the Nature limited us to just 2 hands for all tasks and purposes. The humanoids have no such limitations.

>10000 sensors with specific spatial layout and various specialised purposes (pressure / vibration / stretching / temperature) that require different mechanical connections between the sensor and the skin.

mechanical connection wouldn't be an issue if we lithograph the sensors right onto the "skin" similarly to chips.

Sorry, I meant to emphasize _different_ mechanical connections. That a sensor that detects pressure has a different mechanical linkage than the one detecting vibration. So you need multiple different manufacturing techniques to replicate that at correspondingly higher cost.

The “more than 10000” also has a large impact in size (sensors need to be very small) and cost (you are not paying for one sensor but 10000).

Of course some applications can do with much less. IIUC the article is all about a _universal_ humanoid robot, able to do _all_ tasks.
