Problems solved by technology

[0003] At present, most countries in the world implement the soft landing method of probes on the surface of asteroids in the "one-touch and go" method, such as the Hayabusa probe of Japan and the OSIRIS probe of the United States. The short-term contact with the asteroid surface by the probe only stayed for a few seconds, and it did not achieve a real landing.
How to make the probe quickly and stably in a microgravity environment and safely land on the surface of an asteroid with complex conditions has become a common problem in the field of deep space exploration for all countries. my country has never carried out a scientific mission to land a probe on the surface of an asteroid. At the same time, the research on this technology is almost blank

Abstract

The invention provides a leg-type asteroid surface landing buffer device based on electromagnetic damping, belonging to the technical field of deep space exploration, and in particular to a leg-type asteroid surface landing buffer device based on electromagnetic damping. Solved the problem of how the probe can safely land on the surface of a complex asteroid. It includes straight-out landing legs, servo motor controllers and the asteroid rover body shell. It is mainly used for landing buffers of asteroid probes.

Description

technical field [0001] The invention belongs to the technical field of deep space exploration, in particular to a leg-type asteroid surface landing buffer device based on electromagnetic damping. Background technique [0002] With the development of deep space exploration technology, asteroid detection has become a hot spot in the current detection of extraterrestrial celestial bodies. The safe landing of the probe on the surface of the asteroid, that is, the probe stays in a stable attitude on the star table for a period of time, is an important basis for the implementation of a number of scientific exploration missions including the return of asteroid material sampling. [0003] At present, most countries in the world implement the soft landing of probes on the surface of asteroids in a "touch and go" way, such as Japan's Hayabusa probe and the American Osiris probe. The short contact of the asteroid on the surface of the asteroid only stayed for a few seconds, and it did...
