InteligentCar_WallFollwer

For my physic first year project I decided to build a autonomus car that follow the perimeter of the wall on the right.

Circuit Diagram

Tinkercad

Components

• Arduino Uno (x1)

• L293D (x1)

• Distance Sensor (x2)

• Motors with GearBox (x2)

• 9V battery (x2)

• Bradboard (x1)

• Switch off/on (x1)

• Wires male to male

• Wires male to female

• Giroscopic wheel

• Solid plastic easy to cut for structure

Controll

It uses two distance sensor, one on the front one on the right side, to detect his position in comparison to the wall. Using a Truth table I set down all th cases possible:

FOR RIGHT SIDE

• ToCloseWall

• ToFarWall

• Correct

FOR FRONT

• WallInFront

• NoWallInFront

This 6 cases are reflected in the code.

L298N (Speed control, DC motor voltage 5-35V, Direction control, Peak current 2A), connect to 2 motors with wheels. The L298N is connected to the arduino and gets information from the distance sensors

Evaluation

The car don't miss!! Almost never tuches the wall. The problem and possible improve can be a better way to power the car
