Abstract
Asteroid detection is of great significance to the study of the formation of the solar system and the origin of life. However, there are many types of asteroids, and they are far away from the earth, and the understanding of their various characteristics is not clear, which brings huge technical challenges to the landing and attachment of star catalogs. At present, the world is mainly based on surround, overflight, and short-term contact detection, and long-term attachment detection has not yet been realized. In order to solve the long-term attachment detection requirements of asteroids, focusing on the geological characteristics of various types of stars, this paper proposes a new type of asteroid attachment mechanism based on the beetle bionic theory, which can realize intelligent and flexible attachment and has strong adaptability. Around this design, this paper analyzes the mechanism of adhesion and realizes the adaptive matching of unascertained terrain landing point adhesion. On this basis, a prototype of the asteroid landing attachment mechanism was developed and verified by experiments. The experiment proved that the mechanism has strong multiterrain matching ability and can obtain an adhesion force of not less than 36 N on ordinary concrete ground.
Highlights
The detection of small celestial bodies is an important part of the field of deep space exploration and one of the most active technical fields in the development of space technology
The “General Implementation Plan for my country’s Deep Space Exploration Before 2030” issued by the National Defense Science and Industry Bureau clearly includes the small celestial body detection mission, and it is proposed that Mars sampling return, asteroid exploration, and Jupiter system exploration should be realized around 2030
Space powers such as the United States, Europe, and Japan have achieved a series of results in asteroid detection [3,4,5,6,7]
Summary
The detection of small celestial bodies is an important part of the field of deep space exploration and one of the most active technical fields in the development of space technology. The “General Implementation Plan for my country’s Deep Space Exploration Before 2030” issued by the National Defense Science and Industry Bureau clearly includes the small celestial body detection mission, and it is proposed that Mars sampling return, asteroid exploration, and Jupiter system exploration should be realized around 2030. From the perspective of the development of deep space exploration technology abroad, the detection of planets and small celestial bodies mainly adopts methods such as short-range leap, surround detection, and surface landing attachment survey [8,9,10,11,12,13,14,15,16,17]. Scholars have proposed various attachment techniques such as anchoring, grasping, dry adhesion, or drilling, but how to construct an attachment system with high reliability, high adaptability, and intelligent attachment is urgently needed to carry out related research
