Erratum to: Design, characterization, and implementation of a two-DOF fabric-based soft robotic arm (IEEE Robotics and Automation Letters (2018) 3:3 (2702-2709) DOI: 10.1109/LRA.2018.2831723)

IN THE paper "Design, Characterization, and Implementation of a Two-DOF Fabric-Based Soft Robotic Arm," published in the July 2018 issue of the IEEE ROBOTICS AND AUTOMATION LETTERS, there is a missing citation in Sec. II-C. The citation should appear after the sentence "Since it is difficult to precisely model the inflation of the fabrics, we have the following assumptions" in the first paragraph of Sec. II- C on p. 2704. It is inspired by the following reference paper and should be cited as: R. F. Natividad, M. R. D. Rosario, P. C. Y. Chen, and C.-H. Yeow, "A hybrid plastic-fabric soft bending actuator with reconfigurable bending profiles," in Proc. IEEE Int. Conf. Robot. Automat., 2017, pp. 6700-6705.
