As the authors of the development wrote themselves, the Roller-Quadrotor is a new hybrid of ground and air quadrocopters. The bike has four drives that provide traction.
Engineers say their design overcomes the complex problems of conventional rotorcraft, reduces power consumption and allows for navigation on special terrains such as narrow passages. The problem of avoiding obstacles is also solved.
In their paper, the scientists present the vehicle’s design with a set of controllers that allow it to flip, fly and seamlessly switch between the two modes of operation.
