Overview

This page explains how to configure your workstation to control the Mini-Lab

First you need to connect the workstation to your Mini-Lab's WIFI that should look like ML-201412-006
Then you need to know what your IP is. To do so you can use the command "ifconfig"
```
         $ ifconfig
```
- You should see your adress in wlan topic after "inet adr:"
And what your robot's IP is. The address starts with 192.168.0.2 and finishes with your model's number, in our case ML-201412-006. So in this example the robot address is 192.168.0.206.
You can ping this address to be sure everything is going well so far.
Now that you know the IPs, we can configure the ros parameters. Open a new terminal and run the following commands but don't forget to replace by your addresses:

         $ echo "export ROS_MASTER_URI=http://192.168.0.206:11311" >> ~/.bashrc
         $ echo "export ROS_IP=192.168.0.100" >> ~/.bashrc

In this example the MASTER is the Mini-Lab (192.168.0.206) and the workstation IP is 192.168.0.100

To have access to the Mini-Lab's topics you need run the following commands:
```
         $ ssh user@192.168.0.206
```
- Don't forget to replace by your Mini-Lab's IP
- This command start a ssh communication with the Mini-Lab

         $ roslaunch minilab_launch minilab_driver_hokuyo.launch

If you run the command "$ rostopic list" in a new terminal you should see all the topics published by your Mini-Lab.
