Oedipus Rex is a good play. What I found most interesting was the prophecy and the illusion of control. Despite knowing what would happen (because the Oracle is never wrong) Jocasta and Laius tried to divert fate, and prevent Oedipus from fulfilling the prophecy. In doing so, they caused the outcome (of course). However, Jocasta killed herself when she found out, and Oedipus blinded himself. Was this their punishment for tempting fate? Did they feel responsible for the outcome? Do they really have free will?
You can control a Mecanum drive using one of two methods in RobotDrive. Here's a link to one of them. You really just need to plug in joystick values, and set gyroAngle to 0 if you are doing robot-centric control.
