Should be possible, Martins even provides a sample in Space Shuttle Atlantis source code. And yeah, the more I think to it, the more I see it necessary to grapple small satellites and service them, would make the spacecraft quite versatile despite its limited dimensions. Maybe not something as articulated, but enough to secure things in the payload bay.

Spend the (dev) day on the docking mechanism again. Those hooks looked ugly, so I redraw them the proper way (the IDSS document has schematics for nearly any part). In fact each pair of hooks has an active and a passive one. Which makes sense, so that they can grapple the hooks on opposite docking port. Each active hook locks with a passive hook, and vice versa.



Also found a much better picture of the Shuttle docking port.



So still work to do, but it begins to look better :



The interesting thing is that you have to understand (at a basic level) how the thing works to model it properly.

Took a looot of time, but we're getting there. Still a couple of pins to add, but I have good hope to merge it with the spacecraft tomorrow. Now I see that kind of model as an investment. Animating it in Orbiter is going to be a looot of fun. But first things first.

Here we go. Should fit just right under the bay doors once the docking collar retracted. The docking tunnel will be as large as a phone booth but well, that's the idea.



Given the small size of the payload bay, the robotic arm needs 3, maybe 4 segments to be really useful.

Tried to export my mesh to Orbiter using Vlad's Blender import/export script... Well, it works. Now it will take a lot of practice to get something that really looks as it should. One thing is that Blender and Orbiter (D3D9 client) handle materials quite differently. Getting normals right is quite obvious for exterior parts such as the hull, but a bit tricky for inside. And I'll have to get into textures & UV mapping at some point, which scares me a little bit. Need to watch a bunch of tutorials

Blender's realtime OpenGL preview is close to Orbiter rendering. So use that and you should be fine.
Normals can get flipped on export. A solution is to use double sided faces.
For the VC you might have problems with Orbiter camera clipping distance. Depends on your view and if you are using multiple meshes or not.

Good luck!
