Fig. 1: Dexterous soft robots.
From: Dexterous electrical-driven soft robots with reconfigurable chiral-lattice foot design
a The soft robot moves in the right direction under a low-frequency voltage as the flat foot jumps above the ground. b The soft robot moves in the left direction under a medium-frequency voltage as the chiral-lattice foot bounces above the ground due to dynamic behaviors. c The soft robot moves in a circular direction at a high-frequency voltage due to resonant and chiral twisting effects. d The shape memory effect is combined with the chiral-lattice design method to realize complex functions such as forming an S-shaped trajectory. e The soft robot consists of a dielectric elastomer artificial muscle as its deformable body and a pair of asymmetric feet: a flat foot and a chiral-lattice foot.
