Normally more advanced discussion centers around specific products, programming languages and/or software. For example if you are working on SLAM using specific hardware, you might take a look at that company’s forum / community, especially since the manufacturer should be replying as well. When it comes to general (advanced) Q&A it’s often hard to get answers without having done a very similar setup. One approach would be to scour the interwebs and find similar projects and attempt to contact the creator(s). Let’s Make Robots has some fairly advanced robots and many members of the community have engineering / technical backgrounds.
