You Ready to go Gung HO? A Hotshot Challenge
Now that you have completed building your robot-actors, why don't you try to take them to the next level?
Make them perform different plays. There are plenty of famous dialogs out there that could be performed by your robot-actors.
Currently your robot-actors are stationary. Try to add some servo motors and make them move their heads using an Arduino.
Connect some webcams to your computer and use Processing to record some videos of the performances from different angles.
Make your robot-actors perform a play with a real actor.
Make your robots read live input from the Web such as Twitter feeds or the news.
Your robots don't have to look like humans; make them look like zombies, aliens, animals, and so on.
