Here you will find all information about the Open Roberta Lab and about our "Open Roberta operating system" (also called Open Roberta Firmware). Initially we describe the menu items in the Open Roberta Lab and what is behind the menu items. We tried to keep the Open Roberta Lab as simple as possible.
There are five menu items on the left: Edit - Robots - Help - User - Language.
In this menu item you'll find everything you can do with your program. In addition, you can chose NEPO blocks you want to program, e.g. beginner blocks or experts blocks.
run on robot
By selecting this submenu you run the program on the robot. For this purpose your program and the configuration of your robot will be sent to the Open Roberta Lab servers. There the readable robot machine code is generated and sent to your robot. The robot runs the program as soon as it is completely transferred.
If a robot is connected you will receive a direct message. You can see in the right concer of the menu an existing connection besides the green robot icon.
The "start" of a program can be detected at different points within the Open Roberta Lab and at your robot:
A message appears In the top center of the Open Roberta Lab, indicating for some seconds that your program will be processed.
The NEPO logo appears at the robot display prior to starting the program on the robot.
While your program is running, the robot icon in the right of the Open Roberta Lab menu flashes red and green.
You can start a program by a single click from the programming area.
run in simulation
This command starts your program in the simulation environment. The program will be sent to the simulator and may be executed with the simulation start button. The robot configuration is a standard configuration.
In a future release of the software you may check that your program and the robot configuration match and that the program execution is possible from the Open Roberta Lab. This submenu item has not yet been entirely completed, so possibly it is not yet clickable.
Clear the programming window to create a new program. If the current program has been changed there will be a warning that you should save the changes.
my programs ...
Displays all your saved programs. For this, you need to log in the menu »user« or you have create a new user account with »new«.
Share your program with friends.
multiple robot simulation ...
Start two or more programs in the simulation environment.
At least two stored programs.
example programs ...
Some example programs to choose for initial experiments.
If you are logged in and your program has already been given a name with »save as«, you can save program changes. The same functionality is available by using the button in the lower right corner of the screen.
save as ...
If you are logged in, you can save your program by entering a new name for the program.
You can use this window to describe your program.
A code windows will be rolled out to show the java code that was generated from the blocks program.
Open Source Code Editor
Edit and build the text-based source code in the Open Roberta Lab and then run it on the device.
Build the Source Code
Edit and build the source code. When you are finished, click on the wrench to build the code.
Make sure that you type everything in correctly, otherwise you will get an error message from the lab.
Run on robot
To run your program on a robot, simply press Start.
Programs can also be downloaded and saved on the PC.
Using the export program command is used to store the current program on a local storage device. An explorer window will be opened to browse for an export folder. XML code will be generated end stored. This is always useful if the Open Roberta cloud is not available.
The import program command is useful to restore a program stored on a local storage device. An explorer window will be opened to browse for the program to import.
Warning! Importing a program will overwrite the current program. You should definitely save it first.
Clicking the buttonabove the block toolbox will switch the toolbox to the beginner toolbox, which contains a reduced selection of the blocks that are available in the Open Roberta Lab, which is ideal for beginners.
Clicking the buttonabove the block toolbox will switch the toolbox to the expert toolbox, which contains all available blocks in the Open Roberta Lab.
Your choice of robots to perform simulations on.
If you want to test your program not only in simulation but also with a real robot, you can connect it to the Open Roberta Lab.
The Help menu is linked to the Open Roberta Wiki. In addition, the following further sub-menus are available:

show welcome note again
If you click on this submenu the starting welcome note will be shown again. There the most recent innovations about the latest release of the Open Roberta Lab are listed.
Showing all your actions that done within the Open Roberta Lab.
Here you will find a detailed description of all blocks that exist for your robot system. The button for this is located on the right side of the programming environment.
The Open Roberta lab is being translated in more and more languages. Choose the language in which the program shall be displayed.
Help information is currently only available in English and in German. If you select a non-German language the help information is in English.
Open Roberta Sim
The Open Roberta simulation environment lets you test your programs. This is very useful if there is no real robot at hand.
Open Roberta programs may be run on real robots or in the simulation environment. In the simulation there is (currently) just a simple 2D robot model available. Possibly not all programming commands may be performed.
