A novel underactuated manipulator possessing high self-adaptation ability is designed. The manipulator is highly underactuated as it contains several cable-bar units controlled by a single motor through a cable. The transfer matrix which reveals the correlation among cable tension force, joint frictional torques and grasping force is established by using vector mechanics and the principle of virtual work. Basing on the stiffness matrix which is established on basis of statics analysis, the influence of length ratio of cable-bar units on structural stiffness is discussed. The correctness of statics analysis is validated by simulating in ADAMS. Then, the dynamic model is established by using Lagrangian method. The correctness of dynamics analysis is validated by comparing calculation results and simulation results basing on the same grasping strategy.

This paper presents a novel hexapod robot with legs radially free distributed around the body. Compared with radial symmetric or rectangular symmetric robots, the legs of radially free distributed hexapod robot can rotate around the body of the robot and redistribute their positions thanks to the proposed radially free distribution mechanism. The kinematic model of the articulated leg mechanism is obtained to reveal the relationship between the body movement and the joints movement. The enlarged workspace shows the superiorities of leg distribution in the application of hexapod robot. Then an analysis on the stability of the robot is addressed to verify the effectiveness of proposed radially free distribution mechanism in theory.

In the paper, it is proposed that multi-spectral image pure pixel is utilized for completing SAM classification. The classified samples are utilized for electively constructing sparse dictionary, thereby improving the representativeness of the dictionary. Eight surface feature types are set in Landsat8 image. PPI index is used for calculating pure pixel index of each pixel. Pure pixel of each surface feature is further extracted through N-D visualizer, which is used for SAM calculation. Eight kinds of surface feature samples are selected from SAM image for online dictionary learning. Multi-spectral image sparse dictionary is generated. Multi-spectral image sparse coefficient is calculated through dictionary and OMP. Meanwhile, online dictionary and OMP are utilized for obtaining panchromatic image sparse coefficient. Fusion sparse coefficient is generated by maximum values both sparse coefficients. Multi-spectral image sparse dictionary is combined for reconstructing and generating fusion image. Eight quantitative fusion evaluation indicators are adopted for comparing algorithm fusion and weighted fusion in the paper. Fusion method proposed in the paper contains more information, fusion image texture detail information is improved, and better image multi-spectral information is kept.

This paper studies the optimization problem of agile-turn for the vertically launched missiles. The objective of this problem is to minimize the flight range. Compared with the previous studies, there are three major difficulties in solving this problem: (1) the problem is based on the six-degree-of-freedom dynamic model; (2) Due to the large angle attitude maneuvers, there exists singularity phenomenon of attitude in addition to the problem of strongly nonlinear coupling; (3) the missile adopts the integrated control system including thrust vector and tail fin controls, which causes that the nonlinear optimal control problem of the agile-turn is multiple-phased. The six-degree-of-freedom flight dynamics model of the missile is established in detail. Then the optimal control problem is solved by hp-adaptive Radau pseudospectral method. It is found that due to the disparity in the capability of attitude maneuvering, the missile uses the thrust vector control as the major mean to accomplish the agile-turn in the first flight phase. In the second flight phase, by operating the tail fins, the velocity and attitude of missile get stabilized and the terminal constraints are satisfied. The simulation results demonstrate the feasibility of agile-turn from vertical launch to attack ground targets, and the efficiency of the integrated control system.

A novel quadruped walking robot with four identical serial-parallel legs of four degrees of freedom was designed, which has both big workspace and high movement accuracy. Based on the hybrid leg of the quadruped walking robot, the trajectory planning of the foot end was carried out. According to the trajectory, the driving function of the motors was calculated by MATLAB and the kinematics simulation of the series-parallel leg was actualized by means of ADAMS. Compared with the trajectory of the function of trajectory planning, the kinematics simulation results were consistent with the trajectory planning. What's more, the experiment was implemented successfully on the prototype of the hybrid leg, and the result showed that the foot end could move along the given trajectory. The research result verified the rationality and feasibility of the novel Serial-parallel leg and also built the foundation for the following experiments, gait planning, motion control and the further optimization design of the leg mechanism of the hexapod robot.

Acoustoelasticity provides a significant method for testing the residual stress on the mechanical components. This leads to use the ultrasonic methods to detect residual stress. However, the influence on the detection precision resulted from the uneven thickness of tested components and the inaccurate stress coefficient obtained by the tensile experiment because of the tensile deformation. To address the difficulty in testing the residual stress distribution in the depth direction or the bolt axial direction, this study proposes a new method by combining ultrasonic shear and longitudinal waves based on acoustoelasticity theory. Meanwhile, the formulas also been provided. In addition, by the bolts which are made of austenitic stainless steel (A2-70), low-carbon steel (4.8) and carbon steel (8.8), a comparison of ultrasonic testing methods and tensile testing also has been given. In the end, the results show that the absolute error limit is 20MPa and the relative error of the testing method is less than 25%. Therefore, the new methods can be widely applied in the detection of the residual stress in the depth direction.

To research the influence of mechanical mechanism emerging in interaction manipulation aimed to quantitatively analyze and design force sensor on nonconductive micro object used to construct non-conductive device, mechanical theory modeling of micro glass sphere acting on the substrate was primarily established according to assumption conditions. On the basis of further analysis of interaction model, experimental procedures consisting of overall steps in transferring micro glass object using the manipulator ends, possessing two kinds of interactive manipulation of picking-up methods including interaction positions acting on the micro glass sphere and interaction angles formed by the central axial line of active end and substrate plane, were conducted to discuss the mechanical effect of interaction under the scanning electron microscope (SEM), respectively. Additionally, deviations of locations landed onto the substrate relative to the allowable presetting area were also considered. The experimental results demonstrated that the micro glass spheres were enabled to pickup with the interaction angle of about 30 degrees and interaction position located underneath the central plane of micro sphere, and realize the allowable manipulation of placement which may ask for strictly controlling time of transferring micro glass sphere within a shorter period of time.

As one of the most promising substitutes for regenerative medicine, the pore cell scaffold attracts great attentions in tissue engineering recently. In this study, we apply microfiber to assemble this kind of porous structure based on magnetically-guided manipulation. The microfiber is fabricated by biocompatible and biodegradable alginate solution inside a microfluidic device. To feasibly manipulate the microfiber, homogeneous magnetic nanoparticles are encapsulated into the alginate solution to improve controllability. Simultaneously, an external magnetic force generated by a round permanent magnet is provided to attract the microfibers on a magnetized device composed by pure iron wire arrays and wax. To provide a bionic environment, the magnetized device has been fabricated to allow the generation of optimal pore structure with submillimeter size and high density. As preliminary results, we have achieved to fabricate a one-layer cell scaffold through magnetically-guided micromanipulation.

Surface defect analysis of rotary metal parts is a requirement to research quality and operating state of parts. This paper proposes a new approach and algorithms for surface defect analysis of rotary metal parts. Given the captured surface images as an input, the approach first uses the pose relation of the mechanism and a simple weighted average algorithm to obtain one seamless large image by fast stitching of the measured multi-view images. Then, to perform initial segmentation of surface defects, the possible defects are segmented using the developed segmentation algorithm based on contourlet transform with adaptive thresholds (CTAT) and the improved active contour model (ACM), and the defect parameters can be obtained and evaluated. Experimental results on inspection of the surface defects for a variety of rotary metal parts are reported to show the validity of the proposed methodology.
