Setting up Jackal with Windows¶
We have not yet thoroughly tested ROS Noetic on a Windows-powered Jackal. We have tested with ROS Melodic, and the following documentation is based on those results. Some dependencies may be different for Noetic. We apologize for any inconvenience.
The Clearpath Jackal does not ship with Windows installed by default. However, the core Jackal ROS nodes are enabled on Windows 10, and ROS on Windows is supported by Microsoft. This guide will cover installing Windows on your Jackal, installing ROS & Jackal ROS components, updating firmware and configuring Windows for use.
The following instructions assume that the Jackal is connected to a keyboard and mouse during setup. Once configured, these can be removed and remote access can be leveraged.
For more information on ROS on Windows, please visit Microsoft’s ROS documentation.
Installing Windows 10¶
ROS1 is supported by Microsoft for Windows 10 Desktop and Windows 10 IoT Enterprise. Windows 10 IoT Enterprise is an embedded version of Windows 10 for dedicated purpose devices, such as a Robot.
You can download a trial of Windows 10 IoT Enterprise Long Term Service (LTSC) x64 build, use a Windows license from your Enterprise agreement, or a commercially purchased version of Windows 10 Desktop.
Create a USB Boot stick and copy the contents of the iso generated from the image above.
Boot Windows and install following the prompts.
Install ROS on Windows using the ROS Wiki instructions.
Please follow the instructions closely, as ROS is sensitive to the operating environment.
This will install the development platform on the Jackal, which allows you to develop your robotics solutions. Once you’ve finalized your development, you can build a deployment package and deploy your solutions using Chocolatey.
If you see any problems with Jackal, please get in touch and we’ll see if we can get you sorted out.
Installing Jackal software¶
Once you’ve installed Windows and ROS, It’s time to install the Jackal software. Please open an Administrative ROS command prompt created during the ROS install.
:: Only need to install wget once. choco install wget :: Close and Reopen the command Window. mkdir c:\ws cd c:\ws wget https://raw.githubusercontent.com/jackal/jackal-sphinx-tutorials/master/jackal.rosinstall wstool init src jackal.rosinstall :: Later versions of pyproj are not deployed as a binary and do not build automatically pip install pyproj==1.9.6 rosdep update rosdep install --from-paths src --ignore-src -r -y catkin_make_isolated devel_isolated\setup.bat
rosdep will not find several components. These include rosserial_server, robot_upstart, joint_state_publisher_gui and others. gmapping is coming soon.
The Jackal ROS Nodes and support software is distributed as source code on Github. Other Clearpath repositories have not been enabled as of April 2020, but will be evaluated based on demand.
MCU Firmware Update¶
When you update packages, there is periodically a new version of Jackal’s firmware available.
If new firmware is available, follow the below procedure to flash it to Jackal’s MCU:
Place Jackal up on blocks. Firmware loading does not usually result in unintended motion, but it’s safest when off the ground.
Ensure that Jackal is on and open.
In the top-middle of the main circuit board, look for a small left-right switch in between two buttons.
By default it is in the left position, but move it now to the right position.
Press the reset button to the left, labeled
M_RST. Jackal is now in its bootloader, ready to receive new firmware.
Now, from Jackal’s PC (connected via Windows Remote Desktop or screen/keyboard), in the ROS command Window created during setup:
cd c:\ws devel_isolated\setup.bat rosrun jackal_firmware_ms scripts/upload.bat
During execution of the script, it will display a dialog. Please follow the instructions in the command window.
You should see about 20 seconds worth of lines output beginning with “Download from image …”. When this is complete, move the switch back to the leftmost position and quickly push the reset button again. You’re now running the updated firmware!
If you’re too slow on pushing the reset button, Jackal will power off, including the internal PC. It’s okay if that happens; just press the external power button again, and you should be back in business.
Wireless Network Setup¶
Windows provides an enterprise class network stack. To connect to a Wifi, use the Windows networking user interface to connect to an access point.
Cellular Network Setup¶
For enterprise cellular deployments, please refer to this documentation:
Bluetooth Controller Pairing¶
Windows provides a robust Bluetooth stack. To pair a controller, use the Windows Bluetooth paring user interface.
Once the pairing is complete you should be able to control the robot using your controller. Note that the first time you pair the controller it may be enumerated as the wrong device. If the robot does not respond to your commands, power-cycle the full system and you should be set.
To use teleop on Jackal, clone Microsoft’s fork of the joystick driver, which leverages the Open Source SDL2 library for controller interfaces. You’ll need to ensure that this joystick ROS node is started by your launch files.
cd c:\ws devel_isolated\setup.bat git clone -b init_windows https://github.com/ms-iot/joystick_drivers catkin_make
