As part of my internship at IIIT-B which I started in January 2023, I have been working on an Arduino Uno R3 based Two Wheeled Robot. My project involves multiple such robots interacting with each other as well as the environment. I am currently using the Arduino IDE for this project. The robot was fully assembled with an Ultrasonic sensor HC-SR04, DC Motors and L293D motor driver, and programmed for obstacle avoidance. The kit came with an HC-05 Bluetooth UART Module for establishing communication for simple indoor applications. When I started testing it for other functionalities, I realised that retrieving the original obstacle avoidance code was not possible and hence contacted the provider for the original code and libraries required for the same. The code I received was not giving me any results, and hence I went ahead and simply installed the standard Adafruit Motor Shield library. I have used the examples from this library to programme locomotion of the robot. Currently, the robot can maintain a fixed distance from any obstacle, it moves back if the obstacle is too close and keeps moving forward if there is no obstacle within the fixed distance range. I have also finished establishing the robots as Master and Slave using the HC-05 Bluetooth UART module. This communication link will be used to coordinate and ensure synchronisation between the bots.
