This paper utilizes a road network robotic system called a ‘Traffic Control Signal’ (TCS). The TCS uses a variety of active sensing (‘active perception of motion’ (APMs)) but the focus will only be on pavement bicycle inductance loops. This leads to an entanglement of functionality of signal processing for motion control of Humans-to-robotic to power recharging, and enhance communications for people with vision and hearing impairments for wayfinding. Inductance loop development is likely to be driven by increasing community expectations for inclusive sustainable technologies with low whole of life costs. Secondly, to improve communications between Human-to- machines-to-entities to achieve an inclusive ‘Internet of Things’ (IOT) ecosystem. In this paper, the focus is on existing technologies (‘off-the-self’ [OTS]) that may be re-engineered and then re-purposed. The context relates to in-pavement loops as an enabler to the development of Bio-communications between machines-to-entities for ‘Internet of Things’ (IOT) motion control. Existing technologies may be able to be re-purposed and reused as ‘off-the-self’ (OTS) technologies to achieve future needs (must have) and wants (like to have) of Human-to-robot interaction. The outcome desired is a visualisation method to map the surface pattering of the unique active sensing (‘active perception of motion’ (APMs)) and then mitigate any constraints that limit an inclusive ‘Internet of Things’ (IOT) ecosystem.
本文采用了一种名为“交通控制信号”(TCS)的道路网络机器人系统。TCS使用多种主动感应(“主动运动感知”(APMs)),但重点只放在人行道自行车的电感环路上。这导致了人类对机器人运动控制的信号处理功能的纠缠,以充电,并加强视力和听力障碍人士的寻路沟通。电感回路的发展很可能受到社区对具有低全寿命成本的包容性可持续技术日益增长的期望的推动。其次,改善人-机器-实体之间的通信,实现包容性的“物联网”(IOT)生态系统。在本文中,重点是现有的技术(“脱自我”[OTS]),这些技术可以被重新设计,然后重新利用。背景涉及到路面内环路,作为“物联网”(IOT)运动控制中机器对实体之间生物通信发展的推动者。现有技术可以作为“脱自我”(OTS)技术被重新利用和重用,以实现未来人机交互的需求(必须拥有)和愿望(喜欢拥有)。期望的结果是一种可视化方法,用于绘制独特主动感知(“主动运动感知”(APMs))的表面图案,然后减轻限制包容性“物联网”(IOT)生态系统的任何约束。

In this paper, the effect of sterilization on a thin suture thread is evaluated, and verification of a developed testing machine is conducted. The suture threads for microsurgery is thin and easy to rupture. That will lead a medical accident, so that the evaluation of the thread's performance is important. One of the factors which decides the performance of the thread is sterilization. The thread must be sterilized for being utilized in a medical operation, and generally it deteriorates the performance of the thread. Tension and elongation of sterilized threads and non-sterilized threads are measured, and the difference among them is discussed. The measurement of the threads is conducted by using a developed testing machine. Reaction force observer (RFOB) is implemented in the machine to measure tension and elongation of the thread at the same time. Also, tension control is implemented to pull the thread from both sides that is similar to the operation which surgeons do. The validity of the testing machine is confirmed through the measurement.
本文评价了灭菌对细缝合线的影响,并对研制的试验机进行了验证。显微手术用缝线细,易断裂。这将导致医疗事故,因此对螺纹性能的评估很重要。决定螺纹性能的因素之一是灭菌。在医疗手术中使用的螺纹必须经过消毒,通常这会使螺纹的性能恶化。测定了灭菌螺纹和未灭菌螺纹的张力和伸长率,讨论了灭菌螺纹和未灭菌螺纹的区别。螺纹的测量是用研制的试验机进行的。机器采用反作用力观测器(RFOB),同时测量螺纹的张力和伸长。同时,通过张力控制将线从两侧拉出,这类似于外科医生所做的手术。通过测量,验证了试验机的有效性。

This paper compares performance of a double feedforward control system that considers for time delay. Recently, digital content size continues to increase. In order to cope, manufacturers of digital storage media try to increase capacity by narrowing the track pitch of these digital storage media. This digital controller designs and implements in a Field-Programmable Gate Array (FPGA). However, the control system includes non-integer the time delay. The time delay element exists in its characteristic polynomial. Therefore, the system is possibly destabilized by time delay. In the feedforward system, the feedforward compensation value is delayed by time delay. Considering these factors, a high-precision pickup control system that considering time delay is needed for optical discs. This paper proposes a new double feedforward control system considering time delay. In this paper, the tracking performance of the control system is compared to the conventional feedback control system and the new error based communication disturbance observer. In optical disc systems, the proposed double feedforward control system considering time delay has a good performance.
本文比较了考虑时滞的双前馈控制系统的性能。最近,数字内容的规模不断增加。为了应对这种情况,数字存储媒体的制造商试图通过缩小这些数字存储媒体的磁道间距来增加容量。该数字控制器是在现场可编程门阵列(FPGA)上设计和实现的。然而,控制系统包含非整数时滞。时滞元存在于它的特征多项式中。因此,系统有可能因时滞而失稳。在前馈系统中,前馈补偿值被延时延时。考虑到这些因素,需要一种考虑延时的高精度光盘拾取控制系统。本文提出了一种新的考虑时滞的双前馈控制系统。将控制系统的跟踪性能与传统的反馈控制系统和基于误差的通信干扰观测器进行了比较。在光盘系统中,考虑时延的双前馈控制系统具有良好的性能。

This paper proposes a design method of multilateral system based on reachability matrix for independent operation. A multilateral system is a one of the haptic transmission control, which is extended structure of bilateral control. If the multilateral system consists of many master system and one slave system, many human can obtain the haptic information of an environment through a slave system. However, a conventional multilateral system is that independent operation of master system is difficult because of same response of all master system. Therefore, the proposed method is focused on direct and indirect connection of subsystem. Specifically, design of subsystem connection which is satisfied desired performance is based on a reachability matrix and a digraph is derived by the reachability matrix. This research aims to construct multilateral system realizing independent operation and to transmit a haptic information from slave system. By using proposed method, the desired multilateral control that many human can operate independently can be realized. The validity of the proposed method is confirmed through the experiments.
提出了一种基于可达性矩阵的多边系统独立运行设计方法。多边系统是触觉传递控制的一种,是双边控制的扩展结构。如果多边系统由多个主系统和一个从系统组成,则许多人可以通过一个从系统获得环境的触觉信息。然而,在传统的多边系统中,由于各主系统的反应相同,主系统难以独立运行。因此,本文提出的方法侧重于子系统的直接连接和间接连接。具体来说,基于可达性矩阵设计满足预期性能的子系统连接,并由可达性矩阵导出有向图。本研究旨在构建独立运行的多边系统,并从奴隶系统传输触觉信息。采用该方法,可实现多人独立操作的多边控制。通过实验验证了该方法的有效性。

This paper proposes the robust H2 controller with constraints for the active suspension using the half car model. The purpose of this study is to improve the ride comfort with satisfying the structural constraints. According to International Organization for Standardization 2631, there exist the uncomfortable frequency bands of the human body. The uncomfortable frequency bands are 4–8[Hz] for the vertical acceleration and 0.63–0.8[Hz] for the pitch angular acceleration. In this paper, the acceleration in the specific frequency bands is suppressed by using frequency shaping. On the other hand, the active suspension has the structural constraints which are constraints on the vertical force of the wheel, the suspension stroke, and the control input. They are expressed as the time-domain constraints. In addition, the robust stability for the perturbation of the front and rear weights of the car body is guaranteed. The perturbation of the weights of the car body affects the pitch motion of the car body and the vertical force of the wheels. The robust stability for the perturbation is guaranteed by using the polytopic representation. The robust H2 controller is designed by solving a finite set of LMIs to achieve the purposes. The effectiveness of proposed controller is evaluated by simulations and experiments.
本文利用半车模型,提出了带约束的主动悬架鲁棒H2控制器。本研究的目的是在满足结构约束的前提下,提高车辆的乘坐舒适性。根据国际标准化组织2631的规定,存在对人体不舒服的频段。垂直加速度的不适频段为4-8 [Hz],俯仰角加速度的不适频段为0.63-0.8 [Hz]。本文采用频率整形的方法抑制了特定频段内的加速度。另一方面,主动悬架具有结构约束,包括对车轮垂直力、悬架行程和控制输入的约束。它们被表示为时域约束。此外,还保证了车身前后重量扰动的鲁棒稳定性。车体重量的摄动会影响车体的俯仰运动和车轮的垂直力。利用多面体表示保证了扰动的鲁棒稳定性。通过求解有限lmi集,设计鲁棒H2控制器。通过仿真和实验验证了所提控制器的有效性。

High-order disturbance estimation using Kalman filter for precise reaction-torque control 基于卡尔曼滤波的高阶扰动估计精确控制
Pub Date : 2016-04-22 DOI: 10.1109/AMC.2016.7496331
Yuki Nagatsu, S. Katsura
This research proposed a high-order disturbance estimation using Kalman filter for precise reaction-torque control. The proposed method is able to realize the reaction torque control system by using the proportional-derivative controller. It is confirmed that the proposed proportional-derivative controller of reaction torque can improve control system performance without enhancing the noise effect. This is because estimated variables by the proposed Kalman filter based high order disturbance/reaction torque observer are utilized in the PD controller. The observer can estimate the disturbance/external torque and its time derivative with lower noise level than the conventional disturbance observers (DOBs) or reaction torque observers (RTOBs). Experimental results validate the proposed method.

Soft-robotic structures and their materials are typically chosen according to a biological example. Medical imaging has been used to obtain 3D models of biological structures to create moulds for production of artificial, soft robotic counterparts. However, it is not enough to simply copy the geometry of these organisms; robots must be able to be modeled, and controlled, such that they can perform meaningful tasks. This involves investigating the robot's capability after it has been manufactured. The similarities between the biological and artificial robotic materials allow us to use methods from medical imaging in soft robotics. This paper proposes the use of medical imaging and alternative medical investigation methods for the static and dynamic characterization of soft robots and involves two soft-robotic case studies: a peristaltic pump (swallowing robot), and a peristaltic table. Articulography and manometry are shown to be useful techniques for investigation of the peristaltic pumping robot, and visual 3D scanning is demonstrated for the peristaltic table. Alternative medical investigation methods such as magnetic resonance imaging, computed tomography, and ultrasound are considered as other possibilities that require further investigation.
软体机器人的结构和材料通常是根据生物学的例子来选择的。医学成像已被用于获得生物结构的3D模型,以创建生产人工软体机器人的模具。然而,仅仅复制这些生物的几何形状是不够的;机器人必须能够被建模和控制,这样它们才能执行有意义的任务。这包括在机器人被制造出来后对其能力进行调查。生物和人工机器人材料之间的相似性使我们能够在软机器人中使用医学成像的方法。本文提出使用医学成像和替代医学调查方法对软机器人进行静态和动态表征,并涉及两个软机器人案例研究:蠕动泵(吞咽机器人)和蠕动桌。关节术和测压术被证明是研究蠕动泵机器人的有用技术,并展示了蠕动工作台的视觉三维扫描。磁共振成像、计算机断层扫描和超声波等替代医学调查方法被认为是需要进一步调查的其他可能性。

The objective of this paper is to design and implement a process about reverse engineering, which will generate smooth trajectories without using a high cost controller. Because contour of work pieces is more complex today, the trajectory planning and generation are essential in the whole process. In this paper, using Bezier curve to clarify the rough outline makes the process of reverse engineering more accurate and clearer. The pros and cons of Bezier curve and the comparison between Bezier curve and NURBS are mentioned. Additionally, we implement this system without a high level expensive controller, and to solve the complex curve problems efficiently and economically. We implement this system with Dual Drive Machine that is designed and implemented in our lab previously. Experimental results have been successfully conducted to prove the principle as proposed.
本文的目标是设计和实现一个关于逆向工程的过程,该过程将在不使用高成本控制器的情况下生成光滑的轨迹。由于工件的轮廓越来越复杂,轨迹的规划和生成在整个加工过程中至关重要。在本文中,利用Bezier曲线来厘清粗糙的轮廓,使逆向工程的过程更加精确和清晰。介绍了Bezier曲线的优缺点,以及Bezier曲线与NURBS的比较。此外,该系统的实现无需高级昂贵的控制器,可以高效经济地解决复杂的曲线问题。本系统采用本实验室先前设计和实现的双驱动机床来实现。实验结果成功地证明了所提出的原理。

In this paper, a concept design for a robotic exoskeleton for the neurological rehabilitation of temporomandibular disorder (TMD) is presented. The proposed system presents a lightweight, portable solution aimed at promoting user engagement in the rehabilitation process. A literature review into temporomandibular joint (TMJ) disorders and existing therapeutic devices has been undertaken, characterizing the problems experienced by patients and the solutions offered by current medical devices. Gaps in existing research have been identified and the study's findings used to determine the objectives of the design. The robotic exoskeleton provides a method of delivering assisted therapy to a range of TMD sufferers, incorporating visual feedback into therapy routines to promote active participation. Mechatronic design and development into both actuation and motion control of the proposed system has been conducted, arriving at a final solution that meets the needs of both the patient and the medical community.
