Hovering for more than 20 seconds, the research of Guanggong flying bipedal robot has made the latest progress

Recently, the "Intelligent Detection and Control Research Team" of Guangdong University of Technology (hereinafter referred to as "Guanggong") has made the latest progress in flying bipedal robots. The robot has been greatly improved in the control system and control algorithm, can feedback the position information through its own attitude sensor and motion capture system, with the help of the new control method, vector propulsion control through the duct fan at the sole of the foot, successfully achieved a fixed-point hover flight in the air, and maintained more than 20s. This achievement provides the basis for subsequent robots to carry out air maneuver flights in complex environments and take-offs and landings on complex terrain.

Members of The Intelligent Detection and Control Research Team of Guanggong demonstrated hovering by a flying bipedal robot.

Allowing humanoid robots to have the ability to fly is currently a hot spot in the frontier research of international robots, including the University of Tokyo in Japan, the California Institute of Technology in the United States, and the Italian Institute of Technology and other institutions competing to carry out related research.

In recent years, research institutions led by Boston Dynamics in the United States have continuously made breakthroughs in the dynamic walking stability of humanoid robots. However, due to leg length and joint dynamics, robots can still be helpless in the face of large obstacles or trenches. Enabling robots to have the ability to fly over short distances, flying across large obstacles and then switching to low-energy bipedal walking mode is an effective means to improve the robot's ability to move in complex environments.

According to the relevant person in charge of the "Intelligent Detection and Control Research Team" of Guanggong, Guanggong's Jet-HR2 is currently the world's largest and largest (17kg) bipedal robot with controlled hover flight. All of the robot's current power is provided by the battery and mounted on the robot. The biggest difference between jet-HR2 and other institutions at the current international frontier in the program is its thrust layout, the robot lays out the bypass fan on the sole of the foot as the main propulsion device, and realizes the air attitude maneuver through vector propulsion control. This design has higher air maneuverability than other solutions, especially under conditions with low thrust-to-weight ratios.

The person in charge said that at present, the project is still in the stage of laboratory theoretical verification, and the next step will be to carry out research on aerial attitude maneuvering, complex terrain take-off and landing, and composite modal motion control, and at the same time, the hardware of the robot will be further upgraded to achieve the application of outdoor practical scenes.
