WifiBlock device for Lego Mindstorms NXT

How does the WifiBlock NXT robot work?

Connected to one of the four sensors ports of your NXT brick, the WifiBlock receives orders from your robot and relays them over an IP network using its wireless connection. The WifiBlock exchanges data with any device connected to your local network (computer, smartphone, and tablet) or with servers on Internet. Remote control, robot sensors data logging, smart home prototype or even your own NXT based wireless weather station, it’s an exciting new world of applications opening up. Your NXtT robot can send messages over Twitter, warn you when it detects an obstacle of when one of his sensors (touch sensor, RFID,…) is triggered.

Exciting robotics projects for everyone!
