    Ubuntu 14.04 on Robotino3

  • #2
    I am just putting together a new image for Robotino based on Ubuntu 14.04. This makes installing ROS a lot easier. I rebuild everything linking to Qt5 now which is the default Qt version for Ubuntu 14.04. There still might be some bugs but I would appreciate if you could install and test the new image.

    Look into the wiki on how to install the image to Robotinos mSATA-SSD drive.

      I just installed the new image on our quite new Robotino 300.235. First impressions:
      - There are a few lines "error: file not found" followed by "please press any key to continue" right after the grub boot screen, but after a few seconds the boot process goes on.
      - The LAN network interfaces are gone. Neither eth0 nor eth0.10 are present any more. WiFi is woking as usual.

      Output from ifconfig:
      robotino@robotino:~$ ifconfig

      I will try to have a closer look today if there is time. If you want to have any log output let me know.

      It seems, that the interface naming has changed, an ifconfig -a resulted in a third device:
      em1       Link encap:Ethernet  Hardware Adresse 00:19:0f:16:db:bc

                Interrupt:20 Speicher:fe600000-fe620000
      which I could change back to eth using this information: by changing one line in /etc/default.grub
      and running sudo update-grub afterwards. Now both eth0 and eth0.10 are back.

        At every login I get this message:

          The error from the previous post can be resolved by editing ~/.profile, there is a missing = after JAVA_HOME:
          JAVA_HOME /usr/lib/jvm/java-7-openjdk-amd64/

            I just updated the robotino packages via apt-get (see log)
            upgrade robotino-api2:amd64 1.0.0 1.0.1
            upgrade robotino-config:amd64 0.9.11 1.0.0
            upgrade robotino-daemons:amd64 1.0.0 1.0.1
            upgrade robview3:amd64 3.1.0 3.1.0
            and controld3 was not starting any more. Starting it by hand resulted in
            10:44:54.657 | Not using internal gyro for odometry
            10:44:54.657 | Using external gyro for odometry/usr/local/robotino/daemons/bin/controld3: symbol lookup error: /usr/local/robotino/daemons/bin/controld3: undefined symbol: _ZN3rec8robotino3rpc6Client42set_rec_robotino_rpc_gyroscope_ext_enabledEb
            It seems that the configuration is changed to use an external gyro by default which is not present at our robots. I would suggest to make the default setting to no gyro at all.
            Changing the settings via web interface resolved the error.
