Planet surface mechanical arm sampling device

Abstract

The invention belongs to the field of spatial sampling robot engineering and particularly relates to a planet surface mechanical arm sampling device. The planet surface mechanical arm sampling device comprises a sample saving box, a sampling mechanical arm system and a sample saving system, one end of the sampling mechanical arm system is connected onto the sample saving box through a joint, and the other end of the sampling mechanical arm system is connected with an opening-and-closing type bucket through an opening-and-closing type shoveling mechanism, the sample saving system is installed in the sample saving box, an opening is formed on the sample saving box, and samples collected by the bucket are placed in a sample receiving area of the sample saving system through the opening for saving. The planet surface mechanical arm sampling device is light in structure weight and flexible in operation, can resist to the spatial electromagnetic environment and extreme high-and-low temperature conditions on a planet surface in an application process and can adapt to wide engineering application environment and a big scope. The planet surface mechanical arm sampling device can be used for conveniently colleting objects at any position of a sphere with a mechanical arm installation base to serve as an original point and the overall length of the sampling mechanical arm system to serve as the centre of a circle, and the planet surface mechanical arm sampling device has a plurality of superiorities on sample collection work under serious conditions.

Description

technical field [0001] The invention belongs to the field of space sampling robot engineering, in particular to a planet surface mechanical arm sampling device. Background technique [0002] Human beings have never stopped exploring the universe. At present, major developed countries in the world are doing a lot of research and development of aerospace technology, including the ongoing Mars exploration project in the United States, the space station project jointly carried out by major European countries, and the lunar exploration projects in Japan, India and other countries. During planetary surface exploration operations, the robotic arm, as a payload for operating scientific instruments, has been studied by many institutions at home and abroad, and is widely used in planetary exploration operations to complete the manipulation of payloads, such as spectrometers, microscopic imagers, shovels, etc. . [0003] And our country's lunar exploration program is gradually unfold...

AI Technical Summary

Problems solved by technology

The lunar surface environment in the universe is extremely complex, among which there are harsh conditions such as temperature and space radiation on the lunar surface, which affect the use of lunar exploration and sampling equipment. The main negative effects are: reduced sensitivity of the optical system, blurred vision, reading errors, seal failure, Mechanism blockage, material wear, thermal control system failure, etc.

[0004] At present, the robotic arms developed at home and abroad are all general-purpose robotic arms installed on the planetary landing vehicle. Usually, a large number of scientific detection and acquisition instruments are installed at the end of the robotic arm, which makes the volume and quality of the robotic arm relatively large. The requirements for weight and structure are relatively large. It is a relatively heavy burden for demanding aerospace projects
