An Internet of Thing based Obstacle Avoidance Robotic Vehicle Using Ultrasonic Sensor and Arduino

Our work describes an obstacle avoidance spider robot vehicle which is controlled by ultrasonic sensor. The robot was manufactured and printed using a 3D printer and using an ultrasonic sensor controlled by an Arduino microcontroller. We used ESB-32 CAM board, which contained a set of sensors are Wifi, Bluetooth, Camera which shows robot movement with the flash and its IP is 192.168.1.132, RAM memory and Antenna. Ultrasonic sensor fixed in the front portion of the robot vehicle. The sensor gets the data from surrounding areas through mounted sensors on the robot. The sensor is sensing the obstacle and deviate its path to choose an obstacle free path. The sensor will be sending the data to the controller is compared with controller to decide the movement of the robot, our vehicle robot can compute the distance to the obstacle until 100m. We use the spider as a type of robot. The spider robot movement and direction will be based on the sensing of the ultrasonic sensor and also using a spider encoder. This robotic vehicle is used for detecting obstacle and avoiding the collision. We have programmed the controller to be used by Arduino application and used the Bluetooth for controlling the movement of the robot. Our work used the Internet of Things (IOT), where a network was formed that was understandable to all its components through the language of communication known to elements of this network.
