The algorithms that enable drone swarms is advancing EXTREMELY quickly. In the next couple of years, the number of advances in technology, deployments, use cases, and awareness of drones will be intense. In 5 years, they will be part of every day life. You will see them everywhere. Not just one or two drones. SWARMS of drones. Here's a video depicting experiments performed with a team of nano quadrotors at the GRASP Lab, University of Pennsylvania. Vehicles developed by KMel Robotics.
