Short summary
An electrohydraulic servo four-legged heavy-duty (FLHD) robot has been designed and developed. An integration layout cylinder design scheme for a non-lightweight hydraulic servo four-legged robot with high loads and torque of the hip joint is proposed, and the mathematical element analysis model for a parallel-executed cylinder (PEC) system is derived. A design idea of a force–position hybrid control scheme is determined for the PEC.
