Although the navigation for blind using ultrasonic is a complex process but here we will present only the hurdle detection procedure. The project make the use of UNO Arduino processor, ultrasonic ...

Circuit Diagram . Arduino UNO, motor driver, ultrasonic sensor, gear motor, servo motor, 9v battery, wheels, jumper wires all these hardware are connected with each other. Also check other obstacle ...

About the hardware part: has been used an Arduino Uno as board, a Sensor Shield v5.0 and an L298N Dual Bridge, both optional, used to manage cables of wheels. A servo motor to rotate the ultrasonic ...

Obstacle detection using three ultrasonic sensors placed at the front and sides of the robot car. Automatic mode for obstacle avoidance based on sensor readings. Manual mode for direct control of the ...

This paper presents both simple and complex obstacle detection using an ultrasonic sensor ring with overlapped beam pattern. It is assumed that a set of ultrasonic sensors of the same type are ...

Sonair’s 3D ultrasonic sensor uses acoustic detection and ranging (ADAR) to enable 360° obstacle detection up to 5 meters. Each ADAR sensor offers a 180×180° field of view, allowing autonomous mobile ...

Here an Ultrasonic sensor is used to sense the obstacles in the path by calculating the distance between the robot and obstacle. If robot finds any obstacle it changes the direction and continue ...
