About

Kepler Robotics is a Shanghai-based humanoid robotics company founded in 2023, developing industrial-grade humanoid robots for manufacturing, logistics, and high-risk operations. Its flagship K2 "Bumblebee" uses a hybrid serial-parallel actuator architecture — combining roller screw linear actuators and rotary actuators — and is designed for factory floor deployment with a 30 kg dual-arm payload and 8-hour operating time. The company manufactures over 80% of its core hardware in-house. According to Kepler Robotics and The Robot Report.

Debuted its K2 "Bumblebee" humanoid at ICRA 2025.
K2 "Bumblebee" is now in small-series production / commercial rollout as of 2025.
K2 "Bumblebee" demonstrates 8-hour continuous operation on a single 1-hour charge, dual-arm 30 kg payload, 52 DOF, industrial-grade actuators — positioning it as China's first hybrid-architecture mass-produced humanoid robot.
