EAP strands consist of EAP tiles and actuators. Segments of actuators control specific tiles or tile groups to generate motion.
Some snakes can make themselves and stand by simultaneously tensing opposite muscles on 'lever' ribs. Here, pairs of overlapping EAP tiles make the braid go rigid when activated in opposite directions.
Adjusting the timing, direction, and voltage to an EAP structure allows a multitude of shapes and movements.
Individual EAP strands can only exert force in one dimension, but braids cooperatively generate forces in 3D.
