Abstract

A novel planar six-bar bionic leg is proposed in this paper. The motion equation of this bionic leg is derived fast and conveniently according to the modeling of Assur group and then the trajectory of the foot point of the bionic leg is obtained. Compared with Theo Jansen linkage, the motion characteristics of this leg are evaluated from two aspects: step length and step height of the foot point trajectory. The results show that this novel planar six-bar bionic mechanism still has good motion characteristics under the condition of fewer linkages. Finally, a prototype of an eight-legged bionic walking vehicle is designed.
