In this paper, we design a feedback controller to stabilize the disk-on-disk system attached to a 2-link arm. The disk-on-disk consists of two disks in which the upper disk (object) is free to roll on top of the lower disk (hand) under the influence of gravity. In addition, the center of the hand is attached to the end point of the 2-link arm enabling the hand to move in translation as well as rotation. The proposed controller stabilizes the object disk on top of the hand at a target X-Y position in a vertical plane. The dynamic model of the system is derived and the dynamic feedback linearization method is used in the design of the controller. The performance of the controller is demonstrated through simulation results.

This study compares several acoustic features for developing an automatic vowel sequence reproduction system for a talking robot, which is a mechanical vocalization system modeling the human articulatory system. Matlab-based control system is used to analyze a recorded sound and drives the articulatory motors of the talking robot. A novel method based on short-time energy analysis is used to extract a human speech and translate into a sequence of sound elements for the sequence of vowels reproduction. Then, several phonemes detection methods including the direct cross-correlation analysis, the linear predictive coding (LPC) association, the partial correlation (PARCOR) coefficients analysis, and the formant frequencies comparison are applied to each sound element to give the corrected command for the talking robot to repeat the sound sequentially. Finally, experiments to compare these techniques and verify the working behavior of the robot are performed. The result of the tests indicates that the robot is able to repeat a sequence of vowels spoken by a human with a successful rate of more than 70% for the PARCOR analysis technique and the formant frequencies comparison technique. The greatest accuracy for repeating the sequence is given by the formant comparison method, while the direct cross-correlation method delivers the least accuracy.

In this paper an interpolation method based on quintic non-uniform rational B-spline(NURBS) is proposed to construct curves when to plan the trajectory of manipulators with respect to three objectives, time optimal, energy optimal and smoothness optimal. The mathematical model of quintic NURBS curve is set up to gain high-order continuous trajectories with endpoint configuration parameters can be specified, and a fast and elitist multi-objective genetic algorithm (NSGA-II) is adopted to optimize the trajectory of manipulators aims to get a series of Pareto optimal solutions under the three objectives. Through the simulation with six-degree of freedom robot shows that quintic NURBS curve can get high-order continuous trajectories and NSGA-II algorithm can provide an effective approach to get the perfect Pareto solutions for quintic NURBS curve. By constructing a average fuzzy membership function, a potential optimal solution can be selected from Pareto optimal set, then the high-order continuous optimal trajectory can be obtained.

With the rapid growth of the number of micro-blog, a lot of useless information flooded in the users vision, the users find it difficult to choose micro-blog recommendation service according to personal interest, so micro-blog filtering technology is applied to the micro-blog service. The interests of users change with the time, so the traditional batch learning can not be able to satisfy the need of users interest model. However, the machine learning which is based on online learning solved these problem in a certain way. The optimization of micro-blog filtering can decrease classification errors and improve the classification of data, but it has its own disadvantages. Although online support vector machine filtration is excellent, there's long-running shortcomings. The paper focus on the improvement of efficiency of the online support vector machine filtering by reducing the size of the training set, the number of training and the number of iterations. The experimental results show that the filtering performance fluctuate slightly, but it can almost be ignored because of the advantage of its efficiency, and the great amount of data is, the greater the efficiency becomes more obvious.

A 12-phase rectifier power generation system with a new type of topology and its rectifier-side short circuit fault are studied. The new type of system has four sets of rectifier devices with two series and two parallel and the traditional system has four sets of rectifier device with four parallels. The difference of DC voltage and DC current in normal operation and rectifier-side fault between them is analyzed. For the rectifier-side short circuit fault under no-load condition, the short circuit current expressions in AC side and DC side are derived, the novel rectifier power system simulation model is established in Matlab/Simulink software environment and rectifier-side short circuit fault simulation is performed. The simulation results accord with the derived expression of the short circuit current.

Wall robots must have adsorption and movement functions, and the safety of the adsorption system is a key index which determines the robot's performance. The redundant control theory was applied in the vacuum absorption system of wall cleaning robot, and its feasibility was analyzed, then a model was established. A redundant system of double vacuum bumps was put forward to enhance the robot's safety. It's proved theoretically that in the redundant system, the mean time between failures of the wall robot is extended. The experimental data shows that the redundant system is practicable and adjustable, and the two pumps can switch rapidly and stably.

This paper reports the first demonstration of a self-powered environmental monitoring robot which backpacked a biofuel cell (BFC) and a micro wireless sensor module on insect. Electric power was generated from blood sugar in its hemolymph by using the BFC and temperature and humidity around it was monitored by using the wireless sensor module. Furthermore, the robot moves autonomously by the intention of insect. First, the BFC which can be backpacked cockroaches was fabricated with a 3D printer. The electrochemical reaction of the anode in the insect-mountable BFC (imBFC) was evaluated and an oxidation current of 1.18 mA/cm2 (at +0.6 V vs. Ag|AgCl) was observed. Then, the performance of the imBFC was evaluated and a maximum power output of 333 μW (at 0.5 V) was obtained. Furthermore, a wireless temperature and humidity sensor was successfully driven by the imBFC. Finally, the imBFC and the micro wireless sensor module were mounted on the insect and environmental monitoring was done by the insect. These results indicate that the insect which backpacked the self-powered battery and micro wireless sensors has sufficient potential as microrobots for environmental monitoring and searching in disasters.

This paper presents an example of a PID controller applied to a 2-dimensional rotorcraft landing gear with two DOF (degrees of freedom), as well as the design of the landing gear dynamic model. The focus of this work is to maintain the landing spot to prevent the landing gear from skidding sideways on the ground, while adapting to different ground conditions. A nonlinear model for the landing gear dynamics formulated by solving Lagrange equation, is described in detailed, as well as the angle generation equations to provide reference signal to the system. The simulation results based on different surface conditions are presented.

Considering the original partial coherence method could be only applied to a single-response system, a weighted partial coherence method is proposed to analysis multi-responses systems. This article takes the emission noise of a hydraulic excavator as a test object, accomplishes its emission noise level evaluation and noise source identification. A multi-responses system has been analyzed by a quantifiable exterior noise contribution of multi-field points method, quantifying the contribution of different noise sources and determining the radiator fan as the main source of emission noise. An effective acoustic package solution has been made into practice according to the contribution results. The verifying test confirms that the hydraulic excavator reduces outside noise by 4.23dB (A).
