To run the on the IFC6410

Connect to your IFC6410p board (via ssh or with a screen, mouse and keyboard)
In one terminal start the master node by running:
```
roscore
```

In another terminal run the rosserial serial node:

rosrun rosserial_python serial_node.py /dev/ttyHS2

Now you can list all the available topics by running on another terminal:
```
rostopic list
```
You can also connect to the ROS session running on the IFC6410p by doing on your computer:
```
export ROS_MASTER_URI=http://<ifc6410p-ip-address>:11311
rostopic list
```
