Building from source code

Users may want to make changes to the behavior and feature-set of MotoROS2. To do this, it is necessary to build the MotoROS2 project from source code.

Please note that building from source code is not required for normal usage of MotoROS2. It is only required when you want to change the included functionality.

Requirements

• Microsoft Windows
• Microsoft Visual Studio 2017 or higher (the Community Edition is also known to work). The MotoPlus SDK is not compatible with Visual Studio Code.
• MotoPlus SDK for Visual Studio v1.5.1 or higher. This is not the same as MotoPlus IDE. Users in Asian regions will need to purchase this software from Yaskawa America directly. If you already have a license for an older version of the MotoPlus SDK, please contact [email protected] or [email protected] for assistance obtaining a newer edition.
• libmicroros library and headers that corresponds to your target edition of ROS 2 (Foxy, Humble, etc) and the Yaskawa controller series you are building MotoROS2 for Although libmicroros as used by MotoROS2 is derived from the open-source micro-ROS project, various patches were needed to make it compatible with MotoPlus. As of writing, these patches can not be made open-source yet. Because of this, we distribute the libmicroros dependency as a closed-source library. These can be found on the Releases page

Setup

Clone the yaskawa-global/motoros2 repository.

Obtain the libmicroros and headers for your target ROS 2 variant and controller series.

These are provided as downloads together with the MotoROS2 releases which can be found on the Releases page.

When downloading libmicroros from the repo, the folder will be named with a unique identifier corresponding to the time stamp of the build. Rename the folder to libmicroros_<controller-series>_<ros-2-variant>. E.g. libmicroros_yrc1000_humble.

Move the folder containing libmicroros and the headers inside the folder with the Visual Studio solution (ie: MotoROS2.sln).

Example showing where libmicroros_yrc1000_humble should be moved for a Humble build of MotoROS2 targetting a YRC1000 controller:

motoros2
|-- libmicroros_yrc1000_humble
|   |-- include
|   |   `-- ...
|   |-- build_info.yaml
|   `-- libmicroros.yrcLib_humble
|-- src
|   |-- ...
|   `-- MotoROS2_AllControllers.vcxproj
|-- ...
`-- MotoROS2.sln

Now open MotoROS2.sln in Visual Studio.

Verify project configuration

The Configuration Manager dropdown should be pre-populated with the supported combinations of controller models and ROS 2 variants. If it is not, you will need to add them manually. This procedure will also allow you to verify the Visual Studio project configuration is correct.

1. In the project tree, expand the MotoPlus Libraries > micro-ROS folder. Check for the libmicroros library that was obtained in the Setup procedure above.

   If is is not in the project tree, right-click the MotoPlus Libraries folder in the project tree and select Add > Existing Item.

   

   Navigate to the libmicroros library file and add it to the project.

2. In the top menu, choose Project > Properties. Use the Configuration dropdown to choose the correct configuration for your robot controller model and ROS 2 variant.

   

   Choose VC++ Directories from the left tree view. Verify the path to libmicroros headers exists in the Include Directories field. This can be a relative path, using MSBuild macros. Copy this path, as it will be used again in the next step.

   Example: $(ProjectDir)..\libmicroros_yrc1000_humble\include; NOTE: Do not use the $(SolutionDir) macro in this step. The path should be either relative to the project file or absolute.

   

3. Choose NMake from the left tree view. Ensure the start of the Include Search Path includes the path to the libmicroros headers. Example: $(ProjectDir)..\libmicroros_yrc1000_humble\include;

   

   Click OK to close the properties dialog.

   Repeat these setup instructions for each controller model and ROS 2 variant that you wwant to build MotoROS2 for.

Building

Use the Configuration Manager dropdown to select your target controller model and ROS 2 variant.

From the main menu, navigate to Build > Build MotoROS2 to build the project.

Alternatively, if you are targeting multiple configurations, navigate to Build > Batch Build. Check each configuration that you are targeting and then click Build.
