Kepler K2 Bumblebee vs Leju Kuavo

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

Leju Kuavo is a family of full-size biped humanoids from Leju Robotics, with base KUAVO independently tested by CTTL at 45 kg, 26 DoF, 4.6 km/h pace, and 20cm jumps; KUAVO-MY variant is 1.4 m with >40 DoF. Leju's IPO filing reports 577 Kuavo units sold in 2025 for 178 million yuan. A public torchbearer event demonstrated 100m torch carrying and handover, but was explicitly teleoperated. Several YouTube titles suggest parcel delivery, household help, modular hands, and FAW factory work, but lack transcripts. No autonomous manipulation, runtime, battery, sensor, or hand specs were found in reviewed sources
