With the RALL-E project, Alelo, in cooperation with the RoboKind and Virginia Department of Education, is investigating how to design simulation-based learning experiences for language learning that optimize learner motivation and promote conversational skills. They are doing this by developing a prototype lifelike robot that engages in conversations in foreign language and studying its use in educational settings.
