We do a ton of demos, all of the time. We've had 5 demos and community service events in the 3 weeks it's been since championship. It's insane, and totally fun.

Talk to local organizations and organize demos. Some will come to you but most won't, unless you've got deep connections. Start looking for local science and technology events and ask if they would like a robot demo.

Demoing stuff like your FRC bot is nice, but having something the public can do (drive Vex robots) is the best way to get the message of robotics out IMO. It will get the most interest, and one demo will lead to more offers for demos.

Of course, demos aren't all you should do. Other outreach ideas would be volunteering at various events and functions, doing community service, etc. Starting an engineering summer day camp is a classic idea; have kids learn to build Vex robots! If you get interested people that are too young (get a list of names going), start an FLL team.

Basically, the possibilities are endless for outreach. Use the same ingenuity you worked for in building your robot to think of ways you can help the community as well as spread science and technology, and you're golden.
