L'Universit\u00e9 de Californie \u00e0 Berkeley a publi\u00e9 le projet Berkeley Humanoid Lite, qui est le r\u00e9sultat de recherches et d'exp\u00e9rimentations dans le domaine de la cr\u00e9ation de robots humano\u00efdes faciles \u00e0 fabriquer. Le robot est construit avec des logiciels open source et se d\u00e9veloppe selon le concept de Open Hardware. Le mat\u00e9riel est compos\u00e9 de composants standard disponibles dans le commerce et de pi\u00e8ces fabriqu\u00e9es par impression 3D. Des mod\u00e8les d'apprentissage automatique, le code source du logiciel, des sch\u00e9mas, une liste de composants (BOM), un plan d'assemblage et des mod\u00e8les pour l'impression 3D ont \u00e9t\u00e9 publi\u00e9s.

Sous licence MIT, les codes sources des firmwares ex\u00e9cut\u00e9s sur le robot pour les contr\u00f4leurs d'actionneurs et la gestion du mat\u00e9riel bas niveau sont ouverts, ainsi que des composants externes, tels que l'environnement de d\u00e9veloppement des sc\u00e9narios de contr\u00f4le, l'environnement de simulation, d'entra\u00eenement des mod\u00e8les de mouvement et de v\u00e9rification, bas\u00e9 sur les frameworks Isaac Lab, Isaac Sim et MuJoCo. Des contr\u00f4leurs de r\u00e9alit\u00e9 virtuelle standard SteamVR peuvent \u00eatre utilis\u00e9s pour le contr\u00f4le \u00e0 distance.

\"Robot<\/center> <\/p>\n

Des mod\u00e8les d'apprentissage automatique utilis\u00e9s dans les exp\u00e9riences ont \u00e9t\u00e9 publi\u00e9s s\u00e9par\u00e9ment, ainsi qu'un contr\u00f4leur de locomotion, utilisant un mod\u00e8le d'apprentissage automatique par renforcement pour assurer le d\u00e9placement du robot vers un point donn\u00e9. L'utilisation du robot comme manipulateur t\u00e9l\u00e9command\u00e9 par un humain a \u00e9t\u00e9 d\u00e9montr\u00e9e. Des exp\u00e9riences sont en cours dans le domaine de la navigation autonome, de l'\u00e9vitement d'obstacles, de la reproduction de la motricit\u00e9 fine et de la coordination des mouvements lors de la marche.

Le projet peut \u00eatre utilis\u00e9 par d'autres chercheurs comme point de d\u00e9part \u00e9conomique pour explorer et mener des recherches dans le domaine de la robotique. Aucune comp\u00e9tence particuli\u00e8re n'est requise pour l'assemblage et tout le monde peut utiliser les instructions et sch\u00e9mas fournis pour cr\u00e9er son propre mod\u00e8le, en d\u00e9pensant moins de 5000 dollars. Le robot est modulaire et con\u00e7u pour pouvoir \u00eatre am\u00e9lior\u00e9 et adapt\u00e9 \u00e0 des fins personnelles, par exemple, apr\u00e8s une modification minimale, il peut \u00eatre transform\u00e9 de bip\u00e8de \u00e0 quadrup\u00e8de ou \u00e0 un robot ressemblant \u00e0 un kangourou.

Le facteur principal de la r\u00e9duction des co\u00fbts de production a \u00e9t\u00e9 l'utilisation de pi\u00e8ces en plastique fabriqu\u00e9es par impression 3D dans la conception. Les chercheurs ont d\u00fb r\u00e9soudre plusieurs probl\u00e8mes li\u00e9s \u00e0 la fiabilit\u00e9 et \u00e0 la durabilit\u00e9 des transmissions utilisant des engrenages en plastique plut\u00f4t qu'en m\u00e9tal. Ces limitations ont \u00e9t\u00e9 surmont\u00e9es gr\u00e2ce \u00e0 l'utilisation d'un r\u00e9ducteur cyclo\u00efdal.
