HiTechnic Servo Controller
Wednesday, November 12th, 2008
As most of you know, FRC announced they will move from Vex to using LEGO NXT. For this, the ‘TETRIX’ system was invented. It is an all metal robotic system, which uses the LEGO NXT as the ‘brain’. It can also be cross-built with LEGO Technic parts. The above image, taken from this LEGO Educational store page shows the new HiTechnic servo motor controller for TETRIX. Since TETRIX can couple to LEGO Technic, this controller should be useful for “regular” NXT users too. Together with the new DC controller (see here) these may revolutionize the number of motors one can use per NXT. Each servo controller can attach to 6 R/C servos, and each DC controller to 2 DC motors. Up to 4 Servo/DC controllers can be daisy-chained to one NT port. A simple calculations gives a maximum of 6×4x4=96 servos per NXT (this will need carrying lots of batteries, mind you!).

LabVIEW for LEGO MINDSTORMS NXT book
Wednesday, November 12th, 2008
NTS released Michael Gasperi new book - programming LMS with LabView. Since I was the technical editor, I promise anyone interested in this field will find it very interesting. It covers LabView 8.5 (but the toolkit works with LV 7.1+) and describes basic programming as it teaches the NXT toolkit step-by-step.
