Thymio and Mobsya fork

Thymio is an educational robot which goal is to let children discover programming. Mobsya is a non-profit association which goal is to create products and service to help children to discover digital technology and sciences. It is at the heart of Thymio's development and takes care of its production and distribution.

Up to April 2018, Mobsya was working as part of the Aseba community in the Aseba repository to develop Thymio software tools in an integrated manner. After this date, Mobsya decided to fork the Aseba repository and to keep developping Thymio software tools in its own repository.
