UR5e robot description for mc_rtc

UR5e robot description for mc_rtc

This package has additional convex files for mc_ur5e robot module used by mc_rtc control framework. UR5e robot has urdf, collada and meshes in the original ur_e_description package.

It contains the following directories:

• convex/: convex hulls (generated from pointclouds sampled from the dae meshes)
• rsdf/: Special urdf-like format describing surfaces attached to links on the robot (The folder is empty)

Installation

On an environment with ROS and catkin properly setup:

$ cd ~/catkin_ws/src
$ svn export https://github.com/ros-industrial/universal_robot/branches/kinetic-devel/ur_e_description
    (or '$ git clone https://github.com/ros-industrial/universal_robot.git')
$ git clone https://github.com/isri-aist/mc_ur5e_description
$ cd ..
$ catkin_make

Execute convert_from_xacro_to_urdf.sh to generate ur5e.urdf file.

$ @MC_UR5E_DISCRIPTION_PATH@/scripts/convert_from_xacro_to_urdf.sh

Then run the following commands.

$ cd build
$ make install

If your catkin environment is sourced source ~/catkin_ws/install/setup.bash, the robot model will be available to all ROS tools, and mc_rtc robot module.

To display the robot, you can use:

$ roslaunch mc_ur5e_description display_ur5e.launch

• If you have mc_rtc and the corresponding robot module installed, you can use the convexes:=True or surfaces:=True arguments to display the robot convexes and surfaces.

Dependencies

• ur_e_description
• mesh_sampling
• qhull-bin

Generation of convex files

To run the conversion, simply run

$ source ~/catkin_ws/devel/setup.bash
$ cd ~/catkin_ws/src/@MC_UR5E_DESCRIPTION_PATH@/scripts
$ ./generate_convex.sh
