I’m a 13 year old high school student and Im mostly interested in abstract things such as theoretical physics,mathematics and philosophy . So I decided that i should focus on more realistic and practical things. I want to at least come to a-point in robotics that I can do moderately sophisticated robots. How can I start to robotics and how can I practise it . Unfortunately my family is not a wealthy one so I don’t want to load even more work to their back.
