On the basis of introduction of kinematic analysis methods, the paper founds the stationary coordinate system and the wheel coordinate system respectively. Meanwhile, the kinematic constraint equations of the standard centered orientable wheel is founded on the assumption that there is no slippage in normal direction and pure rolling in tangential direction of the wheels.

Luneberg lens is a spherical lens which its permittivity varies with normalized radial coordinates. It is fabricated by using different homogeneous dielectric centrically layered media. The lens can focus a parallel beam of rays from any direction exactly at a point on the surface. If it is made by adding a reflecting surface "metallic cap", it is called Luneberg lens reflector. It can reflect incident wave into plane wave in incoming direction. It is usually applied in antenna, radar reflector,satellite-based, and mobile-communucation.
