Un gruppo di ricercatori del Politecnico di Losanna ha annunciato oggi, mercoledì, di essere riuscito a creare un robot in grado di replicare il movimento delle vertebre della spina dorsale.
Gli scienziati, sulla base di riprese a raggi X e con l'aiuto della tecnologia di stampa 3D, hanno ricreato una salamandra meccanica (chiamata "Pleurobot") in grado di nuotare e camminare propio come una vera (guarda il video), a un livello di dettaglio mai raggiunto sinora.
Il piccolo animaloide è mosso da 27 motorini e 11 segmenti della colonna vertebrale, mentre l'anfibio reale ne può vantare una quarantina. La sua morfologia ricalca quella delle prime forme di vita terrestri e, quindi, dal punto di vista dell'evoluzione, anche quella degli esseri umani.
