"rbt file" from Scroogle:
http://www.fileinfo.com/extension/rbt: Lego MINDSTORMS NXT Program, which further searching reveals it to be a LEGO robotics kit. Wow!

Is that it? FileInfo.com says that it's a data file, rather than a graphics file. Are you looking to convert the XML code somehow?
File-Extensions.org refers to it as a miscellaneous file type.

Inkscape certainly does not directly convert SVG to RBT. I think you would have to look in your LEGO program, to learn what extensions it will accept via open or import. Then once you have that info, we can try to find an intermediary format. PDF is usually the answer, but I really have no idea. So look and see what formats that program can either open or import, and let us know, and then we can go from there

Thanks I'll work on all this and get back to you later . Any other help will be great , for me and everyone else .
