I had a similar position on 341 my senior year and found out at roughly the same time (one week before build season)

My tips:
Watch gamesense's video on how to prototype, it's life changing.

If you think someone's idea is dumb, you probably don't understand them

Try your best not to build anything without teaching someone what you're doing

Always remember, as a build team leader, you have a lot of credibility. If you are about to do something stupid, nobody is going stop you.
-watch MAR champs F2, it was my idea to try hanging on one hook

As a follow up, don't worry about getting more credibility, you already have plenty, feel free to admit mistakes or that some/most of your ideas are bad.

If you need a good idea, watch videos of old matches

Always keep an eye on the room, who is there, who isn't, who looks like they're not contributing, who looks bored, who is telling the rookies to sweep the floor while they build fancy stuff. Those are all easily solvable problems, but addressing them can really change your team for the better.

Lastly, my biggest regret, it was said before, but it can't be said enough, ask your mentors questions. Here's why:
1-It makes them feel respected
2-You two will become friends
3-They will be happy that they taught someone about robots
4-You will learn about robots
5-You are less likely to do the stupid thing that everyone was going to let you do
6-Mentors also do stupid things, being friends makes it easier to stop them
7-Newer members will see you asking questions and do the same

Making this thread was a great start to your new job. Keep it up and you'll be fine.
