Bees' 'waggle dance' may revolutionize how robots talk to each other in disaster zones

Honeybees use a sophisticated dance to tell their sisters about the location of nearby flowers. This phenomenon forms the inspiration for a form of robot-robot communication that does not rely on digital networks. A recent study presents a simple technique whereby robots view and interpret each other's movements or a gesture from a human to communicate a geographical location. This approach could prove invaluable when network coverage is unreliable or absent, such as in disaster zones. Where are those flowers and how far away are they?
