Motion modeling in physics involves determining the physical parameters of motion related to the change in the position of a point or rigid body over time described in reference system. This results in physical motion parameters, including disturbances such as wheels slipping on the ground as an effect of atmospheric changes or material property. On the basis of the theoretical model of dynamics of motion presented in the authors' previous works, in this paper the results of numerical and experimental studies of the motion of a four-wheeled mobile platform has been presented. The tests have been carried out on the basis of plane motion, taking into account the occurrence of wheel slippage. Numerical tests have been performed using an original computational algorithm that was used to obtain motion parameter data. Selected cases have been described in the work and compared with experimental tests showing the physical parameters of actual motion of the robot. The experimental research included test runs during which slippage was observed in the form of a deviation of the trajectory from the straight line of motion. Identification of the physical parameters of the robot's motion and their comparison included the analysis of distance and velocity as a function of time. Both the nature of the results in graphical form and the values of selected test runs with the corresponding motion simulations have been verified. The results are included in the work. The conclusions are included in the last chapter of the work.
