New pbLua version

Monday, April 7th, 2008

Here’s a message from Ralph Hempel:

There’s a new pbLua version Beta14n that fixes a few issues in the file system, as well as adding a new function called Checksum() to sum the characters in a string.

The file system tutorial has a section at the end that shows you how to automatically run a Lua file on power up with no intervention and no console attached. That would have been handy for the UAV project…

Here are the latest new tutorials:

File System
HiTechnic IR Link
Codatex RFID Sensor
Precision Motor Control (like a servo)

Higher education with NXT

Monday, April 7th, 2008

Our forum member Linus has described a toolkit for MATLAB control of the NXT. This pointed me to this impressive student course in RWTH at Aachen. In this course students use MATLAB signal processing tools to analyze motors and sensors of NXT, and built very elaborate NXT models using MATLAB as the programming language (these robots run using the computer as a controller, not on-brick). The project statistics are impressive - over 300 students and 60 supervisors participated in Winter 07/08. Their website also has nice images and video of various projects done in the past.
