It is considerable the number of research around the subject of motorization of conventional manual wheechairs, however the found models don't take care of the real necessities of the wheelchair users. In the manufacture the necessity of an independent vehicle for the load transport exists. With the increasing necessity in Brazil to develop the knowledge in the area of independent vehicles and not being still available a towboat of tests adjusted to approach such problems. The articulated towboat is an intelligent independent vehicle to tow loads. The users of conventional manual wheelchairs will go to use this vehicle when to need motorization, that is in ascent cases, descending of ramps, or long distances. This vehicle possesss practical applications that they can assist systems of support to the rehabilitation of physical and motor deficiencies and also systems automatized of manufacture. The purpose of this paper is to develop some important contribution in the area of independent vehicles in the aid for the people with special needs.
