US made the latest robot aircraft without GPS to self-navigate

For decades, building a robotic aircraft capable of flying automatically has been the goal of many scientists. Recently, the Massachusetts Institute of Technology's Robotics Research Group announced that this dream has become a reality and successfully developed an aircraft that can self-navigate without using the Global Positioning System (GPS).

It is reported that this fixed-wing aircraft can self-maneuver while maintaining high-speed flight, avoiding obstacles in narrow spaces.

In appearance, the robotic wing is two meters long and weighs two kilograms. It can fly for 7 minutes at a speed of 22 miles per hour (about 35 kilometers). In terms of internal construction, its parts look very simple, with only sensors, laser rangefinders and a basic Intel processor.

Nick Roy, associate professor of aeronautics and aerospace at the Massachusetts Institute of Technology and head of the robotics research group, said: "In appearance, we made it into a fixed-wing aircraft, not a helicopter. We believe that the fixed-wing aircraft's sustainable flight time It’s longer, because it’s very difficult for a helicopter to fly. But we want it (robot) to fly farther and fly longer.”

Currently, the aircraft's laser rangefinder can only provide a two-dimensional picture of the surrounding flight environment. In this regard, researchers at the Massachusetts Institute of Technology also need to upload high-resolution digital maps of the flight environment to the aircraft for reference.

The research team said that they need to improve the aircraft's ability to detect the flight environment before putting it into practice.

After the researchers published the results on the Internet, netizens commented that “this is the best innovation” and “what is what humans do”.
