1. Universal Robot 5 Installation

Official installation tutorial

The following command lines are for ur5 installation in ros-kinetic

mkdir -p ur5_ws/src
cd ur5_ws/src

# retrieve the sources
git clone -b kinetic-devel https://github.com/ros-industrial/universal_robot.git

cd ~/ur5_ws

# checking dependencies
rosdep install --from-paths src --ignore-src --rosdistro kinetic

# buildin,
catkin_make

# if there is any error, try
# pip uninstall em
# pip install empy

# source this workspace (careful when also sourcing others)
cd ~/ur5_ws
source devel/setup.bash

To run UR5 in Gazebo and rviz (source devel/setup.bash)

roslaunch ur_gazebo ur5.launch limited:=true

roslaunch ur5_moveit_config ur5_moveit_planning_execution.launch sim:=true limited:=true

roslaunch ur5_moveit_config moveit_rviz.launch config:=true

To test UR5 motion, run testmotion.py Look into this link for straight line motion

2. Moveit

Official tutorial

2.0 Install Moveit
sudo apt-get install ros-kinetic-moveit

launch teh Moveit Setup Assistant

roslaunch moveit_setup_assistant setup_assistant.launch

1. Click on the "Create New MoveIt Configuration Package" button,click the "Browse" button, select the xacro file you created in the Previous Chapter, and click on the "Load Files" button.
PATH: /src/universal_robot/ur_description/urdf/ur5.urdf.xacro

2. Go to the "Self-Collisions" tab, and click on the "Regenerate Collision Matrix" button.

3. move to the "Virtual Joints" tab. Here, you will define a virtual joint for the base of the robot. Click the "Add Virtual Joint" button, and set the name of this joint to FixedBase, and the parent to world.

4. open the "Planning Groups" tab and click the "Add Group" button. Now, you will create a new group called manipulator, which uses the KDLKinematicsPlugin.

3. Move Group Python InterFace Tutorial[`Official tutorial`](http://docs.ros.org/indigo/api/moveit_tutorials/html/doc/pr2_tutorials/planning/scripts/doc/move_group_python_interface_tutorial.html)

2.1 Use Moveit Interface

Move Group Interface Tutorial

2.2 Use Moveit in Python

Cartesian Path Planning

Using the ur5 with the MoveIt Motion Planning Framework for quick motion planning. Install the package from package management, and run the MoveIt! planning demo:

$ sudo apt-get install ros-kinetic-ur5-moveit-config

$ roslaunch ur5_moveit_config demo.launch

Our goal is to move the universal robot (ur5) end effector moving in straight line (Cartesian path) with Moveit-Python interface.

3 USB Camera Installation in ROS

Reference link

To list all video devices picked up by the kernel

$ ls -ltrh /dev/video*
$ cd ur5_ws/src

$ git clone https://github.com/bosch-ros-pkg/usb_cam.git

$ cd ..

$ catkin_make

$ source devel/setup.bash

$ roscd usb_cam

# run `roscore` in a new terminal
# Make sure a usb cam is connected

To connect external cam. Locate the usb_cam-test.launch file in folder

cd ~/ur5_ws/src/usb_cam/launch

Change

<param name="video_device" value="/dev/video0" />

to

<param name="video_device" value="/dev/video1" />

From

cd ~/catkin-ws/src/usb_cam/launch run

roslaunch usb_cam-test.launch

If this works, quit the test program, open rviz

rosrun rviz rviz

run the following command in ur5_ws folder (source devel/setup.bash)

rosrun usb_cam usb_cam_node

4. Revolute-Revolute Manipulator Robot

"RRBot, or ''Revolute-Revolute Manipulator Robot'', is a simple 3-linkage, 2-joint arm that we will use to demonstrate various features of Gazebo and URDFs. It essentially a double inverted pendulum and demonstrates some fun control concepts within a simulator."

To get RRBot, clone the gazebo_ros_demos Github repo into the /src folder of your catkin workspace and rebuild your workspace:

cd ~/catkin_ws/src/
git clone https://github.com/ros-simulation/gazebo_ros_demos.git
cd ..
catkin_make
source devel/setup.bash

Quick start

Rviz:

roslaunch rrbot_description rrbot_rviz.launch

Gazebo:

roslaunch rrbot_gazebo rrbot_world.launch

ROS Control:

roslaunch rrbot_control rrbot_control.launch

Example of Moving Joints:

rostopic pub /rrbot/joint2_position_controller/command std_msgs/Float64 "data: -0.9"

5. Using Gazebo Camera Plugins

roslaunch ur_description ur5_upload.launch
roslaunch ur_description test.launch

You probably need to install urdf_tutorial:

cd ~/catkin_ws/src/
git clone https://github.com/ros/urdf_tutorial
cd ..
catkin_make
source devel/setup.bash

In rviz, the first task is to choose the frame of reference for the visualization. In left panel, Global Options/Fixed Frame, choose a proper frame (e. g. world)

Next, we want to view the 3D model of the robot. To accomplish this, we will insert an instance of the robot model plugin To add the robot model to the rviz scene, click the “Add” button and choose RobotModel

To test UR5 USB cam, run testvision.py

5. gazebo world Launch

launch gazebo files :

roslaunch ur5_notebook initialize.launch

change object pose and twist with command line:

rosservice call /gazebo/set_model_state '{model_state: { model_name: red_box, pose: { position: { x: 0, y: 0 ,z: 1 }, orientation: {x: 0, y: 0, z: 0, w: 0 } }, twist: { linear: {x: 0.1 , y: 0 ,z: 0 } , angular: { x: 0.0 , y: 0 , z: 0.0 } } , reference_frame: world } }'
