K2 Bumblebee
Last updated:
The K2 Bumblebee is a next-generation bipedal humanoid robot from Kepler Robotics, standing 175 cm tall and weighing 75 kg, engineered for industrial applications like manufacturing, logistics, and retail. Featuring 52 degrees of freedom for human-like articulation, it boasts over 80 integrated sensors including tactile sensors in every finger, infrared binocular 3D cameras, and SLAM capabilities for real-time object recognition, gesture detection, and scene understanding. Powered by Kepler's proprietary Nebula AI platform with 100 TOPS onboard compute, it executes autonomous task sequences with millimeter-level precision using planetary roller screw actuators. Capable of 15 kg per arm payloads (30 kg dual-arm), up to 8 hours runtime on a 1-hour charge, and near-zero static power consumption, the K2 demonstrates straight-knee walking gaits for agile navigation on uneven terrain, stairs, and factory floors. Its hybrid architecture enables reinforcement learning for adaptive behaviors, making it ideal for sorti

Forerunner K2
Manufactured by Kepler Robotics
The Forerunner K2 by Kepler Robotics is a fifth-generation general-purpose humanoid robot designed for industrial and collaborative applications. Standing at 175 cm tall and weighing 75 kg, it features 52 degrees of freedom for fluid, human-like movements, including a rotating/tilting head and rigid arms/legs with planetary roller screw actuators delivering up to 8,200 N peak force. Its dexterous rope-driven hands offer 11 DOF each, with 96 tactile contact points per fingertip for precise grasping up to 15 kg per hand and 25 kg total payload. Equipped with infrared binocular 3D cameras, over 80 sensors for tension/pressure/torque, and a 100 TOPS Nebula AI system, the K2 excels in visual SLAM navigation, autonomous task execution via imitation/reinforcement learning, and real-time environmental adaptation. With 8-hour runtime on a 2.33 kWh battery, improved gait stability, and cloud integration, it supports dual-arm handling in manufacturing, logistics, inspection, and high-risk operations, enabling seamless human-robot collaboration.
