Biped robots require massive power on each leg while walking, hopping, and running. We have developed a flow-based control system-called hydraulic direct drive system- that can achieve high output while avoiding spatial limitations. To implement the proposed system with simple equipment configuration, a pump and single-rod cylinder are connected in a closed loop. However, because compensation for ...
