A multi-material robotic finger with integrated proprioceptive and tactile capabilities produced with a circular process

Josephine Anna Eleanor Hughes, Kai Christian Junge, Antonia Georgopoulou Papadonikolaki

When developing or designing biomimetic robotic fingers with rigid and soft components and integrated sensors, fabrication is often a bottle-neck when assembling and casting processing techniques are used. This study introduces a thermoplastic multi-materi ...
