Mexican: First fully-automated taco assembly line that can build a taco containing ground...

...meat, lettuce, shredded cheese, chopped tomatoes, and sour cream.  Wrap the taco and put it onto a warming tray where order takers can grab it and put it in a bag or on a tray.  To prevent cross-contamination for those with food allergies, the machine then washes and sterilizes whatever manipulators it used to assemble the taco before making the next taco.  To win this challenge, the machine must be installed in a real-life restaurant, operate continuously for at least 1,000 hours without error or malfunction, and serve at least 30,000 tacos to paying customers.

Future Challenges: To win the following future challenges, the machine must be installed in a real-life restaurant, operate continuously for at least 1,000 hours without error or malfunction, and serve at least 30,000 food units (e.g., burritos) to paying customers who must then fully eat them. First fully-automated:

1) Burrito assembly line.  Build a burrito, then wrap it up and put it onto a warming tray where order takers can grab it and put it in a bag or on a tray.  To prevent cross-contamination for those with food allergies, the machine then washes and sterilizes whatever manipulators it used to assemble the burrito before making the next one.

2) Fast food Mexican restaurant (including check-out counter and drive-thru).

3) Fast food Mexican restaurant owned and operated by a fast food restaurant chain (100 units or larger).

4) Mexican restaurant chain (100 units or larger).

5) Major Mexican restaurant chain (1,000 units or larger).
