A competition was held at SLIIT, where a Robot would be placed at one of the four corners and the task was to move to the centre of the maze in the minimum possible time three attempts were provided in order to study the maze.This was a team work and I took the most important part in the project, the algorithm.I decided to go for the flood filling method which was one of the most used algorithms in this type of competitions where each cell in the maze would be given numbers and during the studying of the maze, the numbers would be updated taking into consideration, the presence of the walls and the shortest distance to the centre of the maze, where there would be four squares with no walls in between them.In this competition, there were 196 squares(14x14) and the most challenging part was the hardware design because the length of one square was 16cm and therefore the Robot had to be made very small.And also for this project we had to go for the Pololu mini metal geared encoder motors.
Tools used:
1. Arduino Nano
2. Sharp IR Sensor
3. Pololu metal geared mini motors(encoder)
4.L298n motor driver
Reference:
The micromouse code, I learnt from this link.
