In the past few years, we have seen plenty of clever uses for drones. The Palletrone Cart is a flying cart for transportation. It can go where conventional wheel-based carts can’t go. For example, you can simply use it to take your things up and down the stairs.
The Palletrone Cart uses a disturbance observer robust control algorithm to estimate and compensate for external forces. As the above video shows, this flying machine can transport cargo in ways regular carts simply can’t. When you are loading and unloading, this flying cart won’t change its altitude.
