Harrison Bourne worked on this project with a simple aim to create a car that could be administered through a simple controller like TV remote. The basic stage included normal movements like moving forward or backwards or turning to right or left or start or stop with a single command. There were a lot of other things that he wished to with this innovation like adding speed to the car with remote control or power the motors and Arduino with batteries in place of using power cables. However, there were challenges that restricted the scope and his efforts.
The first hassle came in with respect to interpretation of IT signal that was being sent from the television remote control. For this, he installed an IR receiver diode that converted the IR signals from TV remote to electric signals. Next issue was with respect to coordination between the pulse that has been sent and the specific key that had been pressed. Next, was respect to creation of Chassis. He sorted out the last one by creating a simple rectangular frame from an aluminum angle in order to complete his project.
The biggest part of the project was dedicated to formation of driving and steering system. To accomplish this task, he used two DC motors that could both steer and drive the car. One of the biggest requisites of this project was a front wheel drive option and a single wheel on rear end that could turn around freely. Whenever the car is instructed to turn to any side any of the motors will slow down simply or might stop completely. Since, he wanted to use DC motors he also needed a motor controlling chip that can change both speed and direction of the motors. He mainly intended to utilize the FAN8082 that was needed in midterm project.
