Software
Functions that definitely need work:

• Algorithm to explore the maze; how should it prioritize the mapping
• How will the bot get back to the start of the maze after mapping
• Function for keeping centered throughout the maze

Functions written but not perfect:

• Recursion algorithm for solving the maze after mapping; it outputs a string of directions
• Execute the shortest path to the goal
• Square's goal state; if the robot is in one of the middle 4 squares, the goal state changes to 1

Hardware
We need a battery with 9~18 Volts and 2~3 Amperes to support the stepper motors. After getting the battery, the bot will not be tethered to the power supply!

Data sheet for DC converter: http://www.cui.com/product/resource/v78xx-1500.pdf

• Max Vin = 18V
• Min Vin = 6.5V

Data sheet for motor driver: http://www.ti.com/lit/ds/symlink/drv8805.pdf

• Max Vm and Vclamp = 60V
• Min Vm = 8.2V

To Do List

• Think of ways to test mapping algorithm; can we print out the informational vectors?
• Create informational vectors for a fake maze; test recursion algorithm; can it find the shortest string
• Research and purchase battery
• Get IR sensors set up and create graphs of distance and voltage
