A Fully Soft Bionic Grasping Device with the Properties of Segmental Bending Shape and Automatically Adjusting Grasping Range

Actuated Palms for Soft Robotic Hands: Review and Perspectives

“…While previously cited papers used electric motors to reconfigure fingers and change the gripper workspace, other works adopted pneumatic actuators for the same purpose [18], [72], [73]. The authors in [18] and [72] proposed two similar grippers in which pneumatic actuators in the palm move the fingers' bases allowing their rotation and translation.…”

“…Two of the fingers also have an actuator that allows the rotation of the finger around its main axis. Gai et al [73] proposed a two-fingered soft gripper endowed with a special "bracket structure," which is a soft pneumatic actuator connecting two soft fingers. The bracket works as an actuated palm and can be bent in two directions depending on whether it is inflated or vacuum is applied.…”

Human Pulse Detection by a Soft Tactile Actuator

“…Finally, as shown in Figure 5, the tactile stress sensor was fixed on the formed finger using the cured silica gel as the sensor fixing layer to fabricate the tactile physiotherapy finger. Remark: Injection molding is a simple and effective method to fabricate various pneumatic devices [19]. In the above manufacturing of the tactile physiotherapy finger, injection molding was employed.…”

“…In [18], four pneumatic soft actuators were employed to design a soft-legged untethered quadruped robot. In [19], a fully soft bionic grasping device based on pneumatic actuation technology was used to grab objects of different shapes, such as bottles, balls, boxes, and so on. However, the aforementioned pneumatic soft actuators only focused on the actuation function, while their sensing function was not explored.…”

Design of a Bistable Artificial Venus Flytrap Actuated by Low Pressure with Larger Capture Range and Faster Responsiveness

“…Soft pneumatic bending actuators are typically representative of pneumatic actuations, which achieve bending deformation via a flexible asymmetrical axial cross-section surrounding an inflatable void. Three types of axial asymmetry have been developed for soft pneumatic bending actuators [ 47 ]: multi-material [ 48 , 49 , 50 , 51 , 52 , 53 ], corrugated membranes [ 54 , 55 , 56 , 57 , 58 , 59 , 60 ] and eccentric void asymmetries [ 61 , 62 ]. It is worth mentioning that the soft pneumatic bending actuator can not only be fabricated by traditional cast molding methods, but can also be fabricated by 3D/4D printing technologies benefiting from the recent advances in additive manufacturing technology [ 57 , 60 , 63 ].…”
