Background

With the rapid development of the robot technology in China, the functionality, flexibility and intelligence of the robot technology become increasingly complete. The appearance of different types of robots not only brings great convenience to daily life of people, but also plays a great role in industrial production, and some robots are used in the military field, so that the robot technology has great development potential. Therefore, more and more researchers hope to widen the moving range of the robot by improving the motion form of the robot, so that the robot has greater utilization value.

At present, wheel type, foot type and wheel foot type robots mainly exist at home and abroad, and some research institutions innovatively research and develop air-ground dual-purpose robots. The air-ground dual-purpose robot can not only complete some ground tasks, but also perform some aerial operations. The air-ground amphibious robot disclosed in the patent [ CN112339516A ] can climb four limbs and has a flying and high-speed gliding mode; the air-ground amphibious emergency rescue reconnaissance robot disclosed by the patent [ CN205149428U ] can complete ground crawling and air flying to perform rescue reconnaissance tasks; the patent [ CN104442248A ] discloses an air-ground amphibious robot, the main actuating mechanism of which is composed of a land device and a flying device which are fixedly connected together, and the air-ground amphibious robot has strong obstacle crossing capability and also gives consideration to flying capability. However, most land-air dual-purpose robots are either wheel-type or foot-type in land mode, which has some limitation on the land movement capability of the robot. Therefore, the invention provides the air-ground robot which has a simple structure and flexible change, can change wheel type and foot type motion modes on the land and can fly in the air, and the combination of the three motion modes enables the application occasions of the robot to be wider.
