Tested Platforms

Robots

Developers

We test all of our software on OSX, Windows, and Ubuntu. It is likely to work on other platforms but not necessarily tested.

Branches

This repository uses the git-flow branching model. You can find more about git-flow here.

Licensing

All of the software in IHMC Open Robotics Software is licensed under the Apache 2.0 license.

Getting Started

Using IHMC Open Robotics Software .jar releases with Maven/Gradle

The release .jars for the various IHMC Open Robotics Software packages are hosted on Bintray. You can browse the release packages at https://bintray.com/ihmcrobotics/maven-release. Instructions for adding the Maven repository and identifying the artifacts can also be found on Bintray for each package.

At a minimum, you will need to have the following repositories declared in your build script to use IHMC Open Robotics Software .jars:

repositories {
   maven {
      url  "http://dl.bintray.com/ihmcrobotics/maven-release" // IHMC Code releases
   }
   maven {
      url  "http://dl.bintray.com/ihmcrobotics/maven-vendor" // Third-party libraries that we have vendored for various reasons
   }

   /* You will also need to add either jcenter() or mavenCentral() or both, depending on your preference */
}

Developing with IHMC Open Robotics Software from source

Requirements

IHMC Open Robotics Software uses the Gradle build system, and requires JDK 8 with JavaFX. We also strongly suggest an IDE, either Eclipse or IntelliJ (Ultimate or Community is fine). Currently, we require Gradle 4.10+.

Installing Gradle: https://gradle.org/install/

Companion Software

Other IHMC Libraries

IHMC Open Robotics Software both depends on and is depended on by many other IHMC Robotics Libraries. A small sampling of our other software includes:

You can find all of our other repositories as well as the ones above at https://github.com/ihmcrobotics

ROS API's

We provide a native ROS 2 API for many of the core components in our software stack. You can find the .msg definitions for use in your own projects here: https://github.com/ihmcrobotics/ihmc_interfaces

We have ROS 1 support via the ROS 2 ros1_bridge package. You can find the ROS 1 message definitions and instructions on using the ROS 1 Bridge here: https://github.com/ihmcrobotics/ihmc_msgs

IDE Support

Our Gradle models are tested in IntelliJ IDEA 2018 (both Community and Ultimate) with the Gradle plugin. Eclipse 2018.09+ or higher with the Buildship plugin. The Buildship plugin is bundled with the Eclipse IDE for Java Developers (but not Java EE Developers). It can always be manually installed to any version of Eclipse using the installation instructions.

Building .jars

IHMC Open Robotics Software is pre-configured for generating Maven publications. You can publish directly from the source code right in to your local Maven repository, e.g. the $HOME/.m2 directory. These builds will be tagged with a build "version" of "LOCAL" instead of an incrementing version number.

An example workflow for developing against a local clone of the software:

  1. Clone IHMC Open Robotics Software
  2. Make modifications
  3. Publish to your local $HOME/.m2 repository

To publish jars to your local Maven repository:

$ cd /path/to/ihmc-open-robotics-software
$ gradle publishAll -PcompositeSearchHeight=0

To depend on the jars in your local Maven repository:

In this example we'll have a compile-time dependency of the locally built Simulation Construction Set project. In the build.gradle of the project you wish to have link against Simulation Construction Set:

repositories {
  mavenLocal()
  <your other repositories>
}

dependencies {
  compile group: "us.ihmc", name: "simulation-construction-set", version: "LOCAL", changing: true
}

Creating a project

To create a project that uses IHMC Open Robotics Software, your project hierarchy needs to take a particular form.

First be sure you have completed the section above titled "Clone repositories".

Next, create your project folder:

mkdir -p src/ihmc/my-project-a

Follow the project setup tutorial at https://github.com/ihmcrobotics/ihmc-build#quick-project-setup.

Your directory structure should now look something like:

src/ihmc
├── my-project-a
│   └── build.gradle
│   └── gradle.properties
│   └── settings.gradle
├── my-project-b
│   └── ...
├── ihmc-open-robotics-software
│   └── atlas
│   └── common-walking-control-modules
│   └── ...
├── my-multi-project-c
│   └── subproject-a
│   │  └── build.gradle
│   └── subproject-b
│      └── build.gradle
├── ...
├── build.gradle
├── gradle.properties
└── settings.gradle

If this is set up correctly, you will have applied the ihmc-build plugin and use the dependency resolver methods exposed by the build extension. Alternatively, you can manually identify dependencies on projects using the normal Gradle syntax for project dependencies. A sample build.gradle dependency block:

/* Normal Gradle way */
dependencies {
  compile project(':ihmc-open-robotics-software:ihmc-java-toolkit')
  testCompile project(':ihmc-open-robotics-software:ihmc-java-toolkit-test')
}

/* ihmc-build way */
mainDependencies {
  compile group: "us.ihmc", name: "ihmc-java-toolkit", version: "source"
}
testDependencies {
  compile group: "us.ihmc", name: "ihmc-java-toolkit-test", version: "source"
}
