Don't forget teams need alot more than just "technical" help. There are business things like fundraising, food, transportation, shirts, awards submissions, organization, spirit supplies (like buttons, flags, standards, signs for cheering, ect.) mascots, outreach, safety, and a lot more. Don't overlook the need for leadership in these areas or your team will end up rushing at the end and not have the quality you would like for these things.
As a rookie team it can be difficult to get the robot finished and all of these other things too. But leadership (mentor) can help to make sure these things are not forgotten and can remind the team in what time frame they need to be done.
You don't need alot of "technical" robotics skill to do these things. Look at the everyday skills you have and see how they fit. I am one of several mentors the kids call their "crafty" mentors. This is my second year mentoring. I was amazed at how well my skill-set fit into First. Even though I'm not anything close to an engineer, I found that I have a great number of skills that not only fit but made my own self confidence soar.
Maybe try not to "fit" into a mentor roll, but instead take a step back and look at where the team could use a little more leadership and help and see if you can fill that need. Try to focus on things you would enjoy showing others how to do. Or if you're the type of person who just likes to get a project and do it themselves, try to focus on things you may not have enough students to do. (The first year it's usually hard to have enough students to work on the robot and do everything else too. )
