... of objects of various shapes. In this study, an energy-efficient gripper was developed to accommodate both convex and concave shapes using a tristable structure that combines two bistable structures, with shape memory alloy wires used as actuators. Different gripping modes were designed for convex...

...). This paper proposes a shape memory alloy driven robot capable of using a reciprocating motion to crawl over a surface without any use of electronic controller. A mechanical logic switch is designed to determine the activation timing for a pair of antagonistic shape memory alloy (SMA) actuators. Meanwhile...

...Yonas Tadesse; Dennis Hong; Shashank Priya A biped mountable robotic baby head was developed using a combination of Biometal fiber and Flexinol shape memory alloy actuators (SMAs). SMAs were embedded in the skull and connected to the elastomeric skin at control points. An engineered architecture...
