Can you tell me a little bit more about that?

Yeah.

That is an area that there's a lot of research on because there's lots of parts of our body that are hard to get into, and there's potentially easier ways to access them with robots.

So different roboticists are working on either micro robots, which are small enough to get into some of our bigger veins and arteries to potentially clear it or even smaller that can cross over blood barriers that require much smaller robots, and they can deliver medication, clear out problems, even go in and maybe just do checks in the future to see how the body is going.

So it's a future where you swallow some robots and then they are made of biodegradable material, and once they're done, they are absorbed into your body like any other thing.

And how do researchers think this technology could develop even further?

One of the interesting things I heard was, although so much of this is around tiny robots, like they could be larger robots, which as an example in the story, someone mentioned that we could start to see drone delivery, which is something that Amazon is already working on, but they are doing that with single robots, but that also could be done by swarms, which would be able to potentially take larger packages 'cause there's more robots.

And the other thing I found really interesting was a swarm doesn't necessarily need to look like a giant flock of birds.
