Helping robots find their way in the city

February 9, 2011

Many approaches to developing cities as automated environments, whether this be for robotics, for augmented reality or ubiquitous computing tend to take as their premise the addition of items, generally computing devices, to the environment. Thus, for example, RFID chips can be embedded in buildings and objects which could (and indeed in some cases, already do) communicate with each other and with mobile devices to form networks to enable all kinds of location-based services, mobile commerce and of course, surveillance.

But for robots in the city, such a complex network of communication is not strictly necessary. Cities already contain many relatively stable points by which such artificial entities can orient themselves, however not all of them are obvious. One recent Japanese paper, mentioned in Boing Boing, advocates the use of manhole covers, which tend to be static, metallic, quite distinctive and relatively long-lasting – all useful qualities in establishing location. The shape of manhole covers could be recorded and used as location-finding data with no need for embedded chips and the like.

It isn’t mentioned in the article, but I wonder whether such data could also be used for other inhabitants of the city with limited sensory capabilities: impaired humans? Could one equip people with devices that read the same data and use this to help sensorially-impaired people to navigate the city more effectively? On the less positive side, I also wonder whether such data would prove to be highly desirable information for use in urban warfare…
