This research in Human Computer Interfaces combines different fields such as robotics, computer sciences , cognitive sciences, ergonomics and design. In partnership with 25 high schools in Nouvelle Aquitaine, the project is made to be flexible to the requirements of ISN (Informatique et Sciences du Numérique) or computer sciences courses and be a modular tool for teaching and learning basics of coding and robotics. It is made to be simple but also customizable. Users can find resources online and share their projects to the community. So far several studies have been leaded about Poppy Ergo Jr : the usability of the robot [Desprez et al., 2018b], the impact on how people perceive robots with the Euro382 test [Eurobarometer, 2012] and comparison with another robot, the Thymio [not published yet].
