Robots can navigate autonomously within buildings, using only magnetometers and detailed maps of local magnetic anomalies.
The technology could provide a means for humans and robots to find their way around large buildings, but could be some way from commercial application due to the high cost and size of the sensors.
Satellite navigation systems such as Russia’s GLONASS, the European Union’s Galileo and China’s Beidou can all provide accurate location information…
