This article explains how to use the full-body Lisbon iCub robot (code-name: iCubLisboa01, nickname: Chico) for demos and experiments alike. We will describe the hardware setup that accompanies our iCub, how to turn things on and off, and how to run demos. For a generic description of the robot, refer to the Chico article.
An older version of this article can be found at iCub instructions/Archive.
Setup
The inventory consists of:
machine | notes | IP address, username |
---|---|---|
Chico the robot (duh) | has a pc104 CPU in its head | 10.10.1.50, icub |
iCub laptop | used to control the robot; also, it exports shared volumes (directories) to other machines of the computational cluster | 10.10.1.53, icub |
Below Chico's metal support, from top to bottom we have:
what | notes |
---|---|
Xantrex XFR 35-35 | thin power supply unit, to power pc104 and some motors. Voltage: 12.9, current: 05.0 or more |
Xantrex XFR 60-46 | thick power supply unit, to power most motors. Voltage: 40.0 (initially it is 0 - it changes when you turn the green motor switch), current: 10.0 or more |
APC UPS | uninterruptible power supply |
In a separate room there are servers that make up the iCub computational cluster, to run the bulk of algorithms and programs (inverse kinematics, vision routines, etc.).
Switching on the robot
Hardware side
- Check that the UPS is on
- Check that the iCub laptop is on, if not switch it on
- Turn on the Xantrex power supply units; make sure the voltage values are correct (see iCub_instructions#Setup)
- Check that the red emergency button is unlocked
- Turn on the green switches next to Chico
- Safety hint: first turn on the pc104 CPU switch, wait for the CPU to be on, and only then switch the motors on
- Another safety hint, after turning on motors: wait for the four purple lights on each board to turn off and become two blue lights – at this point you can continue to the next steps
Software side
- Check that the YARP Module Manager (yarpmanager) window is shown, if not run yarpmanager.sh from the laptop desktop icon and start the needed YARP components (click here for detailed instructions). The summary is:
- First, launch
yarpserver
with the 'Run' button in the Cluster tab - Then, if your application employs machines other than the laptop itself, launch the necessary
yarprun
listeners in the Entities panel: icub-laptop, pc104, icubbrain1, icubbrain2, icub-cuda
- First, launch
- The Entities tab is a GUI that manages all the necessary iCub applications
- In the iCubStartup application, launch all modules, including yarprobotinterface which is the most important one that will calibrate the robot. Just in case, make sure that the iCub is vertical before launching this software, otherwise the robot will fall down (dangerous)
- Other applications: depending on the desired application or demo, you will need to start other necessary drivers such as cameras or facial expressions
Shutting off the robot
Software side
- Stop your demo software and the cameras with the GUI; do not stop yarprobotinterface (in the iCubStartup panel) nor
yarpserver
(in the Cluster Manager window) - In the iCubStartup panel of the GUI, stop all modules, including yarprobotinterface. Chico will thus move its limbs and head to a "parking" position. (If things don't quit gracefully, stop or kill the process more times and be ready to hold Chico's chest since the head may fall to the front.)
- In the Cluster Manager window, stop the instances of
yarprun
(lower panel). It is not necessary to stopyarpserver
(upper panel), we usually keep it on
Hardware side
- Shut down the pc104 with this command in a terminal:
sudo halt
- Turn off the two green switches. Pay attention when turning off the 'Motors' switch: if yarprobotinterface was not stopped properly in the previous steps, then be ready to hold the robot when turning that switch
- Turn off the Xantrex power supply units
- Do not turn off the iCub laptop, we usually keep it on
Stopping the robot with the red emergency button
The emergency button, as the name suggests, is to be used for emergencies only. For example:
- When the robot is about to break something
- When some components make nasty noises that suggest they are going to break
Use this button with great care, as it cuts power to all motors and controllers abruptly! In particular, be ready to hold Chico, because the upper part of his body might fall upon losing power.
To start using the robot again, it is convenient to quit and restart all the software components and interfaces; refer to #Switching on the robot for that. Don't forget to unlock the red emergency button after an emergency, otherwise the program #yarprobotinterface will start but not move any joint.
Starting YARP components
- Click on the yarpmanager.sh icon on the desktop and select 'Run in Terminal' (or 'Run' if you want to suppress the optional debug information terminal)
- You will see a window divided in two parts: Cluster Management and Nodes
- In the Cluster part, click on the green 'Run yarpserver' play button. The light above the 'Stop' button will become green.
- In the Nodes part, choose all the machines in the 'Select' column, then click 'Run Selected' and wait a bit so that all machines can turn on their green 'On' light.

Other components
Many demos and programs assume that components such as cameras, the yarprobotinterface driver or the facial expression driver have been launched. To start them, first of all run the yarpmanager.sh icon. A GUI similar to this one will appear:
When you have one or more applications running, each one will have its panel (tab) and the following toolbar will be visible. Here are the most important functions (which affect all modules of the currently selected application):
yarprobotinterface
This program controls the motors and reads the robot sensors (encoders, inertial sensor, skin, force/torque). It is needed by almost all demos.
