Soft Tentacles

Design: The model consists of two tentacles and a base. The tentacles curl up when the cables are pulled. The tentaclesThis model is designed based on our latest research results in soft robotics.Paper link: https://www.cell.com/device/fulltext/S2666-9986(24)00603-3 We observed that despite their large diversity in terms of size (e.g., from centimeters to meters), anatomy (e.g., pure muscular or combination of skeleton and muscles), and living environment (e.g., on land or in water), several animal appendages share a commonality: a tightly packed shape that conforms to a logarithmic spiral (see figure on the right). This paper introduces a new class of soft robots that replicate the spiral pattern. The proposed design enables lifelike movements through simple cable actuation. The baseThere are two types of bases.1. a round base that needs to be fixed on the head with a thicker cable.2. a headband that can be clipped on the head.
