KUKA KR6R900SIXX Gazebo

Overview

This package contains the configuration files and ros packages required to simulate the kuka kr6r900sixx manipulator in gazebo together with the ros_control packages and the MoveIt! motion planner.

Directory structure of the kuka_experimantal/kuka_kr6_gazebo package:

  • launch directory:  

    • Requires a valid xarco URDF model in the kuka_experimantal/kuka_kr6_support package to load the robot model onto the parameter server. The robot model parameter is saved as robot_description.
    • Inits and starts the gazebo ros_control interface

  • config directory:

    • joint_state_controller.yaml joint state controller to publishes the joint values of the robot
    • arm_controller.yaml JointTrajectoryController which takes in a trajector e.g. from moveit and drives the joints of the robot

  • urdf directory:

    • xml elements, which are required by gazebo to make the urdf file(s) provided in the kuka_experimental/kuka_kr6_support package usable with gazebo, are inserted into the kuka_kr6r900sixx_macro.xarco file!
    • The currently used intertia xml elements are not well/randomly defined, values were added only to provide a functional test simulation! Basic transmission elements have been added to the URDF files. Further improvement may be required to acquire a more realistic simulation.

Build the setup

  1. Install up-to-date ros distribution and source the setup.sh script
  2. cd in the cloned directory from this repo and run catkin_make to build the containing packages.
  3. make sure you have the ros_gazeo_pkgs package installed
  4. if not already in your ~/.basrc file: source $CATKIN_WS/devel/setup.sh

Using Moveit! together with Gazebo Simulator

  1. Bring the robot model into gazebo and load the ros_control controllers: roslaunch kuka_kr6_gazebo kr6r900sixx_gazebo.launch

  2. Launch moveit! and ensure that it is configured to run alongside Gazebo: roslaunch kuka_kr6r900sixx_moveit_config moveit_planning_execution_rsi.launch sim:=true
