A robotic arm takes packages from three conveyor belts (labelled A, B, and C) and moves them to the conveyor belt labelled OUT. The rules for the robotic arm are as follows:
If there is a package on belt A, take one and move it to belt OUT. Then,
if there is a package on belt B, take one and move it to belt OUT. Then,
if there is a package on belt C, take one and move it to belt OUT. Then,
move to belt A and start again.
If the robotic arm is ready to take a package from a particular belt, but no package is available there, the robotic arm will shut down.
