Fig. 7From: Evaluation of two complementary modeling approaches for fiber-reinforced soft actuatorsThe finite element model validation. Experimental setup used to measure the rotation of FREE (left). Rotation per unit length of \(20^{\circ }\), \(40^{\circ }\), and \(70^{\circ }\) FREEs, all 130 mm in length, 9.52 mm inside diameter, and 0.8 mm wall thickness (right). The curves are the results with the finite element model and dots are experimentally measured dataBack to article page
