MSL library soruce + PQP source: Media:MSL.zip compiled on Ubuntu 8.10 with gcc 4.3.2
Software Installation [TODO: complete]
This guide is tested on Ubuntu 8.10, 9.04 and Xubuntu 8.10. GCC version in 4.3.
- Install the following packages:
If you want you can cut and paste this command line: sudo apt-get install ...
- Download this file: [TODO], which contains ARToolKitPlus Libraries
- unpack it in /opt folder
- go into /opt/ARToolKitPlus_2.1.1
- export ARTKP=/opt/ARToolKitPlus_2.1.1
- sudo make install
- download lurch-control.tar.gz
- extract it in your home folder
- make cleanall
- make ROBOT=wheelchair MODULE=misc
- make ROBOT=wheelchair
- cd wheelchair
- ln -s ../logExtract.sh ./
- ln -s ../run.sh ./
- download lurch-wheelchair-standalone.tar.gz
- extract it in your home folder
- go into lurch-wheelchair-standalone/config
- edit config.ini
- replace line with hostname=airlab-blackbox with hostname=<yourhostname>
- edit agent.ini
- find and replace all "airlab-blackbox" with <yourhostname>
- download the server for simulation (you need sun-java6-jdk installed and Eclipse is suggested)
- from lurch-wheelchair-standalone
- sudo ./run.sh

PCBrick-03 and PCBrick-05 feature Xubuntu Linux 7.10, Xfce Window Manager, Openchrome graphics drivers and eGalax touchscreen drivers v1.08.1227 (Drivers here). The touchscreen is configured and calibrated on both machines, hence it can be used with either one or the other indifferently.
We are currently designing a new electronic main board for the wheelchair.
The idea is to base the whole system on a CANbus, allowing a complete modularization of the on-board electronics.
- Try a different sw architecture, now we are examinating orocos 
- Integrate Marco Assini's thesis (RRT planning) with current release
- Develop an improved navigation system Read more on this topics here...
