Soft robotics is a rapidly evolving field where robots are fabricated using highly deformable materials and usually follow bioinspired design. Their high dexterity safety makes them ideal for applications such as gripping, locomotion, biomedical devices, the environment dynamic sensitive to physical interaction. Pneumatic actuation remains dominant technology in soft due its low cost mass, fast response time, easy implementation. Given significant number of publications over recent years, newcomers even established researchers may have difficulty assessing state art. To address this issue, article summarizes development pneumatic actuators up until date publication. The scope includes design, modeling, fabrication, actuation, characterization, sensing, control, robotic devices. In addition historical overview, there special emphasis on advances novel designs, differential simulators, analytical numerical modeling methods, topology optimization, data-driven control hardware boards, nonlinear estimation techniques.

Abstract Miniature soft robots are mobile devices, which made of smart materials that can be actuated by external stimuli to realize their desired functionalities. Here, the key advancements and challenges locomotion producible miniature in micro‐ centimeter length scales highlighted. It is highly desirable endow these small machines with dexterous locomotive gaits as it enables them easily access confined enclosed spaces via a noninvasive manner. If able capitalize this unique ability, they will have potential transform vast range applications, including but not limited to, minimally invasive medical treatments, lab‐on‐chip search‐and‐rescue missions. The categorized into terrestrial, aquatic, aerial locomotion. Except for centimeter‐scale perform locomotion, discussions report centered around millimeter scales. Under each category prospective methods strategies improve gait performances also discussed. This provides critical analyses inspire future make significantly more agile.

Abstract Soft robots are, due to their softness, inherently safe and adapt well unstructured environments. However, they are prone various damage types. Self‐healing polymers address this vulnerability. soft can recover completely from macroscopic damage, extending lifetime. For developing healable robots, formative additive manufacturing methods have been exploited shape self‐healing into complex structures. Additionally, several novel techniques, noted as (re)assembly binding techniques that specific polymers, created. Herein, the wide variety of processing for robotics available in literature is reviewed, limitations opportunities discussed thoroughly. Based on defined requirements these critically compared validated. A strong focus drawn reversible covalent (physico)chemical cross‐links present do not only endow healability resulting robotic components, but also beneficial many techniques. They solve current obstacles including formation robust multi‐material parts, recyclability, stress relaxation. This review bridges two promising research fields, guides reader toward selecting a suitable method based polymer intended application.
