Create a program to control the robot to put all 4 balls into the matching holes. In this template, the robot is controlled by keyboard input ('Up' to move, 'Left' and 'Right' to turn and 'Space' to pick up/ put down balls). You have to replace these keyboard controls in the sprite "Controller" to make the robot play the game autonomously. https://scratch.mit.edu/discuss/topic/214237/
My WIP entry for the ATC#6. I'm not sure if I'm gonna continue with it yet, there are some bugs and performances issues that may or may not have simple fixes ATM. Once both the left/right and top/bottom boundaries are found, it will display all possible remaining position for each of the balls.
