...who knows me knows, I have a bit of a thing for space elevators.
At first sight, this might seem to have nothing to do with it.
A tiny robot that can lift thousands of times its own weight while climbing up a wall?
The first thought I had, though, was that a swarm of these little robots (which stick to surfaces like a gecko) might be more efficient for spinning the tether than a few larger ones. The downside is that they move very slowly (which means this wouldn't be useful for climbers).
Another thought - these little clinging robots might have quite a few uses in microgravity.
