Snatcher

This is a robot called a "snatcher" I made from instructions in a book called 

"The LEGO MINDSTORMS NXT 2.0 Discovery book" 

By Lauren's Vaulk.

Here is a front view of it with its arm up.

 This is a side view of it
with its arm down.

here its going after the red shoes in the bottom of the picture.

here its putting Doms LEGO's away for him.

The arm is the beam that grabs.

The program raises the arm then reads how far to an object in front of it with the ultra sonic sensor and then times the reading by 75 and sends it to the motor as degrees of a turn, then it approaches the object, reverses, lowers the arm, rams the object and snatches.

    

I made another program were I can touch touch sensor #2 and if touch sensor #1is pressed (when the arm is up it will be pressed.) it will go down if it is not pressed it will go up, the NXT buttons (shown as net buttons) control movement, the orange button moves it forward, the right button moves it right and the left button moves it left. 

What should the next robot be?
