Extra parenthesis in box_arm urdf

Unmatched closing parenthesis in box_arm.urdf.xacro, in line 88, throws following error:

unexpected EOF while parsing (<string>, line 1) 
when evaluating expression '-(AX12_DEPTH + F3_HEIGHT)/2)'

It needs to be removed.
Issue affects indigo and kinetic branch.

can't use rbx2-prereq.sh

When I use $ sh rbx2-prereq.sh to install prereq , terminal return a wrong problem:
can't find ros-indigo-moveit-full.
I fix that one to ros-indigo-moveit , and be all right
Please fix that package name

Does it work with ros kinetic ?

I cloned the kinetic branch and did catkin_make properly, but I get the following error when I run roslaunch rbx2_vision usb_cam.launch

error in Real Pick-and-Place

hi . i want run Real Pick-and-Place using the UBR-1 Perception Pipeline .
when i run roslaunch rbx2_gazebo ubr1_perception.launch
i have error : " ubr1_perception.launch not found"
i dont have ubr1_perception.launch file .
you said : The ubr1_perception.launch file is nearly the same as the grasping.launch file
in the ubr1_grasping package but includes a remapping of the /head_camera topic
used by the UBR-1 to the /camera topic used by the openni_node.launch file.

but i need ubr1_perception.launch file . can you add ubr1_perception.launch file to rbx2_gazebo folder ??
