Assume that a robot mechanic makes $35/hour direct with a weighted rate of $80/hour (health, 401k, etc.) and can do PM on 10 machines a week. The robot only costs $30,000 up front and costs $3/hour to operate from what I read. Assuming that a restaurant runs for 10 hours a day for 350 days per year. That's a labor cost for the burger flipper of 3500 hours/year. Assume a direct wage of $8/hour with a weighted wage of $10/hour to make the math easy. That's $35,000 per year. Using the same usage assumptions the yearly operating cost of the burger robot is $10,500. Now assuming a 2 year payback, ignoring the interest rates to make things simple again, although a bit low, the investment on the machine is $15,000/year for 2 years. The cost of the mechanic per machine based once again upon weighted pay is $16,000/year. That's a total of $41,500/year for the robot burger flipper. If I do my math correctly after that, it means that human flippy can get his base wage raised to around $9.86/hour with no increase in weighting and the costs will break even with robot flippy. If the machine price comes down, my maintenance numbers are high, hours used is higher, or that $3/hour operation includes maintenance, robot flippy is already competitive. $15/hour will put most of the short order cooks in the USA out of business, of which there are estimated to be 150,000.

It seems that Biden and his cronies want to put the whole country out of work.
