We consider the problem of selecting a subset of p out of n sensors for the purpose of event detection,in a wireless sensor network（WSN）.Occurrence of the event of interest is modeled as a binary Gaussian hypothesis *** this case sensor selection consists of finding,among all（~n） combinations,the one maximizing the Kullback-Leibler（KL） distance between the induced p-dimensional distributions under the two *** exhaustive search is impractical if n and p are large,as the resulting optimization problem is *** propose a suboptimal approach with computational complexity of order■（np）.This consists of relaxing the 0/1 constraint on the entries of the selection matrices to let the optimization problem search over the set of Stiefel *** finding the Stiefel matrix is a nonconvex problem,we provide an algorithm that is guaranteed to produce a global optimum for p = 1,through a series of judicious problem *** case p > 1 is tackled by an incremental,greedy *** obtained Stiefel matrix is then used to determine the sensor selection matrix which best approximates its range *** simulations are used to assess near optimality of the proposed *** also show how the proposed approach performs better than exhaustive searches once an upper bound on the computation time is set.

Accelerometer-based control of an industrial robotic arm

Accelerometer-based control of an industrial robotic arm

IEEE International Workshop on Robot and Human Communication (ROMAN)

作者： Pedro Neto J. Norberto Pires A. Paulo Moreira Industrial Robotics Laboratory-Mechanical Engineering Department POLO II University of Coimbra Coimbra Portugal Institute of Systems and Robotics (ISR)-Department of Electrical and Computer Engineering University of Porta Porto Portugal

Most of industrial robots are still programmed using the typical teaching process, through the use of the robot teach pendant. In this paper is proposed an accelerometer-based system to control an industrial robot using two low-cost and small 3-axis wireless accelerometers. These accelerometers are attached to the human arms, capturing its behavior (gestures and postures). An Artificial Neural Network (ANN) trained with a back-propagation algorithm was used to recognize arm gestures and postures, which then will be used as input in the control of the robot. The aim is that the robot starts the movement almost at the same time as the user starts to perform a gesture or posture (low response time). The results show that the system allows the control of an industrial robot in an intuitive way. However, the achieved recognition rate of gestures and postures (92%) should be improved in future, keeping the compromise with the system response time (160 milliseconds). Finally, the results of some tests performed with an industrial robot are presented and discussed.

International Conference on Intelligent Transportation

作者： Cristiano Premebida Oswaldo Ludwig Urbano Nunes Department of Electrical and Computer Engineering Institute of Systems of Systems and Robotics University of Coimbra Portugal

Reliable detection and classification of vulnerable road users constitute a critical issue on safety/protection systems for intelligent vehicles driving in urban zones. In this subject, most of the perception systems have LIDAR and/or radar as primary detection modules and vision-based systems for object classification. This work, on the other hand, presents a valuable analysis of pedestrian detection in urban scenario using exclusively LIDAR-based features. The aim is to explore how much information can be extracted from LIDAR sensors for pedestrian detection. Moreover, this study will be useful to compose multi-sensor based pedestrian detection systems using not only LIDAR but also vision sensors. Experimental results using our data set and a detailed classification performance analysis are presented, with comparisons among various classification techniques.

International Conference on Advanced robotics (ICAR)

作者： Joao P. Ferreira Manuel Crisostomo A. Paulo Coimbra Institute of Systems and Robotics Department of Electrical and Computer Engineering University of Coimbra Portugal

This paper introduces two new important issues to be considered in the design of the zero moment point (ZMP) reference trajectory for the sagittal plane balance control of an autonomous walking biped robot with an human-like gait. ZMP trajectory reference generation is very important in the design and balance control of the walking of a biped robot. ZMP reference generation algorithms based on the Linear Inverted Pendulum Model (LIPM) and moving ZMP references in the swing phase have already been proposed with the ZMP trajectory during the swing phase being designed moving along a symmetric trajectory relative to the center of the foot. It was verified experimentally that in the human gait the ZMP trajectory moves along the foot in a way that it is shifted forward relative to its center. To take this into account a shift parameter is then proposed to move forward the X ZMP trajectory reference during the swing phase. It was also verified experimentally that in the human gait the ZMP trajectory amplitude depends on the swing time. Its variation law has been determined experimentally and it was verified that this range decreases as the swing time increases, reducing to zero for a static gait. It is then proposed a parameter H to take into account this variation with the swing time of the gait. In order to evaluate and compare the performance of the X ZMP trajectory references and the natural movement two performance indexes are proposed.

International Conference on Advanced robotics (ICAR)

作者： Joao P. Ferreira Manuel Crisostomo A. Paulo Coimbra Institute of Systems and Robotics Department of Electrical and Computer Engineering University of Coimbra Portugal

This paper describes the control of an autonomous biped robot capable of pulling a mass in the sagittal plane. The sagittal balance control uses an 8-link model of the robot, which is difficult to apply in real time due to the excessive computational effort. To solve this problem it is used a support vector regression (SVR) controller, which is able to perform the balance control in real time. As the ZMP balance control is non-linear, an SVR is appropriate. An SVR calculates the optimal hyper plane for the training data and computes faster than several other artificial intelligence techniques. An SVR that was trained based on experimental and simulation data, is used. This SVR uses the zero moment point (ZMP) position and its time variation as inputs, and the sagittal angle correction of the robot's body is obtained as the output. The ZMP is obtained making use of the force distribution on four force sensors placed under each robot's foot. This controller combines the use of the ankle and torso joints movements to correct the ZMP. The gait implemented in this biped is similar to a human gait that was acquired and scaled to the robot size. In this paper some experiments are also presented and the results show that the used gait combined with the SVR are appropriate to be used in the control of the biped robot, even when it drags a mass of about 65% of its own weight.

作者： Joao P. Ferreira Manuel Crisostomo A. Paulo Coimbra Institute of Systems and Robotics Department of Electrical and Computer Engineering University of Coimbra Portugal

This paper describes the control of an autonomous biped robot capable to be subjected to external forces applied in the sagittal plane. A 1st order Takagi-Sugeno-Kang (TSK) type neuro fuzzy net, that was trained based on experimental and simulation data, is used. This net uses the zero moment point (ZMP) position and its variation as inputs, and the sagittal correction of the robot's body is obtained as the output. This control method is more accurate than the method based on an inverted pendulum model, which is based on a single mass concentration. The ZMP is obtained making use of the force distribution on four force sensors placed under each robot's foot. The gait implemented on our biped is similar to a human gait. A human gait was acquired and adapted to the robot size. In this paper some experiments are presented and the results show that the presented gait combined with the TSK neuro fuzzy net is appropriate to be used in the control of the biped robot, with and without an applied external force.

Identity and expression recognition on low dimensional manifolds

IEEE International Conference on Image Processing

作者： Pedro Martins Jorge Batista Institute of Systems and Robotics Department of Electrical Engineering and Computers University of Coimbra Portugal

A solution for identity and facial expression recognition is proposed using a two stage classifier approach using low dimensional representation of the geometry of the face. Face geometry is extracted from input images using Active Appearance Models (AAM) and low dimensional manifolds were then derived using Laplacian Eigen-Maps (LE) resulting in two types of manifolds, one for model identity and the other for person-specific facial expression. The first stage uses a multiclass Support Vector Machines (SVM) to establish identity across expression changes. The second stage deals with person-specific expression recognition, and is composed by a network of seven Hidden Markov Models (HMM) displaced in parallel, each one specialized on the several facial emotions analysed. The decision was made by the sequence that yielded the highest probability. For evaluation proposes a database was build consisting on 6770 images captured from 4 people exhibiting 7 different emotions. The identity overall recognition rate was 96.8%. Facial expression results are identity dependent, and the most expressive individual achieves 81.2% of overall recognition rate.

IEEE International Workshop on Robot and Human Communication (ROMAN)

作者： Jose Prado Luis Santos Jorge Dias Institute of Systems and Robotics Department of Electrical Engineering and Computers University of Coimbra Portugal

Human-robot interaction approaches like face detection, face recognition, pedestrian detection are widely known in robotics field; however often they lead to performance problems. Additionally, false positive and false negative problems are commonly associated to bad illumination and strong featured images. Moreover background segmentation approaches are frequently used to solve this problem on static camera surveillance. Though all these approaches are unable to effectively deal with the constant background changes that certainly happens when the camera sensor is installed on a mobile robot. Hence, in this work we propose a stereo vision dynamic background segmentation solution to this problem.

IEEE International Conference on robotics and Biomimetics

作者： Mahmoud Tavakoli Lino Marques Anibal T. de Almeida Institute of Systems and Robotics Department of Electrical and Computer Engineering University of Coimbra Coimbra Portugal

Pneumatic artificial muscles also known as ldquoPAMrdquo and ldquoPMrdquo, are famous as very light actuators in the current literature. The reason stated in the literature for such claim is their lower ldquopower to weightrdquo ratio compared to other type of actuators namely pneumatic cylinders and electrical motors. However using the ldquopower to weightrdquo ratio of actuators for claiming the lightness of an actuator is questioned in this paper, and a new approach for such comparison is introduced. In this paper a comparison study was made between electrical rotary actuators and PMs on the basis of the taualpha value. It is showed that claims which consider PMs as lighter actuators compared to the other types of actuators are not precise and are highly questionable since some factors are neglected in comparison between the weight of the actuators.
