Novel three-degree-of-freedom (three-DOF) mechanical claw

Abstract

The invention discloses a novel three-degree-of-freedom (three-DOF) mechanical claw. The novel three-DOF mechanical claw has a function of automatically catching a target; a catching execution mechanism is started to stretch, rotate and open and close the mechanical claw to execute a catching task; and after the target is caught successfully, the three-DOF mechanical claw and each execution mechanism of the three-DOF mechanical claw are locked so as to guarantee that the catching task can be successfully fulfilled. The three-DOF mechanical claw can be carried on a satellite platform to adjustand correct positions and postures under the guidance of the platform through automatically seeking, target tracking and the guidance and control of an intelligent control system, and can catch the target under a complicated environment by installing a self-contained air breathing propulsion system. The three-DOF mechanical claw has the advantages of simple structure and high reliability.

Description

technical field [0001] The invention relates to a space mechanical capture device, in particular to a novel three-degree-of-freedom mechanical gripper. Background technique [0002] As we all know, with the development of space technology, information technology and three-dimensional combat technology, various types of satellites and aircraft in the sky have effectively provided reliable information, images, communication and navigation, experimental data, etc. getting bigger. Therefore, how to invalidate in-orbit aircraft such as space exploration satellites, reconnaissance satellites, and communication satellites, or recover invalid aircraft roaming in the sky has become a key topic of scientific and technological research. Therefore, countries with strong scientific and technological strength in the world have successively launched research programs on on-orbit strike weapons (or devices). At present, more space weapons (or devices) are kinetic energy kill interceptors ...

AI Technical Summary

Problems solved by technology

The kinetic energy kill interceptor mainly uses the huge kinetic energy of non-explosive high-speed flight to destroy the target satellite through direct collision or installation of auxiliary killing devices. In peacetime or strategic confrontation stage, this attack method is very easy to be discovered by the opponent; This method will also cause a large number of debris in the sky, causing pollution to the space environment

When the space flying net captures space target satellites, it puts forward higher requirements for the space maneuvering platform and the launching mechanism of the flying net. It mainly relies on increasing the capture area of ​​the flying net to improve the capture success rate; secondly, the flying net system After launching, the flying net system becomes passive control, so the controllability is greatly reduced; finally, because launching the flying net requires a large initial speed, the possibility of rebounding of the flying net is increased, thus posing a threat to the platform
