escpecially if you have forked or cloned the robertalab repository in the past!

The source of the openroberta lab are stored in the Github repository https://github.com/OpenRoberta/openroberta-lab.

The steps below explain how to get started with the sources. If you just want to run the server locally, please have a look into the wiki - installation. If you want to contribute, please get in touch with us, see wiki - Community before you start.

After a fresh git clone you get the openroberta-lab project folder. It includes almost everything you need to setup and extend your own openrobertalab server. License information is available in the docs folder.

Things you need on your computer:

• Java 1.8
• Maven >= 3.2
• Git
• Web browser

If you would like your local server to compile code for the different systems, you need to install additional software (crosscompiler, ...):

on linux:

• Arduino based robots
  • sudo apt-get install libusb-0.1-4
  • sudo apt-get install gcc-avr binutils-avr gdb-avr avr-libc avrdude
• NXT
  • sudo apt-get install nbc
• Calliope
  • sudo apt-get install gcc-arm-none-eabi srecord libssl-dev
• micro:bit
  • pip install uflash

on windows:

• Calliope
  • install gcc-arm-none-eabi (see: http://gnuarmeclipse.github.io/toolchain/install/)
  • install srecord (see: http://srecord.sourceforge.net/)
• micro:bit
  • install python
  • pip install uflash

The crossompiler need resources to work properly (header files, libraries, ...). These resources change little over time and are stored in a repository of its own:

https://github.com/OpenRoberta/ora-cc-rsc.git

Please clone that directory. When the openrobertalab server is started, you have to supply the path to these resources (see below). If the resources are not available, everything works fine (writing programs, import, export, creating accounts, etc.), but running programs on real robots doesn't work, because the crosscompiler will fail.

Please also check our wiki for detailed installation instructions, development procedure, coding conventions and further reading. We also use the github issue tracking system. Please file issues in the main project openroberta-lab.

git clone https://github.com/OpenRoberta/openroberta-lab.git # get the repository
cd openroberta-lab                                           # cd into repository
mvn clean install                                            # generate the server

Might take some time. The last lines of a successful build looks like:

If you have a fresh clone of the server, make sure that the OpenRobertaServer folder has a subfolder db-x.y.z with the database inside, where x.y.z is the current version from the server. The actual server version is found in the pom.xml of the OpenRobertaParent project. If you don't have a database, you can create an empty database with

./ora.sh create-empty-db

./ora.sh start-from-git [optional-path-to-crosscompiler-resources] # start the server using the default properties

You can also run ./ora.sh help to see more commands for administration of the server. If you have Eclipse installed and

• the repositories base directory is imported as maven project (this will import all submodules automatically)

• a maven build in the repositories base directory has been executed and a database is created (see above!)

• a run configuration is created with

  • OpenRobertaServer as project

  • de.fhg.iais.roberta.main.ServerStarter as main class

  • and the program arguments are set to

    -d server.staticresources.dir=./staticResources
    -d robot.crosscompiler.resourcebase=[optional-path-to-crosscompiler-resources]
    -d database.parentdir=. -d server.tutorial.dir=../Resources/tutorial
    

• then the server can be started with this run configuration

Start your browser at: http://localhost:1999

That's it!

You can follow the test status on https://travis-ci.org/OpenRoberta/.

Development happens in the develop branch. Please sent PRs against that branch.

git clone https://github.com/OpenRoberta/openroberta-lab.git
cd openroberta-lab
git checkout develop

The project OpenRobertaServer contains the server logic, that accesses

• a database with Hibernate-based DAO objects
• plugins for various robots which are supported in OpenRoberta
• services for browser-based clients
• services for robots connected to the lab either by Wifi or USB

The server is made of

• an embedded jetty server exposing REST services
• the services are based on jersey
• JSON (sometimes XML or plain text) is used for data exchange between front, robots and server

Furthermore, the project OpenRobertaServer contains in directory staticResources for the browser client

• HTML and CSS
• Javascript libraries based on jquery and bootstrap for the frontend
  • assertions (DBC), ajax-based server calls (COMM), logging (LOG) and
  • javascript resources for blockly (see: http://code.google.com/p/blockly/)
  • controller and models written in Javascript, which implement the GUI

To run tests, use mvn test. Running mvn clean install will make a stable, reproducible build with all unit tests executed.

We are using Blockly, it is located in a separate repository. The build of the blockly is only done in the OpenRoberta/Blockly project and then copied to the OpenRobertaServer/staticResources. You can not build Blockly in OpenRobertaServer project directly.

Build status:

• master
• develop
