Über dieses Buch

This book presents the technological basics and applications of small-scale (mm to sub-mm in length-scales) soft robots and devices, written for researchers in both academia and industry. Author Jaeyoun Kim presents technological motivations, enabling factors, and examples in an inter-linked fashion, making it easy for readers to understand and explore how microscale soft robots are a solution to researchers in search of technological platforms for safe, human-friendly biomedical devices. A compact and timely introduction, this book summarizes not only the enabling factors for soft robots and MEMS devices, but also provides a survey of progress in the field and looks to the future in terms of the material, design, and application aspects this technology demonstrates.

Chapter 1. Introduction
Abstract
Why delve into microscale soft robotics? Why now, of all times? An engineer’s direct answer would be: Because now we can. The need for microscale soft robots and their potential benefits have long been in recognition since the dawn of robotics. In fact, we never stopped making demands for small machines capable of operating in a highly inaccessible, tightly constrained environment, be it an inner organ of the human body undergoing a medical intervention or the gap under the door to a room in a hostage situation. In the former, safety comes first. The robot’s body must be soft enough to avoid causing damages to the surrounding tissues. In the latter, the softness can enable the robot to squeeze its way through narrower door gaps. Clearly, there exist ample reasons for robots to be small and soft.

Chapter 2. Motivations
Abstract
Microscale robots have been around for decades. Soft robots are relatively new to robotics but they have also been on the road to secure their position in the field for at least a decade (Rus and Tolley, Nature 521:467–475, 2015). So, the fusion of the two in recent years, which gave birth to microscale soft robotics, may seem logical and even inevitable (Whitesides, Lab Chip 11:191–193, 2011). In the world of technology, however, a mere co-existence of two related fields doesn’t necessarily guarantee their marriage. There must be compelling reasons, or motivations, for the researchers to invest their time and effort.

Chapter 3. Enabling Technologies
Abstract
The motivations described in the previous chapter have been recognized by researchers in the field of robotics since its early days. Their realization, however, had to wait for a number of key concepts and technological enabling factors to become available. It is interesting to point out that many of these enabling factors have been listed as the targets for future research in soft robotics in the visionary review paper by Trivedi et al. in as early as 2008 (Trivedi et al., Appl. Bionics Biomech. 5:99–117, 2008). In fact, the laborious thrusts to overcome the challenges can be viewed as the process of making the enabling technologies available. This chapter reviews five essential ones among them in detail.

Chapter 4. Soft Robotic Micro-Tentacle: A Case Study
Abstract
Previous chapters have reviewed the motivations towards microscale soft robots, or S 3 robots, and the technological advances leading to their practical realizations. Now the survey of the current progress in the field is in order. It begins with a case study on a representative S 3 robot in this chapter and then introduces top-of-the-line outcomes from the mainstream research efforts in recent years in the following one.

Chapter 5. Current Progress
Abstract
The case study in the previous chapter showed that the motivations and enabling technologies, introduced in the preceding chapters, can function as a good framework for assessing the progress in microscale soft robotics and making predictions on its future. The SRMT, however, represents only one facet of the fast-growing field. There are a number of functional building blocks, both static and dynamic, to be perfected for facile realization of S 3 robots. On the other hand, such building blocks must be integrated properly and creatively to step up the ladder of utilization towards the top rung of standalone, autonomous S 3 robotics.

Chapter 6. Towards Full-Scale Integration and Beyond
Abstract
The previous chapters surveyed the progress made in various sub-fields of microscale soft robotics in recent years. The field is undeniably undergoing rapid changes and expansions, making their survey quite challenging yet exciting. By the time of publication, it is also very probable that the state of the art of the field has already evolved into something very different from a simple sum of the technological building blocks surveyed in the previous chapters. In accordance, this final chapter will review some of the important long-term, essential agendas in microscale soft robotics which will surely stay valid for a longer period of time. Beyond a brief overview, the topics will be discussed by their order in the implementation steps in general, with the materials and fabrication aspects reviewed first and the application of the completed units later.
