LEGO Sensors From Dexter Industries
Dexter Industries Header & Logo The lack of NXT Sensors in this region has led to the need to directly import and distribute these NXT Sensors from Dexter Industries. Working closely with Dexter Industries, we at Building Blocks will support users from the Asia Pacific region. Building Blocks plans to build a more integrated community for NXT Mindstorms users in this region.

    3rd Party Sensors


    Measure bending motions and make robots that mimic you.  dFlex flexible sensor measures angular displacement, or bend, of the sensor.  The sensor bends and flexes with mechanical motion.

    Use dFlex to make your robots mimic you and your fingers.  The dFlex can be mounted using mechanical means, Velcro, or 3M medical tape.  The dFlex plugs directly into your NXT and our easy to use software gets you up and running in minutes.
