ICub laptop

This laptop is used to control the iCub robot.

Toshiba Qosmio X70 17" iCub laptop.

Note: this laptop replaces Chico3, which was used during 2009-2014.

Specifications

• processor: 4 x i7-4700MQ @ 2.40-3.40 GHz
• memory: 32GB
• graphics card: Nvidia GeForce GTX 770M with CUDA and 3072MB of memory; onboard card HD 4600

Setup

Ubuntu LTS Desktop, 64-bit. Computer name: icub-laptop.

Operating system installation

In the Windows 8 preferences, configure the power button to really turn off the machine (as opposed to suspend). In the BIOS, activate CSM instead of UEFI. Now it is possible to boot from a Linux DVD.

Network

See also VisLab machines configuration#Network_configuration.

address 10.10.1.53
netmask 255.255.255.0
gateway 10.10.1.254
dns 10.0.0.1, 10.0.0.2

NFS

These NFS filesystems are exported according to /etc/exports:

/exports/code          10.10.1.0/255.255.255.0(rw,sync,no_root_squash,no_subtree_check)
/exports/local_yarp    10.10.1.0/255.255.255.0(rw,sync,no_root_squash,no_subtree_check)

The NFS filesystems are mounted as defined in /etc/fstab:

icub-laptop:/exports/code        /usr/local/src/robot            nfs    _netdev,auto,hard,intr    0    0
icub-laptop:/exports/local_yarp  /home/icub/.local/share/yarp    nfs    _netdev,auto,hard,intr    0    0

Successful mounting shows:

$ mount
...
icub-laptop:/exports/code on /usr/local/src/robot type nfs4 (rw,relatime,vers=4,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.10.1.50,minorversion=0,local_lock=none,addr=10.10.1.53,_netdev)
icub-laptop:/exports/local_yarp on /home/icub/.local/share/yarp type nfs4 (rw,relatime,vers=4,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.10.1.50,minorversion=0,local_lock=none,addr=10.10.1.53,_netdev)

If automatic mounting at boot time fails, mount the volumes manually:

sudo mount icub-laptop:/exports/code        /usr/local/src/robot           -t nfs   -o _netdev,auto,hard,intr
sudo mount icub-laptop:/exports/local_yarp  /home/icub/.local/share/yarp   -t nfs   -o _netdev,auto,hard,intr

Open issues

• brightness: fn+F2 does not work, fn+F3 does not work and hibernates the machine

• shutdown does not work

Customization

Passwordless connections

First, generate a key as follows. You only need to it once; use default choices:

ssh-keygen -t rsa

Then, copy the key to each machine you want to connect to, e.g., for pc104 do the following:

ssh-copy-id -i /home/icub/.ssh/id_rsa.pub icub@pc104

Launcher icons

Install gnome-panel then use gnome-desktop-item-edit to create/edit launcher icons on the Desktop.

For example, to create a launcher for icub-cluster.py, do

gnome-desktop-item-edit ~/Desktop/cluster-manager.desktop

and select:

Type: Application // <-- runs the command without showing any terminal; use "Application in Terminal" to show it
Name: icub-cluster // <-- put your preferred icon name here
Command: icub-cluster.py vislab-cluster.xml
Comment: Launch iCub cluster manager (yarpserver and yarprun)
