added stand_attachment FreeCAD model

maidenone commented 4 years ago

I noticed that you only share STL files, I want to do some modifications so i am in the process of reverse engineering the parts into FreeCAD project files. I do not know if you want this kind of contributions, but here it is just in case it of value for anyone else.

not perfect reproduction of STL, some fillets are 0.5 instead of 1 mm (FreeCAD is not great at handling fillets)

Do not merge before

[ ] link to dependent pull request

I fulfilled the following requirements

[ ] All new code is formatted according to our style guide (for C++ run clang-format, for Python, run flake8 and fix all warnings).
[ ] All new functions/classes are documented and existing documentation is updated according to changes.
[ ] No commented code from testing/debugging is kept (unless there is a good reason to keep it).

Hi, would it help if I upload the Solidworks cad files? Or is there another file format that would make it easier?

maidenone commented 4 years ago

That would be helpful, I think i can come a far way with the .STL, but i think others would appreciate the CAD files if they want to modify the project. I am trying to figure out how to start with body_structure_biped_top.STL

Solidworks requires a license, and that might be a problem for future users/contributors. It should be possible to import the SolidWorks CAD files to Fusion 360 that is "free", but sadly Fusion 360 does not run well on Linux.

I have linked the Biped Solidworks files and your FreeCAD files here: https://github.com/open-dynamic-robot-initiative/open_robot_actuator_hardware/blob/master/mechanics/biped_6dof_v1/README.md#cad-files
