Abstract
Our project has four features. It is initiated via a Bluetooth controller. Operator fixes the designated checkpoint. It can be controlled both manually and can run autonomously. Then vehicle runs on distinguishing the black path with the white space around via 4 IR sensors attached ahead of the vehicle. There is ultrasonic sonar that detects any obstacle in front on the following path. Sonar stops the vehicle keeping a distance of 15 cm away from that obstacle. This vehicle is set up algorithmically to take the rightmost path when any obstacle comes over its black line path. Our project is made to carry an approximately 10kg weight and reach to the designated checkpoint targeted by operator via Bluetooth. It has no limitation for unloading. The main unique feature is that it can take a rotation of 360 degree when task is completed after unloading. Vehicle comes back to the original point from where it has been started after 360 degree rotation from the end point. It is designed with 4 customized wheels connected with 4 Dc gear motor at four different corners under a PVC board. Over the board there is motor shield connected in parallel with Arduino mega. Ultrasonic sonar and 5 IR sensors and 12 volt battery are connected with Arduino too.
