That's exactly what I'm interested in but is that all to the topic or just a minor part?
Back in the day, people would only focus on one specific topic, say chemistry, mechanics, biology, medicine, etc. Technology was simple and basic.
But today that just doesn't happen anymore. Technology has gotten so complex that you need many experts from many unrelated fields working together to achieve the common goal. Its called interdisciplinary
Robotics is a perfect example. Cybernetics is another.
If you are interested in cybernetics, you need to study electronics, biology, psychology, neurology, and computer programming. You can't reasonably get a degree in all of these, but bio-engineering will cover a lot of important basic concepts. Then learn the rest on your own.
