Problems during installation and learn
% install orocos
- install ros
- install the package: sudo apt-get install ros-indigo-rtt-ros-integration
- install orocos toolchain from github. https://github.com/orocos/rtt_ros_integration
should refer to the problem file instead of this file
- To compile orocos component, change "add_executable" to "orocos_component" in the CMakeLists.txt. Actually, it seems that there are multiple methods to compile orocos package. To check later.
