LEGO.com MINDSTORMS Overview

Name: Alpha Rex

Robot Type: Humanoid

What this robot can do:
Alpha Rex performs tasks that only the most sophisticated robots can do... Walk on two legs like a real person! With built in rotation sensors on the two Servo Motors powering his legs, and an Ultrasonic Sensor enabling Alpha Rex to see, you can program Alpha Rex to go where you want with precision!

He Sees! (With an Ultrasonic Sensor)
He Hears! (With a Sound Sensor)
He Talks! (With a built-in Speaker on the NXT brick and sounds from the NXT Software)
He Walks! (With two Servo Motors)
He Feels! (With Touch and Light Sensors)

See how easy it is to program AlphaRex to walk and have his "Heart Beat" on the NXT Display!
This simple program makes use of simultaneous tasks on two Sequence Beams. Alpha Rex’s heart beats on one task, while his legs are powered to move on the other.
