Nowadays, Autonomous carrier vehicles are becoming more predominant for the modern society. Hence designing these vehicles is one of the core fields of automation engineering. In regard to that, our project full-fills an idea of autonomous transportation. This vehicle is a carrier of materials from one place to another place through a fixed lane Path (guide way). It can also act as an easy vehicle for disabled and blind people in their houses.
The main carrier consists of a table mounted on four omni-wheeled base which has control unit which guides the direction of the wheels. The carrier has an insert which moves through a guide keyway. Each junction and turning points has proximity sensor which indicates the position of carrier to the controller. The microcontroller is programmed in such a way that it can find the direction that the bot has to move at every junctions. This was programmed by considering the shortest path between the current position and the destination point. The controlled signal is amplified and made to actuate the motor control relays.
Carrier bot is operated wirelessly using RF remote which has the position buttons. Those buttons are assigned as the positions. These are the positions that the sensors were built. When we call the bot to a point by pressing the corresponding button it can arrive to that point from any positions and it can autonomously find its way to there and can be sent to any position in a similar way. It can find its applications in a variety of area so as stated as multi-purpose carrier, ranging from hypermarkets to hospitals and libraries to warehouses. In hotels and restaurants it can be employed to serve the food as a servant.
