And if you're in high school, join a First Robotics team. (In First Robotics, teams build a moderately large robot that can zip around a field, grabbing things and shooting balls for instance. It's like a competitive sport but with robots competing. The robots are controlled by drivers, but can also act autonomously for more points. The task is different each year, with sub-tasks of varying levels of difficulty, so teams with widely different skill levels can take part: some robots are very simple while others are amazingly complicated. It's a great way for high schoolers to learn engineering skills, anything from programming to mechanical engineering.)

I would say for starting a first robotics lego league is going to be easier to access because they build a smaller robot out of legos, plus the "season" starts in the Fall vs. January for First robotics league.

I've coached a First team that has qualified to go to worlds the last four years and been on the Einstein field once in that time. I think you'd learn a few things - robots are built to solve problems and the most technically complex and advanced robots don't always solve problem better than simple elegant designs. - Robots involve multiple skills and usually get built by teams where members are specialists in specific fields. Some people will understand all of the robot sub systems but

I couldn't agree more. FIRST is an excellent organization to get involved with. Even if you don't have specialities which directly align with the needs of a team, most will not turn you away (especially if you demonstrate passion).

Just a few thoughts about starting a team and/or volunteering:

Starting a FIRST Robotics Competition (FRC) team is not for the feint-of-heart and requires significant time and money investment. This is the sort of endeavor you try when you're either retired or have a group of other dedicated volunteers willing to help you build the team over multiple seasons. If you spend a year or two mentoring/volunteering for a well-established team, you'll get a good sense of what you're getting into. FRC is a bit hardcore.

If no FRC teams exist nearby, FIRST Lego League (FLL) is a good entrypoint, but may not be technical enough for an adult interested in using FIRST to gain exposure to robotics. (It is plenty satisfying to mentor these teams, but Mindstorms can be somewhat limiting.) These are geared toward using Lego Mindstorms for learning robot concepts.

A good middle ground (for exposure to more practical robotics) would be volunteering with a FIRST Tech Challenge (FTC) team. It's the middle ground between FLL and FRC and is _doable_ for a single, dedicated, passionate adult to start (though I'd strongly recommend finding another volunteer to pursue this with).

If getting involved with a team is not an option, seek out nearby FIRST events that you can volunteer at. Many competition events need volunteers and you'll get a chance to interact with local teams and find plenty of opportunities to play with robots.
