WIFI for Mindstorms NXT

Dexter Industries brings Wifi to Lego Mindstorms NXT.

We’ve built our first prototype and we’re shipping them out to our beta-testers and collaborators.  The hardware is done, and over the next few weeks we’ll be working to develop some killer software applications that will bring all the power of the internet and wifi to Lego Mindstorms NXT

Wifi and the internet come to the Mindstorms NXT.

Dexter Industries new Wifi sensor for the Mindstorm NXT.

Coming very, very soon!

Got an idea?  Want one now without the software?  Contact us!

    Is this anything like the samantha module used in First Tech Challenge?

    • Administrator April 9, 2011

      We’re not too familiar with the Samantha modules but there are a few fundamental differences. This will connect to Port 4 rather than the USB port of the NXT. It also directly connects to the NXT with no PIC in between the module and the NXT, and very little configuration.

  2. Hi Guys! This one’s looking very promising… Can hardly wait to get my hands on one.

    Can you set up a NXT to work as a Server?

    • Administrator April 9, 2011

      Hey Ray, we haven’t developed all the software for it, but in theory it should be possible!

    Will this sensor allow users to turn on or turn off NXT remotely via wifi connection? 😀

    • Administrator April 9, 2011

      Probably not. But maybe some bright engineer can figure this out!

  4. That is very, very cool!

    An army of twittering NXTs looms over the horizon 🙂

    Can’t wait!

    Very cool!!
    This product can I buy from?

    I can’t wait anymore.
    As I know, you transfer and receive data using HTTP method?
    Can you give me some sample code in C# or VB.NET?

    • Administrator June 19, 2011

      We’re not going to officially release it until we have, at least, one or two good examples in RobotC out there. However, if you’re willing to forgo the examples and want to work on it, you can buy the sensor here: Wifi Sensor

    So this seems a little bit unclear to me. Once your nxt is connected to the internet using your wifi sensor, can you then send direct commands to the nxt through the wifi sensor, or do you need to have a program running on the nxt to do anything useful?

    • Administrator July 30, 2011


      We’re in the process of trying to simplify some of the software. Ideally you would be able to either control it through the internet via direct commands, similar to what Xander did, or setup a more advanced way of communicating and getting data. You generally have to have a program running on the NXT though for it to do anything useful, whether you’re using our sensors or anyone else’s.

    All, just wanted you to know that the sensor has been released and over the next week we’ll be publishing some examples and walk-throughs. Enjoy our Wifi week . . . it’s been a long time coming. Thanks for your patience!!
