In this paper, the vibration characteristics of the digging colter for the rhizomatic Chinese medicinal plants harvester are researched, and a modal analysis is completed on the ANSYS 11.0. The main modal characteristics of the digging colter are given in the range of the most impressionable frequencies The vibratory response of the structure under internal or external influence are predicted, and the low-orders inherent frequency and the deformation of the system are obtained. The low-order vibration mode of XY side and XZ side are the most possible response modes. The low-order mode of XY side produced a lateral oscillating deformation, and the low-order mode of XZ side produced a bending deformation. The analysis results provide foundations for further theoretical analysis and structural design of the digging colter.

This paper describes the design of a new robot head which has three special parts for emotional expression. Recently, the emotion of robots has become an issue of interest in the field of robotics. This robot head, EEEX (Exaggerating Emotion EXpresser) is developed to efficiently express various emotions. EEEX is useful in the Human-robot interaction. EEEX has 3 special elements that humans do not possess to clearly express emotions. The first is arm-type antennae which consist of a 3-DOFs link system on each side to make dynamically emotional movements. They are specialized parts to show emotion by copying the human's arm motion. Second, emoticon-eyes help to represent emotions intuitively since the eyes are the most important parts to convey emotions. Lastly, exaggerating jaw & cheeks when expressing exaggerative emotions should assist in emotional expression as well, particularly surprise and anger. These 3 parts, the arm-type antennae, emoticon-eyes and exaggerating jaw & cheeks, would help human to recognize a robot's emotions more clearly.

The ISiMI AUV developed in KORDI (Korea Ocean research and development Institute) is a test-bed to develop and validate various algorithms and instruments required to AUV. For the fast experimental feedbacks of the AUV technologies, ISiMI is designed to be a small vehicle enough to cruise in the Ocean engineering Basin in KORDI and to be handled by on or two persons. In this paper, design and implementation of ISiMI AUV is introduced. A series of test results in Ocean engineering Basin and the discussions about the results is presented with the comparisons of simulation and experimental output.

This paper presents a total solution on EMG signal-based walking phase recognition for people with lower limb disability. Various environmental factors such as sensed location, walking speed, and ground inclination are taken into consideration in all the phases of signal sensing, feature extraction, feature selection, and classification. Based on analysis on fourteen well-known feature extraction methods in varying environmental situation, this paper proposes a methodology for selecting a good feature set, and then demonstrates effectiveness of the proposed approach with the classification results.

This paper presents the components and overall architecture of the ubiquitous robot (Ubibot) system developed to demonstrate ubiquitous robotics, a new paradigm for integrated services. The system has been developed on the basis of the definition of the ubiquitous robot as that of encompassing the software robot Sobot, embedded robot Embot and the mobile robot Mobot. This tripartite partition, which independently manifests intelligence, perception and action, enables the abstraction of intelligence through the standardization of sensory data and motor or action commands. The Ubibot system itself is introduced along with its component subsystems of Embots, the position Embot, vision Embot and sound Embot, the Mobots of Mybot and HSR, the Sobot, Rity, a virtual pet modeled as an artificial creature, and finally the middleware which seamlessly enables interconnection between other components. Three kinds of experiments are devised to demonstrate the fundamental features, of calm sensing, context awareness and seamless service transcending the spatial limitations in the abilities of earlier generation personal robots. The experiments demonstrate the proof of concept of this powerful new paradigm which shows great promise.

Recently, there has been an increase in the development of fire searching robots for indoor spaces such as the basements of buildings. This paper presents the control architecture for a fire searching robot using task oriented design (TOD) methodology. TOD is the systematic methodology used to design a system which follows a purpose closely by specifying a target clearly. As indoor spaces are blocked by walls, dangerous fires with smoke, high temperatures, and the possibility of explosions make it difficult for fire fighters to gain access to the fire. For this reason, a fire searching robot is developed in this study. It takes the place of fire fighters by means of an analysis of the properties of the environment of a fire, as well as the tasks demanded by the situation. For a stable operation, the fire searching robot is controlled by remote control. The control system is divided into three parts. The first is the robot controller, the second is a controller for the remote operating device, and the third is a wireless communication system. The appropriate hardware and software was developed for each part of the control system, and the fire search robot was tested in a test environment. The tests validated the performance and usefulness of the proposed control architecture

Mr. Taylor has more than 18 years of experience in the field of research and developmentengineering. Since joining Westinghouse in 1974 he has been involved in the design and development of advanced electrical machinery including large, high power density motors for electric drive ship propulsion, pulsed homopolar generators for electromagnetic launchers, high current density contacts for switching applications, research in automated manufacturing, and robotic system development. He is currently managing a section that deals with rotating power equipment for military applications, with emphasis on thermal and electromagnetic modeling. ABSTRACT A demonstration submersible outboard electric motor/ propulsor has been designed, built, and successfully tested. This concept involves mounting a propeller directly inside a rotor of a specially designed induction motor. This motor/ propulsor has the advantages of direct seawater cooling and bearing lubrication, direct drive, shrouded propeller, variable positioning, easy access, and high maneuverability. The motor/propulsor is readily adaptable to dual, independently-controlled and contra-rotating propellers without the need for gears. The concept has been investigated conceptually for application to primary propulsion, secondary propulsion, and pod drives, for amphibious, surface, and undersea vehicles.
