Researchers at the Georgia Institute of Technology are working on a rather amazing project as part of the program Mission Adaptive Rotor DARPA. THE US defense seeks new ideas to improve the performance of its helicopters according to changing flight conditions. In this context, the researchers were interested in the landing gear. They had the idea of replacing the traditional skates and wheels robotic legs. The device can thus rest on any terrain.
A train of robotic landing that fits the soil profile
While the storm rages, the helicopter approaches the frigate jostled by the waves. Only a few minutes of fuel, the pilot has no other choice but to ask his camera on the rear platform of the building.
After several attempts, the skill of the pilot finally allows him to get his device to the ship but the risk of crash was real. The device designed by the Georgia Tech researchers Suffice it to approach the platform remains horizontal. These are the four legs of the landing gear that will erase the pitch and roll movement of the platform. As the helicopter is able to land on a slope or on a flat surface necessarily. The device, mounted on a drone already seems to work in some configuration. The robot undercarriage allows the helicopter to land on a land with a slope of up to 20 °. Researchers ensure that their system does not present a significant weight in cost compared to a conventional landing gear. The researchers, decidedly optimistic about their invention considers these robotic legs will reduce the risk of hard landing by a factor of 5.
