Problems solved by technology

However, the existing space service robots still have the following deficiencies: 1) the functions are fixed and cannot be adjusted
At present, space service robots are designed according to specific purposes, and the robot structure, shape, size, devices, etc. are fixed, and can only perform a few tasks, and the versatility is not strong
2) Low degree of reusability
Existing space service robots can only perform tasks set by people, resulting in a relatively low utilization rate of space service robots
If you want to complete different types of tasks, you need to develop many types of space robots, which is not only costly, but also takes a long time

Embodiment 1

[0057] Embodiment 1 The basic module 1 adopts the detection module, capture module, repair module, filling module and material module to assemble a faulty spacecraft repair robot. Faulty spacecraft repair robots can detect the cause of spacecraft failures, replace or repair damaged spacecraft cables, solar panels and even individual components, refuel the spacecraft, and make the spacecraft work again.

[0058] The specific assembly process of the faulty spacecraft repair robot is as follows:

[0059] S11. Select and assemble the basic module 1 of the faulty spacecraft repair robot. The selected basic module 1 includes a detection module, a capture module, a repair module, a filling module and a material module.

[0060] S12. Set the assembly order of the basic modules 1 according to the relative positional relationship between the basic modules 1;

[0061] Specifically, if the distance between the detection module and the capture module is relatively small, and the orbital d...

Embodiment 2

[0077] Embodiment 2 The basic module 1 uses a detection module, a capture module and a power module, and is assembled into an abandoned spacecraft transfer robot. The specific assembly and disassembly process of the abandoned spacecraft transfer robot is the same as that of the faulty spacecraft repair robot, and will not be repeated here. The abandoned spacecraft transfer robot can capture the abandoned spacecraft and drag it to the graveyard orbit, and even capture the space debris and make it deorbit, fall into the earth and burn up.

Embodiment 3

[0078]Embodiment 3 The basic module 1 is assembled into a spacecraft protection robot by using a detection module, a power module, and a protection module. The specific assembly and disassembly process of the spacecraft protection robot is the same as that of the faulty spacecraft repair robot, and will not be repeated here. When threatening space debris approaches the spacecraft to be protected, the spacecraft protection robot moves to the front of the spacecraft, and aligns the protection module with the space debris to bounce off the space debris to avoid harming the target spacecraft.

[0079] The present invention assembles the basic modules 1 with different functions into space service robots that can provide different services according to the task requirements. The basic module 1 completes a large number of tasks, has strong flexibility, high degree of reusability of the basic module 1, and low cost. The present invention adopts the method of electromagnetic force and...

Abstract

The invention relates to an outer space service robot and an assembling method and disassembling method thereof. The outer space service robot comprises at least two basic modules, and each basic module can independently operate in the outer space. Each basic module comprises a cube satellite which is provided with a plurality of functional components. A coil is mounted on the inner surface of each cube satellite and used for generating a magnetic field after currents are led in, so that approaching or separating of the basic modules is achieved. A mechanical locking device is further arrangedon the side face, provided with the coil, of each cube satellite, and the basic modules are locked through the mechanical locking devices which are coaxial with the coils. The basic modules which have different functions and independently operate are assembled into the outer space service robot capable of providing difference services according to task requirements, a large quantity of tasks canbe completed through few basic modules, flexibility is high, and the basic modules is high in reutilization rate, so that the cost is low.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and in particular relates to a space service robot and an assembly method and a disassembly method thereof. Background technique [0002] Space service robots refer to small intelligent spacecraft that operate outside large spacecraft or space stations. A space service robot is a single spacecraft. The typical mechanical device installed on the space service robot is the mechanical arm, which can intelligently complete the tasks of capturing, manufacturing, repairing, replacing and maintaining the target spacecraft under the control of the onboard computer. By providing these services, the life of satellites, spacecraft, and space stations operating in space can be extended and their functions improved. [0003] Currently, the United States Tether Unlimited is developing a space manufacturing robot called "Spider-Made". Using this robot, it is possible to flexibly weave or repair parts such...
