I think we might be talking past each other.

I’m not arguing that humanoids are the only robots that can operate in human environments, nor that specialized robots shouldn’t exist. We already know they should, and do, and work very well.

I’m saying it depends on what you’re after.

If you want a specialized machine, then by all means optimize the form factor for that task.

If you want a general-purpose platform, then you’re faced with a near-infinite variety of environments, tools, and situations: homes, offices, hospitals, factories, hotels, streets…

Almost all of them were designed around human reach, dexterity, height, mobility and perception.

> The moment you have mobile tools, whats the point in forcing the robot to hold them using a human hand? You can put them on a tool changer now or have a gripper that works for the specific task. Why does a robot need to hold a wrench using a humanoid hand?

It doesn’t. The wrench was just one example among many. Nearly all our tools and interfaces are designed around human hands and bodies. If a different manipulator works just as well across all of them, great. My point isn’t that it must literally be a human hand.

> I think its incredibly unreasonable to suggest that you need to solve every single problem ever encountered in human existence to be allowed to solve one much simpler problem.

That’s not what I’m suggesting.

I’m saying it’s a deployment strategy. Start with the form factor that’s already compatible with the largest installed base of tools and infrastructure. Not because it’s mechanically optimal, but because it minimises the amount of adaptation required from the market.

And enables you to sell to markets you aren’t even aware exist.

If, over time, you discover that hands don’t need five fingers, legs don’t need knees, or an entirely different morphology delivers much better performance, then you have both the experience and the demonstrated value to justify changing the robot, or even convince your customers to change the environment to fit a better robot.

They’re basically trying to go for the "one size fits most" of robotics. And yes, we both know how well that usually fits anyone.

I’m not convinced either, but I can understand the logic.
