[ROS] Simulation

NOTE:

  • This instruction has been tested on Ubuntu 16.04 and ROS Kinetic Kame.
  • This instruction is supposed to be run on PC with ROS packages installed in.

Launch gazebo

Load OpenManipulator-X on Gazebo simulator and click on Play ▶ button.

  $ roslaunch open_manipulator_gazebo open_manipulator_gazebo.launch

A red box is pointing end-effector link.

Enter rostopic list to list up the activated topics.

Controller for gazebo

Launch the open_manipulator_controller for gazebo simulation.

  $ roslaunch open_manipulator_controller open_manipulator_controller.launch use_platform:=false

NOTE:

  • To control the OpenMANIPULATOR-X in the Gazebo environment using the OpenMANIPULATOR-X Controller, the controller must set the use_platform parameter to false because it needs to send messages to gazebo instead of Platform.
  • If you want to manipulate the OpenMANIPULATOR-X using Moveit within the Gazebo simulator, you should also convert the use_moveit to true in open_manipulator_controller launch file.

If the OpenMANIPULATOR-X controller for gazebo simulation Launched successfully, the terminal will represent below messages.
