Abstract

An object following robot is a robot that can follow a target object relentlessly when it has succeeded detecting the object. When the object moves, it follows the object and when the object stop, it stops. In most of the current implementations, the security cameras used in monitoring traffic, industrial process controlling, and crime detection are mounted at a fixed position. This way allows them to capture only the images of objects within their 360o movement which limits the monitoring area. Thus, the purpose of this project is to develop an object following robot that tracks a target object and follows it using colour-based and contour-based methods. To be specific, this project considers a ball as the target object. This following robot consists of three main components which are microcontroller, camera and DC motors. The project uses Raspberry Pi for image processing and it also acts as microcontroller to control the movement of the robot. A camera is attached to the raspberry pi to capture the object. Besides, two DC motor are used to allow the movement of the robot. In addition, a monitor display which is a smartphone is used for displays the object that is captured by the camera. The result of this project is analysed to identify the performance of the object following robot. The results show that the accuracy of the colour tracking by using colour-based method is 87.3% and the accuracy of the robot goes forward to target object is 90% while the accuracy of the robot turns left, and right are 86%.
