i have no idea to solve this.
thanks ,Ryo.
PS roscontrollers package cause other catkinmake problem, so i tried this
sudo apt-get update
sudo apt-get install ros-indigo-ros-control ros-indigo-ros-controllers
but another error occurs
[ERROR] [1414652580.407543556, 4.281000000]: Exception thrown while initializing controller joint1positioncontroller. Could not find resource 'joint1' in 'hardwareinterface::EffortJointInterface'.

I checked rrbot_control.yamland rrbot.xacro, but of course there was a state about joint1 and joint2.
Was anything wrong? what should i do next?
thanks RYO

I think i solved the problem.
the problem was rrbot.xacro
in the
replace
<joint name="joint1"/>
with
<joint name="joint1">
<hardwareInterface>EffortJointInterface</hardwareInterface>
</joint>
and all error was cleared
thanks for your help.
