> How Much Do New Robots Cost? Complete with controllers and teach pendants, new industrial robotics cost from $50,000 to $80,000. Once application-specific peripherals are added, the robot system costs anywhere from $100,000 to $150,000. Reconditioned robots are a less expensive option. Typically, used robots cost half as much as new robots. Used robot prices can range between an estimated $25,000 and $40,000, and systems with application components cost between $50,000 and $75,000.

Just checked out a random pizza hut and seems to be open 11 AM - 10 PM daily or 11 hours a day or 77 hours a week or 4,000 hours a year. That'll cost about 30k a year at minimum wage not counting overtime, training, hiring cost, taxes, etc.

Probably not, or at least it won't be at scale. Dominos employees need managers, benefits (of some sort), payroll, legal and HR.. liability insurance for when they get pissed off and do something nasty to another employee or a customer.. they cost a lot more than the hourly.

There's nothing intrinsically expensive about a robot arm. It's few motors, sensors, metal, plastic, and something like a raspberry pi. With cheaper components and volume production a robot arm could cost less than a Domino's employee makes in a week.
