  • Soft Robot made of hydrogel and electroactive polymer, by Tiefeng Li(李铁风)

Abstract: The softness and large strain actuation of responsive hydrogels promise the potential to fabricate soft devices, which can function as a robotic system. The key challenges lie in the fabrication of soft devices with robust actuating ability and biocompatibility to the attached organ. Here we present a solution that integrates the responsive hydrogel membrane, electro-active polymer and flexible electronics can be integrated into a electromechanical device. As an example, the actuation assisting function of this soft device for shrinking an animal bladder is presented. The mechanical behaviors of the balloon-like soft device are experimentally and theoretically investigated. The concepts are applicable to other applications such as soft implants, soft robotics, and microfluidics.


  • Biologically Inspired Robots: Flying Like a Fly, Swimming Like a …. Fly?, by Pakpong Chirarattananon, Assistant Professor, Department of Biomedical Engineering City University of Hong Kong (Email: pakpong.c@cityu.edu.hk; Web: http://ris.mbe.cityu.edu.hk)

Abstract: Using only tiny nervous system, flying insects are able to perform superlative aerodynamic feats such as deftly avoiding a striking hand or landing on flowers buffeted by wind. These amazing creatures inspire scientists and engineers to understand and translate this ubiquitous form of locomotion into man-made machines. In this talk, I will discuss challenges that arise in the fabrication and control and exciting research outcomes related to millimeter-scale biologically-inspired flapping-wing robots. Challenges for the development of such small robots are associated to actuation, power and complex fluid-structure interactions. Through multiple iterations of designs, experiments and theoretical modeling, over the years, not only did we demonstrate a stable tethered flight of an insect-scale robot, but complex maneuvers have also been realized. The flapping-wing robot is capable of flying, landing on a wall, or swimming and transitioning out of the water.

Biography: Pakpong Chirarattananon received his Bachelor and Master degrees from University of Cambridge, UK, and a Ph.D. degree from Harvard University under the supervision of Professor Robert Wood in 2014. His graduate work was centred on the dynamics and control for insect-scale flapping-wing robots. In December 2014, he joined the Department of Mechanical and Biomedical Engineering as an Assistant Professor and founded the Robotic and Intelligent Systems Laboratory at City University of Hong Kong. Dr Chirarattananon is broadly interested in applying control and dynamic system theories to study aerial and biologically-inspired robotic systems. He has published in Science, Science Robotics, and has been nominated as the best student paper award finalist at the 2013 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) and the best paper award finalist at the 2014 IEEE International Conference on Biomedical Robotics and Biomechatronics. Dr Chirarattananon is serving as the publication co-chair for the upcoming 2019 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) and the 2019 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM).


  • Stochastic Hydrodynamic Model for Biogenic Mixing, by Zhi Lin 林智

Abstract: Biogenic mixing (the mixing and transport due to the swimming of marine species) has attracted a significant amount of interdisciplinary research efforts in recent years. In previous work, the applicant has contributed in deriving a stochastic hydrodynamic model that incorporates both deterministic fluid dynamics models and statistic description for stochastic swimming with a bottom-up approach and leads to a formula for the effective diffusivity. This model provides a new approach for the study of biogenic mixing and similar phenomena in other areas of science and engineering. Recently, we are seeking to improve the model and its simulation by considering various complicated factors, such as anisotropic swimming, nonlinear coupling by massive schooling.

  • 基于流动控制方程作为物理约束的三维实验数据后处理技术, by Qi Gao 高琪

Abstract: 近年来实验流体力学测量技术在很多方面有了显著的发展,实验能实现三维非定常复杂流动的多物理量耦合测量。而针对时间解析的三维实验数据处理和分析也出现一个让人眼前一亮的趋势,就是通过引入物理约束,或者说利用流动控制方程来优化实验结果、进行杂交的数值模拟计算和对流场的预测。这一发展方向上,最具代表性的就是通过时间解析的三维速度场来重构流场三维压力场的技术,通过不可压缩连续性方程来抑制速度场误差,通过压力梯度无旋方程来实现压力场误差的抑制,通过涡量方程来实现三维数据时空分辨率的提高,以及以实验数据作为流场初边值条件通过求解动量方程来实现流场整体的数据优化。本报告将针对实验数据后处理技术来介绍其发展的最新动向。


  • Living Cell based Modular Micro Robot Fabricated by Robotic Micro-Manipulation System, by Lianqing Liu 刘连庆 (Professor Shenyang Institute of Automation, Chinese Academy of Science, China)

Abstract: Micro-robots have a great application prospect in the biomedical field due to the feature of small size. To solve the issues of energy supply and bio-compatibility of micro-robots, the bio-syncretic micro-robots actuated by living cells have been studied widely. However, the fabrication, assembling and control of the bio-syncretic micro-robots are the main challenges for the development of the bio-syncretic micro-robots. In this talk, manufacture and control of the living cells based modular micro robots will be discussed. Firstly, a robotic micro-manipulation system will be introduced to implement the high-throughput fabrication of the biological modules of micro robots, and to execute the on-line flexible assembling of the bio-syncretic robots by the fabricated living cells based modules. Then, an approach based on circularly distributed multiple electrodes (CE) will be induced to improve the differentiation of myoblast cells and characterize the electro-responsive beating behavior of living myotubes for the development of bio-syncretic micro robots. Moreover, a biomimetic bio-syncretic crawler actuated by living myotubes was demonstrated to move under the control of the CE. This talk will not only be related to the micro-robots, but will be also informative for biological tissue engineering and drugs screening.

  • 仿生微型飞行器设计中的空气动力学机理及其应用, by Jianghao Wu 吴江浩

Abstract: 自然界中的昆虫和较小的鸟类展现出了卓越的机动飞行能力,这得益于其充分利用了翅膀拍动过程中产生的诸多非定常高升力气动原理。在仿生微小型飞行器上应用和融合这些高升力机理、实现高性能飞行是研究者们的梦想。近年来研究人员借鉴蜻蜓与蜂鸟等生物飞行的空气动力学原理提出了微型扑旋翼及仿蜂鸟扑翼两类代表性的仿生微型飞行器。其中,前者的翼主动竖直拍动、被动旋转,其翼的竖直拍动产生推力驱动翼旋转,借助拍动及旋转耦合效应使扑旋翼能够兼顾高升力产生及高气动效率;后者借鉴蜂鸟飞行原理实现仿生飞行及控制。本报告将介绍这两类仿生微型飞行器的空气动力学机理及其在气动增升、控制及飞行器总体设计等方面的应用进展。


  • Flow visualization and measurement via computer vision technologies, by Shengze Cai 蔡声泽

Abstract: Particle image velocimetry (PIV), as a flow visualization technology, can provide non-intrusive quantitative measurement of the velocity fields. This technique has been studied intensively and plays an increasingly important role in experimental fluid mechanics. To go deeper insight into complex flow phenomena, precise motion estimation methods dedicated to fluid mechanics and towards real-time measurement are being investigated in this talk. On the one hand, variational optical flow computation coupled with the stochastic transport theory is proposed for turbulent flow estimation. This formulation can extract accurate velocity fields from particle images as well as scalar images. On the other hand, deep learning technique is also introduced to PIV estimation with high efficiency, which is promising for real-time measurement and active flow control.
