Africa-Press – C\u00f4te d’Ivoire. <\/strong><\/span>L\u2019e\u0302tre humain est ge\u0301ne\u0301ralement assez fier de son pouce opposable, qui lui procure un beau sentiment de supe\u0301riorite\u0301 sur les autres espe\u0300ces. Sauf que le principe a des limites. Une e\u0301quipe de chercheurs en ge\u0301nie me\u0301canique et en robotique de l’Ecole polytechnique fe\u0301de\u0301rale de Lausanne (EPFL, Suisse) est en tout cas partie de ce constat pour concevoir une main robotique bien plus habile qu\u2019une main humaine.<\/p>\n

Le projet est de\u0301taille\u0301 dans un article de Nature en janvier 2026. Il consiste en une structure ronde faisant office de paume et autour de laquelle sont dispose\u0301s quatre, cinq ou six doigts de tailles identiques, l\u2019extre\u0301mite\u0301 de la dernie\u0300re phalange e\u0301tant couverte d\u2019un embout en silicone garant d\u2019une pre\u0301hension efficace.<\/p>\n

Opposables les uns aux autres<\/b><\/p>\n

Premie\u0300rement, au lieu d\u2019e\u0302tre tous opposables au pouce, ces doigts sont capables de pivoter de manie\u0300re a\u0300 e\u0302tre tous opposables les uns aux autres, comme on peut le voir de\u0300s le de\u0301but de la vide\u0301o de de\u0301monstration ci-dessous.<\/p>\n

Ensuite, les articulations des phalanges sont re\u0301versibles, permettant un mouvement du doigt a\u0300 90 degre\u0301s dans un sens et a\u0300 90 degre\u0301s dans l\u2019autre. C\u2019est-a\u0300-dire que les doigts peuvent se plier de manie\u0300re parfaitement syme\u0301trique sous ou au-dessus de la paume (laquelle est en fait a\u0300 la fois la paume et le dos de la main).<\/p>\n

Re\u0301sultat: cette main robotique peut ope\u0301rer plusieurs actions de pre\u0301hension simultane\u0301es en sollicitant plusieurs jeux de doigts inde\u0301pendamment, et ce d\u2019un me\u0302me co\u0302te\u0301 ou des deux co\u0302te\u0301s de la paume. Un humain, lui, aurait besoin de ses deux mains ou de prendre successivement un objet puis un autre.<\/p>\n

Les limitations du bras humain<\/b><\/p>\n

Mais le projet ne s\u2019arre\u0302te pas la\u0300. \u00ab\u00a0La main est fixe\u0301e au bout du bras, ce qui restreint sa mobilite\u0301 et limite l\u2019espace auquel elle peut acce\u0301der\u00a0\u00bb, explique l\u2019e\u0301quipe de l’EPFL dans son article de recherche. C\u2019est la raison pour laquelle, par exemple, aller chercher des objets sous un meuble n\u2019est pas toujours facile. L\u2019ide\u0301al serait d’avoir une main de\u0301tachable qui puisse aller ou\u0300 elle veut… Et c\u2019est exactement ce que les chercheurs ont de\u0301veloppe\u0301 !<\/p>\n

Leur main robotique peut se de\u0301solidariser du bras articule\u0301 qu\u2019elle termine. Elle tombe a\u0300 plat sur le sol puis les doigts se plient et s\u2019actionnent pour lui permettre de se de\u0301placer. Les chercheurs se sont inspire\u0301s d\u2019animaux comme la pieuvre qui utilise ses bras aussi bien pour attraper des coquillages que pour avancer sur le sol marin. De la me\u0302me manie\u0300re, les doigts de la main prennent les faux airs de pattes d\u2019araigne\u0301e pour aller saisir en bout de course un objet et revenir se rattacher au bras.<\/p>\n

Potentielle prothe\u0300se<\/b><\/p>\n

Les limites e\u0301nonce\u0301es pour une main humaine sont en fait valables pour un robot industriel: un syste\u0300me pre\u0301hensile est lui aussi limite\u0301 par le fait d\u2019e\u0302tre fixe\u0301 a\u0300 un bras articule\u0301 et par son rayon d\u2019action. Le nouveau concept de l’EPFL pourrait donc e\u0302tre applique\u0301 dans des machines en usine, dans des entrepo\u0302ts.<\/p>\n

Mais l\u2019e\u0301quipe voit encore un autre usage, comme le dit l\u2019article: \u00ab\u00a0Me\u0302me si cette main robotique n\u2019est pas anthropomorphe, nous n\u2019excluons pas une potentielle adaptation pour servir de prothe\u0300se. En outre, son design offre des possibilite\u0301s en matie\u0300re d\u2019applications de membre augmente\u0301.\u00a0\u00bb<\/p>\n
