ARM Questions
Q1: Why isn't my robot displaying properly?
If only part of your robot is being rendered, or triangles do not appear properly, it is possible that the proprietary hardware drivers are not being used for rendering images. If you are using an nvidia card, go to the System->Administration->Hardware Drivers menu item from the desktop, and enable the proprietary hardware driver for the graphics card. Reboot the machine, and try again.
Q2: How do I run stereo on the Bumblebee images?
You can use ROS's built in stereo routine. Some stereo parameters are set by one of the launch files, and the following command should generate good quality stereo data.
ROS_NAMESPACE=BB2 rosrun stereo_image_proc stereo_image_proc __name:=proc
Q3: Why doesn't autocomplete on ROS commands work anymore?
ROS changed the name of their default setup script from setup.bash to setup.sh If you installed ROS before mid-January 2011, and then updated your ROS install through the update manager or some other method, then you need to edit your ~/.bashrc file to replace /opt/ros/cturtle/setup.sh with /opt/ros/cturtle/setup.bash
