Amazon offers to carry out the case for cargo in the form of a wing to improve the aerodynamic properties compared to a conventional box.
Previously, engineers from Ben-Gurion Universitycreated a robot from a wheeled device and a quadrocopter. The device has a housing with variable geometry and four screws that allow it to take off to overcome high obstacles.
