Asteroid microgravity surface touring mechanism

Abstract

An asteroid microgravity surface touring mechanism comprises claw attachment devices (5), rotary drill devices (6) and creeping devices (7), and the claw attachment devices (5), the rotary drill devices (6) and the creeping devices (7) are mounted on a lander body (4). The creeping devices (7) are 6-degree-of-freedom mechanism arms, each group of the creeping devices include three creeping devices at intervals, and two groups of the creeping devices are alternate in attachment and movement to realize turning and integral translation movement of the touring mechanism. The claw attachment devices (5) are in annular array layout on the basis of bionic beetle microtrichia seizing attachment technology and used for providing ground normal attachment force to realize attachment to rough and hard asteroid surfaces. The rotary drill devices (6) are mounted at tail ends of the mechanical arms respectively, and a group of the rotary drill devices (6) provide the ground normal attachment force by means of inward oblique rotating. The asteroid microgravity surface touring mechanism has the advantage that reliable attachment of asteroid probes and continuous mobile survey of multiple target points are realized under uncertain conditions of asteroid microgravity environments and surface terrain geological characteristics.

Description

technical field [0001] This patent belongs to the technical field of microgravity surface inspection for asteroid landing detection, and relates to a microgravity surface inspection system mechanism based on bionic crawling and grasping technology. Background technique [0002] my country has already achieved world-renowned achievements in lunar exploration, and the exploration of Mars and asteroids is becoming a research hotspot. As the most effective detection method, surface landing patrol detection is the main technical means for planetary and asteroid detection. A variety of lunar and planetary detection patrol platforms have been developed at home and abroad, but asteroid detection mostly uses observation methods. Currently, asteroid surface Only Japan's Hayabusa probe and ESA's Rosetta Philae lander were used for sampling and detection, and only the latter achieved real landing and in-position detection. However, due to the anchor attachment method, the sampling can o...

Problems solved by technology

[0003] The surface detection of asteroids is more difficult than that of the moon and planets, mainly because of the microgravity environment and unstructured surface structure on the surface, which makes the probe very vulnerable to disturbance and drift after landing. technical challenges, there is currently no recognized feasible technical approach
