NXT Optimus Prime

[Cbotics]

A walking and talking LEGO Optimus Prime that I built last year. He also attacks when he detects an object with his ultrasonic sensor. See video of him in action on Youtube:

@ Cbotics: Welcome to Eurobricks! Your Optimus Prime autobot has ninja-like flailing arms that can dice up any Decepticon!

Welcome to EB!

I really like the flailing arms, next you have to make it transform

Thank you both. I started off just making a walking robot, so the flailing arms were the result of thinking of something cool that I could do with my 1 remaining motor.
