In this project we will use such a mechanism which can simultaneously allow switching over track and a wheel. The outcomes of simple track shows that it is better for off road but when it comes to a plane surface it reduces the efficiency and damages the surface but under this project we are worked on such a wheel which can play a simultaneous role of a wheel and a track with the essential features of both wheel and track. Key words: Galileo Wheel, Track, Wheel Lead Screw. 1. INTRODUCTION: Galileo wheel is a modified version for Continuous track, also called Tank tread or Caterpillar track, is a system of vehicle propulsion in which a continuous band of treads is driven by two or more wheels. This band is typically made of modular steel plates in the case of military vehicles, or rubber reinforced with steel wires in the case of lighter agricultural or construction vehicles. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tires on an equivalent vehicle,
