In recent years, soft robotics has developed considerably, especially since the year 2018 when it became a hot field among current research topics. The attention that this field receives from researchers and the public is marked by the substantial increase in both the quantity and the quality of scientific publications. In this review, in order to create a relevant and comprehensive picture of this field both quantitatively and qualitatively, the paper approaches two directions. The first direction is centered on a bibliometric analysis focused on the period 2008–2022 with the exact expression that best characterizes this field, which is “Soft Robotics”, and the data were taken from a series of multidisciplinary databases and a specialized journal. The second direction focuses on the analysis of bibliographic references that were rigorously selected following a clear methodology based on a series of inclusion and exclusion criteria. After the selection of bibliographic sources, 111 papers were part of the final analysis, which have been analyzed in detail considering three different perspectives: one related to the design principle (biologically inspired soft robotics), one related to functionality (closed/open-loop control), and one from a biomedical applications perspective.

This work aims to identify the effects that a series of environmental factors, specific to the industrial conditions, have on the materials in the structure of soft robots and, therefore, on soft robotics systems. The purpose is to understand the changes in the mechanical characteristics of silicone materials, with the aim of transferring soft robotics applications from the sphere of services in the industrial field. Distilled water, hydraulic oil, cooling oil, and UV rays are the environmental factors considered in which the specimens were immersed/exposed for 24 h according to ISO-62/2008. The analysis was carried out on two of the most widely used materials in the field, belonging to the category of silicone rubber, which were subjected to uniaxial tensile tests on the strength testing machine Titan 2 Universal. The results show that the greatest impact on the characteristics of the two materials was when exposed to UV rays, while the other media tested had relatively little impact on the mechanical and elastic properties (tensile strength, elongation at break, and tensile modulus) of these materials.

A crucial aspect that has to be considered in all fields and, especially, in smart farming, a rapidly developing industry, is maintenance. Due to the costs generated by both under-maintaining and over-maintaining the components of a system, a balance has to be achieved. The paper is focused on presenting an optimal maintenance policy used to ensure cost minimization by determining the optimal time to make a preventive replacement of the actuators of a harvesting robotic system. First, a brief presentation of the gripper with Festo fluidic muscles used in a novel way instead of fingers is given. Then, the nature-inspired optimization algorithm, as well as the maintenance policy are described. The paper also includes the steps and the obtained results of the developed optimal maintenance policy applied for the Festo fluidic muscles. The outcome of the optimization shows that a significant reduction in the costs is obtained if one performs a preventive replacement of the actuators a few days before the lifetime provided by the manufacturer and the lifetime estimated using a Weibull distribution.

Virtual reality (VR) technologies have gained increasing attention in the field of physical rehabilitation due to their potential to enhance patient engagement and provide adaptive, feedback-rich environments. In this study, we report on the development and preliminary evaluation of a VR-based rehabilitation application aimed at improving upper extremity function, including muscle strength, endurance, and joint mobility. The application delivers a structured set of interactive exercises designed to support recovery through engaging, gamified tasks with real-time performance feedback and scalable difficulty levels. A pilot usability study was conducted with a cohort of target users to assess the system’s practicality, therapeutic relevance, and user satisfaction. Qualitative data were collected to evaluate usability, effectiveness, and areas for further improvement. Preliminary results suggest that the VR application is usable, accessible, and well-received by users, with high levels of engagement reported throughout the intervention. Participants also provided constructive feedback, emphasizing the potential benefits of incorporating enhanced sensory feedback mechanisms to improve immersion and therapeutic impact. These initial findings support the viability of VR-based rehabilitation tools and provide a foundation for future clinical studies aimed at validating their efficacy in diverse patient populations.

The actual demographic studies show that number of the elderly people is increasing constantly. Considering their motor, sensorial and cognitive constrains and restrictions, a new field of Assistive Technology is developing, focussed on the design and development of a wide range of devices, apparatus, equipment and systems dedicated to their independent and safe life. In this paper, a systematisation of existing gero-technical systems is proposed, emphasising the today trends in this field. The specific issues of designing this kind of products are identified and analysed. Two approaches of the authors are finally presented: wearable suits for aging and disabilities simulation and tele-monitoring of the elderly.
