Humanoid robots are probably never coming. The fact is - flesh and blood humans pay for their own upkeep. Wear-and-tear, particularly on a heavy lifting robot, would probably be their biggest cost and might always outweigh the cost savings.

[LeifCarrotson]

I've commissioned dozens of robot cells (6-axis industrial arms for manufacturing are old, proven tech) and the wear and tear costs have been inconsequential. Even a large arm like a Fanuc R2000iC only uses about $0.50 in electricity per hour, some cells use significant power for pneumatics (in particular, compressed air venturi vacuum generators).

A couple grand for gearbox rebuilds every few years, replacement vacuum cups or worn hard tooling as needed, troubleshoot electrical issues as they arise... and your quarter million robot cell ($60k of that is the robot, most of the rest is NRE labor) will only need one human instead of eight to spit out parts every 60 seconds for the next decade.

Unless you think the humanoid robots are going to wear out significantly faster than existing robots, wear and tear costs are negligible.

With tight process controls, turning a work cell that has multiple humans doing manual labor for material handling, fastening, inspection, labeling, etc. into one intelligent human keeping the automation well adjusted is a solved problem. Eliminating that last human - the one that makes decisions instead of moves materials - with a humanoid robot is going to take decades.

We can make things that last for decades, we just choose not to. Planned obsolescence is a business strategy, as is rapid breakdown of things we buy.

A generic example, fridges could easily last 40 to 50 years without maintenance. They wouldn't be all that more expensive either. Volvo, and the B-52 bomber program showed this, with Volvo having some models unchanged for 20 years. The B-52 has been in service longer than most people have been alive.

Each time an early wear or failure point is found in the B-52, it is documented, fixed, and rolled out to all B-52s. Their ancient, but more reliable than newer bombers and require less maintenance.

We could do this for everything. Design a fridge, and after 10 years collect the failures and see how they broke. Keep selling the same fridge, the same parts, and eventually it's a rock.

We don't do this, companies don't do this, because it's not best for profit.

So my point is robot maintenance could be minor, and if it was purely a lease model, would remain minor... because the company would profit from lower overall maintenance costs.

Lastly, compare a robot to a car driving 100s of thousands of KM. I've driven new cars to 150000km with almost no failure of any kind (except brakes. tires). So maybe not as bad as thought.

B-52s require regular inspections and maintenance just like any other aircraft. A fridge is less complicated, but it's still a machine. Even my grandfather's clock needed some work done every couple decades, and it didn't contain refrigerant, a compressor, fans, or have to deal with condensation.

Neither Volvos (presumably, a reference to their cars) nor B-52s are maintenance-free, even if they have long service lives with proper maintenance, so I don’t see how either supports your argument that fridges could easily be made to last decades without maintenance.

If a robot costs $50k, lasts 5 years, and does the dishes and laundry every day, I'd consider it.

[mdavid626]

Isn’t that the dishwasher and the washing machine?

[zdragnar]

Human flesh and blood is pretty bad at upgrading itself, too. A sapient robot, or one with specific programming, might adapt itself as parts wear out when individual components, limbs, and other odds and ends are separately serviceable.

[the_sleaze_]

Cost of human is much higher. Taxes, healthcare, breaks, brain-damage related to their emotional maintenance, safety requirements, etc.

No reason a robot can't work in a dark cave flooded with radon, and that is going to be cheap real estate.

[qgin]

I think it depends on the application. Employees tend to not be free in the 21st century at least.

[Teever]

Have you factored in the ability for humanoid robots to be able to do preventative maintenance and repairs on each other?

In many instances with repairing electronics and home appliances labour is the greatest cost, not the material. Sometimes it's as simple as replacing a 50 cent washer to repair something, or perhaps squirt some lube here or there regularly to prevent something from breaking down.

If it's the same for robot maintenance then robots being able to fix themselves and each other will change the equation on ownership tremendously.

Imagine if everyone had a domestic robot and if it broke down their neighbour's robot could repair it. That would be an extremely user friendly and cheap way to deal with the problem.

[sjsdaiuasgdia]

This makes a lot of assumptions about the field service potential of humanoid robots. A humanoid robot is so much more complex than something like a washing machine. There are far more things to break. Assuming humanoid robot maintenance will look like general appliance maintenance may not be a robust assumption.

"Replace tiny parts" option - Which parts is the manufacturer making available for purchase and what does the supply chain look like for that? What tools are needed to do the disassembly, part installation, and re-assembly? Can a humanoid robot out in the real world replicate the clean room conditions in which delicate components were assembled then sealed inside some compartment so dust can never get to them? Are we going to put heat guns and soldering irons in the fingertips of every humanoid robot to support self repair? There's going to be problems that can't be resolved with the kinds of tools available in the average household.

"Replace modules / components" option - Having to buy a whole new hand when you really wanted to replace a single finger joint impacts the value proposition of self repair, it's not a 50 cent washer it's a $1000 pre-assembled component. The repair is now definitely doable in the field, at least.

You might also be assuming humanoid robot manufacturers would not work specifically against self-repair. They make more money if you buy a new robot, or you pay them to fix your broken robot. Maybe "fix this other robot" ends up on a list of forbidden tasks the robot will always refuse to do...
