“…Globally patterned textile bellows expand from planar to 3D upon inflation, with similar behavior to IPAMs, in a single patterned actuator [ 273 ] or in discrete multi‐pouch architectures [ 286 ] (Figure 9j,k). Unlike elastomeric IPAMs, these textile actuators can be pulled into a more open state if loaded and are not typically used to lift hanging loads unless actuated by vacuum.…”

Textiles have emerged as a promising class of materials for developing wearable robots that move and feel like everyday clothing. Textiles represent a favorable material platform for wearable robots due to their flexibility, low weight, breathability, and soft hand‐feel. Textiles also offer a unique level of programmability because of their inherent hierarchical nature, enabling researchers to modify and tune properties at several interdependent material scales. With these advantages and capabilities in mind, roboticists have begun to use textiles, not simply as substrates, but as functional components that program actuation and sensing. In parallel, materials scientists are developing new materials that respond to thermal, electrical, and hygroscopic stimuli by leveraging textile structures for function. Although textiles are one of humankind's oldest technologies, materials scientists and roboticists are just beginning to tap into their potential. This review provides a textile‐centric survey of the current state of the art in wearable robotic garments and highlights metrics that will guide materials development. Recent advances in textile materials for robotic components (i.e., as sensors, actuators, and integration components) are described with a focus on how these materials and technologies set the stage for wearable robots programmed at the material level.

“…To reduce cost by unifying drive sources, the support mechanism is pneumatically driven, as with the suction pads. Various pneumatic actuators have been proposed [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. McKibben-type artificial muscles [10][11][12][13][14] have the characteristic of expanding diametrically and contracting in the axial direction when pressurized.…”

“…However, pneumatic actuators that are deformed by pressure risk expansion damage unless proper control is performed. In contrast, bellows-type actuators [21][22][23][24] contract in the axial direction when decompressed and extend in the axial direction after releasing the reduced pressure state, so pressurization beyond atmospheric pressure is unnecessary. Therefore, from the viewpoint of safety, we adopted the bellows method for the pneumatic actuator used in this study.…”

Suction pad unit using a bellows pneumatic actuator as a support mechanism for an end effector of depalletizing robots

et al. 2020

This paper describes a vacuum suction-type end effector for depalletizing robots in distribution centers. The developed end effector has multiple suction pad units to which a bellows pneumatic actuator is applied as the support mechanism. Load-bearing capacity is improved due to a high-strength wire provided inside the bellows, and the contraction force is improved due to ring members placed inside of the ridges of the rubber bellows. The developed end effector is attached to the arm of a linear motion-type depalletizing robot, and its real-world performance is verified. Verification results confirm that the suction pad units tolerate cardboard box inclination and differences in box height by a simple lowering motion of the arm, and multiple cardboard boxes can be simultaneously unloaded. Moreover, as compared with conventional end effectors, the developed end effector achieves large expansion and contraction in a thin structure. The developed end effector is expected to broaden applications for depalletizing robots.

“…In contrast to the actuators in the first class, there is no fundamental physical limit on the lengthwise contraction for a given actuator length. One example of this type is a bellows textile muscle (Belforte et al, 2014 ), similar to the Peano fluidic muscle. The actuator is made of fabric and constructed by connecting a number of round discs along their edges and centers.…”

We present a high-displacement pneumatic artificial muscle made of textiles or plastics that can include integrated electronics to sense its pressure and displacement. Compared to traditional pneumatic muscle actuators such as the McKibben actuator and other more recent soft actuators, the actuator described in this paper can produce a much higher (40∼65%) contraction ratio. In this paper, we describe the design, fabrication, and evaluation of the actuator, as well as the manufacturing process used to create it. We demonstrate the actuator design with several examples that produce 120 and 300 N at pressures of 35 and 105 kPa, respectively, and have contraction ratios of 40-65%.
