Smallest remote controlled robot

Video transcript:
The crab bot is a tiny robot even smaller than a flea.
AND OMG It’s so cute!
The robot moves by getting hit with a laser beam that rapidly heats various parts of its body, that then also rapidly cool down & return to their original shape.
It also moves at a speed of about half its body length per second, so it’s a heck of a lot slower than a flea.
And these robots can pretty much be created at almost any size or shape.
Very awesome to see these tiny robots, that could be very useful in the future.
For instance maybe a surgent could use a few micro robots to unclog a clogged artery & so on.
Very awesome.Show more
