  • JdeRobot

    Other

    Robotics applications are typically distributed, made up of a collection of concurrent asynchronous components which communicate using some middleware (ROS messages, DDS...). Building robotics applications is a complex task. Integrating existing nodes or libraries that provide already solved functionality, and using several tools may increase the software robustness and shorten the development time. JdeRobot provides several tools, libraries and reusable nodes. They have been written in C++, Python or JavaScript.

  • MetaCall

    Programming languages

    When working with different technologies and developers of different programming languages, the productivity of the entire team worsens due to the lack of interoperability and communication between them. If the developers need two technologies which are written in different programming languages, for instance, a C/C++ library called from NodeJS, the team usually needs to port to one of the two languages or write a wrapper around them. Maintaining a port of a library or the plumbing code is frequently error-prone, time-consuming, and does not add any value to the final product.

  • Open Technologies Alliance - GFOSS

    Science and medicine

    Open Technologies Alliance (GFOSS) is a non-profit organization, with 37 Universities and Research Centers as its shareholders. Our main goal is to promote Openness. GFOSS – Open Technologies Alliance is a platform for Open Standards, Free Software, Open Content, Open Data & Open Hardware in Greece. The major Greek Universities and Research Centers participate in GFOSS – Open Technologies Alliance, while leading members of the Greek community of developers play a key role in the implementation of our policies. Through our initiatives we aspire to contribute and coordinate the efforts of groups of volunteers, public servants, university researchers and students enabling them to form the backbone of Greek FOSS development and implementation. GFOSS is one of the strategic actors for the promotion of OSS throughout Greece (see https://joinup.ec.europa.eu/sites/default/files/inline-files/OSS%20Country%20Intelligence%20Report_GR.pdf ). Many public administrations and academic institutions collaborate with GFOSS to implement open source projects and through Google Summer of Code we give the opportunity to students to actively engage in the production and the actual implementation of an open source project. GFOSS also contributes and advises on the development of various open source projects related to e-government and digital transformation in Greece (e.g. https://howto.gov.gr/ - https://forma.gov.gr/) and actively promotes the use of Open Source software and hardware in the Greek primary and secondary education through the Open Educational Technologies Competition (https://openedtech.ellak.gr/ )
