You probably have to buy this book - http://www.laurensvalk.com/nxt-1_0-only/grabbot

Depending on what you want, this one might work: http://studl.es/2012/01/pincer-bot/

Actually, the one he posted the photo of is the 2.0 version - http://www.laurensvalk.com/nxt-2_0-only/the-snatcher, which is in the book http://www.amazon.com/LEGO-MINDSTORMS-N ... 866&sr=8-1

It is quite complicated, although easy enough to build with his instructions.

The snatcher is a fantastic robot. I used it as a base for my Pneumo-Snatcher

Interesting, how do you switch the pumps?

Is the secret inside the black box?

I have tried to make some sort of binary switch, to control an unlimited number of switches with one motor. But I have not succeeded at that so far.

You mean switch the valves? He used the Servo Operated Pneumatic Valve Kit from mindsensors.

Ohnoes! The valves are out of stock I wonder if you can connect a regulator to the servo controller. Insane amounts of brushless power!
