Robobees are nothing new. Plenty of researchers have explored them in the past. A team of scientists from the University of Graz, Austria have developed autonomous little robots that interact with bees and are accepted as their society. The goal is to use these robots to study the bees’ behavior from inside the hive.
This study runs under the ASSISIbf project. As it turns out, EPFL researchers have developed a cool fish robot under the same project. You can find out more here.
