Innovation Days 2009

On this page we will explain how to take good care of Chico during the Ciência Viva 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 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 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 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:
