Shortly after my Thomas The Tank Engine phase, at the age of five I became obsessed with Lego and still am to this day. Since then I have been building and refining a Lego city that I am very excited about!

Here are some photos of my current Lego city layout!

For my 6th grade science fair project I built a working Lego Tic Tac Toe robot. A player would play the game as "X", while the robot would always play as "O". To make a move, a player writes an "X" in one of the boxes on the whiteboard, and presses a button to signal that their move is done. The robot has a memory of all of the previously occupied squares, and scans only the empty ones to see if there are any changes. When it sees that a square that was previously light color is now dark (using a color sensor), it knows the user must have moved their "X" piece there during the last turn. The robot calculates where it wants to move using a basic tic-tac-toe algorithm and draws an "O" at that square. The robot is programmed in RobotC, my first programming language. My dad taught me RobotC and also helped me out with a lot of troubleshooting on the initial design. I was originally planning to have the robot move around on wheels but instead only the x-axis was moved by wheels, with the y-axis moved by gears for better accuracy. The robot recalibrates itself at the end of every turn by moving to a corner until it hits a button, preserving accuracy thoughout the game.
