Kepler K2 Bumblebee vs Unitree H1

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

The Unitree H1 is a full-size bipedal humanoid (about 180 cm, about 47 kg, 18 DoF by Unitree's per-limb counts, 864 Wh swappable battery) sold mainly to research labs through quote-based sales: Unitree's store shows a $90,000 'contact us' anchor and a European distributor lists it from EUR 93,496 excluding VAT. Its strongest public evidence is locomotion and spectacle, including a company-claimed 3.3 m/s record, 1500 m and 400 m golds at the 2025 World Humanoid Robot Games (6:34.40 and 1:28.03) and a second source crediting four track golds, a choreographed 16-robot national broadcast performance, and a company-claimed 10.1 m/s peak from a modified ~62 kg unit. Manipulation is weak: the stock robot ships without hands and with 4-DoF arms, and the manipulation literature (Stanford HumanPlus, CMU H2O) used heavily modified units. Unitree publishes no payload, runtime, failure-rate or deployment metrics; autonomy is asserted for walking and running only; third-party runtime figures conflict (1 h versus 2 h) and no independent benchmark or safety certification exists
