Abstract:
This is a simple technique that can meet the needs of the system purposes like nonlinearity, MIMO, coupling eff ect, uncertainty and complexity. FCM method is the combination of fuzzy systems and neural networks methods which contains the robust properties of both methods. As the structure of FCM has the ability to design the controller based on the needs of the system and what is expected from the system to do, not how it works, it could be a suitable solution for nonlinear MIMO systems. The structure of FCM is a graph structure with simple mathematics based on tendencies or goals of the system. Th erefore, the designing of the controller is not involved with complexity of the system and complex mathematical analysis for deriving the control law. In this study, in control scenario by FCM, the inputs and outputs of the system with other eff ective parameters in the process like actuators could be considered as concepts (MIMO characteristic). Th e nodes are connected to each other based on the relationship or eff ect of them on each other (possible coupling eff ects). Finally, the control signals are applied to the nonlinear dynamic model of the system. Consequently, the nonlinear MIMO controller with simple mathematics and algorithm by considering coupling eff ect could be designed based on soft computing method of FCM in order to apply on nonlinear MIMO systems. Th e benefi ts of FCMs are fast convergence due to the less mathematical calculation and analysis and helping to omit the artifi cial decoupling of variables due to its construction, accordingly the accuracy and sensitivity of control can be increased.

Abstract:
Climbing capability is a characteristic that robotic researchers have been intensely pursuing in the last decade for climbing robots. Emphasis has been on minimizing energy expenditure, increasing payload and traversing diff erent wall materials. Using the Bernoulli principle as inspiration, important principles are revealed for reliable maneuvering on vertical structures. An experimental identifi cation of a model for a Bernoulli principle-based holding force is described. To quantitatively evaluate requirements of a Bernoulli pad to achieve attachment on a wall, this paper presents the force analysis and conducts experimental verifi cation for a commercially available Bernoulli pad. By designing and using a test bed, optimal holding force that ensures complete attachment of the pad is defi ned and experimentally verifi ed. Factors that infl uence the holding force such as fl uid media, frictional force, robot state, air speed, height of pad from surface and density variations are experimentally investigated and their causes and eff ects are established. Th e methods proposed in this study are valuable in guiding the design of pneumatics-based adhesion devices such as wall-climbing robots. Th e results from the experiments would then lead to the design of an adaptive force which would enable diff erent fl uid media to be used therefore increasing the versatility of the adhesion system. Th ey would also enable optimization of the Bernoulli principle therefore increasing holding force and payload. Th e cause and eff ect of these parameters were confi rmed through fi nite element analysis using ANSYS and simulation using Matlab.

Abstract:
Rayleigh’s distribution is mainly used when fading wireless medium does not have proper line of sight (LOS) path and is dominated by a large number of non-line of sight (NLOS) paths due to refl ections of the received signal. Also because of relative motion of the base station and mobile station, a random frequency shift is generally introduced in the carrier, which can be realized in terms of Doppler spread. In case of Rayleigh’s fading channels, generally two critical problems arise in receiver design those are accurate estimations of channel coeffi cients followed by mitigation of channel impairments like inter symbol interference (ISI) and fading in presence of user mobility. Th e accuracy of estimated channel state information (CSI) is really crucial to design robust equalizer for reconstruction of bit sequence and the equalizer performance is aff ected by the fading rate and Doppler spread. Th e main research is oriented towards the exploitation of underlying sparseness of block adaptive fi lters through L0-norm penalty for accurate estimation with stable convergence which helps to design computationally effi cient adaptive models that can be eff ectively used for practical applications. Block and fast block processing can be quite eff ective techniques for outdoor fading wireless environment with proper choice of modulation formats.

Title: A detailed kinematic analysis of a 6-articulated industrial robot
Time : 11:50-12:10
Biography:
Randika K W Vithanage has received his BSc degree in Mechanical Engineering from University of Moratuwa, Sri Lanka in 2010.

His research interests include industrial robots, robotic sensing, and manipulation of robots in unstructured environments.
Abstract:
Due largely to the growing emphasis in academic research on industrial robots and their applications, it is oft en required by researchers to understand and examine the kinematic aspect of such robots. Obtaining both forward and inverse kinematic models of a given industrial robot could be a tedious and intricate task. Th erefore, this paper presents a detailed kinematic analysis of a 6-axis industrial robot that commonly found in present-day industry and research laboratories. Th e proposed kinematic solutions have been validated against the simulation soft ware provided by robot’s supplier and an error analysis has been done to ensure the accuracy. Th ere are particular models of robots which are well discussed in the fi eld of robotic research and also within the domain of kinematic analysis. Th e Puma 560 by Unimation, also known as “white rat” of robotics is one of such robots which catalyzed robotic research for decades, and well examined in textbooks and research articles. However, the eminence of such robots is gradually being replaced by modern 6-axis industrial robots. Perhaps due to its size, prize, availability or consideration of health and safety aspects, the Fanuc LR Mate 200iD is becoming increasingly popular in the industry as well as in the research laboratories. Alternatively, there are a limited number of research articles which examine the kinematics of present day industrial robots. Further, the majority of those articles barely discusses the results and lacks the scientifi c validation of proposed solutions. Th erefore, the main focus of this article was to generate and validate the both forward and inverse kinematic models of a popular and modern industrial robot – the Fanuc LR Mate 200iD.

Abstract:
Piezoelectric self-sensing actuators (SSAs) have been extensively used in vibration control of fl exible structures over the last three decades. Compared to separated sensor/actuator systems, the SSA is simple, robust, and cost-eff ective. According to the literature, the specially designed electric circuit, referred to as a bridge circuit, is required to realize the concept. A method of achieving self-sensing capability without a bridge circuit is proposed by utilizing a velocity observer, and then the vibration velocity of a SSA can be estimated by the measured voltage and current signals. Th us, the SSA active vibration control can be implemented without using a physical velocity sensor to achieve the required vibration suppression based on feedback control design. Th e SSA vibration suppression performance is highly dependent on the equivalent mechanical admittance, which consists of equivalent mass, stiff ness, and damping. Furthermore, the equivalent stiff ness and damping will be directly influenced by the controller parameters. Th us, the SSA vibration suppression performance can be adjusted by the control design. The experimental results show that the proposed method can eff ectively reduce the structural resonance phenomenon when the controller parameters of the SSA are properly designed with a required mechanical admittance.

Title: A universal robotic control system using reinforcement learning with limited feedback
Biography:
Michael Truell is presently at the Horace Mann School in Bronx, NY.
Abstract:
A mobile robot deep reinforcement learning system is created that converges on common robotic tasks using four times less feedback than pre-existing solutions. Th e system achieves this leap in effi ciency through context-aware action selection and aggressive online hyper-parameter optimization while still maintaining performance on embedded hardware. A core algorithm of deep wire fi tted q-learning is supplemented with active measurement of robot uncertainty, defi ned as the derivative of error between expected and received reward. Th is uncertainty value directly scales the temperature of Boltzmann probabilistic exploration policy in addition to the learning rate of stochastic gradient descent. Furthermore, to provide generality across robots and tasks, neural network topology is effi ciently evolved throughout training and evaluation. Finally, experience replay is extended to changing environments and is integrated with our uncertainty value. Human operators successfully trained the system on multiple robots in a matter of minutes to perform tasks such as driving to a point with a diff erential drive system, following a line using holonomic Swedish wheels or playing ping pong with a robot arm. All are without any manual hyperparameter adjustment in both simulation and hardware.

Abstract:
The piezo actuator is using in the automatic control system in the scanning tunneling microscopes, the scanning force microscopes and the atomic force microscopes for the nanotechnology. Th e piezo actuator is the piezo mechanical device intended for the actuation of the mechanisms, the systems or the management based on the piezo eff ect, converts the electrical signals into the mechanical movement and the force. Th e correcting devices are chosen the high quality of the automatic control systems of the deformation the piezo actuator. Th e analytical expressions for the suffi cient absolute stability conditions of the system with the hysteresis nonlinearity of the electro-magneto-elastic actuators are written using the Yakubovich absolute stability criterion with the use of the derivative for the characteristic deformation of the piezo actuator. Th e Yakubovich criterion is the development of the Popov absolute stability criterion. For the stable control system on Lyapunov, the Yalubovich absolute stability criterion for the systems with the single hysteresis nonlinearity provides the simplest and pictorial representation of results of the investigation of the stability and the possibility of the synthesis of the correcting devices of the system ensuring the stability of the strain control systems with the piezo actuator. In the condition of the absolute stability of the control system for the deformation the piezo actuator of the nanomanipulator is used the value of the tangent of the angle of the tangent line to the hysteresis nonlinearity for the piezo actuator. Th e stationary set of the automatic control systems of the deformation the piezo actuator is the segment of the straight line. Th e conditions of the absolute stability of the automatic control systems with the piezo actuator in the case of longitudinal, transverse and shift piezo eff ect for the hysteresis characteristic of deformation of the piezo actuator are obtained. Th e obtained absolute stability condition with the use of the derivative for the characteristic deformation of the piezo actuator for the automatic control system with the piezo actuator allow one to estimate and calculate the characteristics of the correcting devices of the control system of the deformation the piezo actuator.

Abstract:
Color is a powerful form of communication among human beings. Sociable robots that live and coexist with humans must also learn colors from the society it lives. A lot of research has been performed to enable computer, as the brain of a robot, to learn colors. Most of them rely on modeling of human color perception and mathematical complexities. Diff erently, this work targets on developing the capability of the computer to use machine learning approaches to learn the colors through human interaction. Th e diff erent colors which is being detected in the camera is processed by using image processing tool OpenCV and the most dominant color of the picture is identifi ed and displayed in the system. Th e user can now teach the computer the difference between the appropriate colors using the RGB values. Th erefore, although at the beginning, the computer does not know any colors, eventually through interaction, it learns numerous colors which will indicate the shared color learning with humans in the society. Aft er teaching the computer a number of times, it is able to classify the colors by matching with RGB values for that particular color from the database. If the color does not exist, the computer identifi es the closest possible color using the unsupervised machine learning technique k-means clustering. Aft er learning colors from the society, the developed algorithm is implemented in the NTU Singaboat, which is an Unmanned Surface Vehicle (USV) built for competing in the Maritime RobotX Challenge.

Abstract:
Intelligent Autonomous Systems (IAS) are highly cognitive, refl ective, multitask-able, and eff ective in knowledge discovery. Examples of IAS include soft ware that is capable of automatic reconfi guration, autonomous vehicles, network of sensors with reconfi gurable sensory platforms, and an unmanned aerial vehicle respecting privacy by deciding to turn off its camera when pointing inside a private residence. Research is needed to build systems that can monitor their environment and interactions, learn their capability, and adapt to meet the mission objectives with limited or no human intervention. Th e systems should be fail-safe and should allow for graceful degradations while continuing to meet the mission objectives. Th is presentation will advance the science of autonomy in smart systems through enhancement in real-time control, auto-confi gurability, monitoring, adaptability, trust. I will present research ideas in smart autonomy, Multi-intelligence (MINT) Enterprise Analytics, and Rapid Autonomy prototype among others. Th e main objective is to realize a vision based on the following approaches: Employ machine learning techniques on sensor and provenance data to learn and understand the underlying patterns of interaction, conduct forensics to detect anomalies, and provide assistance in decision making by on-the-fl y semantic and probabilistic reasoning; Apply advanced data analytics techniques to incomplete and hidden raw system data (provenance data, error logs, etc.,) to discover new knowledge that contributes to the success of the IAS mission; Enhance the autonomous system’s self-awareness, self-protection, self-healing, and self-optimization by learning from the knowledge discovered through dataanalytics and Utilizing blockchain technology for storing provenance data for providing monitoring, trust, and verifi cation, using the WaxedPrune system developed for Northrup Grumman.

Abstract:
The book with the title, “Th e Sciences of the Artifi cial”, is by Nobel Prize winner in 1978, Simon Herbert. At issue is cognitive processes and analytics from inherent hierarchical system complexity. We may be determining the extent of hierarchical nature and properties, perhaps including or determining evolution along the lines of geneology. First we address how inherently hierarchical various sources of data can be. Considered are time series that are fi nancial, environmental, biomedical, and texts that are from literature, from accident reports, and psychogically related dream reports. Th e use and benefi t of taking hierarchical structure fully into account includes the following: how high dimensional or sparse data become hierarchical, and application can be for proximity and related searching, leading to nearest neighbour regression. But far more than that is ultrametric regression, taking into account the ultrametric topology associated with hierarchical structure. For our cognitive processes and analytics, ultrametric regression is how cognitive and analytical processing determines such system properties for regression purposes. By using contiguity-constrained, i.e. here, chronological, hierarchical clustering, then through multivariate time series, and changepoint analysis, hierarchy expresses changes at varying scales. At issue, quite generally, are multivariate time series. Furthermore, our partitioning of the chronologically constrained hierarchical clustering, so as to segment the multivariate time series, and determine changepoints, this is carried out using a wavelet transform in the ultrametric topological space. Th e case study here, of ultrametric wavelet regression of multivariate time series, is through application to Colombian confl ict analysis.

Abstract:
Modern production systems utilize robotic and automation systems including automatic guided vehicles (AGVs) for a variety of material handling tasks. A low-cost AGV was initially designed for an assembly line at General Motors South Africa (GMSA). Th is paper presents the latest development and modifi cations of the AGV design.

However, it could also be employed to deliver unique or unusual parts between production lines in a more complex production environment. Th e improved AGV controller is based on a BeagleBone Black, which uses an ARM cortex-A8 processor for navigation, obstacle detection and logic processing. Th e navigation is achieved with a magnetic sensor that follows magnetic tape. Th e ultrasonic sensors are used to develop a safety zone ahead of the AGV to avoid obstacles. Th e proposed AGV design meets the criteria for an effi cient and low-cost autonomous material handling system. Th e developed AGV is capable of transporting tasks in various industrial environments and it can be easily reprogrammed to cater for very specifi c scenarios.

Abstract:
This article refers to a phenomenological model of a batch reactor. Using an energy balance model it was possible to predict the heating and cooling behavior inside the reactor and how the temperature varies with the applied voltage. Th is work will be used for later emphasis on polymer syntheses, especially the hydrolytic synthesis of caprolactam, in order to obtain a product with a higher value-added market, nylon 6. Given the diffi culty of temperature control when operating with nylon 6, silicone oil (nylon-like characteristics) was used for system testing and data collection. In this way, the system boils down to a heating tank, with heating via electrical resistance. Th us, the focus of the present study will be on modeling the reactor using silicone oil. Th e study will be done obtaining dynamic measurements of temperature in order to be able to present a phenomenological model of the reactor. For the validation of the model, we used data collected in the plant from a steptype test. In this way, this text aims to develop the phenomenological model of the system in order to better understand the dynamics of the heating and thus enable future control studies. Th e model represented a satisfactory behavior of the reactor in question, presenting an average relative error of 4.3%.
