Obstacle Avoidance Robot Circuit Design Solution

The robot control board contains an atmega328p microcontroller and an l293d motor driver. It is not different from the Arduino Uno board, but it is more useful because it does not require another shield to drive the motors! It is not affected by jumper interference and can be easily programmed with the CH340G. Different sensors can also be controlled by using the I/O pins on this board while driving two DC motors. The robot has four modes, namely sumo mode: this is a sport in which two robots try to push each other out of a circle (similar to the sport of sumo wrestling); follow mode: it can sense the presence of an object to follow using the HC-SR04 sensor; tracking mode: the follower robot is a vehicle that follows the black or white line; avoidance mode: the obstacle avoidance robot is an intelligent device that can automatically sense the obstacles in front of it and avoid them by turning itself in another direction.
