Underactuated Robot

Underactuated robotics is an emerging research direction in the field of robotics. The control input of the underactuated robot is less than the degree of freedom of the system. It has the advantages of lightweight, low energy consumption, excellent performance, and broad development prospects. This article reviews the state of the art on underactuated robotics. On the basis of previous studies, this article takes the non-holonomic constraint equation as the entry point to classify and summarize underactuated robot and their common mechanisms. The controllability of underactuated robot is further discussed. The control flow of underactuated robot is described based on the open–closed control method. In the closed-loop control, the control method based on the fuzzy system is mainly used. Finally, the difficulties in the current research of underactuated robot are summarized, and the future research directions are prospected.

This conceptual paper concerns information processing, and focuses on the methods and mechanisms used by marketers and academics in attempting to explore mental processes, particularly regarding perception and cognitive mapping in relation to marketing communications. The paper reviews the extensive literature in this domain, deriving information and models from a wide variety of disciplines including: cognitive information processing, attitudes and attitudinal change, elaboration and receiver involvement, sub-routines and sub-processors, semiotics, cognitive science and psycholinguistics. We conclude by suggesting that each of these disciplines has a role to play in terms of future research direction, and that the field of information processing still provides a rich and fertile basis for significant developments to take place.

A useful and increasingly common additive manufacturing (AM) process is the selective laser melting (SLM) or direct metal laser sintering (DMLS) process. SLM/DMLS can produce full-density metal parts from difficult materials, but it tends to suffer from severe residual stresses introduced during processing. This limits the usefulness and applicability of the process, particularly in the fabrication of parts with delicate overhanging and protruding features. The purpose of this study was to examine the current insight and progress made toward understanding and eliminating the problem in overhanging and protruding structures. To accomplish this, a survey of literature was undertaken, focusing on process modeling (general, heat transfer, stress and distortion, and material models), direct process control (input and environmental control, hardware-in-the-loop monitoring, parameter optimization, and post-processing), experiment development (methods for evaluation, optical and mechanical process monitoring, imaging, and design-of-experiments), support structure optimization, and overhang feature design; approximately 140 published works were examined. The major findings of this study were that a small minority of the literature on SLM/DMLS deals explicitly with the overhanging stress problem, but some fundamental work has been done on the problem. Implications, needs, and potential future research directions are discussed in-depth in light of the present review.

Purpose – Reshoring and insourcing decisions have been discussed in the popular press, yet coverage of these topics in the academic literature is limited. The purpose of this paper is twofold: first, it seeks to develop a more complete understanding of the underlying drivers of reshoring and insourcing decisions and their permutations. Second, it seeks to provide directions for future research to further analyze the link between drivers and outcomes of the reshoring and insourcing phenomena. Design/methodology/approach – This research follows a conceptual approach guided by transaction cost economics (TCE) and organizational buying behavior (OBB) theories. First, a theoretical framework of reshoring and insourcing decisions is developed. Next a comprehensive summary of reshoring and insourcing drivers is evaluated, yielding an in-depth discussion of future research directions (FRDs). Findings – The analysis demonstrates that the framework can be utilized to explain recent insourcing and reshoring changes of firms and to help dismantle the external and organizational challenges associated with reshoring and insourcing decision making. Research limitations/implications – Three FRDs are presented in the light of TCE and OBB. A fourth research direction highlights additional contextual factors outside the scope of these two theoretical lenses. These four research directions yield insightful implications for scholars and contribute to the emerging reshoring and insourcing literature. Practical implications – The full array of potential reshoring and insourcing permutations are structured to allow for an elaboration of their respective drivers. Moreover, enablers and obstacles in implementing the multitude of combined reshoring and insourcing decisions are highlighted and summarized as contextual variables. Originality/value – The concluding conceptual framework guides the evaluation of the reshoring and insourcing driver-outcome relationship across various value creation tasks and provides guidance to scholars and managers alike.

AbstractArguably, automation is fast transforming many enterprise business processes, transforming operational jobs into monitoring tasks. Consequently, the ability to sustain attention during extended periods of monitoring is becoming a critical skill. This manuscript presents a Brain-Computer Interface (BCI) prototype which seeks to combat decrements in sustained attention during monitoring tasks within an enterprise system. A brain-computer interface is a system which uses physiological signals output by the user as an input. The goal is to better understand human responses while performing tasks involving decision and monitoring cycles, finding ways to improve performance and decrease on-task error. Decision readiness and the ability to synthesize complex and abundant information in a brief period during critical events has never been more important. Closed-loop control and motivational control theory were synthesized to provide the basis from which a framework for a prototype was developed to demonstrate the feasibility and value of a BCI in critical enterprise activities. In this pilot study, the BCI was implemented and evaluated through laboratory experimentation using an ecologically valid task. The results show that the technological artifact allowed users to regulate sustained attention positively while performing the task. Levels of sustained attention were shown to be higher in the conditions assisted by the BCI. Furthermore, this increased cognitive response seems to be related to increased on-task action and a small reduction in on-task errors. The research concludes with a discussion of the future research directions and their application in the enterprise.
