Africa-Press – Tchad. <\/strong><\/span>Un TABV est un drone roulant capable dans certaines circonstances de s\u2019e\u0301lever dans les airs. D\u2019ou\u0300 cet acronyme pour \u00ab\u00a0terrestrial and aerial bimodal vehicle\u00a0\u00bb.<\/p>\n

Une e\u0301quipe chinoise en technologies de contro\u0302le industriel de l\u2019universite\u0301 du Zhejiang travaille sur un tel projet depuis 2021. Les derniers re\u0301sultats ont e\u0301te\u0301 pre\u0301sente\u0301s en mars 2024 sur la plateforme Arxiv: une machine de 910 grammes et de 23 centime\u0300tres de large. Il s\u2019agit fondamentalement d’un drone roulant qui ne s\u2019envole que lorsque le terrain l\u2019y oblige.<\/p>\n

Deux roues et quatre rotors<\/b><\/p>\n

L\u2019engin est muni de deux larges roues late\u0301rales passives et de quatre rotors. Ces derniers permettent le vol mais servent aussi de propulseurs quand le drone est au sol. Outre la batterie embarque\u0301e, une came\u0301ra ste\u0301re\u0301oscopique et un ordinateur de bord avec un syste\u0300me de capture de mouvement servent a\u0300 analyser le terrain pour ensuite calculer une trajectoire.<\/p>\n

Une autonomie plus grande que celle d’un drone volant<\/b><\/p>\n

Les chercheurs ont multiplie\u0301 les tests. En conditions re\u0301elles, sur un sol de terre ine\u0301gal ou\u0300 un talus de gravier se dresse devant le drone, et en salle, sur un espace de 50 me\u0300tres sur 50 me\u0300tres rempli d\u2019obstacles. Sur des trajets d\u2019une longueur moyenne de 76,8 me\u0300tres, le drone a re\u0301ussi sa course dans 94% des cas. Surtout, les chercheurs se sont rendu compte qu\u2019en mode roulant, il consommait un septie\u0300me de la quantite\u0301 d\u2019e\u0301nergie ne\u0301cessaire pour voler.<\/p>\n

Ce qui augmente nettement l\u2019autonomie compare\u0301 a\u0300 un drone volant, alors me\u0302me que cet engin gagne en rayon d’action. Les prochains travaux vont consister a\u0300 tester le syste\u0300me sur des terrains plus difficiles et adapter la technologie a\u0300 des drones configure\u0301s diffe\u0301remment afin de ve\u0301rifier que le syste\u0300me de contro\u0302le et de navigation peut e\u0302tre ge\u0301ne\u0301ralise\u0301 efficacement.<\/p>\n
