For me, robots have been a part of my professional life that I would not change. Anything you have a passion for, requires time. Understanding robotics can lead to so many other things. But only you know how much time you can devote to your passion in a given month.
I saw my first TV show on robotics when I was 12. I was fascinated then and am still amazed now at new robot technology. I am fortunate in my day job that I can see robots in surgery, robots underwater and robots in school. Here are two new examples:
Chocolate - (well packaging and automation but I like chocolate)
