[zhiawei]

Hi, im a newbie when it comes to this stuff, i know it might be selfish to ask, but is it possible to have a voice chat to teach me the things you posted. It's a personal project of mine, but it be cool to have a robot in my room, i have all the necessary model printed and the electricals bought, i just don't know where to start to read or understand the things i should know of.
