I've worked with LEDs and things before, using Instructables, but don't know how to use formulas related to that. But now I want to do a large scaled project, by leaping off the bridge, and having no clue what I'm doing. I'd like to build a robotic human head, a women, that uses a webcam for face recognition, a microphone for speech recognition, and a robotic jaw, to move to the speech. SO, first, what programs can I use for the face recognition, and how can I use my computer for this, with out needing to use my computer as a permanent piece (A.K.A: A plug in, so I can use her when I feel like.) Two, how can I use the webcam for face recognition, programs. And three, not entirely needed, is a moving jaw, to match the rhythm of speech, if possible. BUT, I really DON'T want to spend money on those programs. A lot to ask, but can someone answer with a detailed explanation. Please don't show me this link: https://www.instructables.com/id/Making-an-Android-For-less-than-30/ No offence to the author, but I couldn't understand how it works, because it lacked detail on programs, and ect.
