Here's an interesting guest blog entry by Hans Odenthal from Netherlands:
A group of ten enthusiastic colleagues of the Dutch technical software company Sioux Embedded Systems are working in their spare time on a fully automated LEGO® train, called Sioux .NET on Track.
The power functions train is controlled by a LEGO® NXT, the Hi-Technic IR Link sensor and Codatex RFID sensor. The LEGO® NXT bricks themselves are remotely controlled by a PC, using an application written in C#.
The first functional protype has been on display in 2012 at LEGO WORLD in Zwolle (Netherlands).
After that, a new target has been set up for LEGO WORLD 2013, involving improved features like automatic switches and much more.
Some impressive numbers:
- a total of appr. 2000 hours have been spent for building and programming
- six NXT bricks are required for control
- two trains
- three switches
- PUI (Physical User Interface, a new term to indicate the LEGO® Buttons)
- Codatex RFID tags for train detection
The work in progress can be found at the group's blog and Youtube channel.
