Great question. Advanced mathematic and electronic courses while in High School will be ideal. Look at subjects that involve programming, electronic components, circuits, voltage, and physics. If these types of courses are not available at your high school, look for online STEM programs and groups that you can join. Read as many books, articles, and white papers as you can around the different fields in the robotics industry. To name a few, you have medical, manufacturing, automotive, and aerospace. Start looking at colleges that offer electrical, mechanical, or software engineering degrees with a focus on robotics. Start coding now, in Python, C++, and C for starters. Most important, share your goals with your parents and school counselor. Both will help you with your search for STEM activities, University visits and assist with ensuring you're on track in qualifying academically for college acceptance.
