Online Jumping Motion Generation via Model Predictive Control
Autor: DongHyun Ahn, Baek-Kyu Cho
Publikováno v: IEEE Transactions on Industrial Electronics. 69:4957-4965
Legged robots can move on various grounds via walking; however, they have difficulty in moving fast. To overcome this limitation, some legged robots have been studying dynamic motions such as jumping and running. In this paper, we present a strategy

Optimal Standing Jump Trajectory Generation for Biped Robots
Autor: Baek-Kyu Cho, DongHyun Ahn
Publikováno v: International Journal of Precision Engineering and Manufacturing. 21:1459-1467
One of the disadvantages of biped robots is the slow movement. Jumping or running can be the solution to this. This paper describes an optimal jump trajectory generation method for biped robots. In order to conveniently create a jumping trajectory, t
