Error occured when I roslaunch ur10 moveit

ERROR: cannot launch node of type [moveit_ros_move_group/move_group]: moveit_ros_move_group
ROS path [0]=/opt/ros/indigo/share/ros
ROS path [1]=/home/ccsu/ariac_ws/src
ROS path [2]=/opt/ros/indigo/share
ROS path [3]=/opt/ros/indigo/stacks

Before I launched file, I always setup.bash

Hi @Zhang_Tingshen, it seems like you do not have the right moveit dependencies installed. The moveit dependencies do not get installed by default with ariac. Step 2 of this tutorial should help you install the necessary dependencies (and build the ur10 moveit packages that are specific to ARIAC, if you haven’t already done so). Please be sure to select the indigo tab at the top of the page.
