Yet another Wi-Fi Add-on for the Lego® Mindstorms NXT development environment has become available. You can control your Lego® Mindstorms NXT creations from a computer, or from your smartphone. In control from a few meters away, or from across the other side of the world, is a reality with the HumaRobotics WifiBlock.

The WiFiBlock is a product that has been 100% developed by HumaRobotics, the Research and development department of Generation Robots. The WiFiBlock can be programmed with NXT-G, RobotC, NXT, Lejos,etc. The sensor can be added even an Arduino compatible board. WiFiBlock communication uses an I2C protocol bus making it compatible with many development boards and various microcontrollers.

The WiFiBlock connects to  anyone of the four sensors ports of the NXT brick. The WiFiBlock exchanges commands and data 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. The WiFiBlock sensor can be used for remote control, data logging, smart home automation, or even your own NXT based wireless weather station. The sensor opens up an exciting new world of applications for you to explore. The WiFiBlock sensor allows your NXtT robot to send messages over Twitter, warn you when it detects an obstacle, or any other sensors (touch sensor, Temperature, RFID,…) is triggered.
