µTug: Micro robot pulls 2000 times its weight

[made2hack]

A 12 gram "micro tug" robot moves objects 2000 times its size on glass (steel objects without wheels or lubrication) enabled by gecko adhesives. This capability is comparable to a human dragging a blue whale. Even if the human was strong enough, their shoes would just slip making this impossible without this micro robot's special gecko inspired "shoes."

Impressive but bear in mind the 2000× its own weight benchmark won't scale linearly so comparing it to something the size of a human being able to drag a blue whale is not a fair one.

Exactly what I was thinking. It's 12 gram and what, a couple of cm³, I'm 120000 gram and I'd guess about 90000 cm³. I may not be proportionately as strong but I bet I can move myself and that cup for less energy than the µTug can move the cup..

A flea can jump higher than any other animal in proportion to its height but that's only because it's so damn small and the same goes for ants that can carry several times their bodyweight. A domestic cat can also jump higher relative to its height than a cheetah

Gravity is less of an issue for  small things.
