Overview
Kepler showed its Forerunner K1 at CES 2024 and put the K2 "Bumblebee" into mass production in September 2025. It uses a hybrid of planetary-roller-screw linear actuators and rotary joints and claims about 8 hours of work per charge. Framework agreements cover several thousand units, mostly for Chinese factories.
