Overview
Shanghai Kepler Robotics makes the Forerunner K2, which it describes as a full-sized, general-purpose humanoid robot. It stands 1.75 m tall and weighs 75 kg. Each hand has 11 degrees of freedom and 25 force-sensing contact points per finger, and the whole body has 52 degrees of freedom, well above the database median of 29.
Kepler says the robot has begun shipping to customers. The published list price is CNY 248,000 for the Bipedal Basic configuration in China, with tax and shipping not stated; the maker gave this as a starting price across three configurations.
Power is where the figures stand out. The battery is rated at 2330 Wh and runtime at 480 minutes, against a database median of 180 minutes, and charging takes 60 minutes. Kepler also states a carry payload of 30 kg, 15 kg per hand, 100 TOPS of AI performance and a 6-axis force/torque sensor at the wrist. Developers get the Kepler Robotics Developer Platform and Kepler Studio, a drag-and-drop motion tool with natural-language input. Walking speed, processor model and safety certifications have not been published.
