The article presents the characteristics of the structure of the dependent suspension system of the Scor-pio X high-mobility vehicle, constructed for the purpose of participating in the competition of Mars rovers of the Rover Challenge series. The basic regulatory requirements of the competition and the concept of the vehicle suspension were presented and discussed. The analyzes were limited to selected vehicle motion conditions, i.e. negotiating a single terrain obstacle. The kinematic ratio in the adopted suspension system was determined and the values of forces that affect the suspension elements were analyzed. The deformation values of the suspension elements and the vehicle frame were calculated. The conclusions from the use of the vehicle and the required changes to be made to the next version of the vehicle were also presented.
