Demo. Essentially, show off the robot to whoever wants to see it. Community fairs, sponsors, both current and potential, libraries, schools, or anything someone else needs help doing.

Community service. As a team, do some form of community service. 1501, for example, does highway cleanup, and there are others that do this also.

FLL/FTC/VEX. Start teams at this level. It's not that hard... unless you count keeping about 10 middle-schoolers reasonably focused on a task. You just need to find/make interested students and parents. Now you have an extra outreach arm.

Turn fundraisers into outreach. For example, do a car wash where people have the option to relax outside their cars. The relaxation area would be near some of the awards that you've earned, which would be conversation starters...

Speaking of awards, try to get a place to display them... with team contact info very close by.
