Micro-Machines II - Locomotion

Since we were kids we hear that an ant can carry up to 30 times its own weight. Of course we wonder “If there was an 100 kilos ant, could it carry 3 tons?”. The problem is that such a big ant couldn’t probably lift her own weight.

The movement of a small animal or machine is much simpler than a big one. Whether is on the surface, on water or on the skies a smaller creature can move better, change directions easily, accelerate and brake easily and even coordinate movements.

Also smaller animals don’t need so big neurologic networks as the processing of their locomotion is easier. So micro-machines should use simpler ones as well. Once, we pass the tiping point of building a small enough processor for little machines to move around it will just get easier and easier build even smaller and more efficient ones.

The agility of a flying system is measured in a way by it’s turning radius. In other words, for it to take a 180º turning how many meters differ from point A to B?
A jet fighter has a smaller turning radius than a jumbo plane, therefore is more agile, but an eagle has an even smaller arch and a fly beats them all. This makes the fly’s manageability outstanding. It’s also interesting to point out that small birds have very bizarre flying methods with very small wings. On the other hand bigger birds usually fly faster but not that much.

In conclusion, while there is a wish full goal for robots playing soccer in 2050, we can expect much sooner for highly efficient means of locomotion for smaller machines.
