THE AUTONOMOUS GOLF PLAYING MICRO ROBOT: WITH GLOBAL VISION AND FUZZY LOGIC CONTROLLER

N. G. Jabson/ K.G. B. Leong/ S. W. Licarte/ G. M. S. Oblepias/ E. M. J. Palomado/ E .P. Dadios

This paper presents design concepts in developing an Autonomous Golf Playing Micro Robot. The robot moves autonomously using 2 DC motors controlled by a remote PC using fuzzy logic system. A servomotor is used for the motion of the putter in hitting the golf ball. A microcontroller is used to process the information sent by the computer through RF communication and drive the robot motors for appropriate motions. The robot plays golf` in a defined environment and avoids obstacles. A real golf bal(..)

MULTI-TARGET, MULTI-SENSOR TRACKING BASED ON QUALITY-OF-INFORMATION AND FORMAL BAYESIAN FRAMEWORKS

Juo-Yu Lee/ Kung Yao

We consider a multi-target tracking problem that aims to simultaneously determine the number and state of mobile targets in the field. Conventional paradigms tend to report only the existence and state of targets according to centralized detection and data fusion. On the contrary, we investigate a multi-target, multi-sensor scenario in which (a) both the number and the state of the targets are unknown a priori; and (b) the detection with respect to targets is employed in a distributed manner. To(..)

Advanced Predictive Guidance Navigation for Mobile Robots:A Novel Strategy for Rendezvous in Dynamic Settings

Faraz Kunwar/ Beno Benhabib

This paper presents a novel on-line trajectory planning method for the autonomous robotic interception of moving targets in the presence of dynamic obstacles, i.e., position and velocity matching (also referred to as rendezvous). The novelty of the proposed time-optimal interception method is that it directly considers the dynamics of the obstacles as well as the target in its interception maneuver: the velocities and accelerations of the obstacles and the target are predicted in real-time for p(..)

A Robot Succeeds in 100% Mirror Image Cognition

Junichi Takeno

Humans are capable of identifying their own image when reflected in a mirror. This mechanism is a mystery that has never been solved. I created a program that achieved such awareness on a robot and conducted three experiments. The first was an experiment on a self robot that imitates its own self-image reflected in a mirror. The second experiment had a robot imitating another robot of the same type which was made to perform the same behavior. The last was an experiment using two robots of the sa(..)

Training Data Compression Algorithms and Reliability in Large Wireless Sensor Networks

Vasanth Iyer/ Garimella Ram Murthy/ M.B. Srinivas

With the availability of low-cost sensor nodes there have been many standards developed to integrate and network these nodes to form a reliable network allowing many different types of hardware vendors to coexist. Most of these solutions however have aimed at industry-specific interoperability but not the size of the sensor network and the large amount of data which is collected in course of its lifetime. In this paper we use well studied data compression algorithms which optimize on bringing do(..)

Impedance Behaviour of a Microporous PMMA-Film `Coated Constant Phase Element' based Chemical Sensor

Karabi Biswas/ Litty Thomas/ Sourabh Chowdhury/ Basudam Adhikari/ Siddhartha Sen

In this work, it has been attempted to characterize a new type of impedance sensor called constant phase element (CPE) sensor; which has microporous PMMA- lm coating on the electrode surface. It has been shown that the `constant phase angle (CPA)' behaviour is primarily due to the porous structure of the electrode surface. And the phase angle at the output of the sensor changes with thickness variation of the PMMA coating and ionic property of the medium in which the sensor is dipped in. The sen(..)

SENSITIVITY IMPROVEMENT OF WIRELESS PRESSURE SENSOR BY INCORPORATING A SAW REFLECTIVE DELAY LINE

Haekwan Oh/ Weng Wang/ Keekeun Lee/ Ikmo Park/ Sang Sik Yang

this paper presents a wireless surface acoustic wave (SAW) pressure sensor on 41oYX LiNbO3 for tire pressure monitoring system (TPMS) application, in which a reflective delay line composed of an interdigital transducer (IDT) and several reflectors was used as the sensor element. Using the coupling of modes (COM), the SAW reflective delay line was simulated, and the optimal design parameters were determined. The fabricated 2.4GHz SAW sensor was wirelessly characterized by the network analyzer. Sh(..)

Implementation of linear trace moisture sensor by nano porous thin film moisture sensor and NLAmp

Dilip Kumar Ghara/ Debdulal Saha/ Kamalendu Sengupta

Almost all type of moisture sensors has a non-linear response. With out linearization it is difficult to apply such a non-linear sensor in electronics circuits, specially in analog electronics. Non linear sensor and transducers characteristic can be linearized using analog electronics or digital electronics. In this paper a method of linearization of such non-linear sensors characteristics using analog electronics is described. Theoretical explanation of the methods and its verification by exper(..)

DETECTION OF TRANSVERSE CRACKS IN A COMPOSITE BEAM USING COMBINED FEATURES OF LAMB WAVE AND VIBRATION TECHNIQUES IN ANN ENVIRONMENT

Ramadas C./ Krishnan Balasubramaniam/ M. Joshi/ C.V. Krishnamurthy

The detection, location and sizing of transverse cracks in a composite beam, by combining damage features of Lamb wave and vibration based techniques in artificial neural network (ANN) environment, using numerical finite element model, is discussed. Four damage features, time of flight (TOF) and amplitude ratio, which are Lamb wave based features and first and second natural frequencies, which are vibration based features were used as input to ANN. The output of ANN was crack location and depth.(..)

DEVELOPMENT OF AN FPGA BASED SMART DIAGNOSTIC SYSTEM FOR SPIROMETRIC DATA PROCESSING APPLICATIONS

Shubhajit Roy Chowdhury/ Dipankar Chakrabarti/ Hiranmay Saha

The paper describes the development of an FPGA based fuzzy processing system for pulmonary spirometry applications predicting the approaching obstructive or restrictive pulmonary disorder of the patient before criticality actually occurs. The system employs a smart agent that accepts the Peak Expiratory Flow Rate (PEFR), Forced Expiratory Volume in 1 second (FEV1) and Forced Vital Capacity (FVC) data of patients. In order to speed up the computation process, hybrid parallel data processing archi(..)

DESIGN AND OPTIMIZATION OF BULK MICROMACHINED ACCELEROMETER FOR SPACE APPLICATIONS

Shubhajit Roy Chowdhury/ Dipankar Chakrabarti/ Hiranmay Saha/ Thampi Paul/ Jaspreet Singh/ M. M. Nayak/ K. Rajanna/ M. Sasi Kumar

The accelerometers used for Inertial Navigation in satellite launch vehicles demand excellent performance in terms of sensitivity, noise immunity, linearity, bias and scale factor stability over time and environmental changes. Detailed and in-depth design of the microstructure by computer simulation is required to ensure structural integrity and reliability of the microstructure. The microstructure of the accelerometer consists of a proof mass suspended from the mounting frame by beam springs. E(..)

Dynamic Measurements and Dynamically-Functioning Objects-Time Is to Look at Reality

G. Abramchuk/ K. Abramchuk

It is shown that many dynamic tests and measurement technologies base on a changing measurement equation and that internal and external disturbances may change the dynamic functional of the same object and that the reaction of measurement transducer (measurement channel) changes not only in dependence on type of loads. The reasons are given which cause methodical metering errors and make it difficult to build idealized smart sensing and intelligent systems
