Motor control is achieved using the AFMotor library, and the distance calculation is based on the sensor's pulse duration. An assistive walking stick prototype designed for visually impaired ...

The ultrasonic sensor acts like a third eye, helping to calculate the distance to objects. The Arduino keeps on processing the data from the ultrasonic sensor, and it quickly triggers the Audio alert ...

Not so, if you use a pair of specialised ultrasonic transducer arrays to move the air instead! (Video, embedded below) Three banks of thrusters provide a 180 degree steerable net force Details are ...

This project provides ROS drivers for Bosch Off-Highway sensor systems. (Radar Off-Highway Premium, Radar OHW, General Purpose Radar Off-Highway (GPR), Ultrasonic Sensor System OHW Entry & Premium) ...

With a standard old HC-SR04 ultrasonic sensor, an audio module and a servo to drive a custom gauge needle he’s made a device which can warn people around you if they’re too close for comfort.
