Arduino-Automation-car

The handout for the project is:

Design and build an automatic robot hardware that

• explores the walled maze;
• stops at the treasure inside the maze and takes picture(s) of the treasure;
• leaves the maze and returns to the starting position;
• records the exploration and stores information for other parts of the system;

Extra functions:

• explores a more complicated maze (e.g. larger maze, with multiple splits/branches).
• self-designed other functions.

Hardware

Power

• Four wheels each with a motor
• Every two motors on one side is controlled by one l298n
• Each l298n connects to a same independent power source

Sensor

• Three kinds of sensors: ultrasonic sensor, Collision sensor, Color sensor
• Mainly depend on three Ultrasonic sensors
• The motherboard supply their power Uniformly
• Bluetooth module can send data from motherboard to computer

Algorithm

Exploration Strategy

Set a hyperparameter TOLERANCE representing the minimum distance to the wall:

if distanceForward < TOLERANCE (the robot’s head is too close to wall)
    Move(BACKWARD)
    If distanceLeft > distanceRight (the robot’s right is too close to wall)
        Move(LEFT)
    Else
        Move(RIGHT)
