In recent years, dynamics model and control of space robot system are the hot topics in the research field. In this paper, a new dynamics model and control strategy of space robotic system with a flexible manipulator and a liquid fuel tank are investigated. Based on Lagrange equation method, the dynamics model of the space robotic system coupling with liquid sloshing, flexibility vibration and base movement is derived. The elastic deflection of the flexible manipulator is described by the assumed mode method and equivalent mechanical model is adopted instead of liquid sloshing under the environment of low-gravity. The inverse dynamics control algorithm combined with PD control method is performed to solve the trajectory tracking problem. Some simulation results are given to verify the effectiveness of the proposed method.

Combined Tactile Sensing with Optical Mouse Sensor

SICE Journal of control, Measurement, and system Integration 2009年第2期2卷 117-121页

Instead of functioning as a part of a pointing device for computers, the optical mouse sensors are employed for combined tactile sensing in this study. Based on the experimental characteristics of optical mouse sensors, with a step-by-step table-look-up method, a combined tactile sensing system is proposed. When an object surface is moved underneath the optical mouse sensor, the translation direction, the category and the height of the object surface can be obtained with the recorded output of the optical mouse sensor based on a predefined data table.

This paper proposes a simulator-based foresight control approach for nonlinear plant based on system identification. In the proposed method, as a main part of the simulator-based foresight control system, a simulator of an exact plant model of non-affine nonlinear plant is first constructed. If relative degree of disturbance is smaller than control input, servo type filter will be then installed in series of disturbance line in order to adjust relative degree. Next, a control target equation which defines pole assignment for stable output error convergence is determined. Based on this control target equation, the control input for non-affine type nonlinear plant is generated. In this paper, the control of a boiler was implemented by use of the proposed method. The simulation results verified the effectiveness of the proposed method. © 2009 SICE.

A method for detecting spikes and slow burst in photic evoked electroencephalogram (EEG) was proposed. The spikes were detected by combining methods of the morphological filter and the similarity coefficient in the time domain. The slow burst was detected by using pole of AR model in the frequency domain. The proposed method was applied for the photic evoked EEG data containing spikes and slow burst, and brought satisfactory coincidence with the results interpreted by a qualified electroencephalographer. © 2009 SICE.

Complex and adaptive behavior of population emerges in social insects. Especially in ants, pheromone communication is the key to understanding their swarm intelligence. This paper proposes a swarm robot system based on pheromone communication and reports our current status of development of the robot system. We believe that the system could be used in swarm robotics and complex systems education. ©ISAROB 2009.

We have investigated the nanofabrication of three-dimensional (3D) chemical vapor deposited (CVD) diamond molds in Electron Cyclotron Resonance (ECR) oxygen ion beam etching technologies using polysiloxane [-R2SiO-]n as an electron beam (EB) mask and a room-temperature (RT)-imprint resist material. The polysiloxane exhibited a negative-exposure characteristic and its sensitivity was 5:5 × 10 -5 C/cm2. The maximum etching selectivity of polysiloxane film against diamond film was 4.7, which was obtained under the following ECR oxygen ion etching conditions: ion energy of 400 eV, ion incidence angle of 0 ° , microwave power of 100 W, gas pressure of 1:4 × 10 -2 Pa and stage temperature of 24 ° C. The diamond molds of cone and tetragonal pyramid dots were fabricated with polysiloxane mask in EB lithography technology using the RT-nanoimprint lithography (NIL) process. The dots are 500, 600, 700, 800, 900 nm in diameter and width respectively. The pitch between the dots is 2 μm, and each dot has a height of about 1 μm. It was found that the optimum imprinting pressure and its depth obtained after the press for 5 min were 0.5 MPa and 0.5 μm respectively. The resulting diameter of each imprinted polysiloxane pattern was in good agreement with that of the 3D-diamond mold. We carried out the RT-NIL process for the fabrication of diamond nanopatterns, using the 3D-diamond molds that we developed. © 2009 The Surface Science Society of Japan.

Quantitative analysis and detection of abnormalities for electroencephalogram (EEG) recordings during evoked activities are essential for clinical diagnosis on neurological disorders. However, the process of interpreting EEG is time consuming and requires experienced electroencephalographers (EEGers). In this study, a method of automatic EEG interpretation during hyperventilation was proposed. The purpose is to provide a quantitative interpretation of EEG which is able to conform to EEGers' visual inspection. The final integrated results of automatic interpretation were compared with EEGers' evaluation, and showed high consistence. © 2009 SICE.

A chemical kinetic model for high pressure combustion of H 2/O2 mixtures has been developed. Some of the rate constants important in high pressure conditions were updated. Particular attention has been paid to different channels of the H+HO2 reaction, and to the third body efficiency in the H+O2+M and H+OH+M reactions. An analysis of the performance of an updated model is presented by comparing with various experimental data. Although the present model could reproduce most of shock tube data of ignition delay with variety of bath gases, there is still some discrepancy in the pressure dependence of flame speed between model predictions and recent experimental data. © 2009 by the American Institute of Aeronautics and Astronautics, Inc.
