/opt/ros/indigo Common errors: The compilation process compiles more than 180 package and installs it in the/opt/ros/indigo directory, often reporting ' collada_parser ', ' collada_urdf ', ' Rviz ', ' Visualization_ Tutorials ', ' rqt_robot_plugins/rqt_rviz ' these packets are faulty and the installation is interrupted. The solution is to remove the packages from the directory ~/ROS_CATKIN_WS/SRC directory and recompile the entire Ros. Finally, a separate workspace is created and the packages a

When you log on to Raspberry Pi and open a terminal window, or you replace the graphic user interface and start directly to command line mode, you will start in the home directory. If your user name is Pi, the path is/Home/PI. This is where the user saves the user's own files, including the folder desktop where the us
