DRC-HUBO

Repository for DRC rubble clearing task.

Instructions to use drchubo package

1. DRC depends on DRC_msgs, so you first have to compile DRC_msgs and then drchubo
2. Currently we only support:
   • joint / pose / joint + pose animation
   • Modes no_gravity (for animation) and nominal (gravity)

To compile

1. Put DRC_msgs in a folder in $ROS_PACKAGE_PATH

2. Build DRC_msgs

   cd DRC_msgs mkdir build cd build && cmake .. make

3. Build drchubo. For this, there is one thing for you to do before doing make:

   • You have to create a link to the huboplus folder needed by Matt's code (which we use for our zmpnode executable for walking). Follow the instructions from apps/zmpnode/mattStuff/README.md to do so.
   • Now you cand do the cmake and make procedure
   • Finally, source the file setup.sh (located in drchubo) in the terminal you will use. This sets GAZEBO_PLUGIN_PATH and LD_LIBRARY_PATH to find our DRCPlugin

4. To run the rubble world example:

   • In one terminal type: roslaunch drchubo drchubo_rubble.launch
   • Press Play since we start on Pause Mode
   • Don't be surprised if the robot flies. I will change the node to start in an upper position later today
   • In another terminal type: rosrun drchubo zmpnode
   • Robot should do the same thing as the video
