Is this ready for merging?

I think the PR2 part should be split from ROS package `gps_agent_pkg`, then package `gps_agent_pkg` will be robot-agnostic, at least we don't need to compile the `gps_agent_pkg` with PR2 ROS...

@wtokumaru thanks for sharing your thoughts. Are there some better algorithms beyond this GPS for such tasks? I hope to find a replacement.

unknown dynamics and need fewer samples, more efficient sample.

@sherm1 Thanks for your reply. I find that the codes of Gazebo are copied over from this example, and [here](https://bitbucket.org/osrf/gazebo/src/f34784b7994ade9758440d7f65bd6c4e295dcc9e/gazebo/physics/simbody/SimbodyPhysics.cc#lines-923) has the same mistake. I think this example is the...

I try to fix it. But which one is the appropriate method for this, `Constraint::Weld` or `MobilizedBody::Weld`? I'm not familiar with the simbody terminology and API. Any more help about...

@ipa-mdl What's the status of this PR? We have the same issue, is there a solution for this issue? Can ros_canopen support multiple-pdos mapping now?

@ipa-mdl actually this PR only check the mapping and don't make ros_canopen work with this situation. If you have solutions to make doubled PDOs work with ros_canopen, we can test...

I hope to use the `grl` in ROS project, but just using find package grl is not enough. ``` find_package(grl) ``` I get the following errors from cmake: ``` undefined...
