Effective Remedy

Modular Self-Reconfigurable Robotic (MSRR) schemes are a vital remedy for the developing demand in consumer products, automations and space exploration. The wider factor of usage and self-healing capacity are some of the influencing characteristics of robot for actual-wide application whereas segmental robotics provide an effective remedy with respect to traditional robotics. Researchers have now noted different forms of application and prototyped different systems of robotics whereas concentrating on constraints such as homogeneity, configurability, energy consumption and form factor. Diversified condition of various segmental robotic remedies projected for actual-world application and usage of various actuators and sensors interfacing methods alongside physical optimization of models present potential problems whereas visualizing and identifying the advantages and disadvantages of various approaches to remedies. This research reviews the various self-reconfigurable robotic schemes with a brief overview of history and architecture of the robotic schemes. Later in this contribution, the problems in the design of hardware, control and planning algorithms, mixed hardware and software problems and in its application problems that are underway are critically evaluated with respect to modular self-reconfigurable robotics.

Modular self-reconfigurable robots present wide and unique solutions for growing demands in the domains of space exploration, automation, consumer products, and so forth. The higher utilization factor and self-healing capabilities are most demanded traits in robotics for real world applications and modular robotics offer better solutions in these perspectives in relation to traditional robotics. The researchers in robotics domain identified various applications and prototyped numerous robotic models while addressing constraints such as homogeneity, reconfigurability, form factor, and power consumption. The diversified nature of various modular robotic solutions proposed for real world applications and utilization of different sensor and actuator interfacing techniques along with physical model optimizations presents implicit challenges to researchers while identifying and visualizing the merits/demerits of various approaches to a solution. This paper attempts to simplify the comparison of various hardware prototypes by providing a brief study on hardware architectures of modular robots capable of self-healing and reconfiguration along with design techniques adopted in modeling robots, interfacing technologies, and so forth over the past 25 years.

The article provides an analysis of modern trends in building public-private partnership (PPP), gives an overview of key studies devoted to this subject in general and PPPs in the field of space activities in particular. The authors analyze the practice of public-private partnerships in the U. S. and Great Britain on the examples of specific mechanisms, their key features, advantages and disadvantages that determine the possibility of their application in different areas of government-business cooperation in the field of space exploration. In order to find possible ways for direct application or adaptation of this experience in Russia for organizing space exploration PPPs the researchers concluded that the level of high-tech production in this country is insufficient and significant administrative barriers for attracting private sector into the space industry are still present.

Cartilage is a tension- and load-bearing tissue and has a limited capacity for intrinsic self-healing. While microfracture and arthroplasty are the conventional methods for cartilage repair, these methods are unable to completely heal the damaged tissue. The need to overcome the restrictions of these therapies for cartilage regeneration has expanded the field of cartilage tissue engineering (CTE), in which novel engineering and biological approaches are introduced to accelerate the development of new biomimetic cartilage to replace the injured tissue. Until now, a wide range of hydrogels and cell sources have been employed for CTE to either recapitulate microenvironmental cues during a new tissue growth or to compel the recovery of cartilaginous structures via manipulating biochemical and biomechanical properties of the original tissue. Towards modifying current cartilage treatments, advanced hydrogels have been designed and synthesized in recent years to improve network crosslinking and self-recovery of implanted scaffolds after damage in vivo. This review focused on the recent advances in CTE, especially self-healing hydrogels. The article firstly presents the cartilage tissue, its defects, and treatments. Subsequently, introduces CTE and summarizes the polymeric hydrogels and their advances. Furthermore, characterizations, the advantages, and disadvantages of advanced hydrogels such as multi-materials, IPNs, nanomaterials, and supramolecular are discussed. Afterward, the self-healing hydrogels in CTE, mechanisms, and the physical and chemical methods for the synthesis of such hydrogels for improving the reformation of CTE are introduced. The article then briefly describes the fabrication methods in CTE. Finally, this review presents a conclusion of prevalent challenges and future outlooks for self-healing hydrogels in CTE applications.

The rupture of Achilles tendon is hard to self-healing and repair and it is easily left pain and dysfunction. For a long time, the treatment of Achilles tendon defect by many scholars conducted a lot of research, from the tendon autograft, allograft tendon transplantation to the artificial tendon transplantation, tissue engineering tendon transplantation. Practice has proved that these methods have their own advantages and disadvantages. Although the research and application of scaffold materials for tendon tissue engineering has achieved some success, but the application materials or the presence of biocompatibility, degradation problems or have poor mechanical properties, machining molding defects, there is still a big gap between the ideal scaffold materials. This study evaluated the different biological materials in the repair of Achilles tendon injury in effect, provide a theoretical reference for the key to construct tissue engineered tendon is to find appropriate scaffold materials for tendon cell adhesion, growth and functional differentiation.

Compliance sensation is a unique feature of the human skin that electronic devices could not mimic via compact and thin form-factor devices. Due to the complex nature of the sensing mechanism, up to now, only high-precision or bulky handheld devices have been used to measure compliance of materials. This also prevents the development of electronic skin that is fully capable of mimicking human skin. Here, we developed a thin sensor that consists of a strain sensor coupled to a pressure sensor and is capable of identifying compliance of touched materials. The sensor can be easily integrated into robotic systems due to its small form factor. Results showed that the sensor is capable of classifying compliance of materials with high sensitivity allowing materials with various compliance to be identified. We integrated the sensor to a robotic finger to demonstrate the capability of the sensor for robotics. Further, the arrayed sensor configuration allows a compliance mapping which can enable humanlike sensations to robotic systems when grasping objects composed of multiple materials of varying compliance. These highly tunable sensors enable robotic systems to handle more advanced and complicated tasks such as classifying touched materials.

During the last few years, synthetic self-healing materials have become a new class of emerging smart materials with the ability to repair damage and restore lost or degraded properties or performance using resources inherently available to the system. Success in the design of self-healing materials is important to material safety, product reliability and prolonged lifetime. This article covers fundamental material-independent principles and different self-healing approaches for polymeric materials. Among these approaches, some depend on specific external stimulus to achieve their goal while others regain the physical properties of the pristine material without such external intervention. Both the mechanisms and performance of different methods are discussed and evaluated, along with their advantages and disadvantages. In the end, both the potential application areas and the main challenges are also discussed in this article for a better understanding of future development trend of self-healing polymeric materials.
