This was the beginning of robotics for me. For Spring 2015 the IEEE branch of New Orleans was tasked with coming for the rules of the robotics competition. The competition board was designed to be a simply connected maze. That means only a single shortest path was possible for the maze. There was only one entry point and one exit point. Each block of the maze was 12 inches by 12 inches square with some squares separated with a wall between them. The acutal size of the board was 8 feet by 8 feet. As a part of the bonus some colored walls had ascii characters imprinted on them. The recognition of those letters meant bonus during the competition. A detail of the competition rules is shown here.

The playing field was:
The competition was to be held by the University of New Orleans (UNO) and so UNO couldn't compete in this competition. Traditionally, these competitions were taken to be capstone projects for seniors but no one could compete for the prize and no senior took part in this competition. So, 2 freshmen, me and Andy Stark decided to build the robot. The chassis was designed in solidworks and then later 3d printed. This meant no issues with alignments of the wheels and motors and the placement of sensors was also easy. Arduino was used to program the robot, stepper motors and mecannum wheels were used for motion and ultrasonic sensors (distance measuring) sensors were used to find the location of the robot and align the robot. The video provides a sample run for a small maze. Initial run was made to run the robot from starting point square 46 to find the path to the end point square 33. So, the robot scours the area for the smalles path. Then the dead end algorithm was used to find the shortest path from square 46 to square 33.
