Let's Connect

For bigger spacecraft capable of executing bigger missions, some of the assembly may be done in space. Your challenge is to design a simple approach that enables components to be assembled in space.

PROJECT : O.S.D.A [Orbital Satellite Docking Approach]

Summary

Since last 40 years, Docking has never been easier.It has been observed that docking requires lot of physical effort by the astronaut as they too have to create adjustments like direction in which the satellite is moving, etc.Presenting you our project,O.S.D.A,which is a docking tool that will help astronauts connecting the satellites to the docking port without requiring human effort. Our project will be a external capsule room structure with docking ports on both its opposite sides, which will connect to the docking port. while on it's opposite side, it will have a connecting port and mechanical arms on its upper and lower portion, which will help it dragging it towards itself.

How We Addressed This Challenge

What did we develop?

Here we have developed a room like structure which will have docking ports on both its opposite sides, which will connect to the docking port. while on it's opposite side, it will have a connecting port and and mechanical arms on its upper and lower portion, which will help the satellite to by adjusting its direction so that it can be easily docked without any physical effort by the astronauts.

In this above figure,

these are the following things that we have developed:

[1] structure: we developed a structure which provides a gateway between 2 Docking ports present on it's opposite sides. it makes docking easier because it doesn't require space construction. it can be produced and deployed from earth as well.

[2] Adjustment rods: from the above given figure, those 4 straight rods which are produced in upper lower direction are the the adjustment rods. it will help docking because it will allow the robotic arms to extend and to reduce based upon the size of the satellite

[3]Robotic arms: these are the hand like mechanical tools which will help holding the satellite, which will allow it to direct the movement of the satellite.




Why is it Important?

Drawbacks of current docking mechanism: 

•The misalignment caused when placing satellite into the space center's docking port.

•The slow process with less precision adding danger to the docking process.

•Current spacecraft docking relies on active movement to close the gap between the participants, and to separate them when docking.

Effective docking mechanism is an important aspect in order to prevent accidents. A docking gone wrong is quite dangerous. If an astronaut makes a mistake while docking, there is no reset button to start the process all over again. Therefore, their accuracy has to be precise and calculated.




What does it do?

Space docking is broadly meant for two purposes:

• For sending human beings from a shuttle to a space station

• For assembling large satellites in space

Our docking mechanism, O.S.D.A [Orbital Satellite Docking Approach] will enable to connect a satellite to a space station in a more constructive way with the introduction of a specialized docking tool which extensively attach to the satellite and moves it accurately to the docking port of the space center. 

The mobility of docking tool, controlled by astronaut, which operates according to the size of the docking satellite. 

The docking tool consists of two mechanical arms attached on upper and lower side of the docking tool. The adjustment rod facilitated on each arms moves the satellite accordingly.




How does it work?

Our docking mechanism, O.S.D.A (Orbital Satellite Docking Approach), is a simple approach to proceed docking without creating much complications. 

Let's say a Satellite has to be docked into the space center.

By using the O.S.D.A docking mechanism, the difficulties faced in the conventional docking process can be minimized to a greater extend. 

The highlighter of our docking mechanism is the Adjustment rods, which can adjust mechanical arms at both upper and lower ends on the side where the satellite has to be docked within the docking tool. This adjustment rod provides the mechanical arm with support to extend or to shrink in it's length. Even though if the arriving satellite isn't accurately positioned or is tilted to any one side, these mechanical arms acts as an adjuster to place the satellite correctly to one side of its docking port.

As a result, the system will be aligned air tightly to each other

(satellite with the O.S.D.A. and O.S.D.A. with the space center's docking port).


What do we hope to Achieve?

An accurate planning is always better than calculated risks. Docking puts the arriving vehicle in control of the connection to the target. So, in order to do that accurately without complications, a precise measured movement is required to connect the objects.

The adjustment rod of the docking tool paves a well organised way throughout the docking process. The possibility of misalignment is eliminated as well as carried out systematically. 

Unlike the conventional slow process docking mechanism, the O.S.D.A is a simple approach enabling better connection towards the target saving more time and effort.

How We Developed This Project

What inspired us to choose this Challenge?

Our future in space is more flexible than ever. In order to achieve more opportunities to go beyond 'the present' and thereby accomplishing new milestones, there are some integral mechanisms that are needed renovation. 

The Docking Mechanism is one such operation that should be made more reliable and promising. Docking refers to joining of two separate free-flying space vehicles. Though it sounds simple enough, it is a very complicated process in reality. However, the importance of success matters much more.


What was our approach to developing this project?

We have gone through detailed discussion on how to manage this problem without complexity. To drag a satellite in the given context, magnetic force is not possible. Our thoughts also went for constructing vacuum log but since the space have already got large volume of vacuum, it is not possible either. Even though it has been done many times before, the docking maneuver between two objects in space is always a delicate and potentially dangerous procedure.

We pondered over a simple yet potential approach to proceed docking without much complications. And that's how we ended up creating O.S.D.A [Orbital Satellite Docking Approach].


The tools, coding language, hardware, software we used for this project:


3D Designing:


  • Blender ,
  • Auto Cad , 
  • 3D Sim Coordinates,

Video Editing:


  • Adobe Photoshop,
  • Adobe premiere pro,
  • Reaper audio editor,

Blueprint tools:


  • Geometrical tools,
  • Sketching tools,
  • Adobe scanner,


The problems and achievements the team had:

At first, It seemed to be difficult for us to find a solution for such a challenge which does not actually has much data regarding it and has been practiced from a long time. Even though there was a lot data resource about this challenge. The turning point which came to us was an idea which was attach something which can reduce human efforts on the process of docking. So then we started brainstorming about a thing that can make things easier. We found that adding a robotic arm can be the key to the solution of our challenge. then later, We figured out that it was not possible for us to prepare a solution which required in-dock construction So we prepared a model which comes out separately to connect with the docking port and the docking port on the spacecraft or the satellite.

How We Used Space Agency Data in This Project

Using the Data Resource:THEMIS Mission, CARISMA Magnetometer Network.

We got to the conclusion that magnet does not effect the orbital satellite efficiently, therefore this too became a negative factor as now we got to know that we can not use magnets in our project. So in instead, we used robotic arm produced from both upper and lower portion of the docking port.
