“…The first studies on new configurations (active rocker-bogie system) were presented in [13]. A separate path of studies [14] was devoted to manipulators used in URC challenges. In this paper design and results of FEA static analysis were discussed.…”

Unmanned vehicles are often used in everyday life, mostly by rescue teams or scientists exploring new terrains. In those constructions, the suspension has constant dimensions, which leads to many disadvantages and limits the application area. The solution to these problems can be creating a six-wheeled mobile platform that can dynamically change the wheelbase in relation to the area of action or terrain inclination angle. The active change in location of the center of gravity gives a possibility to access sloppy obstacles not available with classical suspensions. The main scope of this study is to investigate the influence of material properties on vibration frequency at different lengths of suspension members. The obtained results will allow finding the optimum material for producing a prototype unit.

“…These include manipulators, special measuring devices and containers for transporting dangerous goods, radars, and scanners - [15]. This gives a challenge to the constructors in which they have to face the combination of all these components into one vehicle - [14,16,17].…”
