| In this page we will explain how to take good care of Chico during the [http://www.innovationdays.eu Innovation Days 2009] exhibition that takes place in the Feira Internacional de Lisboa from 18 to 20 June 2009.

| == Setup ==
| |
| | |
| The demo inventory consists of:
| |
| * '''Chico''' the robot (duh), which has a [[pc104]] CPU (10.10.1.50, username icub) in its head.
| |
| * '''icubsrv''' Dell XPS laptop: 10.10.1.51, username icub. No need to use or modify this machine, it contains a hard disk drive that gets mounted by Chico's read-only pc104 CPU at boot time. Don't worry about this machine, just keep it switched on.
| |
| * '''[[Chico3 laptop machine configuration|chico3]]''' Tsunami 17" laptop, 10.10.1.53, username icub. We will use this machine for YARP and all demo management.
| |
| | |
| Below Chico's table, looking from bottom to top, we have:
| |
| * APC UPS (Uninterruptible power supply)
| |
| * Xantrex XFR 60-46 power supply unit (the thick one) for motors
| |
| * Xantrex XFR 35-35 power supply unit (the thin one) for [[pc104]] and other motors
| |
| * '''[[iCubBrain server configuration|iCubBrain]]''' chassis containing two servers to be used for computation: '''icubbrain1''' (10.10.1.41, usual username) and '''icubbrain2''' (10.10.1.42)
| |
| | |
| == Starting YARP components ==
| |
| | |
| Launch the graphical '''[[Cluster Management in VisLab|Cluster Manager]]''' application on the chico3 laptop, by typing this in a terminal:
| |
| | |
| cd $ICUB_ROOT/app/default/scripts
| |
| ./icub-cluster.py $ICUB_ROOT/app/$ICUB_ROBOTNAME/scripts/vislab-cluster.xml
| |
| | |
| === yarpserver ===
| |
| | |
| Click 'Run' to start yarpserver on chico3. The light above the 'Stop' button will become green.
| |
| | |
| === yarprun ===
| |
| | |
| Now we are ready to start 'yarprun' on all the machines we need (necessary for the distributed YARP modules that make up a demo to communicate with one another). In the 'Select' column, make sure that only the following machines are selected with a red light:
| |
| * chico3
| |
| * pc104
| |
| * icubbrain1
| |
| | |
| Click 'Run Selected' and wait a bit so that all machines can turn on their green 'On' light. The [[pc104]] can be slow and, sometimes, unpredictable.
| |
| | |
| Do all the selected machines have their 'On/Off' switch green by now? If so, proceed to the next step. If not, click on 'Check All' and see if we have a green light from the [[pc104]] now. You should see something like this:

| |
| | |
| == Cameras ==
| |
| | |
| Open a chico3 console and type:
| |
| cd $ICUB_ROOT/app/default/scripts
| |
| ./cameras start
| |
| | |
| Sometimes we need to manually establish these connections in order for images to display:
| |
| yarp connect /icub/cam/right /icub/view/right
| |
| yarp connect /icub/cam/left /icub/view/left
| |
| | |
| To turn off the cameras:
| |
| ./cameras stop
| |
| | |
| To change the size of images:
| |
| nano -w $ICUB_ROOT/app/default/scripts/config.sh
| |
| | |
| == Running a demo ==
| |
| | |
| * Turn on icubsrv (Dell XPS laptop)
| |
| * Turn on chico3 (Ts" laptop), which we will use to actually control the demos
| |
| * Turn on the Chico's Xantrex power supply units
| |
| * Turn on the green switches behind Chico
| |
| * [http://mediawiki.isr.ist.utl.pt/wiki/Innovation_Days_2009#Starting_YARP_components Start the needed YARP components] with the GUI: one instance of yarpserver and all necessary instances of yarprun, one per machine
