This paper proposes an optimal galloping trajectory which costs low energy and guarantees the stability of the quadruped robot. In the realization of the fast galloping, the trajectory design is important. As a galloping trajectory, we propose an elliptic leg trajectory, which provides simplified locomotion to complex galloping motions of animals. However, the elliptic trajectory, as an imitation of animal galloping motion, does not guarantee stability and minimal energy consumption. We propose optimization based on the energy and stability using a genetic algorithm, which provides the robust and global solution to a multi-body, highly nonlinear dynamic system. To evaluate and verify the effectiveness of the proposed trajectory, computer simulations were carried out.

This work introduces the quadruped robot designed at Hanyang University and preliminary dynamic simulation of dynamic walk, which is called HUNTER (Hanyang UNiversity TEtrapod Robot). HUNTER has three active joints and one passive spring-loaded joint at each leg. Its design is based on the analysis of the characteristics of typical 4-legged animals in walking and running. The passive joints at the legs were designed to reduce the ground impact in landing and to be able to reuse the stored energy in the springs. The apparatus of the hardware was analyzed in FEM to reduce the weight while maintaining the strength of the structure of the robot. All the design parameters of the structure as well as actuators are selected based on dynamic simulations. In this work, the results of simulating a dynamic walk are also described.
