The main goal of this project is to create four robotic systems that can carry a flag in hurdle area. The basic working principle of these systems is to detect robots and obstacles at a certain height with a camera located out of the platform and to establish routes by color selection. With the routes calculated, we will establish a map for carrying the flag to another robot. The technical process of the Project is mainly based on the Image Processing, Embedded stems, Robotics, artificial Intelligence and Control Systems. TECHNICAL SPECIFICATIONS
There are 4 important parts for this project. These are : 1. Brain Module 2. Communication Module 3. Movement Module 4. Flag Changing Module Generally, Python was used for coding RaspberryPi 3B+ and OrangePi Zero BRAIN MODULE Robot localization(finding location and direction) with object detection by using color filtering and contour detection Smooth path planning with A* search algorithm by using custom Heuristic function COMMUNICATION MODULE Reliable data and message transfer using TCP packets Responsible for communicating with the brain(Raspberry Pi) and the controller. MOVEMENT MODULE Path tracking with remotely operated PID controller Modelling the robot and simulating the PID controller Movement simulation with using mathematical model of the Differential Drive robot. FLAG CHANCING MODULE Used a metal plate as a flag. Changing the flag by using electromagnetic module CONCLUSION In this project, we designed 4 robotics which can carry a metal plate to each other autonomously by using Python PYTHON – RASPBERRY PI – ORANGE PI Used Python programming interface to program our controllers. Used OpenCV for image processing. Implemented the code for A* algorithm and PID controller for movement module. Used RaspberryPi for our Brain module. Used OrangePi Zero for our Movement module.
