Abstract
Abstract: In most circumstances, mobile robots are stated to be autonomous, with collision avoidance being a crucial aspect of designing an autonomous mobile robot. The goal of this paper is to create a simple autonomous real-time collision-avoidance mobile robot that moves to utilise ultrasonic sensors and infrared modules. In this paper, a collision-avoidance mobile robot is designed with built-in intelligence that guides itself whenever an impediment is in its way and manoeuvre around them without any collision. This robotic vehicle is built with an AT Mega 328 microcontroller. An ultrasonic sensor detects any obstacles ahead of it and on either side of the robot, there are two infrared (IR) modules integrates to detect the obstructions and transmit an instruction to the microcontroller. The error generation is decreased with the help of the Kalman filter. Based on the input signal from different sensor integrated in the robot the microcontroller instructs to travel in a various direction by actuating the motors connected to it via a motor driver. Keywords: Mobile robot, autonomous robot, collision avoidance, surveillance, accuracy
