i mean controling the external body like limb and such without internally going into human brain or mindcontrol using nanobot, or going inside human skin or nerve (contact with skin is fine but not something like going inside muscle or skin etc).

so the person is controlled like puppet but still conscious or aware.

  • $\begingroup$ I am not sure I understand your question: you want to use nanobots without having them in or on the controlled body? $\endgroup$ – L.Dutch - Reinstate Monica Jul 15 '19 at 5:28
  • $\begingroup$ without interfacing brain-, nerve-, or muscle tissue that is pretty much impossible. you could encase the whole human in a thick shell of nanobots, but what would be the point? $\endgroup$ – bukwyrm Jul 15 '19 at 5:30
  • $\begingroup$ yeah but i mean its fine on the controlled body or externally though $\endgroup$ – Li Jun Jul 15 '19 at 5:30

    $\begingroup$ You need to expand your story greatly. A nanobot is tiny so we have to assume you are using millions of them. Not entering the body really defeats the whole point of nanobots. Where and what is controlling the nanobots? $\endgroup$ – Thorne Jul 15 '19 at 5:32

    $\begingroup$ Are you thinking of something like a tens unit? $\endgroup$ – Cort Ammon Jul 15 '19 at 5:44

Control of the muscles of a human body is limited if one remains outside of the body. We do have some limited ability to do so using electric fields, such as those produced by TENS units. These can cause a muscle to contract.

However, such contractions yield very little control. Our muscles are organized into muscle units, which are small groups of fibers within a muscle that always contract together. Our bicep has about 53 of them, and we recruit them in various orders to have fine control over our motion. If one is using TENS style electrical fields, it's hard to affect them one at a time -- you tend to contract the whole muscle. An individual being controlled in this way would be jerky, like a zombie.

To get a sense of what it would be like, consider playing QWOP, a game which challenges you to run by controlling the leg muscles directly.
