In a series of studies, articulatory features used as speech attributes for automatic speech recognition systems have been shown to improve the performance. The existing articulatory features are defined by phonetician as a set of articulatory descriptions of phones, which represent some semantic information explaining how humans produce speech sounds via the interaction of different physiological...
As the Tibetan traditional game with unique connotation and characteristics of national culture, Tibetan chess plays an important role in Tibetan culture heritage and protection. Tibetan chess includes different types of chess board and regulations. Chess board is with huge branching factor, the complexity of the search space is very high. Besides, chess play record collection is important issue facing...
As a rarity of Tibetan national culture, the Tibetan-go is dying out. In order to protect and popularize this unique culture, this paper designed a Tibetan-go human-computer game software. This software is composed of board representation, movement generator, searching engine and situation evaluation modules. The Tibetan-go human-computer game is realized by c programming language. We made test between...
There has been a challenging research topic on exploring an universal set of speech attributes sharing among a large number of languages for detection-based bottom-up cross-language speech recognition. In some recent research works, articulatory features are used as an universal set of speech attributes shared across many different languages. Since they are defined by human as a set of semantic articulatory...
This paper presents a data conversion method between Kinect raw motion data and standard BVH format file. To verify the feasibility of conversion and correctness of data, the motion data in BVH format is imported into Motion Builder, 3D animation software, forming a demo animation. The results show that data conversion is workable and data are correct.
The main difficulty of Amazons games is the huge branch factor. Traditional NegaMax Search and Alpha-Beta Search can only search a few layers and can't improve the games effectively. Monte-Carlo Algorithm can improve the games but it needs a huge amount of computing. This paper studies applying UCT algorithm to the Amazons games to overcome this problem in order to balance the search efficiency and...
In this paper, the point-to-point control problem of a Prismatic-Revolute (PR) under-actuated manipulator is presented. The PR under-actuated manipulator with the first prismatic actuated joint and a second revolute passive joint can only move in the horizontal plane. According to the characteristic of the dynamic equation of the system, a new equation concerned only with generalized coordinate, velocity...
The problem of active object tracking system is discussed. A binocular vision system having the ability of actively tracking moving objects, especially human object is designed and implemented. Management software is also developed for further study. The key technologies on active tracking of one moving object by such a binocular system have been studied. The general architecture is firstly analyzed,...
Water Strider Robot is a kind of bio-inspired micro robot that can stand and move on water surface via surface tension as insect water strider. Therefore WSR can save greatly energy because avoid from the water viscous drag, that is the main resistance to hinder the boat, submarine and fish-like robot. This makes it has the features of tiny drag, high speed, great agile, capability of accessing to...
This paper discussed the design method and realization technology of an infrared remote device, which is used to control a Water Strider Robot: Water Dancer III. According to the considerations of functions and performance demanded, a detailed system scheme with the centralized control mode is designed. The Ultra-low power microchip MSP430 is worked as the main controller of the device, connected...
In this paper, the problems are discussed for shape design and position arrangement for Water Strider Robot's supporting legs are discussed. A supporting leg is approached as Euler-Bernoulli elastic curved beam and a method for designing its optimal shape is proposed by analysing elastic deformation and stress-strain. The objective of the proposed optimal method is to attain the maximum lift force...

The design method of Water Strider Robot (WSR) is discussed in the paper. A WSR prototype driven with two electric motors and tele-controlled via infrared signals is designed and successfully built. A set of algorithms for designing the size of the driving leg is also proposed. Moreover, the methods and an instance to design the structure, control system and software of the robot are present. With...
A frame of modular design problems and requirements for underactuated mechanisms is discussed as related to robotic fingers. The proposed modular mechanism is connected sequentially by series units of underactuated mechanisms, which have the feature of passive self-adaptive in grasp operation and uniformizable in design procedure. The design considerations for modular underactuated mechanism are outlined...
A manipulator with free joints is a class of under-actuated mechanisms. Control of such systems is one of major topics in robotics and control engineering. In this paper, we develop a nonlinear feedback controller to force a three-dof planar under-actuated manipulator affected by smooth, bounded uncertainties to globally asymptotically track a reference trajectory. This under-actuated manipulator...
