The paper describes the indirect method of obtaining the information on wheel pair skidding. The method is based on using a special filtration scheme which filters the estimated resistive torque and highlights the signal which is proportional to wheel pair skidding. The work introduces as well the imitation modeling results. https://www.roneverhart.com/Traditional-Karate-Do-Okinawa-Goju-Ryu-Book-1-The-Fundamental-Techniques-by-Morio-Higaonna-Preowned/
