class  WheelSlip
 A system that updates wheel slip parameters based on linear wheel spin velocity (radius * spin rate). It currently assumes that the fdir1 friction parameter is set parallel to the joint axis (often [0 0 1]) and that the link origin is on the joint axis. The slip parameter is a Force-Dependent Slip (slip1, slip2) and it has units of velocity / force (m / s / N), similar to the inverse of a viscous damping coefficient. The slip_compliance parameters specified in this plugin are unitless, representing the lateral or longitudinal slip ratio (see https://en.wikipedia.org/wiki/Slip_(vehicle_dynamics) ) to tangential force ratio (tangential / normal force). Note that the maximum force ratio is the friction coefficient. At each time step, these compliances are multiplied by the linear wheel spin velocity and divided by the wheel_normal_force parameter specified below in order to match the units of the slip parameters.
