A chassis is the load-bearing framework of an artificial object, which structurally supports the object in its construction and function. A chassis is one of the most important components of a vehicle it is ideal for RC cars and robots., without which the car would have no structure. It is the backbone of the vehicle on which the total load of the vehicle is applied. The components of the vehicle like a power plant, transmission system, Axils, wheels, electrical system are mounted on the chassis. It is the main mounting for all the components including the body so it is called a carrying unit of the vehicle.
