Open Roberta is a free, drag and drop, cloud-based platform for programming LEGO EV3 robots. Check it out at this link: http://www.open-roberta.org/en/welcome/ and see below for my video summary and review.
To use Open Roberta, you will need a micro SD card with an adapter and a wifi adapter (we found that the Edimax adapter works well). Using the Open Roberta Setup Wiki, follow the steps for downloading the necessary files onto the SD card. Once you have the Open Roberta files, you will be able to run the Open Roberta menu right on your EV3 Brick!
The last step is connecting your EV3 brick to a wifi network, and then typing in the Open Roberta Lab code from your EV3 brick into the Open Roberta lab on the computer. This wirelessly connects the program on the computer to your EV3 brick and allows you to create programs and run them wirelessly on your robot.
If you run into any issues or have programming questions, simply check out the extensive Open Roberta Wiki, which includes tutorials and example programs!
Programming with Open Roberta is made easy with a simple drag and drop platform that still allows users to create complex programs. Since it is all cloud based, there are no logistical issues about where to save files. Instead, students can simply save programs to their account, access them from any computer, and run them with any robot. Students can also continue working on their programs from home by simply logging in. Best of all, if your program doesn’t run as expected and you need to make changes, there is no hassle with having to plug your robot back in and download the new program. Instead, users can simply make their changes and hit run!
