Cable-driven parallel robots (CDPRs) are widely used in precision industries owing to more advantages such as large work-space, lightweight, and high velocity. A CDPR is actuated by polymer cables connected to an end-effector. However, the polymer cables for CDPRs have complex non-linear characteristics including structural elongation, hysteresis, and dynamic creep. These characteristics of the cables cause the non-linearly change of cable length, which makes the position error of the end-effector. In this research, we propose a nonlinear dynamic model based on the viscoelastic cable dynamic model to describe dynamic creep behaviors. The dynamic model is easily integrated with a scheme position control to increase the accuracy by compensating errors by cable elongation.

Because of the requirements of automated processing, the cutting status of a tool should be monitored in real-time to find out the processing quality in advance and detect cutting abnormalities in time. Thus, we developed an application called APP for tool-life management and damage detection to help operators control the timing of tool replacement and avoid time-delays and loss after damage to the product. The proposed system consists of two sub-systems: an electronic system (to capture signals) and a software system (APP). The electronic system has an accelerometer, a signal capture card, a current sensor, and a temperature sensor. The software system has operating interfaces, data visualization, and early warning systems. The principal component analysis uses a linear combination with the largest variance. The eigenvalues and eigenvectors can be obtained by drawing a slope diagram of the number of principal components by eigenvalues. The point when the slope changes significantly can be used as the selected monitoring characteristic parameter. To reduce the manpower required for follow-up processing, the proposed system can be combined with different controllers to achieve customized parameter adjustment. Unmanned control can ensure processing efficiency and quality.

Knee Osteoarthritis is a common disease in middle-aged and elderly people. We develop an entertainment-education Unity3D game connected to an electric puller with moisture absorption and scraping function which promotes knee maintenance. The fun of the game encourages users to learn more about the knowledge of knee-joint maintenance. We investigate a group of middle-aged and elderly people for over 2 months during which the activities of knee-joint maintenance were integrated into the four modes of the game: massage, cave-finger pressure, slapping, and cupping therapy. The empirical research together with Logistic Regression analysis shows that the effects of all of the four game-modes are statistically significant. In particular, 64.91% of the participants reduced their knee pain. This proves that the game of knee maintenance relieves the pain. A further upgrade of the fun and entertainment of our games is expected to receive attention from more users and consequently to benefit many more patients.

Nowadays, robots have been applied to a variety of applications and industries. The rapid growth promotes the development of various robots for our life. For example, the huge labor work may be replaced with a robot in the catering industry. During the process, we observe if some routine jobs can be performed by a robot instead of people, then the performance can be improved and the cost can be saved. Especially, the meal delivery is a typical example that can be replaced by a robot. As a result, we address this issue by designing and implementing a meal delivery system. In contrast to existing meal delivery systems, our system allows consumers to take their own meals without waiters. In order to make our system user friendly, AGV (Automatic Guided Vehicle) and a robotic arm assembled by us are integrated to develop this system.In order to achieve the goal mentioned above, we aim at proposing a novel approach for the proposed system for the following stages. First, we try to construct a map of an environment for a robot because most food environments are indoors. Furthermore, we construct scenes for surrounding objects with laser sensors. Second, this map is applied to indoor navigation along the shortest path computed by the global planning. Third, the regional planning is applied to plan paths to avoid obstacles. Finally, we present a method to let a robot put a meal on the table by detecting its height first. In order to perform this action, we use an icon of the edge of a table.The proposed work can really provide a service while delivering a meal in a restaurant. Customers in a restaurant are unnecessary to taking a meal by themselves to replace waiters. As a result,, the sharing of labor saving time is achieved. The experiment shows that our work is really suitable for catering applications.

With the popularization of Near Field Communication (NFC), many mobile phones have built-in NFC functions, such as tag quick access, data transmission, identification, and micropayment, which makes personal health record (PHR) person-centered. It provides personal health-related information, customized preventive health information, and practices the concept of preventive care. However, due to the inconvenience of data input and concern of personal data leakage, the penetration rate of PHR has not been effectively increased. This paper uses NFC to provide PHR conveniently with a real-time input and authorization mechanism such as NFC tag writing, NFC tag input, quick start of NFC tag authorization, and a mobile phone NFC peer-to-peer authorization. Through the usage of NFC, the issue of inconvenient data input and data leakage of PHR can be solved. The result helps increase the utilization of PHR to practice the preventive care concept.
随着近场通信(NFC)技术的普及，很多手机都内置了标签快速存取、数据传输、身份识别、微支付等NFC功能，使得个人健康记录(personal health record, PHR)以人为本。它提供个人健康相关信息，定制预防健康信息，并实践预防保健的概念。然而，由于数据输入的不便和个人数据泄露的担忧，PHR的普及率并没有得到有效的提高。本文利用NFC为PHR提供了方便的实时输入和授权机制，如NFC标签写入、NFC标签输入、NFC标签授权快速启动、手机NFC点对点授权等。通过使用NFC技术，可以解决PHR数据输入不方便和数据泄露的问题。结果有助于提高初级医师的使用率，实践预防保健理念。

Parkinson’s disease (PD) has an average onset age of 55 years old. Its incidence increases with age. Due to an aging demographic, PD poses an increasing burden on patients and health care resources. PD causes tremors, rigidity, abnormal gait, postural instability, and freezing of gait. These symptoms diminish patients’ quality of life. Continuous rehabilitation of PD patients is more effective in the long term than either pharmacotherapy or surgical treatment. Nevertheless, a patient's motivation for rehabilitation suffers from the difficulties associated with the need for frequent visits to a rehabilitation center. The purpose of this study is to develop a serious game based on augmented reality for the rehabilitation of patients with PD. The game was designed to allow patients with PD to ambulate while following virtual visual cues in a real environment as well as incorporated levels with increasing difficulty. We assess improvements in gait and a sense of balance after 3 weeks of training. The results show that all patients have had improvements in these two outcomes. The results of this study provide references for future study and develop more or methods of playing rehabilitation games.

To study the impaired cerebral autoregulation mechanism of postural orthostatic tachycardia syndrome (POTS) patients under carbon dioxide, a nonlinear regression model was applied to evaluate their cerebrovascular responses to carbon dioxide (CO2). The cerebral blood flow (CBFV), end-tidal carbon dioxide (${{text{P}}_{{text{ETC}}{{text{O}}_2}}}$), and other cardiopulmonary signals were processed for each subject with a tilt table experiment and hyperventilation. The sigmoidal model for cerebrovascular responses to CO2 during the hyperventilation phase for POTS patients demonstrated an observable dissimilarity in comparison with control groups of healthy elders and healthy youths, especially in its range of change in CBFV.

The visually impaired are exposed to many dangers while walking because of the lack of information on the various obstacles. In this paper, we proposed an obstacle recognition system that provides voice guidance in real-time for the visually impaired. The system informs on obstacles and finds locations of the obstacles such as traffic lights, bollards, and braille blocks. We developed an obstacle recognition system using Raspberry Pi and evaluated its performance by applying the system to a programmable remote control car. The performance evaluation proves that the system successfully avoids the obstacles and guide safely.

The flexible resources of Active Distribution Networks (ADNs) is essential to increase both ADN's local flexibility but also flexibility capacities of the regional power system. More flexibility will help integration of large populations of Distributed Energy Resources (DER). In order to evaluate and improve the performance of investments on flexible resources, an assessment to the resource deployments and operation performances of ADN should be designed and executed. To step further, if this assessment can be executed persistently and continuously, it will help operators make operation decision. This article proposes a flexibility assessment scheme to monitor the effectiveness and functioning of the deployed ADN flexible resources. The scheme includes developing Digital Twin (DT) applications representing ADN. For simulation, real-world operating data are pumped from the physical distribution network (DN) to the DT applications. Performance indices of the status quo flexible resources are computed within our DT flexibility assessment framework. The main contribution of the proposed framework is to improve ADN flexibility planning and build a closed loop system including ADN planning, enactment, and operation. Further studies will focus on the typical scenario generations of Digital Twin.

In the manufacturing industries, computer vision techniques play an important role in predicting the surface roughness of the workpiece in turning operations. The regression method has become more popular in the implementation of deep learning as it is the most basic application and. In this study, a regression with Keras deep neural network model is used to accurately evaluate the correlation between surface image characteristics and actual surface roughness using the machining parameters and the gray level of the surface image. The obtained results showed that the Keras Deep Neural Network model with a training data set of 57 values has an average accuracy of 80.52 % for predicting surface roughness in turning operations.
