In addition, the author puts forward an argument for properly regulating the proportion ratio of run - up speed, and enlarging the soaring angle when it s impossible to achieve the same speed as Luise s (low - jumping style) .

Following the biological structure of the leg of a kangaroo and the characteristics of its hopping,we establish the hopping model of a kangaroo robot,the kinematics and dynamics equations during its touching down on the ground,with its joints nonlinear stiffness taken into consideration.

The analytic expressions for the first three higher order harmonics of the space charge field versus time and the applied field are presented by using perturbative expanding to “the hopping model” of Feinberg.
