Getting Started with a Aubo Robot

Description: This tutorial guides you through the process of establishing contact between ROS and a Aubo Robot

Tutorial Level: INTERMEDIATE

Prerequisites

In order to complete this tutorial, you should have access to the following:

  1. A computer with ROS installed (Indigo or Jade)
  2. Peak Can linux driver.
  3. Package aubo_robot

This particular tutorial was tested on a Aubo robotic manipulator. The operating system based on Ubuntu 14.04(Supports both 32bit and 64bit version).

Overview

The aubo_robot metapackage communicates with hardware via Peak can tools, and also Ethernet connection.

Install necessary software

Peak can driver

  1. Install libpopt lib.
    •    $sudo apt-get install libpopt-dev
  2. Install peak can driver,download: http://www.peak-system.com/fileadmin/media/linux/

    •    $tar -zxvf peak-linux-driver-8.1.tar.gz
         $cd peak-linux-driver-8.1
         $make clean
         $make net=NO_NETDEV_SUPPORT
         $sudo make install

Catkin workspace

There are releases available for ROS Indigo. However, for the latest features and developments you might want to install from source.

  1. First set up a catkin workspace (see http://wiki.ros.org/catkin/Tutorials).

  2. Then clone the [https://github.com/aubo_robot] repository into the src/folder. Make sure to select the applicable branch before cloning (e.g. Indigo). It should look like /home/your/catkin_ws/src/aubo_robot.

  3. Make sure to source the correct setup file according to your workspace hierarchy, then use catkin_make to compile.

  4. If there is a linking dependency in aubo_driver with libev library. It is necessary to install it use sudo apt-get install libev-dev.

Move robot

Control real robot use pcan directly

  1. Make sure have installed Peakcan driver, connect peackcan to aubo robot i5, then run command,optional parameter(-S1,-S2,-S3) can control the joint move speed.
    •    $rosrun aubo_control joint_control_pcan -S1

      Note:default joint move speed is S1.

  2. A simple control panel in Rviz,run command line like this:
    •    $roslaunch aubo_description aubo_i5_rviz.launch

      Note:Choose PCAN bus interface, and select "Continuous move" mode.

    • Then we can control 6 joints with press button "+" and "-".

Control real robot use TCP/IP Server

  1. Firstly,check the Robot Controller's IP address,for example 192.168.1.34,then ping 192.168.1.34,make sure is connected. run command line like this:
    •    $roslaunch aubo_driver aubo_i5_bringup.launch robot_ip:=192.168.1.34
    • Choose TCP/IP bus interface, and select "Move to Goal with AUBO Plan API "mode. Then we can adjust 6 joints position with press button "+" and "-",and also you can choose classic position. Then, push button "sendGoal".

Using MoveIt! with real robot in Rviz

There is a trajectory demo for this part use Peakcan Tool,also can use TCP/IP bus interface.

  1. Make sure have installed Peakcan driver, connect peackcan to aubo robot i5, then run command,optional parameter(-S1,-S2,-S3) can control the joint move speed.
    •    $rosrun aubo_control joint_control_pcan -S1

      Note:default joint move speed is S1.

  2. For starting up Rviz with a configuration including the MoveIt! Motion Planning plugin run:

    •    $roslaunch aubo_i5_moveit_config demo.launch
  3. Start up a trajectory generator,which receive goal and make trajectory,run:
    •    $rosrun aubo_trajectory trajectory_gen
  4. Start up trajectory goal,subscribe trajectory points and publish to joint_control_pcan:
    •    $rosrun aubo_trajectory trajectory_goal
  5. A control panel with real robot,run command:
    •    $roslaunch aubo_description aubo_i5_rviz.launch

Using MoveIt! with simulated robot in Gazebo

  1. To bring up the simulated robot in Gazebo, run:
    •    $roslaunch aubo_gazebo aubo_i5.launch
  2. For setting up the MoveIt! nodes to allow motion planning ,run:

    • make sure the follow context at aubo_i5_moveit_planning_execution.launch file:

      "<remap if="$(arg sim)" from="/follow_joint_trajectory" to="/arm_controller/follow_joint_trajectory"/>"

         $roslaunch aubo_i5_moveit_config aubo_i5_moveit_planning_execution.launch sim:=ture
  3. For starting up RViz with a configuration including the MoveIt! Motion Planning plugin run:

    •    $roslaunch aubo_i5_moveit_config moveit_rviz.launch config:=true

RealTime Interface with a real robot

  1. This new function use FollowJointTrajectoryAction server to control the AUBO-I5.

    •     $roslaunch aubo_new_driver aubo_i5_bringup.launch robot_ip:=xxx.xxx.xxx.xxx
      • or use ros control,
          $roslaunch aubo_new_driver aubo_i5_ros_control.launch robot_ip:=xxx.xxx.xxx.xxx
  2. there are two example in "aubo_new_driver/test".

MoveIt!use ros control with a real robot

  1. Start up aubo new driver
    •   $roslaunch aubo_new_driver aubo_i5_ros_control.launch robot_ip:=xxx.xxx.xxx.xxx
  2. For setting up the MoveIt! nodes to allow motion planning run:

    • make sure the follow context at aubo_i5_moveit_planning_execution.launch file:

      "<remap if="$(arg sim)" from="/follow_joint_trajectory" to="/pos_based_pos_traj_controller/follow_joint_trajectory"/>"

        $roslaunch aubo_i5_moveit_config aubo_i5_moveit_planning_execution.launch sim:=true
  3. For starting up Rviz with a configuration including the MoveIt! Motion Planning plugin run:

    •   $roslaunch aubo_i5_moveit_config moveit_rviz.launch config:=true
  4. Drag the end effector of simulated Robot,then plan and excute.
