Rehabilitation Robotics and Translational Biomedical-Engineering Ushers in the Aging Society

9:50〜10:40, March 9th, 2017 @Collaboration Complex, Keio Univ.

Robotic therapy is a flagship example of the benefits of human-robot collaboration. However, the 2010 and the 2016 American Heart Association guidelines for stroke care endorsed robotic therapy for the upper extremity (UE), but not for the lower extremity (LE). In 2010, the US Veterans Administration similarly endorsed robotic therapy for UE, but not for LE: "recommendation is made against routinely providing the [LE] intervention… At least fair evidence was found that the intervention is ineffective …". This apparent immaturity of LE robotic therapy reflects the fact that, to date, knowledge of human motor control has not been applied to LE robotic therapy. The present talk aims to address that problem. Knowledge of human sensorimotor control has matured to the point where a fundamental theory of walking is within reach. To enable the application of robotics to assist walking, we propose a competent model of human walking. By "competent model" we mean that it may only be a first approximation of a fundamental theory, but it is good enough to improve the design of robots and regimens for LE therapy. We will conclude with an application example demonstrating the concept.

Recent Advancements in FPGA-based Controllers for Embedded Power Systems

10:50〜11:40, March 9th, 2017 @Collaboration Complex, Keio Univ.

Since their creation thirty years ago, Field Programmable Gate Array (FPGA) components allow designers creating specific hardware architectures that, most of the time, exceed the timing performances of their software counterparts. Of course this approach is also suffering from several pitfalls like more important power consumption or, at least up to now, a more difficult programming than standard microcontrollers. Recent technological trends tend to alleviate these limitations, proposing very powerful FPGA-based System-on-Chips. The purpose of this keynote is to present and discuss the recent trends in terms of FPGA-based industrial controllers. To this purpose, a special focus will be given on embedded power systems which represent a very important field of application which includes among others the more electric vehicles, the more electric aircrafts, the new distributed power generation systems… The presentation will be illustrated by many practical implementations. Specifically, the proposed keynote will cover the following points:

  • • Introduction

From Robotizing Humans' to Humanizing Robots

11:40〜12:30, March 9th, 2017 @Collaboration Complex, Keio Univ.

My talk first recalls some historical facts and key milestones of the robotic technology by underlining parallelisms and similarities of its evolutions with respect to that of the computers and computer science. I will show and explain the reasons on how and why robotic systems requirements have centered progressively toward human when robotics left progressively the automation field to invade services in various domains. This spreading of the robotic technology gave rise to novel challenging requirements in robotics design and usage that resulted in a deep renewal or robotic systems and impacted on various future societal and economical aspects. Robots are now being democratized and envisioned to not only substantially invade and improve classical service applications, but also be personal home assistants for frail persons. Paradoxically, human-centric robotics is entering back to the automation field renewing the vision of automation and assemblies together with practices of robots at work in various industries. On the more philosophical view, human-centered robotics concerns also the underlying question of “human augmentation”. The latter can be thought as related to a new robotic taxonomy that I define through a human-robot “distance” metric. Some conventional wisdom concerning robotic embodiment and the limitation of mind-controlled robotics systems will be discussed.

System Design Based on Wave Modeling and Reflected-Wave-Rejection

9:30〜10:20, March 10th, 2017 @Collaboration Complex, Keio Univ.

In order to realize rapid and accurate motion of machines and robots, vibration suppression of mechanical resonance is needed to be considered in control-system design. In the design, not only control law but also model of the mechanical resonant system is important. A two-mass resonant system is a simplest model and we can derive the simple controller by using the model. Although the controller can suppress the first-order resonance, it sometimes induces high-order vibrations, which is well-known as spillover problem. If a multi-mass resonant system is used as model of the resonant systems, we can obtain the controller for suppressing the high-order vibrations, but the control system becomes complex structure depending on the order of the model. As mentioned in the above, there is a tradeoff between suppression performance of high-order vibration and simplicity of the control structure.
To tackle the problem, this research proposes control system design based on wave modeling and reflected-wave-rejection control. In this research, a resonant system is modeled as wave equation which is one of a distributed parameter model. Additionally, based on a concept of wave transmission, a reflected wave rejection control is proposed to suppress the vibrations. The reflected wave rejection control has not only suppression performance of high-order vibrations but also a simple control structure which is composed of time-delay elements. The validity of the proposed method is verified by the simulation and experimental results.

Suspended Microchannel Resonators (SMR) for metrology of liquids, cells and nanoparticles

10:20〜11:10, March 10th, 2017 @Collaboration Complex, Keio Univ.

The advances in micro- and nanofabrication technologies enable the preparation of increasingly smaller mechanical transducers capable of detecting the forces, motion, mechanical properties and masses[1] that emerge in biomolecular interactions, fundamental biological processes, or in interaction with nano-objects. These nanomechanical systems have gained considerable relevance in the last decade, and are promising techniques for medical diagnosis, pharmacological research and environmental monitoring issues, because of their small size, high sensitivity and suitability for integration into miniaturized analytical systems and metrology equipment. Hence, they are relevant alternative to classical characterization techniques (Dynamic Light Scattering, flow cytometry) for cells and particles metrology in fluid, with applications in pharmaceutical, biological and environmental fields.
One of the most promising emerging nanotechnology-related approaches is based on micro- nanofluidic channel enclosed in a MEMS resonator, similarly to what is developed in MIT[2] and LETI[3] laboratories. This technology, known as Suspended Microchannel Resonator (SMR), has the ability to detect and accurately count particles, as small as 50nm, and reliably measure their buoyant mass (resolution down to the ag[4]), and size. Since this concept is based on Archimedes’ principle, it can also discriminate solid particles and lighter “nano-objects” like nanobubbles. In this presentation, I will detail current development related to this new sensor paradigm, with performances amenable to detect nanoparticles from a few nm in diameter up to the micro-scale[5]-[6], monitor cells growth rate for assessment of cellular responses to antibiotics and antimicrobial peptides[7] , and give our perspectives for future developments.
