It is desirable to measure the interaction force of manipulator to its environment for controlling purpose. A 12 DOF (degree of freedom) force/torque sensor, which integrates a six-axis accelerometer in the six-axis wrist force/torque sensor, is designed to solve the problem in this paper. The sensor can measure all the three linear accelerations a/sub x/, a/sub y/, a/sub z/ and three angular accelerations a/sub x/, a/sub y/, a/sub z/ simultaneously in 3D space besides offering information of the forces F/sub x/, F/sub y/, F/sub z/ and the moments M/sub x/, M/sub y/, M/sub z/. We also give a kinetic model of six-axis wrist force/torque sensor while the end manipulator is in dynamic state. And the extraction method for interaction force from six-axis wrist force/torque sensor is presented. Some experiments are carried out to test the sensor and verify the data fusion method. The results show that the sensor could output decoupled interaction force, and identify the state of grasped object.","PeriodicalId":297178,"journal":{"name":"International Conference on Information Acquisition, 2004.

The system consists of a CO/sub 2/, laser focusing system and a 3D precision positioning platform. The CO/sub 2/ laser focusing system can regulate a laser beam which is of high-energy and of micron dimension in beam diameter, and the movement precision of the 3D platform is of micron dimension. The fabrication of 3D microchannel system in PMMA (polymethyl methacrylate) can be realized by controlling the CO/sub 2/ laser and the platform. A special 'sacrificial mask' process was used to produce translucent channels of micron dimensions with low surface roughness using the developed system. The effectiveness of our developed system is confirmed by the experimental results. Potentially, our developed system can be automated to produce 3D micro channels in PMMA substrates without the requirement for the costly and time-consuming lithography and hot-embossing processes that are needed currently.","PeriodicalId":297178,"journal":{"name":"International Conference on Information Acquisition, 2004.

Firstly, an image based measurement system is set up. Secondly, segment the captured image and extract bubbles, and then fit the extracted bubbles' area by minimum mean square error (MMSE) with ellipse fitting. Finally, calculate bubble volume by an ellipse fitting with MMSE, and measure bubbles velocities and kinetic locus by tracking and locating them in each frame. A smooth kinetic locus of each bubble is obtained by using cubic spline function to connect the discrete centroid points thus a visual measurement of flow field is guaranteed. The experiment results show that the proposed method both has higher accuracy in stationary and dynamic parameters measurement.","PeriodicalId":297178,"journal":{"name":"International Conference on Information Acquisition, 2004.

The cognitive map, which is constructed by the linking features of the short lines, acts as a reasoning tool to judge whether some of the short lines can be treated as a single long line. The reasoning results of the constructed fuzzy cognitive map would form the meaningful line features, which are component parts of some basic shapes. The concept functions in the fuzzy cognitive map represent the changing range of the composing part of the basic shapes. And the construction of the fuzzy cognitive map network represents the relationships among those composing part of the line features. So, there appears the method of forming the basic line features based on fuzzy cognitive map. By matching reasoning with that model, belief of the combination of short lines into long ones can be obtained. Only when belief is greater than certain threshold, can the lines be regarded as the line features. Experiments show that this method has many advantages, such as simplicity, robustness, small amount of computation, and so on. In addition, this method is comparatively insensitive to rotation, shift and scale of the object. The method we propose in this paper is in a measure the perfection and extension of methods currently used in basic shapes recognition.","PeriodicalId":297178,"journal":{"name":"International Conference on Information Acquisition, 2004.
