Check out this geeky toy, the 18 inch voice command Dalek.

With those three words, you’ll send your 18″ Dalek into an unbelievable room defender mode. It will patrol freely around your room, searching out invaders. If it finds a person or moving object, it pursues them, asks them to identify themselves, and then waits for the correct reply. If the Dalek is not satisfied, it will proceed to “exterminate” your intruder. But that’s just the beginning – this Dalek does it all.

You can ask it about different Doctor Who characters, command it to move in a programmed (by you) pattern, play Doctor with it (a wicked “Identify the Doctor” game), and loads of other cool stuff. And if you want to control the mischief, just snap the Dalek into R/C mode and use the 4 stock remote (plus one button for speech!) to move your Dalek around.

Here’s a video of this cool toy in action.
