vs Xiaomi CyberOne V2

Kepler K2 Bumblebee is a commercial industrial humanoid from Shanghai. It is 175 cm, 75 kg, 52 DoF, with 11-DoF hands, a hybrid roller-screw/rotary actuator design, 100 TOPS compute, and a claimed 30 kg dual-arm payload and 8-hour runtime on a one-hour charge. Kepler lists a $30,000 base price or RMB 248,000 and announced mass production and shipments in September 2025. The most concrete positive evidence is a company-described gait video showing the robot walking over bricks, plastic and grass and remaining stable under pushes. Commercial proof is limited: confirmed orders of over 47 million yuan are reported, and an official video title suggests a Zhaofeng Motor on-the-job log, but 2025 revenue was only 4.34 million yuan with heavy losses and the company was acquired at a lower valuation. Autonomy, endurance and manipulation claims are mostly company statements without independent verification; many demo videos are title-only with no teleoperation disclosure

Xiaomi CyberOne V2 is the second-generation of Xiaomi's biped humanoid, described as roughly 1.70 m tall and shown publicly at Xiaomi's April 2026 Investor Day, at the World Robot Conference in August 2026 and at IFA Berlin in September 2026. Its only quantified capability evidence is a company-reported self-tapping nut-installation task on Xiaomi's own Beijing EV assembly line: 90.2% success over a three-hour autonomous run inside a 76-second cycle, rising to about 98% after roughly four months of on-site application. Xiaomi also reports a redesigned hand at human scale with degrees of freedom in the 22–27 range, full-palm touch, 150,000-cycle durability and evaporative cooling, and has open-sourced a 4.7-billion-parameter VLA model. Nothing here is independently verified: there is no Xiaomi spec sheet, no price, no external customer, and the six videos in the source set are title-only
