Pre-requisite Software Setup

The ROS driver for the robots is initially supported for the ROS Noetic. All of ROS related software should be installed in a remote Husky-PC as well as the Remote-PC. The steps for shown below are for Remote-PC as the Husky is pre-installed with the required drivers and ROS distribution.

PC Setup

ROS Noetic installation requires Ubutnu 20.04.

1. Download Ubuntu 20.04

2. Follow the Ubuntu 20.04 Installation guide

ROS-noetic Installation

The ros driver provided can be run either on a remote PC or on board robot computer. Usually, the on-board computer already has pre-installed ROS distribution, so the instructions below will be applicable to a remote computer. You may run the following commands to install ROS noetic or you can simply follow the instructions from the roswiki.

1. Enter the Ubuntu terminal and typie in the following command:

cd

2. The next step is setting up the source list:

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'

3. After which you will set up the keys:

sudo apt install curl
curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -

4. Then, you will install ROS-noetic:

sudo apt update
sudo apt install ros-noetic-desktop-full

5. Finally, you will add ROS environment to your bash file, what this means is that each time you load up your terminal, it will automatically find the built-in ROS packages.

echo "source /opt/ros/noetic/setup.bash" >> ~/.bashrc
source ~/.bashrc

6. Install python dependencies and initialize repo:

sudo apt install python3-rosdep python3-rosinstall python3-rosinstall-generator python3-wstool build-essential
sudo rosdep init
rosdep update

Once the ROS packages are set-up the next step would be to set up a workspace in which you can add pre-built packages to control your robot.

Catkin Workspace

1. The first step is to ensure that you have correctly setup you ROS noetic. It can be checked by:

cd ..
source /opt/ros/noetic/setup.bash

2. Next, install catkin_tools:

sudo apt install python3-catkin-tools

3. The next step is to create, your workspace. This is typically created in the home directory following the standard ROS convention, once built, you should see a build and devel folder next to your src folder:

mkdir -p ~/catkin_ws/src
cd ~/catkin_ws/
catkin build

4. To enable the workspace, you must type in:

source devel/setup.bash

5. To avoid typing this everytime you start a terminal, you’ll add this into the last line of the bashrc file:

gedit ~/.bashrc

• Add the following line at the end of the bashrc file:

source /home/<your_computer_username>/catkin_ws/devel/setup.bash

• Everytime you do a catkin build, it is necessary to either restart all your terminals, or source them.

• To verify that everything is working correctly, type the following into the terminal:

echo $ROS_PACKAGE_PATH

MBS Compliant Manipulation Installation

The package is designed to support industrial robot operation for non-technical users. Currently the supported manipulator is Ufactory xArm6.

Attention

To get the source packages for the user interface and xArm6 controllers. Send an email to support@mybotshop.de

• Give root permission to the installation script via

sudo chmod +x Installation_script.bash

• Run the script from the terminal via

./Installation_script.bash

• Provide the workspace name as catkin_ws

• Provide the directory as /home/administrator.

Note

In case the username is not administrator then manual changes will have to be made in the startup job.
