- Latest Build Nixie 1.1.(Latest)
- Latest Javadocs Javdocs
You will need Java 11 or newer. If you are only running MyRobotLab you need the JRE (Java Runtime Environment.) If you are going to be building from source, you'll need the JDK (Java Development Kit) Oracle or OpenJDK will work
Download
latest Nixie 1.1.X
After downloading and unzipping myrobtlab.zip into a new folder, start the appropriate script
myrobotlab.shmyrobotlab.bat
The first time the script runs it will automatically install all services and their dependencies, then it will launch myrobotlab. This can take a long time depending on the speed of your internet connection. The subsequent starting of myrobotlab will skip the installation stage. If a browser does not automatically start you can go to http://localhost:8888 to see the web user interface.
MyRobotLab core is written in Java, it is a maven project - Any IDE which can load maven should work. Its web ui is written in AngularJs and html.
A few services (e.g. InMoov2 & ProgramAB) are in a different repo. The can be developed seperately so 3 build instruction sets are described.
All development environments require git and cloning the source.
create a directory to clone the repositories in (assuming you're on windows and cloning to the c:\dev directory)
mkdir c:\dev
cd dev
git clone https://github.com/MyRobotLab/myrobotlab.git
cd c:\dev\myrobotlab
If you want to be making core changes, you will need to install a Java developement environment
https://www.oracle.com/java/technologies/downloads/#java11
Download Eclipse for Java Developers At: https://www.eclipse.org/downloads/packages/
MyRobotLab builds using the Apache Maven java build system.
Download Maven At: https://maven.apache.org/download.cgi
To compile and build a myrobotlab.jar first : ensure that "mvn" (maven version 3.3+ is installed and in the path)
mvn clean install
This should produce a local build for you "myrobotlab.jar" file will be located at
myrobotlab/target/myrobotlab.jar
If you want to compile and skip the tests, you can use the standard maven approach
mvn clean install -DskipTests
All development is done on the develop branch. To contribute code, the typical approach is to create an issue about the feature/bug you're working on.
From Github create a branch based off the "develop" branch with a descriptive name (and associated Issue number if available) Locally switch to the new branch Make code changes Commit & Push (frequently!) When code is ready, submit a pull request to the develop branch! Enjoy the code review, address issues and concern in the code review Reviewer merges pull request to develop. Reviewer deletes branch.
The following config should be useful to work directly on WebGui UI and InMoov2 UI if the repos are submoduled under src/main/resources/resource/InMoov2, src/main/resources/resource/ProgramAB

The Path API definition is a simple way to define a RESTful API. The path is parsed and the service name, method name, and parameters are extracted. The parameters are json encoded and converted to the correct type when the method is invoked. The response is returned as a JSON object. The REST and CLI both use this API definition.
http://localhost:8888/runtime/getUptime
http://localhost:8888/runtime/connect/"http://main.myrobotlab.org:8888"
http://localhost:8888/arduino/connect/"COM3"
The exact same paths can be used in the CLI
/runtime/getUptime
/runtime/connect/"http://main.myrobotlab.org:8888"
/arduino/connect/"COM3"
A connection with a websocket starts with an HTTP GET
ws://localhost:8888/api/messages?user=root&pwd=pwd&session_id=2309adf3dlkdk&id=p1
When a connection is established between two different myrobotlab instances p1 and p2, the following messages are sent. The first message is adding a subscription to the runtime of the other process. The subscription is for the function "describe". The second message will be a describe request.

}The response back will include serialized services which should be refactor to be more minimal, and more describe parameters which can return interfaces or methods Services returned from the Describe request have been registered. By default they are only the currently "local" registered services.
The response should be refactored so that the material returned is related to criterial requested. For example, if only a list of services and their names are needed, that is all that is returned. If a specific service's interfaces are requested, then that is only returned. Fill-UUID should be refactored out.
