Soft robotics at home.
Matthew Borgatti of HAR.MS made this slightly disconcerting yet undeniably fascinating prototype of an air-powered robotic tentacle. The tentacle itself is made of silicone, and an Arudino and three solenoid valves control the flow of air that make the tentacle bend and twist. Borgatti also made a simple visual user interface with Processing to operate it.
“Soft robotics” like this have several potential advantages over the more traditional “hard” systems. A soft arm is more gentle with far fewer moving parts, and is, in some ways, more resistant to damage that a typical robotic arm.
