Special Issue Information

Dear Colleagues,

Soft robotic technologies are paving the way toward robotic abilities which are vital for a wide range of applications, including manufacturing, manipulation, gripping, human–machine interaction, locomotion, wearable technologies and many more. These also offer soft robotics wide application prospects in the fields of industrial production, defense military, medical, exploration with integration of Internet of Things (IoT) and Artificial Intelligence (AI). Soft robots are of notable interest because, unlike their rigid counterparts, they can easily deform while remaining mechanically resilient, and are able to adapt to the outer environment without harm to humans, providing necessary force as actuators and/or obtain vital signals as sensors.

An essential component in a soft robot is the soft actuator which provides the system with a deformable body and allows it to interact with the environment to achieve a desired actuation pattern, such as locomotion. As a result, soft actuators that respond to various stimuli and show large deformations in addition to mechanical resilience are crucial. These would be particularly promising for application in artificial muscles, microrobots, and micro-manipulators. Soft sensing means are also another branch of soft robotics with great potential in robotic applications, such as wearables to monitor biosignals while residing dynamically on diverse surfaces.

This Special Issue focuses on recent frontier studies of soft robotics as potential and/or readily available candidates for industrial applications in advanced manufacturing, healthcare, food and beverage handling, entertainment, logistics and construction. Some of these applications include, but are not limited to, novel surgical tools (i.e., in minimally invasive surgery), soft grippers (i.e., in food handling, packaging, agricultural harvesting, soft human tissue handling), exoskeletons (i.e., in rehabilitation, as assistive in logistic wearables, medical, defense and construction), soft haptics (i.e., in teleoperation, e-commerce, gaming along with AR/VR/MR, IOT, rehabilitation) and many more, which creates another challenge to securely manage the data collected.

This Special Issue aims to shed light on the challenges in the of development of “softer and smarter” robotic systems to meet industrial demands which may be integrated with IoT and AI-based technologies towards Industry 5.0.

Soft robotics research has rapidly incorporated Additive Manufacturing (AM) into its standard prototyping repertoire. While numerous publications have highlighted the suitability of AM for producing soft pneumatic actuators, fluidic components, and lightweight structures, their integration into an industry-like robotic arm has not yet been shown. Against this background, a pneumatically actuated robot was developed that incorporates additively manufactured soft structures into rigid articulated hinges that generally allow for integration into today’s industrial production lines. The development of the robot, including pneumatic soft rotary bellows and rotary vane actuators (RVAs), is summarized, and its functionality is proven. It was found that using AM can increase the structural stiffness of robot links to a significant degree as manufacturing-related constraints in topology optimization are largely eliminated. Moreover, it was found that multi-material polyjet printing of soft rotary bellows actuators allows for highly integrated designs that provide low leakage and friction. However, these soft rotary actuators are still inferior in terms of endurance and performance if compared to AM replicas of RVAs. Our work narrows the gap between soft robotics research and today’s industrial applications, may realign research directions, and may provide impulses for the industry towards soft robotics and AM.
