Previous steps

Installation of moveIt!

MoveIt! is a package that provides a software tool for all types of manipulation tasks both industrial level and domestic level. It is available for the ROS distributions groovy and hydro, for this reason we must have installed some of these. We will execute the next command in a terminal in order to install moveIt!, where "ROS_DISTRIBUCION" is our installed distribution:

sudo apt-get install ros-ROS_DISTRIBUCION-moveit-full

Modification of MYRAbot model for moveIt!

New URDF of the arm

We need to modify the type of the gazebo controllers of the arm's joints in order to allow to moveIt! to take the control of these. Also we have added the 3D meshes of the real components of the arm. We will create a file named "brazo-macros_moveit.xacro" within the folder "urdf" of the package "brazo_fer_modelo" with the content that is shown below:

Integration of arm's controllers

We will create a file named "controllers.yaml" within the folder "config" of the generated moveIt! package with the content that is show below:

controller_list:
 - name: brazo_controller
   action_ns: follow_joint_trajectory
   type: FollowJointTrajectory
   default: true
   joints:
     - arti1
     - arti2
     - arti3
     - base

We have to add the nest code lines in the file "MYRAbot_moveit_controller_manager.launch.xml" placed in the folder "launch" of the generated moveIt! package:

<launch>

 <!-- Set the param that trajectory_execution_manager needs to find the controller plugin -->
 <arg name="moveit_controller_manager" default="moveit_simple_controller_manager/MoveItSimpleControllerManager" />
 <param name="moveit_controller_manager" value="$(arg moveit_controller_manager)"/>
 
 <!-- load controller_list -->
 <rosparam file="$(find myrabot_moveit_generated)/config/controllers.yaml"/>

</launch>

Integration of perception sensors

We can use the asus xtion pro live or the kinect in MYRAbot, we configure both in the same way. We will create a file named "xtion.yaml" within the folder "config" of the generated moveIt! package with the content that is shown below:

We have to add the nest code lines in the file "MYRAbot_moveit_sensor_manager.launch.xml" placed in the folder "launch" of the generated moveIt! package:

<launch>

 <rosparam command="load" file="$(find myrabot_moveit_generated)/config/xtion.yaml" />
 <param name="octomap_frame" type="string" value="odom" />
 <param name="octomap_resolution" type="double" value="0.05" />
 <param name="max_range" type="double" value="5.0" />

</launch>

We have to add the value 'move_group/MoveGroupGetPlanningSceneService in the parameter "papabilities" in the file "move_group.launch" placed in the folder "launch" of the generated moveIt! package, like is shown below:

...

    <!-- MoveGroup capabilities to load -->
    <param name="capabilities" value="move_group/MoveGroupCartesianPathService
				      move_group/MoveGroupExecuteService
				      move_group/MoveGroupKinematicsService
				      move_group/MoveGroupMoveAction
				      move_group/MoveGroupPickPlaceAction
				      move_group/MoveGroupPlanService
				      move_group/MoveGroupQueryPlannersService
				      move_group/MoveGroupStateValidationService
				      move_group/MoveGroupGetPlanningSceneService
				      " />

...

Modification of the .srdf file generated

We have to edit the generated file "MYRAbot.srdf" placed in the folder "config" of the generated moveIt! package in order to replace the commas by dots in the values of the joints in the stored group poses, like is shown below:

    <group_state name="home" group="brazo">
        <joint name="arti1" value="1,3836" />
        <joint name="arti2" value="-2,2458" />
        <joint name="arti3" value="-0,7065" />
        <joint name="base" value="0" />
    </group_state>

by

    <group_state name="home" group="brazo">
        <joint name="arti1" value="1.3836" />
        <joint name="arti2" value="-2.2458" />
        <joint name="arti3" value="-0.7065" />
        <joint name="base" value="0" />
    </group_state>

Execution

Simple planning

We will execute the next command in a terminal in order to test that the MYRAbot works properly in moveIt!:

roslaunch myrabot_moveit_generated demo.launch

When the load process finish we can see the MYRAbot model in rviz with the Motion Planning Interface of moveIt!, like is shown in the next picture:

MYRAbot in rviz with plugin of moveIt!

If the interact mode is selected we can see a interactive markers around the gripper. We will use the interactive markers to interact with the representation of the start state and the goal state. If we open Planning Request within of MotionPlanning we can show or hide the representation of Query Start State (arm's joints green-coloured) and Query Goal State (arm's joints orange-coloured). When a part of the arm collides with other part of the robot or other object, its colour change to red.

We can see in the next video a simple planning, without obstacles, that moves the arm from a start pose (stored pose home) until a goal pose (using the interactive marker):

Planning with modelled scene

We will execute the next command in a terminal in order to start rviz with the robot model and the "MotionPlanning" of moveIt!:

roslaunch myrabot_moveit_generated demo.launch

We have created a scene with basic geometry figures that represent a table and a can. We have not used 3D meshes because they may swap randomly. We will create a file named "mesa_lata.scene" within our personal folder with the content that is shown below:

Mesa_Lata
* mesa_pata_izquierda_delantera
1
cylinder
0.015 0.71
0.20 0.97 0.355

* lata
1
cylinder
0.03 0.12
0.28 0 0.8
0 0 0 1

.

We will load the scene clicking on Import From Text in the menu Scene Objects of MotionPlanning. We can see in the next video the load process and planning to avoid the can that is represents by a red cylinder over the table:

Planning with robot in gazebo

We will create a file named "myrabot_gazebo_moveit_mesa+latas.launch" within the folder "launch" of the package "myrabot_fer_modelo" with the content that is shown below in order to load the objects' models (table and cans):

<launch>
  
  <include file="$(find myrabot_fer_modelo)/launch/myrabot_gazebo_moveit.launch" />

  <!-- Load models table and cans -->
  <node name="spawn_mesa" pkg="gazebo_ros" type="spawn_model" args="-file $(find myrabot_objects_models_b)/urdf/mesa.urdf -urdf -x 0.545 -y 0 -z 0 -Y -1.57 -model mesa" respawn="false" output="screen" />    
  
  <!--node name="spawn_lata_coca_cola" pkg="gazebo_ros" type="spawn_model" args="-file $(find myrabot_objects_models_b)/urdf/lata_coca_cola.urdf -urdf -x 0.32 -y -0.18 -z 0.74 -Y -1.57 -model lata_Coca_Cola" respawn="false" output="screen" /-->  

  <node name="spawn_lata_amstel" pkg="gazebo_ros" type="spawn_model" args="-file $(find myrabot_objects_models_b)/urdf/lata_amstel.urdf -urdf -x 0.32 -y 0.0 -z 0.74 -Y -1.57 -model lata_Amstel" respawn="false" output="screen" /> 

</launch>

We will create a file named "moveit_planning_execution.launch" within the folder "launch" of the created moveIt! package with the content that is shown below:

<launch>
 # The planning and execution components of MoveIt! configured to 
 # publish the current configuration of the robot (simulated or real)
 # and the current state of the world as seen by the planner
 <include file="$(find myrabot_moveit_generated)/launch/move_group.launch">
  <arg name="publish_monitored_planning_scene" value="true" />
 </include>
 # The visualization component of MoveIt!
 <include file="$(find myrabot_moveit_generated)/launch/moveit_rviz.launch"/>
</launch>

We will execute the next command in a terminal in order to start gazebo with the robot model and objects' models:

roslaunch myrabot_fer_modelo myrabot_gazebo_moveit_mesa+latas.launch

We will execute the next command in a new terminal in order to start rviz with the "Motion Planning Interface" of moveIt!:

roslaunch myrabot_moveit_generated moveit_planning_execution.launch

The represented scene in rviz corresponds with the scene captured by the perception sensor, the boxes represent the occupied space. We can see in the next video the planning to avoid the can and the replanning because the first calculated trajectory collides with the can:
