Vehicle that Navigates by Audio

This project involves navigating a vehicle through a minefield by using audio

beacons of fixed frequencies located throughout the field. The vehicle will start at a fixed

location in the field. The mission is to locate the “next” audio beacon and steer the vehicle

toward that beacon while monitoring for the next beacon. The vehicle should continue to

search each consecutive beacon until the final beacon is located, indicating the vehicle has

exited the minefield. During the journey, the vehicle may not collide with any of the beacons

and must steer clear.

Vehicle Details: The vehicle consists of an aluminum chassis with three wheels (one front

center wheel, two rear wheels). Each rear wheel has a dedicated DC motor used to motivate

each wheel independently. Both DC motors are connected to a PWM motor driver unit that

controls the RPM of each motor independently based on a 2 PWM signals. The details of the

PWM motor driver are included in the appendix.

Microcontroller: Teensy 3.2 Real Time processor: This microcontroller will interface the PWM

motor drivers on the vehicle and the microphone sensor (and any other sensor you may

include). Plan to power the vehicle separately from the microcontroller. A four bank AA

battery pack is sufficient for the vehicle, while a separate power source may be used for the

controller. Do not power the motors through the microcontroller; it is not capable of providing

sufficient current. Battery packs may be purchased from [login to view URL] or adafruit.com.

Sensor Details: The microphone/amplifier assembly is described below.

Beacon Information: Each beacon is a piezo buzzer tuned to a particular frequency. Details

of the buzzer are below:

Rules:

1. You may use preassembled libraries for PWM signal generation and audio processing.

2. One group will be tested at a time. The vehicle will be placed at the starting point, and

the beacons will be turned on. There should be a “Go” button on the vehicle to start

the journey to the finish line as well as a visual indication (LED) that the journey has

ended

Hi! I already have a similar working prototype of this car which runs autonomously like a Tesla. I would only have to make a few tweaks so that the car runs on Audio signals. I also already possess a wide variety of Ar Mehr
