Space reconfigurable truss type capturing mechanism and capturing method thereof

Abstract

The invention provides a space reconfigurable truss type capturing mechanism and a capturing method thereof.The space reconfigurable truss type capturing mechanism comprises a base and two reconfigurable truss type capturing fingers, and each reconfigurable truss type capturing finger comprises a butt joint plug truss unit, a butt joint connector truss unit, a plurality of modular extensible trussunits and a plurality of linear driving devices; the butt joint plug truss unit, the modular extensible truss units and the butt joint connector truss unit of each reconfigurable truss type capturingfinger are connected in sequence, and a linear driving device is connected between every two adjacent truss units of each reconfigurable truss type capturing finger. Butt joint or separation betweenthe capture fingers and the base and butt joint or separation between the two fingers can be achieved, and capture can be completed by selecting a two-finger cooperation mode or a mode that the two fingers are in butt joint to form a lengthened finger according to different requirements of capture tasks; butt joint expansion is achieved, the structure is simple, the weight is light, the capturingspace is large, and adaptability to captured objects is good.

Description

technical field [0001] The invention belongs to the technical field of space robots, and in particular relates to a space reconfigurable truss type capture mechanism and a capture method thereof. Background technique [0002] With the development of aerospace technology, the frequency of space exploration activities has increased year by year, and more and more spacecraft are performing tasks in orbit. However, due to its own failure, exhaustion of fuel or collision, the orbiting spacecraft will fail and become space junk, threatening the safety of other spacecraft and astronauts. The use of on-orbit capture devices to capture and reuse failed spacecraft is of great significance to extend the service life of spacecraft, reduce costs and maintain the safety of the space environment. Therefore, from a long-term development perspective, the capture device for on-orbit service will become an indispensable application technology in my country's future space exploration. [0003...
