This review covers recent advancements in the field of bioinspired soft robotics, with a primary focus on the last 4 years (2017)(2018)(2019)(2020). The review serves as a toolbox for an interdisciplinary audience interested in the most recent bioinspired soft robotic technologies. In particular, it highlights and explores the vital components of soft robots, focusing on the enabling mechanisms and their biological inspirations. The first section discusses the materials used to fabricate soft bio inspired robots. Soft bioinspired actuation and sensing are then discussed, exploring their capabilities and implementation by researchers. Existing challenges and future potentials of bioinspired soft robots are addressed in the concluding remarks. This review provides engineers and scientists with the latest technological advancements and information needed for designing and developing the next generation of soft bioinspired robotic systems. The future applications of these robots will be grand and limitless. Materials Used for Bioinspired Sensors and ActuatorsClassical robotic systems are comprised of rigid bodies, actuators, and sensors. Unfortunately, many of these well-developed actuators and sensors are not transferable to soft bodies. Thus, researchers working in soft robotics need to reinvent actuators and sensors for soft moving bodies. Biological organisms can be an excellent inspiration for designing these soft actuators and sensors, allowing for their integration in both soft and rigid bodies. The design process of soft actuators and sensors have to be initiated with material selection and composition, for they are foundations upon which the actuators and sensors will be built around. Presently, a diversified list of materials has been used in the development of soft robotic systems. This section will cover some of the latest advancements in the last 4 years in the area of material selection and composition for the design and development of soft bioinspired actuators and sensors.During the past 4 years, researchers have produced soft bioinspired actuators and sensors using biological material such as muscle tissue, [23,24] and plant fibers; [25] carbon-based materials such as graphite and graphene oxide (GO) [26][27][28][29][30][31] and carbon nanotubes (CN); [32,33] hydrogel materials such as poly(Nisopropylacrylamide) (PNIPAM), [34,35] liquid crystal elastomers (LCE), [36] dielectric elastomers (DE), [37] and ionic polymermetal composites (IPMC). [38] An overview of these materials (Figure 1), along with their underlying mechanisms, are discussed below.Biological systems can perform complex tasks with high compliance levels. This makes them a great source of inspiration for soft robotics. Indeed, the union of these fields has brought about bioinspired soft robotics, with hundreds of publications on novel research each year. This review aims to survey fundamental advances in bioinspired soft actuators and sensors with a focus on the progress between 2017 and 2020, providing a primer for the materials used i...

“…To generate friction difference, several carbon‐based actuators are designed using an unsymmetrical robot body, such as different original contact angles between two ends with the ground. [ 89,95 ] Figure a shows the forward motion mechanism. The component force of bending force to the two ends of the robot body was different because of the contact angle difference, inducing the pressure N difference to the ground.…”

Recently, the optical field driving mechanism is emerging in the manipulation of small‐scale soft robots due to its remote, wireless, and selective control capabilities. Among the light‐responsive materials, carbon has exhibited great potentials as light‐driven actuators due to its good light absorption ability, thermal conductivity, and mechanical strength. Taking advantage of the carbon materials, various carbon‐based actuators are reported with efficient, fast response, and stable actuating performance. Hence, carbon‐based actuators are widely applied in robotic applications controlled by external light irradiation. This review summarizes the principle actuating mechanism of carbon‐based actuators and focuses on the analysis of the robotization and application mechanisms. The locomotion implemented by the carbon‐based actuators is discussed by analyzing the robot structure designs and light exposing approaches, accompanied with corresponding force analysis. Moreover, various applications of carbon‐based actuators are reviewed with mechanism discussion. Furthermore, the challenges, including the perspectives of the robotization and applications of carbon‐based actuators, are discussed for further development and robotic utilization of carbon‐based materials.

“…Outer-curved surface crawlers relied on gripping mechanisms to demonstrate crawling behavior while also indicating their grippers' fixed grasping range [11], [25], [26]. Moreover, some of these robots were either large and bulky [20], [36], or developed as prototypes to demonstrate the design concepts and hence required further development for real-world deployment [7], [9], [11], [14], [16], [17], [23], [25], [27], [29], [30], [35]. Recent works based on advancements in soft robotics may help to achieve a more effective design solution [14].…”
