3D-printed ‘soft’ robotic tentacle displays new level of agility
15 October 2015
Cornell University engineers have developed a method to re-create the arrangement of muscles of an octopus tentacle, using an elastomer and 3D printer.
The research was ground-breaking as hitherto, 3D printing methods could not directly print a soft robotic device with as much agility and degree of freedom as the new method provides, according to Rob Shepherd, assistant professor of mechanical and aerospace engineering and senior author of the study, published in the journal Bioinspiration & Biomimetics.
The research team developed the mechanical design using a digital mask projection stereolithgraphy system for the 3D printing of soft actuators.
“Based on the demonstration reported here and the possibilities for improved materials, this nascent printing process for soft actuators is a promising route to sophisticated, biomimetic systems,” says Shepherd.
