While it may be some time before robot swarms can eradicate tumors or eliminate the need for certain procedures, researchers are finding promising uses for smarter swarms.

From London to Venice, European swarm research around robots and drones is more than an academic exercise. It could provide the continent leadership in autonomous applications.

While the U.S. military has historically been a leader in the development of swarm robots, universities are also significant. Costs, controls, and applications offer opportunities for business.
