Assignment 3 - Alejandro Frias and Tyler Marklyn (Team #9)

I actually found that slightly confusing. In the empty maze where you go forward and left until you reach the corner, you say "Go left whilst(open on_left)" which implies turn left, then go forward until blocked? This is intuitively clear, as in, it's easy to see that that is what you want to do, but you have to suspend disbelief about the picobot's orientation until the block is reached. 

I guess you wanted to word it this way, since that's how we give instructions in real life "Take a left at the light, then take a right and the second crossing," or something, but we don't say "Go left at the light, then go straight at the first crossing, then go right at the next crossing."
