This README currently only describes how to set up the QT RehaZenter rehabilitation framework and how to get it running.
This repository contains my master thesis work for the University of Luxembourg, in collaboration with the RehaZenter facility in Kirchberg, Luxembourg. We have developed/are developing an exercise assistant that is capable of deploying and running an exercise session for heart stroke patients and elderly people on the QT Robot, completely autonomously.
Before running the application, you need to download the Qt4 and PyQt4 packages, as well as the Python API for Mysqldb. Run the following commands to do so:
sudo apt-get install libqt4-dev python-qt4 mysql-client mysql-server python-mysqldb
After installing all of the above packages, we need to perform a little change to the MySQL configuration files. Log into your QT robot, open up the /etc/mysql/mysql.conf.d/mysqld.cnf file with your favourite text editor, and comment the following line out:
bind-address = 127.0.0.1
This line makes it so that the MySQL server only listens to connections coming from the robot itself and not from the outside, thus we need to comment this line if we want to make connections from the outside (such as a client computer). Restart the MySQL server to apply the changes:
sudo service mysql restart
Next, we will create a new MySQL user that has full permissions to access the database that the application is using. Login (locally) to your database by running the following command:
mysql -u root -p
A password prompt will appear after executing the command. Enter your password and, on the MySQL interpreter, run the following SQL command:
CREATE USER 'qt_exercise_creator'@'localhost' IDENTIFIED BY 'qt_exercise_creator';
You may choose an arbitrary password if you wish, but if you do so, then make sure you change the following line in the src/gui/QTRehaZenterGUI.py file to match your updated password (line 154):
mysql_password = "*[your_password]*"
Then, create a new database called "iot" and grant your newly-created user full access rights on that database:
CREATE DATABASE iot;
GRANT ALL ON iot.* TO 'qt_exercise_creator'@'[IP_of_your_client_machine]';
Make sure that both the robot and your client machine are located on the same network, and use your machine's IP address from that same network. The SQL command above will then allow you to remotely access the database through the user "qt_exercise_creator" that we created earlier. Finally, you can run the application by first running the server instance on the robot using the following command:
roslaunch rehabilitation_framework QTExerciseCreator_ServerLauncher.launch
Then, after the server instance is running, simply launch the appropriate client launch file on your local machine by running:
roslaunch rehabilitation_framework QTExerciseCreator_GUILauncher.launch
This will bring up the GUI interface that remotely connects to the QT robot server instance, and you're free to configure your exercise setup however you like.
