Smart Shopping Trolley Robot

Robotics technology has advanced significantly in the lastfew years. Robots that can identify and follow humans are necessary to support them in their work; thus, devices that can communicate and coexist with humans—such as the “RFID based Human Following Load carrier”—must be developed. One of the main challenges in enabling the robot to do various tasks in the actual world is localizing both the robot and the objects in its environment. To track a person incrowded areas, in an indoor and outdoor environment, and through traffic, a robot must possess advanced navigational skills. The project’s objective is to construct a following robot that can carry objects beside people. Airports, shopping centers, construction sites, and agriculture can all make use of it. The gadget that controls the entire system is a microcontroller. RFID readers can identify items by using the RF signal that the object transmits. The identification and location of items are aided by sensors like infrared andultrasonic sensors. DC motors and an RFID module are attached to the microcontroller. To do this, a programme written in the Embedded ‘C’ language is loaded onto the controller.
