Innovation Days 2009

In this page we will explain how to take good care of Chico during the 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:

machine	notes	IP address, username
Chico the robot (duh)	has a pc104 CPU in its head	10.10.1.50, icub
icubsrv Dell XPS laptop	don't worry about this machine, just keep it switched on. It contains a hard disk that gets mounted by Chico's read-only CPU at boot time	10.10.1.51, icub
chico3 Tsunami 17" laptop	we will use this machine for YARP and all demo management	10.10.1.53, icub

Below Chico's table, from top to bottom we have:

what	notes	IP address, username
iCubBrain chassis	contains two servers used for computation	10.10.1.41 (icubbrain1), 10.10.1.42 (icubbrain2), icub
Xantrex XFR 35-35	thin power supply unit, to power pc104 and some motors	-
Xantrex XFR 60-46	thick power supply unit, to power most motors	-
APC UPS	Uninterruptible power supply	-

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:

Other components

Managing 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 $ICUB_ROOT/app/$ICUB_ROBOTNAME/scripts/config.sh

[CHECK THIS]

iCubInterface

This program controls all of Chico hardware (except the cameras). In practice, all demos assume that iCubInterface is already running in the background.

To start iCubInterface, unlock the red button switch and type this on a pc104 console:

  iCubInterface --config $ICUB_ROOT/app/iCubLisboa01/conf/icubSafe.ini

and wait for all boards to answer (which takes around 1 minute); after that, you are ready to move on.

To stop iCubInterface, type ctrl+c once. Chico will thus move its limbs and head to a "parking" position. (If things don't quit gracefully, hit ctrl+c more times and be ready to hold Chico's forehead since the head may fall to the front.)

Before every demo

• Turn on icubsrv (Dell XPS laptop)
• Turn on chico3 (Tsunami 17" 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
• Start the needed YARP components with the GUI: one instance of yarpserver and all necessary instances of yarprun, one per machine

Yoga demo

• Run iCubInterface on the pc104
• On any machine, type:

  iCubDemoY3 --config /app/demoy3/fullBody.txt

Facial expressions demo

• Start the facial expression driver on the pc104:

  cd $ICUB_DIR/app/faceExpressions/scripts
  ./emotions.sh $ICUB_DIR/app/iCubLisboa01/conf

• Start the facial expression demo by typing one of these two commands on any machine:

  $ICUB_DIR/app/faceExpressions/scripts/cycle.sh

or

  yarp rpc /icub/face/emotions/in
  set all hap // full face happy
  set all sad // full face sad
  set all ang // full face angry
  set all neu // full face neutral
  set mou sur // mouth surprised
  set eli evi // eyelids evil
  set leb shy // left eyebrow shy
  set reb cun // right eyebrow cunning
  set all ta1 // mouth talking position 1 (mouth closed)
  set all ta2 // mouth talking position 2 (mouth open)

Ball following demo

This demo uses the left eye and the right arm of Chico. Assumption: left eye is running at a resolution of 320x240 pixels.

• Make sure cameras are running
• Make sure iCubInterface is running
• Run image rectifier on icubbrain1

  cd 0.icub_3D_ball_tracker
  ./0.LEFT_320x240_image_rectifier.sh

• Set left camera colour parameters and run tracker [ON icubbrain2?]

  cd 0.icub_3D_ball_tracker
  ./1.LEFT320x240.iCub_set_parameters_of_framegrabber_REALISTIC.sh
  ./2.execute_the_tracker.sh

• Start a viewer on chico3

  yarpview /viewer

• Run expression module on icubbrain1 [CHECK THIS]

  cd 0.icub_3D_ball_tracker
  ./3.execute_trackerExpressions.sh

• Run arm inverse kinematics module on icubbrain1

  cd iCub/bin
  ./iKinArmCtrl --onlyXYZ

• Connect all ports from icubbrain1. Careful: the robot will start moving after this step!

  cd 0.icub_3D_ball_tracker
  ./4.LEFT.iCub_connect_ports.sh
  ./6.connect_LeftEyeToRoot.sh

• [OPTIONAL] Read the 3D position of the ball in the root reference frame (from any machine)

  yarp read ... /icub/LeftEyeToRoot/ballPositionOut

Pausing the Ball Following demo

You can do this by disconnecting two ports (and connecting them again when you want to resume the demo).

Note that this will only stop the positions from being sent to the inverse kinematics module (and thus, almost always, it will stop the robot). The rest of the processes (e.g., the tracker) will keep running.

• Pause (from any machine)

  yarp disconnect /icub/LeftEyeToRoot/ballPositionOut /iKinArmCtrl/right_arm/xd:i

• Resume (from any machine)

  yarp connect /icub/LeftEyeToRoot/ballPositionOut /iKinArmCtrl/right_arm/xd:i

Quitting the Ball Following demo

• On icubbrain1, disconnect all ports. Careful: this will stop the robot.

  cd 0.icub_3D_ball_tracker
  ./7.disconnect_all.sh

• Quit/Kill the processes of the demo, in any order.
