This cool project was built by a Danish company, Valhalla Drone Solutions, a group of seven engineers from the University of Southern Denmark in Odense. It’s a Lego Mindstorms robot that automatically switches a quadrotor’s battery pack.
When the drone lands, it’s positioned by a belt, an assembly pops out, and the old battery is lowered out of the quadrotor. That battery is placed into a rotating disk that spins to position a fresh battery, which is then placed into the drone.
What is really cool, however, is that this is the prototype for an actual product Valhalla hopes to sell, which they call the Odin Platform. One role they envision the product filling is resupplying agricultural drones. Way cool! [via The NXT Step]
