context_page_description: Open Roberta is the name of a project within the German education initiative "Roberta—Learning with robots", initiated by Fraunhofer IAIS, which is an institute belonging to the Fraunhofer Society. With Open Roberta Fraunhofer IAIS is looking to encourage children to code by using robots such as Lego Mindstorms, and other programmable hardware systems such as Arduino, BBC micro:bit, and the Calliope mini. The Cloud-approach of the Open Roberta Lab is intended to simplify programming concepts and make it easier for teachers and schools to teach how to code. Open Roberta is free and does not require any installation. The project was initially founded with €1Mio by Google.org.
context_section_description: Since version beta 1.3.0 the Open Roberta Lab also offers a simulation environment. This is a simulation of a two-dimensional robot model equipped with two wheels (differential drive). To program the simulated robot also the programming language NEPO may be used. The simulated 2D model includes the simulation of an ultrasonic sensor, a touch sensor, a color sensor and the display of an LED. In addition, different environments can be chosen. Since version beta 1.4.0 NEPO blocks can used without any changes for the 2D-Simulation and the real robot.
