My progress on the my robot is going very well. I may even possibly be able to finish building my robot tomorrow and then only have the coding to do. Today, I managed to complete a method of detecting the ball and also opening and closing the exit. I used a sliding platform to close off and open up the exit below where the ball rests. The platform can move by a motor turning some gears. Tomorrow, I will build the part of my robot where the ball will enter. I will also have to build the lure.
