“…However, our model does not describe the details of the physiology, connectivity, and activity of these neural circuits [45,46]. From a mechanical standpoint, our model neglects many of the complications in sea stars, including details of the tube feet biomechanics as muscular hydrostats [21,32,47] and deformations along the arms [48][49][50][51][52]. Another limitation of this study is that it considers a two-dimensional model to study locomotion in one dimension.…”

“…Furthermore, the inherent dexterity of soft materials empowered bioinspired propulsion, paving the way for novel navigation techniques achievable for soft robots 17,18,36,38,43,[56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71][72][73][74] (Fig. 5A-F, K).…”

“…They have an interesting locomotion mechanism which enables them to move along various kinds of underwater terrain. [ 145 ] They have a spherical body with tube shaped feet and spines on the outside. The spines are used primarily for protection but may support locomotion and attachment as well.…”

“…An untethered, 40 cm in diameter, sea urchin inspired robot was built using soft hydraulic actuators. [ 145 ] It contained five bioinspired tube feet with an aspect ratio of 1:6 and only ten rigid spines, compared to thousands of spines in adult sea urchins. Permanent magnets were used as adhesive pads.…”
