Abstract:
Aim: Intense training of arm movements using robotic devices can help reduce impairments in stroke. Recent evidence indicates that independent training of individual joints of the arm with robots can be as effective as coordinated multi-joint arm training. This makes a case for designing and developing robots made for training individual joints, which can be simpler and more compact than the ones for coordinate multi-joint arm training. The design of such a robot is the aim of the work presented in this paper. Methods: An end-effector robot kinematic design was developed and the optimal robot link lengths were estimated using an optimization procedure. A simple algorithm for automatically detecting human limb parameters is proposed and its performance was evaluated through a simulation study. Results: A six-degrees-of-freedom end-effector robot with three actuated degrees-of-freedom and three non-actuated self-aligning degrees-of-freedom for safe assisted training of the individual joints (shoulder or elbow) of the human arm was conceived. The proposed robot has relaxed constraints on the relative positioning of the human limb with respect to the robot. The optimized link lengths chosen for the robot allow it to cover about 80% of the human limb’s workspace, and possess good overall manipulability. The simple estimation procedure was demonstrated to estimate human limb parameters with low bias and variance. Discussion: The proposed robot with three actuated and three non-actuated degrees-of-freedom has a compact structure suitable for both the left and right arms without any change to its structure. The proposed automatic estimation procedure allows the robot to safely apply forces and impose movements to the human limb, without the need for any manual measurements. Such compact robots have the highest potential for clinical translation

Abstract:
This work focuses on the implementation and design of a six degree of freedom, 6-DOF control of automatic color sorting and pick and place tasks for a robot arm using wireless controlling interface – Blynk apps. Based on the collaboration between the servo motor and input color sensor, this wireless control of automatic color sorting robot arm provides a powerful wireless control GUI (Graphics User Interface) and to enable the method for manual color sorting mode. The color sorting mode is performed once the mode is turned on by the user. The robot arm able to differentiate the colors of the object (input) and categorize or classify the object to the correct places automatically. It provides a stable, efficient, and precision results without any vibration of control as the main target for this project. In this work, six servo motors were used to realize the real robotic arm for industrial use. Five servos were operated to control the entire robot arm motion including the base, shoulder, and elbow as well as one servo is reserved for the positioning of the end effector. Two input variables namely TSC3200 Color Sensors & HC-SR04 Ultrasonic Sensors were employed as the input for the robot arm. The output variable mainly focused on the servo motor as the links for the robot arm to reposition and change the motion for the entire system.

Abstract:
1. The aim of this study was to demonstrate that goal-directed pointing movements, executed at normal speed to a small visual target, but without vision of the movement, do not rely on preprogrammed commands (open-loop process); by contrast these responses are under the control of a feedback loop, which compares the ongoing response and the goal (or its internal representation). When the location of this goal is changed at the onset of the movement, an automatic correction of the path occurs. Modification of the goal was obtained by presenting a target in the peripheral visual field that the subject had to look at and point at as quickly and accurately as possible. When the orienting ocular saccade reached its peak velocity, statistically corresponding to the hand movement onset, the target was suddenly shifted 10 degrees in a random direction. This perturbation was undetected by the subject because of the absence of perception during the saccade. For the compensation to occur, the initial orientation of the movement and also its extent had to be modified. The results revealed 1) a nearly complete compensation of the movement path and a 66- to 80-ms duration lengthening; 2) relatively short reaction times to the perturbations (from 145 to 174 ms, with effective reaction times even 40 ms shorter); 3) nearly identical spatiotemporal movement characteristics to the perturbations, regardless of whether vision of the hand was allowed, suggesting that corrections were subserved by the same mechanisms. 2. The spatiotemporal characteristics of these unconscious corrections were similar to those observed in the classical double-step experiments investigating the intentional modifications of ongoing movements and suggest that they might share some common low-level mechanisms. That is, they could rely on visuokinesthetic feedback loops, which compare the updated information provided by the eye at the end of the saccade and the proprioceptive information of the end point effector (the fingertip here); they could also rely on feed-forward processes detecting the discrepancy between an efference copy of the movement and the new goal; or they could rely on a combination of those two main processes.

Abstract:
Robot tools, or in more general terms, end‐of‐arm tools, or robot end‐effectors are general purpose, programmable or task‐oriented devices connected between the robot wrist and the object or load to be manipulated and/or processed by the robot. They can offer and/or limit the versatility of grasping and/or processing of different components, sensing their characteristics and working together with the robot control system to provide a reliable “service” throughout the component manipulation cycle. Reconfigurable robot tooling enables the robot to rapidly change its end‐effectors or fingers of its end‐effectors, typically under programmable software control. The importance of providing lean‐flexibility by means of reconfigurable, automated robot hand changers (ARHC), particularly in small‐batch robotic welding, assembly, machine loading and in other flexible robot cells, is discussed with examples. Some known systems are demonstrated and the “Ranky‐type” ARHC design is illustrated in more detail.

Abstract:
This introduction offers a brief account of Ovshinsky’s career. It outlines his development from machinist and toolmaker to independent inventor and notes how his work on automation, including his study of cybernetics and neurophysiology, led to his most important discovery of the “Ovshinsky effect,” using amorphous thin films. This switching effect was used to create semiconductor devices like his threshold switch and phase-change memory. After sketching Ovshinsky’s later career as the director of his own research and development laboratory, ECD, the introduction considers the source of Ovshinsky’s scientific and technological creativity in the thought processes of his self-educated, intuitive mind, which relied heavily on the use of analogies and visualization. It concludes by briefly considering how Ovshinsky’s work is related to his social-historical context, in particular, how his inventive career spans the transition from the industrial to the information age, making distinctive contributions to both.

Abstract:
Since the inception of the European integration process, the Franco-German axis is considered to be a major driving force. Even today, Europe moves faster in the presence of an entente between France and Germany. However, the harmonization of German and French positions is not quasi-automatic as it used to be. The desynchronization that occurred over time is based on various factors such as the German unification, the EU's enlargements, and the change in German self-perception. One of the contexts in which the divergences between Paris and Berlin can be seen is related to the Euro zone rescue operations. Germany came to the fore in the resolution process and made clear her preferences, which are not always truly supported by France. The drifting-apart that started after the end of the Cold War thus continues.

Abstract:
Sometime between 1936 and 1946, there was a change in etymology, at least in the English language. The word computer came to mean the machine not the man. Old habits, of course, die hard. And so, such terms as automatic calculating machines and computing machines remained in common use, along with the cautious adoption of computer, until the end of the 1940s. But at the beginning of that war-ravaged, bomb-splattered decade, George Stibitz (1904–1995), a mathematical physicist working for Bell Telephone Laboratories in New Jersey, wrote a memorandum on a machine he and his colleague Samuel B. Williams had built in which computer unequivocally meant a machine. Indeed, they named their creation the Complex Computer because it was designed to perform arithmetic operations on complex numbers—computations necessary in the design of telephone networks, which was Bell’s forte. There was, of course, much more happening in the realm of computing than a change in the meaning of a word. Computers were actually being built, increasingly more complex, more ambitious in scope, more powerful, faster, and physically larger than the punched-card machines that largely dominated automatic calculation. They were being built in at least three countries: America, Germany, and England. These machines, developed in different centers of research, formed evolutionary families, in the sense that machine X built at a particular center gave rise to machine X + 1 as its successor. The word “evolution” carries with it much baggage. Here, I am speaking not of biological evolution by natural selection à la Darwin, but cultural evolution. The latter differs from the former in a fundamental way: biological evolution is not driven by goal or purpose; cultural evolution is always goal driven. In the realm of computers—artifacts, therefore part of culture—for example, a goal is established by the designers/engineers or potential client, and a machine is built that (one hopes) satisfies the goal. If it does satisfy the goal, then well and good (at least for a time); otherwise, a new effort will be initiated that strives to correct the flaws and errors of the earlier machine.

Abstract:
At the end of the twentieth century there were major reforms to the honours system. These were connected to larger processes of social change following the political and social shifts of the 1980s and 1990s. In 1993 the honours system was revised by John Major and civil servants concerned about its reputation as class-based and automatic for civil servants. The lower ranks of the Order of the British Empire (which make up a majority of total honours given out) were reoriented towards voluntary service and away from professional state service. Honours became a way of paying volunteers to do work once done by the state using social capital rather than money. This chapter also details the relationship between these changes and the role of the monarchy in British society. After 1948, all British recipients of honours at the level of MBE and above were entitled to visit Buckingham Palace and receive their award from a royal personage. Autobiographical writing suggests a set of characteristic experiences and feelings. Many who recorded their experiences not only celebrated their encounter, but also expressed empathy with the monarch, affirming both the normalcy of the royal family and also their special status. John Major’s reforms (and similar ones that followed them in the early 2000s) thus reintegrated two functions of the monarchy—its role as the affirmer of national merit through the honours system and its status as the leader of the voluntary sector in Britain.

Abstract:
The development of a remotely operated, Co-Robotic Positioning Device (CRPD) for instrumental backing and optimal base position to robotic arms in tele-surgery is discussed. To optimise the setting of robotic operating rooms (ROR) by reducing the structures’ size around the patient and by selecting task-driven layouts, the design of a hanging servo-carrier coming from the ceiling is chosen, rather than a device located on the floor. The present study prospects a split-duty approach, distinguishing the Co-Robotic Positioning Device, CRPD, from the front-end effectors, each subsystem hierarchically controlled by remote location, in keeping with optimal protocols. The attention is focused on the slave-carrier, to establish an optimal design of the CRPD, based on the characteristics of robotic effectors and the surgical task. The CRPD is conceived to support (up to four) robotic effectors, each one equipped with proper tools (endoscope, scalpels, scissors, suture needles, etc.). The CRPD, actually, by optimally positioning the robotic arms, avoids the need of manual deployment, in current setups often necessary to avoid singularities or collisions. The Automatic Changing Device for Surgical Tools, ACD-ST, is another significant device of the conceived slave-carrier. It allows the tele-operating surgeon to change the tools (scalpels, scissors, etc.) by a direct command from his console. Example applications aim at ticklish endoscopic/tomic operations that require high accuracy with low involved forces such as cardio-thoracic-surgery, abdominal surgery, spine-surgery, microsurgery (neurosurgery, hand-surgery, ophthalmic-surgery, ear-nose-throat surgery), say, the typical domains of MIRS, where robotic surgery is quickly expanding.

Abstract:
This paper seeks to identify a pattern of air turbulence that reflects the effect of buildings on air turbulence characteristics measured in open spaces in Western São Paulo State, Brazil. Atmospheric turbulence was estimated using high-frequency observations of the three orthogonal wind components (u, v, w). A CSAT3 sonic anemometer from Campbell Scientific Inc. (CSI) was deployed on the roof of a building, and the turbulent components (u', v', w') were systematically measured and recorded at 0.1 s and 5 min intervals, respectively, over 100 days between the end of summer (March 2015) and beginning of winter (July 2015) with a CR3000 automatic data acquisition system (CSI). The data analysis took into account the diurnal and nocturnal variability of the turbulence, and the experimental results revealed the existence of a daily vertical circulation pattern. The w component varied between 15 and 45 cm.s-1 on average, and the turbulent fluctuations observed indicated that an ascending component with a speed of up to 1 m.s-1 predominated during the middle of the day and early afternoon. Throughout the night until the early hours of the morning, a less robust, subsiding component with a speed of up to 0.5 m.s-1 was observed. The mean horizontal flow (u, v) was low-speed (around 1 m.s-1) and predominantly from the southeast. There was a consistent change in the direction of this wind, which changed to easterly during the morning as the ascending branch developed. We propose a model for air circulation close to the surface in which this change in direction of the wind is the main effect of the building on the observed turbulence.

Abstract:
Most fixed automations in traditional manufacturing systems are not equipped to manage product variations efficiently. This paper presents a design and configuration for a machine-vision-equipped robotic packing cell that is capable of managing a wide range of product sizes. Product size information is gathered at an earlier stage in the manufacturing process and then transferred electronically to the robot cell. Different controllers are needed to manage robot cell functions related to incoming product, machine vision, robot control, robot manipulator, and multiple layers of safety control information. Each controller, due to the nature of its function, has different advantages in processing different data types. In order to achieve the highest possible robot manipulator utilization rate, the assignment of information processing among controllers needs to be thoughtfully planned, especially for the critical mathematical routines. Coordination and calibration between charged-coupled device (CCD) cameras and robots in existing manufacturing facilities are configured with considerations for building vibrations, lighting conditions, and signal processing assignments among the available devices. System efficiency is improved when the vision signal, robot logical signal, and robot manipulator signal processing units are running cohesively in parallel. The capability of the machine-vision-assisted robot end effector automatic path adjustment, to pick up and pack different sizes of products dynamically, allows a higher level of flexibility and efficiency. This paper describes a feasible design and configuration for an integrated machine vision robotic cell in a manufacturing system.

This study attempts to answer the question of how a narrow (9-ft) lane dedicated to Automated Vehicles (AVs) would affect the behavior of drivers in the adjacent lane to the right. To this end, a custom driving simulator environment was designed mimicking the Interstate 15 smart corridor in San Diego. A group of participants was assigned to drive next to the simulated 9-ft narrow lane while a control group was assigned to drive next to a regular 12-ft AV lane. Driver behavior was analyzed by measuring the mean lane position, mean speed, and mental effort (self-reported/subjective measure). In addition to AV lane width, the experimental design took into consideration AV headway, gender, and right lane traffic to investigate possible interaction effects. The results showed no significant differences in the speed and mental effort of drivers while indicating significant differences in lane positioning. Although the overall effect of AV lane width was not significant, there were some significant interaction effects between lane width and other factors (i.e., driver gender and presence of traffic on the next regular lane to the right). Across all the significant interactions, there was no case in which those factors stayed constant while AV lane width changed between the groups, indicating that the significant difference stemmed from the other factors rather than the lane width. However, the trend observed was that drivers driving next to the 12-ft lane had better lane centering compared to the 9ft lane. The analysis also showed that while in general female drivers tended to drive further away from the 9-ft lane and performed worse in terms of lane centering, they performed better than male drivers when right-lane traffic was present. This study contributes to understanding the behavioral impacts of infrastructure adaptation to AVs on non-AV drivers.
