The main structure uses the design of the ellipse trochoid of the 4 bar strider. We made the ellipse trochoid to be the optimum state for reaching the simulation effect when people are running. Besides, the design can switch to be a new six-bar strider. It uses a link bar to bind the axis pillar and the pedal also made the pedal slide free to reach the sport effect.

In this paper, a region approximation idea that means using a "fat curve" with a width to approximate the offset curve is proposed, and a complete set of algorithms to approximate offset curve using disk Bézier curve are given and implemented. In the algorithms, the optimal and uniform approximate curve of the offset curve as the central curve of the Disk Bézier curve is found by using Remez method, and then the upper optimal and uniform approximation principle is proposed to compute the error radius function of the Disk Bézier curve. Thus, the whole Disk Bézier curve can be obtained. In the end of this paper, the approximate effect of the Disk Bézier curve is not only analyzed and assessed, but also some specific examples are provided.
