![]() They can also be combined with other components, for example, electrical components, to increase their functionality. These soft actuators can manipulate objects with moderate performance for example, they can lift loads up to 120 times their weight. Paper, when used to introduce anisotropy into elastomers, can be readily folded into 3D structures following the principles of origami these folded structures increase the stiffness and anisotropy of the elastomeric actuators, while being light in weight. The ultra-soft gripper is the latest innovation in soft robotics for underwater sampling, an ongoing collaboration between Gruber and Wood that has produced the origami-inspired RAD sampler and multifunctional squishy fingers to collect a diverse array of hard-to-capture organisms, including squids, octopuses, sponges, sea whips, corals. This class of structure is versatile: the same principles of design lead to actuators that respond to pressurization with a wide range of motions (bending, extension, contraction, twisting, and others). They are inexpensive, simple to fabricate, light in weight, and easy to actuate. L Mahadevan delves into the world of origami, from its origins in natural patterns to creations in art, from understanding it using mathematics to its deployment in technology. ![]() ![]() On pneumatic inflation, these actuators move anisotropically, based on the motions accessible by their composite structures. Sep 2018 Okinawa Institute of Science and Technology Graduate University Presidential Lecture Series Prof. Abstract The development of soft pneumatic actuators based on composites consisting of elastomers with embedded sheet or fiber structures (e.g., paper or fabric) that are flexible but not extensible is described.
