New Scientist TV: Frankenoctopus unveils novel shape-shifting arms: The first prototype, currently on display at the Science Museum in London, has six silicone legs designed for locomotion, while two specialised arms use artificial muscles, motors and sensors to detect and grasp objects. A spring-like structure inside these tentacles, made from a shape-memory alloy, can expand, contract or bend in any direction with changes in temperature.
Cecilia Laschi of Sant'Anna School of Advanced Studies in Pisa, Italy, and colleagues control their robot's behaviour via a centralised unit that mimics the central nervous system of an octopus.
