1X EVE vs Kepler K2 Bumblebee

1X EVE is a wheeled humanoid from 1X Technologies (Norway/US) with a self-balancing wheeled base, 188 cm, 87 kg, 15 kg payload, 4 m/s top speed, and 6-hour official runtime. It is designed for security, logistics, and embodied AI data collection, with 25 DoF, 1-DoF grippers, HDR cameras, and shared autonomy. The strongest evidence is an Inverse-reported 2024 multi-robot voice-command office-tidying demo and directory claims of unnamed customer deployments since 2022; the weakest areas are no named customer metrics, no price, conflicting specs, and no independent autonomy verification. EVE is older than 1X's NEO and current availability is unclear

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
