“…Another application of bioinspired dry adhesives is adhesive patches for pick-and-place systems. The flexibility and softness of bioinspired dry adhesives enable precise gripping and placing actions performed by a mechanical device, while also preventing any potential damage that may be caused by a rigid gripper to the object being picked up [214][215][216][217][218]. A wealth of research has been conducted in this field by Zhu et al Specifically, the hybrid design inspired by the human finger, which incorporates a rigid-soft coupling structure, exhibits a broad output force range, exceptional flexibility, and commendable stability [217].…”

In the early twenty-first century, extensive research has been conducted on geckos’ ability to climb vertical walls with the advancement of microscopy technology. Unprecedented studies and developments have focused on the adhesion mechanism, structural design, preparation methods, and applications of bioinspired dry adhesives. Notably, strong adhesion that adheres to both the principles of contact splitting and stress uniform distribution has been discovered and proposed. The increasing popularity of flexible electronic skins, soft crawling robots, and smart assembly systems has made switchable adhesion properties essential for smart adhesives. These adhesives are designed to be programmable and switchable in response to external stimuli such as magnetic fields, thermal changes, electrical signals, light exposure as well as mechanical processes. This paper provides a comprehensive review of the development history of bioinspired dry adhesives from achieving strong adhesion to realizing switchable adhesion.

“…Manipulation, which plays a pivotal role in the realm of robotics [ 4 ], constitutes an emerging and intricate field. In contemporary times, several materials, actuators, and fabrication techniques have been employed to develop grippers [ 5 , 6 , 7 ]. Within the landscape of prior research, robotic grippers can be broadly categorized into two principal groups: the traditional/conventional variety and soft grippers, both of which draw inspiration from natural mechanisms.…”

The autonomous manipulation of objects by robotic grippers has made significant strides in enhancing both human daily life and various industries. Within a brief span, a multitude of research endeavours and gripper designs have emerged, drawing inspiration primarily from biological mechanisms. It is within this context that our study takes centre stage, with the aim of conducting a meticulous review of bioinspired grippers. This exploration involved a nuanced classification framework encompassing a range of parameters, including operating principles, material compositions, actuation methods, design intricacies, fabrication techniques, and the multifaceted applications into which these grippers seamlessly integrate. Our comprehensive investigation unveiled gripper designs that brim with a depth of intricacy, rendering them indispensable across a spectrum of real-world scenarios. These bioinspired grippers with a predominant emphasis on animal-inspired solutions have become pivotal tools that not only mirror nature’s genius but also significantly enrich various domains through their versatility.

In this research, it is aimed to present a comparative analysis of soft–rigid industrial parallel rigid grippers to compare their technical capabilities and assess the potential for soft–rigid grippers to address the challenge of grasping fragile objects with various shapes and sizes. In this research, 24 soft–rigid grippers are first identified through a scoping review using the Web of Science database, capturing their technical features and performance. Providing a variable stiffness grasp (n = 9, 37.5%) and a limited grasp capability (n = 8, 33.3%) is the most common advantage and challenge, respectively, of soft–rigid grippers. Pneumatic actuators (n = 12, 50.0%), followed by tendon‐driven electric rotary actuators (n = 9, 37.5%), are the predominant actuators used for soft–rigid grippers. Soft–rigid grippers are found to have a lower output force‐to‐weight ratio (n = 9, median , standard deviation (σ) = 15.17) in comparison to industrial parallel rigid grippers (n = 63, , ), but can provide a larger range of motion (n = 20, , ). This is the first quantitative comparative analysis between industrial parallel rigid and soft–rigid grippers, enhancing the understanding of their status and prospects in industrial applications. Herein, a common approach is proposed to standardize reporting to facilitate benchmarking between research‐based and industrial grippers and highlight controlling soft–rigid grippers is an underexplored area that can enhance the technology's performance.
