Abstract:

Purpose The purpose of this paper is to understand the role of perceived threat, brand congruence, and social support on consumer coping strategies for a preventative health service. Design/methodology/approach An online survey of 570 women aged over 50 in one Australian state was conducted (users and non-users of the service). The data were analyzed using structural equation modeling. Findings A competing models approach reveals that threat on its own is associated with avoidance coping; however, when brand congruence is high, there is an association with active coping. Social support appears to have a buffering effect on threat and is associated positively with active coping and negatively with avoidance coping. Originality/value The study findings suggest that threat appeals should be used with caution in increasing participation in transformative preventative health services due to its double-edged sword effect (increasing both avoidance and active coping). When consumers have social support, this results in active coping and buffers avoidance coping. This research offers useful insights for social marketing and transformative service research.

Abstract:

This paper introduces a project involving a thermoregulation performance experiment design to evaluate the different responses of research subjects to a range of mastectomy bras and external breast prostheses. A set of newly designed heat-reduction mastectomy bras and prostheses were mix-matched with a set of conventional mastectomy bras and prostheses for the experiment. Four combinations of mastectomy bras and external breast prostheses were used: (a) Com A: conventional mastectomy bra and conventional prosthesis; (b) Com B: conventional mastectomy bra and heat-reduction prosthesis; (c) Com C: heat-reduction mastectomy bra and conventional prosthesis; and (d) Com D: heat-reduction mastectomy bra and heat-reduction prosthesis. Nine healthy male subjects (mean age: 31.9 ± 5.9 y and mean under-bust circumference: 35.3 ± 2.8 in) participated in this study in lieu of women who had undergone surgery for double mastectomy and were too self-conscious to expose their scars for sensor attachment. Eight sets of temperature and humidity sensors were placed between the surface of the skin and the prostheses and bra to measure the changes in both temperature and humidity data in a microclimate environment while the participants performed physical activity. The results showed that Com D demonstrated better thermal and moisture control, resulting in lower body temperature and lower humidity increment throughout the entire experiment. The study proved that the heat-reduction mastectomy bra and external breast prosthesis were effective in releasing the trapped heat and perspiration underneath the bra, and thus would provide a positive impact on clothing comfort and wearing experience for women who had undergone mastectomies.

Abstract:

The paper design a double eccentric mass driven spherical robot, the ball is also subject to eccentric force and inertia force that generate by internal drive units in movement. Due to the unique spherical shell, the robot in the dynamic state transition process, Friction cannot offset the robot motion state change due to internal driving motion error of small units. In order to make linear movement of the spherical robot that can smooth start, stop and speed control, the paper design a method for linear motion driven spherical robot with double eccentric mass control. The improved driving eccentric mass of robot total mass ratio is larger, that can provide the eccentric torque and inertia moment more, the robot has higher motion velocity.

Abstract:

The goal of the study is to develop a novel method to manufacture the functional bras. The high precision three-dimensional (3D) scanner was employed to get the point cloud data. A fixed mount was invented to keep the bra cup stable and decrease measuring error. A bottom holder was prepared by the 3D printer to place the bra cup during the injection process. Furthermore, the injection points coordinate values and the injection volumes can be determined based on the 3D image of the bra cup and the thickness of those positions. At last, the three-axis automatic robot which was coupled with a precision liquid dispenser is used to inject the microcapsules solution into the bra cup for the preparation of functional intimate apparel. The proposed method was verified to be feasible and effective through a practical example.

Abstract:

Fishes have evolved different excellent swimming strategies. To study the influence of tail fin swing on the swimming performance of bionic robot fish, with one joint under the same tail swing frequency and amplitude, we designed a novel robot fish, driven by a double-cam mechanism. By designing the profile of the cam in the mechanism, the robot fish can achieve different undulatory motion trajectory of the caudal fin under the same tail swing frequency and amplitude. The mechanism simulated the undulatory motion of crucian carp. We studied the influence of undulatory motion on the swimming speed of robot fish, which was analyzed by dynamic analysis of the undulatory motion and experiments. According to the experimental results, we can find that the swimming speed of the robotic fish is different under various wave motions. When other conditions are the same, the speed that the robot fish can achieve by imitating the swing motion of the real fish is 1.5 times that of the robot fish doing the cycloid motion. The experimental results correspond to the kinetic analysis results. Furthermore, it is proven that the robot fish with a low caudal peduncle stiffness swims faster under a low swinging frequency, and the speed of a robot fish with a high caudal peduncle stiffness is higher under a high tail swinging frequency.

Abstract:

Purpose – The purpose of this paper is to implement a glass-curtain-wall cleaning robot driven by a double flexible rope, so as to replace manual cleaning. The glass-curtain-wall, because of its excellent daylighting performance, damp-proofing characteristics, heat insulation properties and aesthetics, is widely used in modern city buildings. For glass-curtain-wall buildings, regular cleaning of the glass-curtain-wall is necessary to ensure that the surface of the building appears clean and tidy, which in turn contributes toward preserving the overall aesthetic appearance of the city. Currently, the primary method of cleaning glass curtain walls is manual cleaning by workers on a suspended platform. Design/methodology/approach – The mechanical structure of the proposed glass-curtain-wall cleaning robot driven by a double flexible rope is inspired by the way a spider moves by pulling its silk draglines in the air. For self-locking protection and increased rope friction, the robot’s moving section includes a worm reducer and multislot master–slave roller. The cleaning section comprises a water tank, control valve, shower nozzle and brush. The wall adsorbing section is realized by a double rotor. The workspace of the robot is analyzed. Flexible rope winding and unreeling control of the cleaning robot is deduced. The force of the cleaning robot when the double rotor is working is analyzed and calculated. The prototype of the glass-curtain-wall cleaning robot model driven by a double flexible rope is established, and experiments wherein the robot moves along a preset track, as well as cleaning experiments, are performed. Findings – The prototype of the glass-curtain-wall cleaning robot model driven by a double flexible rope can move along the preset track, satisfy the design functions and clean effectively. The experimental results verify the validity and practicality of the robot. Research limitations/implications – The implication of this research is that a glass-curtain-wall cleaning robot model driven by a double flexible rope fulfills the movement strategy and drive-type requirements for cleaning glass curtain walls. The limitation of this research is that it is difficult to implement rapid cleaning. Originality/value – The traditional method of manual cleaning by workers on a suspended platform will be changed after the glass-curtain-wall cleaning robot is manufactured, and the advent of this cleaning robot for the low- and mid-rise buildings will reduce the cost of cleaning buildings, improve the working environment and enhance production efficiency.

Abstract:

This paper presents a doublegyroscope unicycle robot, which is dynamically balanced by sliding mode controller and PD controller based on its dynamics. This double−gyroscope robot uses the precession effect of the double gyro system to achieve its lateral balance. The two gyroscopes are at the same speed and in reverse direction so as to ensure that the precession torque of the gyroscopes does not interfere with the longitudinal direction of the unicycle robot. The lateral controller of the unicycle robot is a sliding mode controller. It not only maintains the balance ability of the unicycle robot, but also improves its robustness. The longitudinal controller of the unicycle robot is a PD controller, and its input variables are pitch angle and pitch angular velocity. In order to track the set speed, the speed of the unicycle robot is brought into the longitudinal controller to facilitate the speed control. The dynamic balance of the designed double gyro unicycle robot is verified by simulation and experiment results. At the same time, the anti−interference ability of the designed controller is verified by interference simulation and experiment.

Abstract:

A passive-walking of a double-legs planar Robot is considered. The dynamic equation of the system walking down a shallow slope, powered only by gravity is established according to Lagrange method. After the equation was transferred to a dimensionless one, it shows the motion is depended not only on the free parameter, the ramp slope γ, but also on the ratio of m/M, m is mass of the foot of the model and M is the mass of the hip as well; The analytic calculations show that at the identical ramp slope γ, the whole moving has different phases: stable period walking and chaos with the increasing of m/M. Its phase portraits and graph of step time interval show the influence to the motion because of the ratio of m/M.

Abstract:

Renishaw Ballbar QC20–W is primarily intended for diagnostics of CNC machine tools, but it is also used in connection with industrial robots. In the case of standard measurement, when the measuring plane is parallel to the robot base, not all robot joints move. The purpose of the experiments of the present article was to verify the hypothesis of the motion of all the robot joints when the desired circular path is placed on an inclined plane. In the first part of the conducted experiments is established hypothesis is confirmed, through positional analysis on a simulation model of the robot. They are then carried out practical measurements being evaluated the influence of individual robot joints to deform the circular path, shown as a polar graph. As a result, it is found that in the case of the robot used, changing the configuration of the robot arm has the greatest effect on changing the shape of the polar graph.

Abstract:

This paper presents a wall-climbing robot which can stably hold and move on the ground-wall surface. The robot uses propeller reverse thrust as an adsorption force and can adapt to the surface of several media materials. The influence of the robot’s structural parameters on its power system is analyzed by comparing a single power system test and a robot prototype power test. A structural analysis of the robot is performed under two specific situations; when he is in transition from the ground to a small slope, and when he is on the slope. The force state of the robot is then obtained in different conditions. Experimental results show that the adjustment range of different rotor inclination angles of the robot, the width of the fixed rotor plate and the different near-ground distances, affect the traction of the robot. The robot motion performance and adaptability under different ground/wall environments are analyzed, by conducting the robot climbing experiment under a small slope, a vertical wooden wall surface and a vertical indoor wall surface. Stable adsorption and optimization tests are also performed. Moreover, the stability of the robot’s motion is verified. Finally, a theoretical and experimental accumulation is laid for the realization of the smooth transition of the robot from the ground to the wall.

Abstract:

Ekphrasis as a question about the right to enchantment The author discusses Fr. Janusz S. Pasierb’s poem spotkanie [meeting] from Zdejmowanie pieczęci [Removing the seal] volume (Warsaw, 1982). He treats the poem as an example of a double ekphrasis – a simultaneous reference to two works of art; one of them is Auguste Ottin’s large sculpture Polyphème surprenant Galatée dans les bras d’Acis (1866) composed into Marie de’ Medici’s fountain in Parisian Jardin du Luxembourg, the other Giovanni Lafranco’s painting Lucina e Norandino sorpresi dall’Orco (c. 1624) from the Borghese Gallery in Rome. The analysis, which evokes mythological, literary (Ariosto, Proust) and iconographical (Redon) contexts, leads to a conclusion about art’s mediating role; about art as ground that allows for enchantment over otherwise inaccessible forms of beauty.

Le but de cette étude était d'identifier un certain nombre de facteurs associés à l'accroissement de la vitesse au pas de un et à la poussée simultanée. Des skieurs d'élite (N = 8) furent sélectionnés à cette fin. Des mesures de fréquence et longueur d'enjambée, de distance parcourue pendant certaines phases, de durée des phases, de même que des mesures angulaires furent obtenues à l'aide de la cinématographie. Pour ces deux techniques, l'accroissement de la vitesse repose presque exclusivement sur la modification de la cadence propulsive. Au pas de un les deux tiers du déplacement surviennent dans la phase de propulsion des bras et du glissement qui s'ensuit. Quant à la double poussée près des trois quarts du déplacement surviennent dans la phase de glissement qui suit la phase propulsive.

We developed a trash-picking service robot with a strong focus on human-robot interaction (HRI) using the double diamond framework. The HRI-focussed hardware features were successfully implemented and tested. The results were shown to satisfy the ease of operation and usability requirements set as development goals for the robot.

Abstract:

Force sensors are used when interaction tasks are carried out by robots in general, and by climbing robots in particular. If the mechanics and electronics systems are contained inside the own robot, the robot becomes portable without external control. Commercial force sensors cannot be used due to limited space and weight. By selecting the links material with appropriate stiffness and placing strain gauges on the structure, the own robot flexibility can be used such as force sensor. Thus, forces applied on the robot tip can be measured without additional external devices. Only gauges and small internal electronic converters are necessary. This paper illustrates the proposed algorithm to achieve these measurements. Additionally, experimental results are presented.

Abstract:

The purpose of this article is to design a new dynamic vibration absorber (DVA) and create a mathematical model to analyze the electrical transmission lines inspection robot movement on the line. First, the vibration of the electrical line while the robot inspector moves along it has been modeled considering the conductor as a stretched string and the robot as a moving load. It follows by using a double pendulum as the dynamic vibration absorber. To better understanding the performance of the DVA, the results are compared with the model in which a robot inspector is considered as a pendulum with a suspension base (here the conductor). This example shows the possibility of usage of the double pendulum as the DVA in electrical transmission inspection robots.

Abstract:

The double hexapod robot consists in two staged hexapod platforms – Stewart Gough platforms - combining in a certain measure the advantages of the robots with parallel kinematics and of the serial robots: high accuracy, high stiffness, fast response and small dimensions, having an extended operating space. Different modelling and construction aspects were described in few previous articles. Some examples of trajectories generated with this positioning system are now presented to illustrate its mobility, as well as the workspaces for one and two hexapods in order to make possible a visual comparison between the two volumes.

Abstract:

Dynamic performance is an important performance of robots used for machine processing. This paper studies the dynamic modeling and evaluation method of a 5-DOF (Degree of Freedom) hybrid robot used in aerospace composite material processing. With the consideration of the dynamics of the serial part, the complete dynamic model of the hybrid robot is established based on the virtual work principle. In addition to the widely considered acceleration term, a dynamic performance evaluation index that comprehensively considers the acceleration term, velocity term and gravity term in the dynamic model is proposed. Using the dynamic performance index, the effect of the placement direction of the robot and the arrangement of the double symmetric limbs on robot dynamics are investigated. The results indicate that the vertical placement is beneficial to the dynamics of the hybrid robot, and the arrangement of double symmetric limbs has different effects on different limbs.

Abstract:

This paper studies the target tracking control strategy of a snake robot and proposes an adaptive sliding mode control method. The strategy ensures the robot follows the target path by controlling the joint angle through feedback, pushing the robot to reach the target position through gait function. In order to achieve target tracking, a kinematic model of a snake robot was first established in this paper. Then, we used double-sine serpentine gait to solve the problem of low steering efficiency caused by regular serpentine gait, and we explored the relationship between control parameters and robot steering. On the basis of gait, in order to further improve the efficiency of target tracking for the snake robot, an adaptive sliding mode control method, based on a new sliding mode reaching law, was proposed. Finally, the effectiveness and practicability of the proposed strategy was demonstrated by comparative analysis and simulation experiments.

Abstract:

The paper deals with the problem of suppressing vibration of the arm of Motoman SSF200 robot within the frame of the technological process. Based on an overview of literature, a semi-active vibration control system was selected and a double ended magnetorheological damper (MR) was designed. After testing the acceleration of the robot arm in milling operation without the MR damper, the device was employed and the acceleration of the robot arm in four operation modes was experimentally tested.The conducted research has proved that the double ended MR damper can be practically applied for suppressing the vibration of the robot arm. The higher power to the electromagnet of the MR damper is exposed, the better vibration suppression is. This means that by changing the strength of current, the technological process of the robot arm is under control. Thus, control over the technological process is simplified when the physical characteristics of the milled material, milled tool or operation vary.

Abstract:

Situé sur un bras de la Seine, au coeur d’un parc de 15ha, entre Rouen et Les Andelys, le moulin d’Andé est à double titre un lieu historique. Si le bâtiment actuel à pans de bois, classé Monument historique, date du XVe siècle, c’est dès 1195 qu’un moulin a été édifié à cet endroit pour approvisionner en farine la garnison du Château-Gaillard. Mais le site est riche également d’une histoire vivante. Depuis plus de soixante ans, Suzanne Lipinska, la propriétaire et l’âme du lieu, accueille artistes et créateurs de toutes disciplines, qui peuvent y travailler à loisir. Les cinéastes, en particulier, ont été et sont nombreux à fréquenter le moulin, réalisateurs venus, à la suite de François Truffaut, préparer voire tourner leurs films, ou talents en herbe reçus en stage pour parfaire leur projet sous la conduite de professionnels.

Abstract:

In response to the problems of high labor intensity, high risk, and poor reliability of artificial live working, a four-wheel-driven spacer bar replacement mobile operation robot has been designed and developed in this paper, and the corresponding kinematic and dynamics model have been established, based on the established double models, the kinematics and dynamics numerical analysis can be realized through INVENTOR and ADAMS, respectively, based on the established kinematics and dynamics models . The results show that the simulation value of the robot joint displacement, velocity, acceleration, and joint force can be able to meet the requirements of kinematic and dynamic constraints during the robot operation. The robot prototype can meet the requirement of dual-split robot working space and the operation joint force control, which not only extend the robot adaptability to the multisplit lines heterogeneous operation environment but also provide an important theoretical technical support for the exploit of the robot physical prototype. Through the robot kinematics and dynamics analysis, the robot mechanical structure parameters and electrical control parameters have been effectively optimized. The weight and cost of the robot have been reduced by 12% and 15% compared to the existed studies. Finally, the robot principle prototype mobile platform has been developed, and the correctness of robot kinematics and dynamics simulation analysis has been verified through the robot principle prototype mobile platform.
