Efficient, robust, and nimble
open-source legged robot
Updated: February 11 2018
The Tik-Tok project aims to build an open-source biped robot platform with the dynamic balance and robustness of Boston Dynamics's New ATLAS robot, but at a tenth the cost and energy use. Think of it as a "Segway with legs."
Its Cost of Transport (CoT) in simulation is 0.25 (≈ human). Tik-Tok uses high-efficiency chain drives and powerful brushless motors to create a highly nimble robot platform. If pushed or tripped, it can reposition its foot by up to a full step in under a quarter of a second (also ≈ human). Tik-Tok is 1.5 m tall (with head, as shown), weighs 30 kg, has 12 actuated joints, has a peak joint power of 2 kW, and is expected to be able to walk about 15 km on a single charge of its 300 W-hr 2 kg battery.
