An ice cream company packages ice cream for delivery to local stores and for shipment to distant stores. Local packages have an ice cream decal on them and distant packages have a black shipment arrow. Both types of packages come down the packing line and must be placed on the appropriate shipping bin on the other side of the chute. The packages are bulky and difficult to move by hand.

Design and build a robot that will pick up the packages and place them into the appropriate bins. Write 2 programs that run for each sorting system.

The robot system design must include:

• A start button that commences everything
• A robot hand for gripping and releasing the packages
• A robot arm for moving the hand into the appropriate positions
• An area for picking up the ice cream packages
• An area for dropping off local packages and one for distant packages
• A green light must come on when the machine starts and remain on during the entire functioning period
• A red light must come on for 5 seconds when the arm has finished running
• A sound must play for a period of 2-3 seconds indicating that the machine is ready and waiting to be started

The program you design for each of the specific packages can contain the commands found on the LEGO DACTA COMMAND SHEET. Additional commands can be looked up under the Help -> Primitives menu.
