We have done the pet vex bot before that follows a green light and that was a big hit. The other thing you can do is take 2 vex bots with and play bummper bot. You put a bumper on each one that is programmed to disable the bot for 10 sec. THen you set out a small field and let the conventionairs play with them. See who can knock each other out. That way they get thier hands on the robots.
