About the Forerunner K2 (Bumblebee)
Designed for manufacturing, logistics, warehousing, inspection, and industrial automation, K2 introduced Kepler's hybrid actuator architecture combining planetary roller-screw linear actuators with rotary actuators. It is widely regarded as one of the first humanoids designed specifically for large-scale commercial deployment rather than research demonstrations.
Typical applications: Manufacturing & Industrial Operations, Research & Development, Education & Training.
