The full version has 52 DoF: 6 per leg, 7 per arm and 11 per dexterous hand. The basic version has 30 DoF, and a wheeled development version weighs 135 kg. The earlier K1 was 178 cm, 85 kg and 40 DoF.","K2 mixes several in-house KEPLERGEAR actuator types: planetary roller-screw actuators (up to 8,200 N peak, 81.3% energy-conversion efficiency), rotary actuators with up to 220 Nm and 0.01° repeatability, and micro actuators in the hands. Each finger has 25 tactile points and each wrist a six-axis force sensor. Kepler also shows a newer tendon-driven hand with steel cables.","Perception is vision-only, plus inertial sensors and flexible tactile sensors. Kepler quotes 8 hours of runtime and a one-hour charge. Compute is 100 TOPS on the development versions (another part of the site lists 275 TOPS for K2)."]},{"h":"Software and AI","p":["Kepler uses a hierarchical AI system that splits tasks into perception, decision and actuation layers, moving across generations from rules to data-driven models to an end-to-end large model. The robot runs Kepler's Nebula system (Kepler OS) with visual programming, multi-robot coordination, remote debugging and OTA updates. Training data comes from real-world tests, the lab, partner sites and simulation."]},{"h":"Use cases and availability","p":["Kepler lists smart manufacturing (inspection and assembly), warehousing and logistics (material handling), specialised outdoor work in harsh conditions, and research and education. It does not name customers or deployment numbers.","Kepler Exploration Robotics, which brought its first humanoid to market in 2023, is based in the Zhangjiang park in Shanghai's Pudong district. The site has a \"Buy Now\" button but no price; the configuration table gives a 90-day lead time and an 8- or 12-month warranty depending on version, and industrial versions are configured individually."]}],"timeline":[["2023","Kepler Exploration Robotics brings its first Forerunner humanoid to market."]],"faq":[["How much does the Kepler K2 cost?","Kepler does not publish a price; quotes come from sales, with about a 90-day lead time."],["How much can the Kepler K2 carry?","25-30 kg with both arms, according to Kepler."],["How long does the K2 battery last?","Up to 8 hours, with about a one-hour charge."],["How many degrees of freedom does the K2 have?","52 in the full version (11 per hand); the basic version has 30."]],"sources":[{"title":"KEPLERBOT Forerunner K2 product page","publisher":"Kepler Exploration Robotics","url":"https://www.gotokepler.com/productDetailK2","date":"2026-10"},{"title":"KEPLERBOT Forerunner K1 product page","publisher":"Kepler Exploration Robotics","url":"https://www.gotokepler.com/productDetailK1","date":"2026-10"},{"title":"About Kepler and contact (site texts, English locale)","publisher":"Kepler Exploration Robotics","url":"https://www.gotokepler.com/about","date":"2026-10"}],"updated":"2026-10-10"},"mera":{"rental_with_operator":false,"sale_in_offer":false,"availability":"confirmation_required","shop_url":null},"url":"https://merarobotics.com/blog/humanoids/kepler-k2","inquiry_url":"https://merarobotics.com/en/start?service=purchase&robot=kepler-k2"}
