TECH:aerial robotics

Once in a while there appears a new technology that promises
dramatic social changes. It often comes unexpectedly, from some
modest-looking area of science and engineering, and I always
wonder what is going to appear next.

One candidate for such new technology may be aerial robotics.
People have been working on mobile robots for a while now.
The most difficult issue with walking robots seems to be
orientation in the environment.
Image recognition is a very costly and difficult task, and it
is essential for moving around on land. Not that much in other
environments though - like air or water. There are additional
difficulties of aerial robotics: the craft must have efficient
and light-weight equipment for position identification and
communication - but these problems are now resolved with
cellular modems and GPS.
So now you can build little blimps, planes and helicopters
that can fly around and do things. Aerial robots may free people
from many tasks that are "dull, dirty, or dangerous" (D3) - or
costly: a pigeon-sized flying robot may quickly accomplish missions
- like deliver your pills from the farmacy, or take a picture of
a corn field from the air - that now require a car or a helicopter.

You don't have to own an aerial robot. They may be available for
hire at a very low price (a few dollars an hour or less), and you could
rent one for a 5-minute mission for a quarter. The robots could also
refuel themselves at automated gas stations, paying with digital cash
there - so they will require minimal maintenance from an owner.

Now, let me list some interesting things that aerial robots could do:

- collect information: a flying robot can visit places, or follow objects,
and record and/or transmit everything it can observe. That allows you
to fly a little craft with a camera around the Great Canyon, or above the
Eiffel tower (you can control it via Internet, and get images and
sounds back), "virtually visiting" a real museum by flying a WebCam-
equipped blimp through its halls, following wild animals and cute
girls, spying after [potential?] criminals or anybody else, etc.

[ An interesting issue here is that it may be very difficult to identify
who the robot is serving at any particular moment. So physical tasks
can be as anonymous as Internet communications. ]

- deliver small physical objects. Getting pills or apples is one example.
There are more fun things to do though. You can drop a dead frog
on your neighbor's head. Or spray some foul substance over a crowd.
Or deliver drugs - quickly and anonymously. Or shoot somebody from
the air. You can also steal small things by driving robots remotely,
or teaching them to pick up rings, dollar bills, etc.

It seems that the features of small aerial robots - being aiborne,
cheap and anonymous - allow to do lots of things from which the society
doesn't have much protection. Introduction of aerial robots that is
likely to happen on a large scale within the next 5 to 10 years, may
deliver multiple benefits, and at the same time create quite a turmoil.
- And wait until we have lots of swimming and running little robots.
