Force measurement is important in the robotic manipulation tasks, and it is an essential property of specific tactile sensor. An increasing number of studies demonstrated the capacity of tactile sensor in force measurement. However, most of the works focus on the static force measurement, the precise track of dynamic force is hard to be accomplished. Compared with traditional piezoresistive sensors, piezoelectric-based tactile sensors have advantages in low energy consumption and high sensitivity. This paper developed a flexible multi-layer piezoelectric-based tactile sensor inspired by the structure of skin. The size of sensor with a 3×3 sensing element array was designed to match that of a finger. The signal processors and logical algorithms were integrated to sense and distinguish the size, location and pattern of different external force stimuli in real time, including pressure intensity and vibration frequency. Two experiments about pressure sensing and vibration sensing show that the proposed tactile sensor with finger-like force range, high sensitivity and fast response time. The range of measured force amplitude and frequency were 0.1N-2N and 0.1Hz-100Hz. Another characteristic, the response time, was less than 50ms. In addition, the sensor array has a spatial resolution of 4 mm. This work has driven the development of tactile sensor for dynamic force measurement in real-Time robotic grasping. © 2022 IEEE.

Aiming at rendezvous path planning of free floating space robot(the chaser satellite) in outer space, the path planning method to ensure safe approaching the non-cooperative space target based on the orbit mechanical equation is proposed. The whole rendezvous path planning strategy and safety principle of rendezvous path planning in ultimate approaching stage of free floating space robot are researched;Based on orbit mechanical equation, the moving ellipse locus of free floating space robot is generated using the safety principle to approach the non-cooperative space target in ultimate approaching stage. The method realizes that the space robot system approaches the spinning non-cooperative space target in free floating work mode, and the robot can escape safely when the subsequent work could not be normally completed. © 2012 IEEE.

As space antenna tends to be large-scale, deployable antenna is more and more widely used. As a key part of antenna structure, the antenna profile will be deformed due to uneven heating during on-orbit operation, which affects the service performance of the antenna. In this paper, the thermal effect mode of space environment on the on-orbit antenna is analyzed firstly, and the differential heat conduction equation is obtained by taking the profile as research object. Then, thermal simulation of the ring truss-type deployable antenna in the sun-synchronous orbit is carried out by using the NX-TMG software. The temperature characteristics of the antenna profile and the influence law of material parameters on the profile temperature during on-orbit operation are analyzed. It is concluded that temperature of antenna profile changes in one orbital period. The selection of low absorption rate and high density materials can reduce the profile temperature difference, which provides the reference for ring truss-type deployable antenna design. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

In this paper, a novel anti-swing controller is proposed for 3-dimensional (3-D) overhead cranes, which ensures fast transportation and efficient swing suppression during the regulation control process. Specifically, to increase the performance of the payload swing suppression, a swing-suppressing element is introduced, based on which a novel error signal is constructed. Then, a new control method is developed according to partial feedback linearization, and the overall system is divided into two subsystems including a defined error subsystem and a swing-suppressing subsystem. The stability analysis of the two subsystems and the overall system is given. Besides, the convergence of the system states is also proved. Simulation results are provided to demonstrate the effectiveness and superior performance of the proposed approach over the energy-based method. © 2014 American Automatic Control Council.

In this work, a standing wave acoustic field formed by using two contraposition transducers is used to classify the mixed powder. COMSOL-based simulations reveal the influence of the factors on the drop trajectories of the particles within an acoustic field. Then the experiments are carried out to demonstrate those obtained using COMSOL-based simulations. Finally, the separation experiments of the mixed powder of iron and dioxide silica are achieved, including the mixed powder both in the same diameter and the different diameter respectively. © 2020 Acoustical Society of America.

On the basis of only visual and odometer, a robust perception model is established to extract environmental features through effective fixed scale feature-transformation method, and updated feature by unscented Kalman filtering. The scale invariant feature transform (SIFT) is studied for 3D reconstruction, and a fast feature matching algorithm based on SIFT is proposed. A map representation method using SIFT features is also propounded, which is more convenient for environment recognition, robot localization and makes the data association map building much easier as well than the maps using simple features such as Harris corners and edges. The results of experiment show that this method can improve the success rate and precision of robot localization. © 2014 IEEE.

Small-angle x-ray scattering (SAXS) is an experimental biophysical method used for gaining insight into the structure of large biomolecular complexes. Under appropriate chemical conditions, the information obtained from a SAXS experiment can be equated to the pair distribution function, which is the distribution of distances between every pair of points in the complex. Here we develop a mathematical model to calculate the pair distribution function for a structure composed of several rigid components. We show that integrals of products of three spherical-Bessel functions arise naturally in this context. We then develop an algorithm for the efficient recursive computation of these integrals. Efficient and accurate models that relate the data acquisition process to the underlying structure are of interest because iterating such models provides a computational framework in which to solve the inverse problem of determining how constituent parts in a large structure should be assembled so as to be consistent with the experimental data.

In this paper, we propose a novel Bridge Weight-In-Motion (B-WIM) detection method based on the bridge deck vibration signal analysis with the image mapping algorithm. The algorithm maps the vibration signals into 8-Bit grayscale images and then uses image sharpness to detect B-WIM in single-vehicle tests. The result shows that the proposed method can effectively estimate B-WIM. © 2017 IEEE.
