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

    Now your robots can know exactly where in the world they are! The Dexter Industries dGPS Sensor provides GPS coordinate information to your robot and calculates navigation information. The sensor provides latitude, longitude, time, speed and heading to your robot. It also has powerful navigational calculators that can be used to navigate to target coordinates.

    The Dexter Industries GPS Sensor can be used for any robot that needs to know where it is or where it's going. You can do everything from track road trips on Google Maps to build a satellite-guided robot.

    The dGPS hooks directly into any of the four sensor ports on the NXT and can be programmed in NXT-G, RobotC, and Lejos.
