I work part-time at a Pittsburgh startup. We build quadcopters with base stations for aerial mapping of industrial sites. I design and manufacture all of the circuit boards used in the quadcopters and base stations.
A system includes a quadcopter and a base station. The customer remotely logs into a web interface and draws out a flight plan. The quadcopter takes off, equipped with a suite of sensors and cameras, and flies the route on its own, guided by GPS. When complete, the quad returns home and lands on the base station. The base station swaps out the battery on the quad for a freshly charged one, and uploads the imagery for the customer to view.
