Neural networks modularity is a major challenge to study spiking pattern propagation and information processing in the brain. Sparse and heterogeneous connectivity between network modules defines spiking activity generation and interplay. Detailed study of modular network complex connectivity and dynamics is complicated by inducing retrograde or closed-loop activity. In this study, we analyzed the spiking activity of spontaneous and stimulus-induced interplay between two cultured neuronal networks (source-target) coupled with unidirectional synaptic connections, which were formed by microfluidic microchannels. Inhibition of excitatory synaptic activity in a source module abolished retrograde and closed-loop activity in the interplay. We found characteristics of electrical stimulation applied to the intermodular connections, which evoked a network-wide response in a target module. The developed approach can be applied to study synaptic plasticity in modular networks in vitro and improvement of new methods of neurointerface design. © 2021 IEEE.

In this study, we developed a new model of neuronal cells plating into a developed neural network to study functional integration using microfluidic methods. The integration was modeled in a three-chamber microfluidic chip by growing two weakly coupled neuronal networks and enhancing its connectivity by plating new dissociated cells. The direction of connections was formed by the asymmetric design of the chip. Such technology can be used to develop a new type of scaffold to recover the modular structure of the network. © 2021 Institute of Physics Publishing. All rights reserved.

IEEE/SICE International Symposium on System Integration

作者： R. Agarwal P. Sharma S. K. Saha T. Matsumaru Dept. of Mechanical Engineering IIT Delhi Hauz Khas New Delhi-110016 India Bio-Robotics and Human-Mechatronics Laboratory Graduate School of IPS Waseda University Kitakyushu Fukuoka Japan

ISBN: (纸本)9781509033300

This paper showcases the development of a mobile robot integrated with Projectable Interactive Surface to facilitate its interaction with human users. The system was designed to interact with users of any physical attributes such as height, arm span etc. without re-calibrating it. The system was designed in such a way that there would be no need for the human to come in physical contact with the robot to give it instructions. This system uses a projector to render a virtual display on the ground allowing us to project large displays. Microsoft Kinect integrated in the systems performs a dual functionality of tracking the user movements along with mapping the surrounding environment. The gestures of the tracked user are interpreted and an audio visual signal is projected by the robot in response.

The purpose of rotary series elastic actuators (RSEAs) is to reduce the interface stiffness between an actuator and the user, while achieving torque control, less inadvertent damage, high shock tolerance, and energy storage. In this paper we developed a RSEA test platform and control system for identifying the factors that affect performance. The effectiveness of a RSEA is studied by a sequence of experiments where a series of torque profiles are supplied to a handle, which the user holds while providing rotation about the elbow joint. By comparing desired torque outputs with those found via the spring deflection and those measured by an in-system load cell, the performance of the system is analyzed. The results indicated that the system is mostly limited by the torsion spring, its attachment, and the nonlinearities associated with it. The spring itself has a large impact on the torque/frequency bandwidth of the RSEA. © Springer-Verlag Berlin Heidelberg 2012.

This paper presents one of the interaction models between humans and machines using a camera, the projector, and the spot-light from a laser pointer device. A camera was attached on the top of the projector, and the projector directed a direction screen display on the wall, while the user pointed a laser pointer to the desired location on the direction screen display. It is confirmed that this system can handle some distortion conditions of the direction screen display, such as an oblique rectangle, horizontal trapezoid distortion, and vertical trapezoid distortion as well as some surface illuminance - 127, 425, 630, and 1100 lux;and the system is designed to be used for static and moving objects. The coordinates that were obtained from the distorted screen can be used to give commands to a specific machine, robot, and application.

The basic idea underlying this research is that the performances of wearable robots (WR) might be improved by optimizing the dynamics of the system comprised of the robot and the human body wearing it. This problem is not amenable to analytical investigations, and it asks for suitable numerical techniques able to simultaneously account for both robot mechanical structure dynamics and control laws. This paper presents on-going research efforts oriented to demonstrate a novel methodology for the design of an active lower limbs orthosis.

This paper introduces a tag-playing robot as a "Friendly Amusing Mobile" (FAM) function to expand the mobile robot Step-On Interface (SOI) use and to promote the human-robot interaction through a motion, targeting maintenance, training, and recovery of human physical and cognitive functions in the elderly, physically challenged, injured, etc. Displaying a previously prepared bitmap (BMP) image becomes the display update rate faster and makes it easy to design button placement and other screen parameters using a painting software package. The scope matrix generated from the BMP image simplifies the step detection and recognition, and the motion trajectory design editor facilitates the robot behavior design. © 2010 IEEE.

This video shows the basic functions of HFAMRO-2 equipped with the step-on interface (SOI). In the SOI the projected screen is used as a bilateral interface. It not only presents information from the equipment to the user but also delivers the instructions from the user to the equipment. HFAMRO is intended to represent the concept based on which robots interact with users. It assumes, for example, the ability to play `tag' - in this case, playing tag with light, similar to `shadow' tag. The HFAMRO-2 mobile robot, developed to study the SOI's application with mobility, has two sets of the SOI consisting of a projector and a range scanner on a mobile platform. The projector displays a direction screen on a travel surface and the two-dimensional range scanner detects and measures the user's stepping to specify the selected button.
