FABRICATION OF AUTOMATIC FOLLOWER TROLLEY

Abstract

Trolley is used to carry the products in industries, super markets etc. In this modern world, people uses different types of trolley. This project is developed for the users to use an automatic human follower trolley using sensors. It consists of trolley, sensors, Battery and microcontroller unit. The trolley can move forward, reverse, left and write. It will not dash on any obstacles since it uses artificial intelligence. If there is a path (Black parallel lines), the trolley will follow the path as like a human being. It has two inbuilt transmitters and receivers on the front side. The transmitter transmits signals and simultaneously the receiver receives the transmitted signal. If the trolley misses its path, it automatically moves left or right and again senses the reflected signal. Thus it can follow the path. Also there is a sensor in the front side. It senses whether the user is standing near the trolley. If the user moves, the sensor sends signal to the microcontroller and thus the microcontroller switches on the trolley motor and if the user stops, the microcontroller switches off the motor to stop the trolley.
