Abstract
A parallel-series connection walking robot and a construction method thereof. The parallel-series connection walking robot mainly comprises leg mechanisms A and B; one leg mechanism A is a parallel-series connection leg mechanism (); the other leg mechanism B is a parallel-series connection leg mechanism () or a foot parallel-connection mechanism (); and the parallel-series connection leg mechanism () is formed of a thigh mechanism () and a foot parallel-connection mechanism () through serial connection. The two leg mechanisms have a combination of a specific DOF; upper portions of the two leg mechanisms are fixedly connected together; all members are comprised by and intersected with each other, but have independent activity spaces, respectively; and projections of the triangles formed by toes of the two leg mechanisms on a horizontal plane overlap with each other. During an advancing process, the robot can stably walk in any direction without left-right gravity center adjustment; and the robot also has the advantages of less kinematic pairs, lower robot body height, strong bearing capacity, steering flexibility, strong obstacle crossing ability and climbing up and down ability.
