Dustbot
Dustbot is a robot that can collect garbage from homes. It can be summoned by phone call or SMS, and uses GPS to automatically make its way to the customer, collect the rubbish, and take it to a dustbin. In addition, the Dustbots carry environmental sensors to monitor the pollution levels over, for example, a pedestrian area. Prototypes have been tested in Italy, in Sweden, in Korea and Japan, and it is due for launch in 2009. The Dustbot project is funded by the European Commission.
