Teamwork among honeybees keeps a hive running smoothly. Worker bees collect pollen, nurse bees care for larvae, and male drones spread the colony’s genes. Each insect’s efforts ensure the colony’s success. That strategy led Gu-Yeon Wei to suggest that Rob Wood morph an almond-size robotic fly he had developed into a fleet of autonomous bees, each capable of carrying out specialized tasks. Perhaps, they speculated, the “RoboBees” could supplement the pollinating duties of bees stricken by a mysterious affliction that’s killed 36 percent of America’s 2.4 million hives.
