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.
