Study on kinematic characteristics of SMA bionic flexible dexterous hand

Yang Xu Yanxiang Fu Yingqian Ni Xiangrui Yang Yikun Xiong

D-H parameter method is employed to conduct forward kinematic analysis of the dexterous hand in this article, in order to obtain the mechanical performance of the SMA biomimetic flexible dexterous hand for object grasping. The D-H parameters of the dexterous hand are determined, and the position expression of the fingertip relative to the base coordinate is obtained through theoretical calculations. Furthermore, inverse kinematic theoretical analysis of the biomimetic dexterous hand is conducted to obtain the joint angle parameters of each finger. A forward kinematic simulation model of the biomimetic dexterous hand is established, and the relationship between finger joint angles and fingertip position curves is obtained through simulation. The simulation results are compared with the theoretical analysis results to validate the correctness of the kinematic analysis of the dexterous hand, providing insights for its optimized design.

An improved device for the 3D optical scanner calibration and related influence factors on calibrating result

Yikun Xiong Jian Xu Sen Zhou Long Chen Jun Xiong

Nowadays, in industrial area, many mechanical part manufactures are applying 3D optical scanner in their production shop to do part online inspection, or in their coordinate measurement laboratory to obtain crucial part dimensions. The high demands of the 3D optical scanner make it necessary for researchers to create convenient and stable device for calibrating this kind of contact-less measurement instrument. In a former study, we introduced a plate with standard spheres as a calibration device, which showed a good test result when applied on a 3D optical scanner. However, we decide to do more research on related area. The first purpose of this paper is to present an improved calibration device based on our former study and daily work experience. The new device has a wider test range with less spheres, and it's structure is more portable, stable and more convenient to provide spatial positions. Results showed that the new device performed well in data stability and is quite easy to practice. The second purpose of this work is to study related influence factors on the 3D optical scanner calibration process. We investigated factors such as temperature, points cloud density, reflection patch density and numbers of images stitching. The results showed that those factors should be limited in proper conditions to ensure an acceptable calibration of 3D optical scanner.

Development of a calibration device for the optical scanner

Long Chen Yikun Xiong Sen Zhou Ying-Qian Ni Jun Xiong

A calibration device for the optical scanner is presented in this paper for the situation that lacking of a convenient calibration method for the optical scanner in domestic industry practice. The device utilized the spherical center distance of fixed balls as standard dimensions. It can provide various dimensions in different orientations and magnitudes since it has nine fixed standard balls in different positions. When we run an actual measurement process on this device with an optical scanner, the indication error of the scanner can be obtained conveniently. The device is simple in structure and easy to operate, it can produce multiple dates in one single measurement process simultaneously, which can evaluate the performance of the optical scanner comprehensively.

Performance evaluation experiments on scanning probe microscope

Sen Zhou Yikun Xiong Jin Zhou Tong Liu

Nowadays, with 3D topographic features increasingly complicated and complex, scanning probe microscopes have widely been used of nano-scale dimensional measurement in the semiconductor manufacturing and space industry, which can create three-dimensional data over almost all solids in a wide range of ambient. Although scanning probe microscopes readily achieve nanometer level resolution images of measured surfaces, there are several aspects of their behavior that can cause them to yield large measurement errors. In this paper, according to possible traceability pathways for calibration of lateral axes and z axis, both pitch and step height measurements are respectively performed and axis error self-correction model is proposed. The influence of thermal stability on drift error is also discussed. Experimental results show that our method will be helpful for a fast performance evaluation test for scanning probe microscope.
