This book mainly shows readers how to calibrate and control robots. In this regard, it proposes three control schemes: an error-summation enhanced Newton algorithm for model predictive control; recurrent neural network (RNN) for solving perturbed time-varying underdetermined linear systems; and a new joint-drift-free scheme aided with projected ZNN, which can effectively improve robot control accuracy. Moreover, the book develops four advanced algorithms for robot calibration – Levenberg-Marquarelt with diversified regularizations; improved covariance matrix adaptive evolution strategy; quadratic interpolated beetle antennae search algorithm; and a novel variable step-size Levenberg-Marquardt algorithm – which can effectively enhance robot positioning accuracy. We develop some control and calibration schemes for enhancing the tracking and positioning accuracy of the robot. The first model is a Model Predictive Control (MPC) scheme for robot trajectory tracking, which can optimize tracking error, velocity norm, and acceleration norm. The second model is a new recurrent neural network (RNN), which has better performance in dealing with time-varying underdetermined linear systems with double limits. The third model is a novel Joint Drift Free (JDF) scheme synthesized by the Projection Zeroing Neural Network (PZNN) model, which can effectively solve the motion generation and control of redundant manipulators under disturbance.

The goal of this textbook is to equip readers with as structured knowledge of soft robotics as possible. Seeking to overcome the limitations of conventional robots by making them more flexible, gentle and adaptable, soft robotics has become one of the most active fields over the last decade. Soft robotics is also highly interdisciplinary, bringing together robotics, Computer Science, material science, biology, etc. After the introduction, the content is divided into three parts: Design of Soft Robots; Soft Materials; and Autonomous Soft Robots. Part I addresses soft mechanisms, biological mechanisms, and soft manipulation & locomotion. In Part II, the basics of polymer, biological materials, flexible & stretchable sensors, and soft actuators are discussed from a materials science standpoint. In turn, Part III focuses on modeling & control of continuum bodies, material intelligence, and information processing using soft body dynamics. In addition, the latest research results and cutting-edge research are highlighted throughout the book. Written by a team of researchers from highly diverse fields, the work offers a valuable textbook or technical guide for all students, engineers and researchers who are interested in soft robotics.

Delay insensitive circuits rely on local coordination and control from the ground up, enabling data and signal processing applications without any clock distribution network whatsoever. This ability can bring a welcome relief to projects whose timing infrastructure would otherwise tend to create more problems than it solves. The quest for performant, robust electronics for data and signal processing applications has often depended on the help of a small close-knit faction of specialists in asynchronous circuit design working on the margins of the broader engineering community. On those rare but dreaded occasions when its technical debt comes due, the deeply held assumption of discrete global time in synchronous design (as opposed to asynchronous design) harshly reaffirms the need for their esoteric skills. Sometimes incremental progress is achievable by a combination of synchronous and asynchronous circuitry carefully organized as far as possible to insulate the majority of engineers from unwelcome contingencies. Field Programmable Gate Arrays (FPGA) would seem ideally situated to attract similar interest, but have achieved only limited success in that regard at best. Although undoubtedly due in part to the marketing focus on commercial developers by the major FPGA vendors, this unfortunate circumstance might be more aptly explained by the hard truth that FPGA programming is a little too much like work to fit most people’s idea of a recreational activity.

The electronics industry has grown at a breakneck pace during the past few decades, primarily owing to significant advancements in integration technologies and large-scale systems design - in other words, the introduction of VLSI. Nanodevices have revolutionized the electronics market and human life; they have impacted individual lives to make them more convenient. They are ruling every sector, whether electronics, energy, biomedicine, food, environment, and communication. Low-power VLSI device designs have gotten much attention in recent years, thanks to the growing desire for high-density portable systems with low power consumption. Compact applications demand low power dissipation, and high efficiency in terms of speed is increasing, which in turn brings out new technologies in this domain. Low power consumption must be satisfied in most of these scenarios, and the equally challenging high chip density and throughput goals. As a result, low-power digital integrated circuit design has evolved into a very dynamic and quickly evolving CMOS design sector. Chip density and operation speed increase, resulting in increasingly complex devices with high frequency. The power dissipation of the device, and hence the temperature, increases linearly as the clock frequency of the chip increases. Furthermore, smaller integrated circuits (ICs) with better functions and faster reactions boost the system’s compactness. This book covers the recent nanodevices which include thin film transistors (TFT), tunnel field effects transistors, and carbon nanotubes, as well as new emerging devices such as nanowires, HEM transistors, and their applications.

This contributed book provides a thorough understanding of the basics along with detailed state-of-the-art emerging interconnect technologies for integrated circuit design and flexible electronics. It focuses on the investigation of advanced on-chip interconnects which match the current as well as future technology requirements. The contents focus on different aspects of interconnects such as material, physical characteristics, parasitic extraction, design, structure, modeling, machine learning, and neural network-based models for interconnects, signaling schemes, varying signal integrity performance analysis, variability, reliability aspects, associated electronic design automation tools. The book also explores interconnect technologies for flexible electronic systems. It also highlights the integration of sensors with stretchable interconnects to demonstrate the concept of a stretchable sensing network for wearable and flexible applications. This book is a useful guide for those working in academia and industry to understand the fundamentals and application of interconnect technologies. Interconnects have become essentially important in integrated circuit (IC) and printed-circuit board (PCB) designs. In the present state-of-the-art technologies such as network-on-chip, system-on-chip and 3D staggered integrated circuit designs, interconnects constitute large portion of the entire system. Interconnects dominantly control the signal integrity and are the major source for causing latency, crosstalk and power dissipation in the system.
