so that first year you've paid the equivalent of 6k a month salary
then every year after that 1,000 a month salary to keep it running
that means it costs $96,000 over 3 years. A full time employee making $10/hr would cost roughly $62,400 over that same period. At that rate it would take nearly 7 years just to break even.
Also, it can only do 12 burgers at a time. At that point the biggest expense isn't the robot, it's the second grill and employee you'd need for the lunch rush.
on top of that, Most restaurants serve fish, chicken, or veggie burgers? All of these have very different cooking times and temperatures. Is this machine sophisticated enough to be able to detect how to cook all of these sandwhiches at once? How about artisan spots that make their patties from scratch? Does every new recipe require new programs?
The worst part is when the BRITISH TECH REPORTER described the burger as "pretty good." It doesn't bode well when a guy raised on mashed peas and blood pudding only kind of likes your food.
