Space debris large envelope capturing system with mechanical arms capable of being ejected out

The invention discloses a space debris large envelope capturing system with mechanical arms capable of being ejected out. The capturing system comprises a six-side cubic satellite body; solar panels are installed on the satellite body; buffer cushion surfaces are installed on the four sides, connected in sequence, of the satellite body; each buffer cushion surface comprises an air cushion and a force sensor arranged in the air cushion; the rigid-soft spliced mechanical arms are installed on the portions, at the two sides of the buffer cushion surfaces, of the satellite body; the force sensors are connected with the two rigid-soft spliced mechanical arms through ejection devices correspondingly; and each rigid-soft spliced mechanical arm comprises a soft part and a rigid claw, wherein the soft part is connected with the corresponding ejection device, and the rigid claw is connected to the front end of the corresponding soft part. According to the space debris large envelope capturing system with the mechanical arms capable of being ejected out, impact of fast moving debris can be borne, inclusivity of the soft parts of the rigid-soft spliced mechanical arms on sizes and shapes of the debris is higher, the rigid claws are easy to control, advantages of both rigid capturing and soft capturing are achieved, and the capturing effect is excellent.
