Fotokite, a Swiss startup that specializes in first responder drones, has just launched a new product to make deployment even quicker. Its drone takes off right from the roof of an emergency vehicle. Rooftop, as the product is called, is essentially a box that mounts to the roof or roof rack of a vehicle. When first responders arrive on the scene, the box opens up, revealing the company’s Sigma hexacopter. Rooftop doesn’t just house the done. It also provides continuous power and data link through a 150-foot tether.
