Automatic Human Following Trolley using Raspberry pi

This paper represents the human following trolley using a raspberry pi. Our project focuses on developing an intelligent trolley that possesses the ability to autonomously navigate and evade obstacles, while also establishing interaction and communication with a designated individual. The primary objective is to design and construct a robot that not only tracks the target person but also advances towards them, taking care to avoid any obstacles encountered during the tracking process. To streamline this operation, we have incorporated a unique tag system, which is affixed to the person to be followed by the trolley. A compact Raspberry Pi camera continuously captures images of the distinct tag, comparing them to the original reference image. Upon successful matching, the trolley proceeds further, while simultaneously utilizing ultrasonic sensors to circumvent any obstacles in its path. The tag serves as a crucial element in ensuring uniqueness and simplifying the overall task. The mechanical structure of the trolley has been thoughtfully designed, and electrical components are employed to enable its functionality. All computational processing is carried out using a Raspberry Pi platform.
