Abstract

Dans divers modes de réalisation, un dispositif assisté par ordinateur comprend un effecteur terminal ayant une première mâchoire, une seconde mâchoire et au moins un transducteur pour délivrer de l'énergie à ultrasons à l'aide d'au moins une parmi la première mâchoire et la seconde mâchoire, et un système de traitement couplé à l'effecteur terminal, le système de traitement étant configuré pour commander la première mâchoire et la seconde mâchoire pour saisir un matériau, déterminer une ou plusieurs premières caractéristiques de la préhension, commander une première énergie délivrée par l'au moins un transducteur pour sceller le matériau sur la base de la ou des premières caractéristiques, et en réponse à l'achèvement du scellement du matériau, commander au moins une seconde énergie délivrée par l'au moins un transducteur pour couper le matériau saisi sur la base de la ou des premières caractéristiques.
