Self-Localization plays an important role in the mobile robot autonomous navigation. The Wheel Mobile robot usually contains a large number of different sensors, such as odometry, gyro, laser, camera and so on. All these sensors provide the information of robot localization and all these information should be considered for the optimal location. However, for the cost of the iRobot, we could not be equipped with a lot of sensors. We have only encoder sensor and gyro sensor. So this paper researches mobile robot localization only using odometer and gyro sensor based on Extended Kalman Filter (EKF). The method is that the iRobot fuses the messages from encoder sensor and gyro sensor by EKF theory, which can collect the errors that obtained the robot's orientation and position. The experiment results appear that the proposed self-localization method is effective and feasible.
自定位在移动机器人自主导航中起着重要的作用。Wheel Mobile机器人通常包含大量不同的传感器,如里程计、陀螺仪、激光、摄像头等。所有这些传感器都提供了机器人的定位信息,这些信息都是最优定位需要考虑的因素。但是,由于iRobot的成本,我们无法配备很多传感器。我们只有编码器传感器和陀螺传感器。为此,本文研究了基于扩展卡尔曼滤波(EKF)的仅使用里程计和陀螺传感器的移动机器人定位。该方法是利用EKF理论将编码器传感器和陀螺仪传感器的信息进行融合,收集得到机器人的姿态和位置的误差。实验结果表明,所提出的自定位方法是有效可行的。

With the growth of aging populations in both developed and developing countries and the increase of noncommunicable disease, the contradiction between increasing healthcare demands and the shortage of medical specialists have become more and more serious. Wearable personal health devices (PHDs) provide a good solution to this problem. But due to the proprietary interface and data protocol, the compatibility and extensibility problem among different PHDs producers strongly influenced the spread adoption of the wearable PHDs in the field of telemedicine. So we designed and implemented a ubiquitous health monitoring system based on Android tablet, which can not only acquire and process the physiological signals from non-standard laboratory developed multi-function wearable health monitoring sensors, but also acquire and process the physiological signals from standard PHDs comply with Continua Alliance or/and ISO/IEEE 11073 standards. The preliminary results demonstrate that this system can not only receive data from standard and non-standard PHDs, but also do the arrhythmia classification and heart rate variability analysis in real time.
随着发达国家和发展中国家人口老龄化的加剧和非传染性疾病的增加,不断增长的医疗需求与医疗专家短缺之间的矛盾越来越严重。可穿戴个人健康设备(PHDs)为这一问题提供了一个很好的解决方案。但由于专用接口和数据协议,不同博士之间的兼容性和可扩展性问题严重影响了可穿戴博士在远程医疗领域的广泛采用。因此,我们设计并实现了一种基于Android平板电脑的无所不在的健康监测系统,该系统既可以采集和处理非标准实验室开发的多功能可穿戴式健康监测传感器的生理信号,也可以采集和处理符合Continua Alliance或/和ISO/IEEE 11073标准的标准博士的生理信号。初步结果表明,该系统不仅可以接收标准和非标准博士的数据,还可以实时进行心律失常分类和心率变异性分析。

In this paper, we present a novel authentication method based on image feature matching to make intelligent lock key can be defined by user which will improve the security and ease-use of intelligent electronic lock. It is a new unlock scheme for intelligent lock that may replaces the text passwords and biological features which are typically used in intelligent lock system. In this method, an object or a digital picture displayed on a physical user-owned device such as a mobile phone can be defined as the intelligent electronic lock key. Firstly, obtain the image of object or digital picture that user defines as the key and the image of the user used for unlocking respectively. Secondly, highly distinctive optical features are extracted from two images and then matching with the features, afterwards the distance between two image's keypoints constitute a discriminant vector. Finally, a LINEAR Support Vector Machine (SVM) is used to classify the discriminant vector. Simulation and experimental results demonstrate the feasibility of proposed approach. The experimental results have obtained satisfactory effect.

The grinding process is influenced by many factors which make it prone to fluctuations in the quality and hard to guarantee the effectiveness and reliability. Therefore, as for this problem, an adaptive adjustment model of the parameters in grinding process is established. First single factor experiments were conducted to get the influence of the processing parameters on the quality qualitatively and the variation range of the parameters can also be obtained. Then, based on the orthogonal experiments, multiple linear regression method was used to establish the empirical relationship between the processing parameters and product quality quantificationally. Moreover, the parameter sensitivity function was presented through the relationship. On the basis of the analyses above, the model of the adaptive adjustment of the parameters was presented using fuzzy theory and the adjustive sequence, direction and step length were given. Finally experiments were conducted and the results show the effectiveness of the adjustment method.

With the development of artificial intelligence, robot navigation based on natural language processing is concerned by more researchs. At the present stage, there are few studies on route natural language processing (RNLP), and there is no professional corpus, so the method of route natural language processing is generally based on a small amount of restricted corpus. This paper puts forward a method of semantic extraction based on semantic role labeling. Firstly, the simulation environment is built, and the route natural language corpus is built. Then, based on the analysis of the route natural language corpus, this paper proposes several common chunks of route natural language, and carries out the chunking experiment. Finally, semantic role labeling (SRL) is performed on the basis of the chunking. According to the results of semantic role labeling, navigation intention map is generated. The experimental results show that this method is suitable for the semantic extraction of route natural languages with non restricted.
随着人工智能的发展,基于自然语言处理的机器人导航受到越来越多的研究关注。在现阶段,关于路由自然语言处理(RNLP)的研究很少,也没有专业的语料库,因此路由自然语言处理的方法一般是基于少量的受限语料库。提出了一种基于语义角色标注的语义抽取方法。首先,构建仿真环境,构建路由自然语言语料库。然后,在对路线自然语言语料库进行分析的基础上,提出了几种常见的路线自然语言块,并进行了分块实验。最后,在分块的基础上进行语义角色标注(SRL)。根据语义角色标注结果,生成导航意图图。实验结果表明,该方法适用于无约束的路线自然语言的语义提取。

This paper the adaptive backstepping control algorithm (ABCA) is proposed for dual-arm cooperative manipulators to achieve a precise trajectory tracking in the task space. Firstly the Lagrange function is employed to construct the dynamic mode of the upper part of the humanoid, the modified dynamic mode is obtained through decoupling the each joint. Secondly the modified dynamic is lower computation burden and extends the application the dual-arm manipulators. Moreover the backstepping control algorithm is designed to implement the dual-arm cooperative control. Finally the effectiveness of the proposed control approach and theoretical discussion are proved by the experiences compared with the robust control method (RCM), which show the proposed algorithm could asymptotically converge to zero to show the validity of the simulation results.

Personalization recommendation can effectively solve the negative influence of information overload to users in the environment of big data. And the existing personalization recommendation model is insufficient in integrating the time characteristics of users' behavior. We build a new extend model of personalization recommendation based on the method of latent factor model. Time characteristics of users' historical behavior are introduced into new model to improve the predictions' accuracy. we implement the new model based on the method of factorization machines, and verify the validity of new model by using the data of movielens dataset. Experimental results demonstrate better performance of new model in improving the predictions' accuracy of users' preferences compared with existing model.

Pub Date : 2016-08-01 DOI: 10.1109/ICINFA.2016.7831916
A. Hajiloo, W. Xie, Zhijun Fu
In the standard MPC formulations, there is a single objective function which is normally the summation of weighted quadratic functions. Although several control specification can be considered in the single objective function, choosing the appropriate weighting factor associated with each cost function poses challenge to the control designers. This work proposes a novel MPC scheme based on multi-objective optimization. At each sampling time, the MPC control action is chosen among a set of optimal solutions based on the Nash bargaining solution. The stability and controller design are projected as LMIs. It is shown through the examples that the proposed method can provide better control performance compared with the other methods in the literature of control systems.

Nowadays, the minimally invasive virtual vascular surgery system is of particular interest. To provide realistic surgical training, collision detection plays an integral role in virtual vascular surgery. However, the blood vessel such as abdominal aorta has the characteristics of plasticity, viscoelasticity, anisotropy, inhomogeneity, and nonlinearity, which lead to complex deformation models and large-scale calculations in the collision detection process. To solve this problem, a finite-element-method based on deformation model for the abdominal aorta was provided. Then a hybrid bounding volume collision detection method, AABB-K-DOPs, was proposed to speed up the organ deformation reaction. Experimental results show that, compared with traditional methods, the proposed method accelerates real-time collision detection without affecting the accuracy.
目前,微创虚拟血管手术系统备受关注。为了提供真实的手术训练,碰撞检测在虚拟血管手术中起着不可或缺的作用。然而,腹主动脉等血管具有可塑性、粘弹性、各向异性、非均匀性和非线性等特点,导致碰撞检测过程中的变形模型复杂,计算量大。针对这一问题,提出了一种基于腹主动脉变形模型的有限元分析方法。然后提出了一种混合边界体碰撞检测方法AABB-K-DOPs,以加速器官变形反应。实验结果表明,与传统方法相比,该方法在不影响检测精度的前提下,提高了碰撞检测的实时性。

Future robot applications will require cloud computing. Using an architecture of cloud robotics would increase performance over hardware constraints (e.g., processors, memory, and power). In this paper, we propose a control middleware for cloud robotics, which not only can receive the robots' requests and allocate the cloud resources based on the robots demand, but also can ensure the connection between the robots and the cloud more stability. And then, we use an autonomous, humanoid robot to test the first stage of the control middleware. Effectiveness of this control middleware is demonstrated by experiments.
未来的机器人应用将需要云计算。使用云机器人架构将提高硬件限制(例如,处理器、内存和电源)的性能。本文提出了一种用于云机器人的控制中间件,它不仅可以接收机器人的请求并根据机器人的需求分配云资源,而且可以保证机器人与云之间的连接更加稳定。然后,我们使用一个自主的人形机器人来测试控制中间件的第一阶段。实验证明了该控制中间件的有效性。
