| 1 | An overview of the configuration and manipulation of soft robotics for on-orbit servicing显示文摘Soft robots refer to robots that are softer and more flexible when compared with conventional rigidbodied robots. Soft robots are adapted to unstructured environments due to their flexibility, deformability and energy-absorbing properties. Thus, they have tremendous application prospects in on-orbit servicing(OOS).This study discusses the configuration and manipulation of soft robotics. Usually, learning from living beings is used to develop the configurations of most soft robots. In this study, typical soft robots are introduced based on what they mimic. The discussion of manipulation is divided into two parts, namely actuation and control.The study also involves describing and comparing several types of actuations. Studies on the control of soft robots are also reviewed. In this study, potential application of soft robotics for on-orbit servicing is analyzed.A hybrid configuration and manipulation of space soft robots for future research are proposed based on the current development of soft robotics, and some challenges are discussed. | Zhongliang JING Lingfeng QIAO Han PAN Yongsheng YANG Wujun CHEN | 2017 | Science China(Information Sciences)2017，60，5： | 8 |
| 2 | Wheat MADS-box gene TaSEP3-D1 negatively regulates heading date显示文摘The MADS-box gene plays an important role in regulating plant growth and development.In this study,a SEP3-like MADS-box gene TaSEP3-1 was isolated from bread wheat.The expression patterns of the three homoeologs TaSEP3-A1,TaSEP3-B1,and TaSEP3-D1 were similar,and higher expression levels were detected in floral organs and developing kernels.TaSEP3-D1 was located in the nucleus and cytoplasm and possessed transactivation activity in yeast.Homoeolog sequence polymorphism analysis identified four,three,and four haplotypes of TaSEP3-A1,TaSEP3-B1,and TaSEP3-D1,respectively,and the haplotypes of TaSEP3-D1 had larger effects on agronomic traits than those of TaSEP3-A1 and TaSEP3-B1.D1_h4,significantly associated with heading date,plant height,and other yield-related traits,was the favored haplotype of TaSEP3-D1.Transgenic wheat genotypes overexpressing TaSEP3-D1 exhibited delayed heading and reduced plant height,indicating a role in regulating heading date and plant development.These results shed light on the role of TaSEP3-D1 in wheat plant development.The favored haplotype of TaSEP3-D1 can be applied in breeding to improve plant architecture and yield in wheat. | Lei Zhang Hao Zhang Linyi Qiao Lingfeng Miao Dong Yan Pan Liu Guangyao Zhao Jizeng Jia Lifeng Gao | 2021 | The Crop Journal2021，9，5： | 2 |
| 3 | Targeted mutagenesis in Arabidopsis thaliana using CRISPR-Casi2b/C2ci^°°显示文摘Casi2b/C2ci is a newly identified class 2 CRISPR endonuclease that was recently engineered for targeted genome editing in mammals and rice.To explore the potential applications of the CRISPR-Casi2b system in the dicot Arabidopsis thaliana,we selected BvCasi2b and BhCasi2b v4 for analysis.We successfully used both endonucleases to induce mutations,perform multiplex genome editing,and create large deletions at multiple loci.No significant mutations were detected at potential off-target sites.Analysis of the insertion/deletion frequencies and patterns of mutants generated via targeted gene mutagenesis highlighted the potential utility of CRISPRCasi2b systems for genome editing in Arabidopsis. | Fan Wu Xinyu Qiao Yafei Zhao Ziyi Zhang Yifan Gao Lingfeng Shi Haokun Du Lulu Wang Ya-Jie Zhang Yu Zhang Langyu Liu Quan Wang Dejing Kong | 2020 | Journal of Integrative Plant Biology2020，62，11： | 1 |
| 4 | Distance-directed Target Searching for a Deep Visual Servo SMA Driven Soft Robot Using Reinforcement Learning显示文摘Performing complex tasks by soft robots in constrained environment remains an enormous challenge owing to the limitations of flexible mechanisms and control methods.In this paper,a novel biomimetic soft robot driven by Shape Memory Alloy(SMA)with light weight and multi-motion abilities is introduced.We adapt deep learning to perceive irregular targets in an unstructured environment.Aiming at the target searching task,an intelligent visual servo control algorithm based on Q-leaming is proposed to generate distance-directed end effector locomotion.In particular,a threshold reward system for the target searching task is proposed to enable a certain degree of tolerance for pointing errors.In addition,the angular velocity and working space of the end effector with load and without load based on the established coupling kinematic model are presented.Our framework enables the trained soft robot to take actions and perform target searching.Realistic experiments under different conditions demonstrate the convergence of the learning process and effectiveness of the proposed algorithm. | Wuji Liu Zhongliang Jing Han Pan Lingfeng Qiao Henry Leung Wujun Chen | 2020 | Journal of Bionic Engineering2020，17，6： | 0 |
