mBot-Maze-Race-Project

Introduction

This is a robotic project whereby the mBot needs to find its way through a maze in the shortest time. The mBot will be facing a number of challenges at intermediate waypoints while attempting to complete the race. The mBot must not bump into any wall by relying on a front ultrasonic sensor, and two side IR proximity sensors to accomplish this. Additionally, the mBot will have to sense colours and detect different frequency of tones.

Features of the mBot

• Move according to the commands (forward, backward, left or right)
• Ability to detect walls and avoid them using Infrared (IR) sensors
• Ability to detect colour of regularly shaped coloured objects (e.g. cube, cylinder) and change direction with respect to the colour (as per the code)
• Ability to detect frequency of sound waves and change direction with respect to the frequency(as per the code)
• Play celebratory tune upon finishing a maze

Overall Pseudocode

1. If there is a challenge:
   • Check the colour of the board above.
   • If the colour is not black:
     • Perform colour challenge.
   • Else:
     • Check if there is an audio input.
     • If there is an audio input, perform the audio challenge.
     • Else, play victory tune and terminate the program.
2. Else:
   • Align the robot and repeat from step #1
