Abstract

Unmanned Ground Vehicles are used for various reasons. One of them is used in search and rescue operations which are known as Throwable Unmanned Ground Vehicles. It is a type of Unmanned Ground Vehicle which can sustain falls from several meters. Such vehicles are easily deployable, lightweight and impact resistant. Wheels play an important role since they absorb most of the impact. To optimize the performance of such vehicle, mathematical modeling is necessary. In this research paper, the main goal is to model the system mathematically. Parameters like impact forces, elasticity, Young’s modulus and duration of impact depend highly on material properties and structure of wheels. Results show the effect of certain parameters on wheel’s design and materials. For that purpose three materials are chosen PCTPE, carbon fiber, and vulcanized rubber for wheels. Impact forces, and duration of time are plotted against height of fall and diameter of the wheel for these materials.
