Awesome!!! Job helper

This is a robot that helps a company teat its touch screens.It's called stress testing, and apparently the robot is swiping at the screen (like your finger or a stylus) and seeing how the screen holds up to the abuse. (It's also testing the built-in light sensor on the tablet's screen, but be sure to watch the video so you can see how a non-LEGO part is performing that duty.) Maybe someday mindstorms will help you too!

New System

Hey all the people that have Andriod you can now make your own apps for Mindstorms!!!
Thursday 16 December it was announced that the App Inventor for Android has integrated a palette of control functions for LEGO MINDSTORMS NXT that allows you to build your own app for your Android devices that can control your LEGO MINDSTORMS NXT robot with its motors and sensors.
At the Google headquarters in Mountainview, California, a big group of dedicated Google employees formed the 20% Robotics Task Force and spent countless hours assembling and disassembling LEGO MINDSTORMS bots to try and get the coolest designs for line following, shooting balls, and using the sensors in fun ways to demo our Android apps. COOL!!!!!! 

Cool Thing

This is a vid a a "swimmer" sorry but it has no nxt to it but i thought the movement was pretty cool.
