The vehicle has a central controller-- STM32--and a sub-coordinate controller--Arduino MEGA 2560--that coordinates multiple sensors including an inertial sensor, ultrasonic sensors, etc. Global Navigation Satellite System (GNSS) and the inertial sensor enable the vehicle's localization. Remote ...
Using a carrier frequency of 40 kHz, the FSK ultrasonic modem presented in [59] uses a very low-cost waterproof ultrasonic transducer typically used in the automotive industry for measuring the distance from the car and the closest obstacle. All processing is performed with an Arduino, and from...
