The invention discloses a quadruped robot based on a single-degree-of-freedom closed chain connecting rod mechanism. The robot comprises a robot body and mechanical legs, each mechanical leg comprises a front leg mechanism, a rear leg mechanism and a connecting plate, and the front leg mechanisms and the rear leg mechanisms are installed on the robot body in a mirror image mode. The front leg mechanism comprises a right front leg mechanism and a left front leg mechanism, the rear leg mechanism comprises a right rear leg mechanism and a left rear leg mechanism, and the left leg mechanism and the right leg mechanism are symmetrically arranged on the two sides of the machine body. The leg mechanism comprises a single-degree-of-freedom closed-chain connecting rod mechanism, a supporting plate and the like which are obtained through optimization of a closed-chain connecting rod mechanism synthesis and optimization method, the length of each rod piece of the single-degree-of-freedom closed-chain connecting rod mechanism has a fixed proportional relation, and under the condition that a motor is unidirectionally and uniformly arranged, the leg mechanism is fixed to the supporting plate. The foot end track of a single foot of the robot is an oval track, and the soaring phase and the grounding phase use the same time. The quadruped robot based on the single-degree-of-freedom connecting rod mechanism is good in walking stability and high in energy efficiency.
