DESCRIPTION
The K2 Bumblebee is Kepler's general-purpose bipedal humanoid robot, standing 172 cm tall and weighing 75 kg with 52 degrees of freedom under whole-body control. It combines 14 planetary roller screw linear actuators (8,000 N peak force) with 16 rotary actuators (200 Nm peak torque) and a pair of in-house 11-DoF tendon-driven dexterous hands with high-density tactile sensing. Perception runs on an infrared binocular 3D camera (Orbbec Gemini 330), a far-field 4-microphone array, and more than 80 body sensors, with computing split between an Intel i5-1145G7E motion module and an NVIDIA Jetson Orin NX (100 TOPS).
