Lego Mindstorms NXT 2.0 Color Ball Sorting Robot
By
This video demonstrates the color ball sorting robot in operation. I enhanced the program so it stops after three consecutive errors (no balls, or ball jam) and used variables to store the amount of rotation needed to return the tray to it’s default position after placing a ball in a slot instead of repeating that code for each color branch. It also displays and increments counter each time a ball is placed in a slot.
