A comparative study on LIDAR and Ultrasonic Sensor for Obstacle Avoidance Robot Car

In this comparative research, the effectiveness of LIDAR and ultrasonic sensors two widely used sensors for obstacle avoidance in robot cars was assessed. To compare the accuracy, range, and reaction times of the two types of sensors in detecting obstacles, two obstacle avoidance system was designed and put into use. According to the findings, ultrasonic sensors are less costly and have a faster reaction time than LIDAR. LIDAR which has a higher accuracy and greater range compared to the ultrasonic sensor. However, environmental conditions like sunshine and dust might have an impact on the functioning of LIDAR sensors since they are more sensitive to them. The study concludes that the needs and limitations of the application determine the best sensor for an obstacle avoidance system in a robot automobile. LIDAR is often a good choice for applications that need high precision and a greater range, but ultrasonic sensors are better suited for applications that need quick reaction times and are price sensitive.
