Skid-steered wheeled vehicles are commonly adopted in outdoor environments with the benefits of mobility and flexible structure. However, different from Ackerman turning vehicles, skid-steered do not possess geometric constraint but only dynamic when steered, which leads to motion control state estimation problems for vehicles. The controlling accuracy a vehicle depends largely on feedback info...

Tracks and wheels are the most widely used running gear for locomotion of agricultural vehicles. The main difference between two systems is contact area with ground and, consequently, pressure distribution. Evaluating distribution on important because soil damage vehicle performance depend it. This analysis especially difficult tracked vehicles, owing to their complexity compared wheeled system...
