No Time!

I need to have something to present in 2 days so I'm just throwing something together quickly. Last night I wrote a program using the XNA game engine and embedded it into a winforms application. Basically it's a blue screen with a black box with 4 usable functions: MoveUp() MoveDown() MoveLeft() MoveRight(). Today I added my serial code to it and I am able to move the box around the screen through serial commands. Tomorrow I'll have to program some simple obstacle avoidance algorithm into one of the robots and get it to pass info every time it runs into something so that the program will be able to update the box's position. Luckily the science fair isn't for another month.
