RoboEarth is a World Wide Web for robots: a giant network and database repository where robots can share information and learn from each other about their behavior and their environment. Researchers behind it hope it will allow robots to come into service more quickly, armed with a growing library of knowledge about their human masters. It is likely to become a tool for the growing number of service and domestic robots that many expect to become a feature in homes in coming decades. RoboEarth researcher Dr Markus Waibel from the Swiss Federal Institute of Technology in Zurich said, if a robot could enter a location that it had never visited before, consult RoboEarth to learn about that place and the objects and tasks in it and then quickly get to work. RoboEarth could help a robot understand what is meant when it is asked to set the table and what objects are required for that task to be completed. Hopefully robot will not control human.
