The killer app for robots: folding towles

We had been wondering for a quite a while what robots could actually be good for in the household. Throughout the last years the succesfull examples have been the vaccum ceaner Roomba and a number of lawn mowers. Now there is another application, folding towels - look impressive!


And it's not an April joke

Immersing into a robot

Just before christmas a new toy has arrived, the rovio robot. It really does look frightning (though the developers designed it to let hard working parents remotely communicate with their kids at home...)



Actually, it's not really a robot it's rather a remote controlled toy. The rather limited autonomous features, such as 'go home to base' or 'follow path' do not work that well (see also reviews at amazon).
However, it's funny to walk through a shared office space late at night spying on who's still there. The exciting part also is, that the other one doesn't see who's currently controlling the robot (showing it could also be a nice feature though). You really start immersing into the robot while controlling it through the web-interface. You learn the dimensions of the robot know what you can pass and what you can't. Navigation in the dark is rather poor, but luckily we our office lights react on motion. Another exciting part are colleagues the get annoyed and carry the robot away (which corresponds to 'tele-porting' in computer games) and you have to find your way back again to the base station - hopefully, before rovio runs out of battery.
Despite it's limited functionality and it's current flaws Rovio is really fun.

The first robot in my home

Many keynotes and talks concerning ubicomp/pervasive computing and 'internet of things' conclude with "Sensors are only the beginning...actuators will be next...".
Indeed, we are getting there. Robots are slowly entering homes mainly lawn mowers and vacuum cleaners [1]. In [2] the developers of Roomba clearly explain why single purpose robots, e.g. vacuum cleaning, convince consumers instead of everything-else-slaves nobody can yet believe in.
Meanwhile, we bough a robot for our lab. I immediately took it home and tried it out:


My experiences completely match with [3]: Roomba does not really clean well, but it does it automatically, so who cares? It works without intervention and it's just fascinating. The device is rather dumb, which is nicely described as 'random walk': it just goes straight, turns around obstacles and wanders criss cross around the room which the instructions call 'robot intelligence to efficiently clean the whole floor'.
Anyway, Roomba is a rather cheap and robust platform. Even if its dumb, attaching a mobile phone will offer new opportunities for developing applications [4]. Stay tuned...
