“…Researchers are studying how various mechanisms have evolved in nature, aiming to mimic the adaptability and versatility of biological systems without necessarily replicating their exact structure [1][2][3][4]. Such robots aim to impersonate a variety of functions from the animal and plant kingdom, including the suction capabilities of octopus suction cups [5][6][7], the adhesive properties of gecko feet [8], the movement of octopus tentacles [9][10][11], the grasping mechanism found in bird claws [12], the walking gait of insects [13], or the snapping mechanism of the Venus flytrap [14,15].…”

Bioinspired and biomimetic soft grippers are rapidly growing fields. They represent an advancement in soft robotics as they emulate the adaptability and flexibility of biological end effectors. A prominent example of a gripping mechanism found in nature is the octopus tentacle, enabling the animal to attach to rough and irregular surfaces. Inspired by the structure and morphology of the tentacles, this study introduces a novel design, fabrication and characterization method of dielectric elastomer suction cups. To grasp objects, the developed suction cups perform out-of-plane deflections as the suction mechanism. Their attachment mechanism resembles that of their biological counterparts, as they do not require a pre-stretch over a rigid frame or any external hydraulic or pneumatic support to form and hold the dome structure of the suction cups. The realized artificial suction cups demonstrate the capability of generating a negative pressure up to 1.3 kPa in air and grasping and lifting objects with a maximum 58 g weight under an actuation voltage of 6 kV. They also have sensing capabilities to determine whether the grasping was successful without the need of lifting the objects.

“…Soft robots are compliant machines often fabricated from flexible materials such as silicones or thermoplasts. Recent developments enable their manufacturing via 3D printing using soft inks or flexible TPU filaments (Wehner et al, 2016;Slesarenko et al, 2018;Skylar-Scott et al, 2019;Conrad et al, 2020;Conrad et al 2021;Conrad et al 2022;Kappel et al, 2022). Most soft robots utilize compliant pneumatic actuators from flexible materials for movement (Whitesides, 2018;Esser et al, 2019a).…”

During the recent decade, we have witnessed an extraordinary flourishing of soft robotics. Rekindled interest in soft robots is partially associated with the advances in manufacturing techniques that enable the fabrication of sophisticated multi-material robotic bodies with dimensions ranging across multiple length scales. In recent manuscripts, a reader might find peculiar-looking soft robots capable of grasping, walking, or swimming. However, the growth in publication numbers does not always reflect the real progress in the field since many manuscripts employ very similar ideas and just tweak soft body geometries. Therefore, we unreservedly agree with the sentiment that future research must move beyond “soft for soft’s sake.” Soft robotics is an undoubtedly fascinating field, but it requires a critical assessment of the limitations and challenges, enabling us to spotlight the areas and directions where soft robots will have the best leverage over their traditional counterparts. In this perspective paper, we discuss the current state of robotic research related to such important aspects as energy autonomy, electronic-free logic, and sustainability. The goal is to critically look at perspectives of soft robotics from two opposite points of view provided by early career researchers and highlight the most promising future direction, that is, in our opinion, the employment of soft robotic technologies for soft bio-inspired artificial organs.
