AbstractActuators of a robot that physically interacts with objects or human require backdrivability to obtain force controllability, impact resistance and compactness. An electro-hydrostatic actuator (EHA) is a servo pump type hydraulic system that has a potential to satisfy backdrivability. However, the previous mechanical design of a revolute EHA did not achieve compact design compared to the other actuators. The hydraulic pump and vane motor were separately located, which made the size of EHA system larger. To solve this problem, we propose a design methodology of a revolute EHA using a frameless motor. Commercially available frameless motor is suitable for actuating the hydraulic pump. Moreover, the pump can be built in the hollow space of the frameless motor, and this design makes the EHA downsized. We present a prototype design based on the formulation of the output power. Through the experimental validations, we show that developed EHA has higher backdrivability than the comparable harmonic drive, and obtain the knowledges on design factors that are crucial to the EHA with high power-to-weight ratio.Keywords: Electro-hydrostatic actuatorsbackdrivabilityinternal leakagemodularized design Disclosure statementNo potential conflict of interest was reported by the author(s).Notes1 http://store-en.tmotor.com/goods.php?id=8592 https://www.maxongroup.co.jp/maxon/view/content/ec-4pole-motors3 https://www.hds.co.jp/english/Additional informationFundingThis work was supported by the joint research of the University of Tokyo and Nachi-Fujikoshi CORP. titled ‘Research and development on the mechanism, control, and application of modular electro-hydrostatic actuators with high power-to-weight ratio’.Notes on contributorsMitsuo KomagataMitsuo Komagata received his BEng, MEng, and PhD degrees in Mechano-Informatics from the University of Tokyo in 2014, 2016, and 2020, respectively.

摘要与物体或人进行物理交互的机器人作动器要求具有反驾驶性,以获得力的可控性、抗冲击性和紧凑性。电静液致动器(EHA)是一种伺服泵型液压系统,具有满足反驱动性的潜力。然而,与其他致动器相比,以前的旋转EHA机械设计无法实现紧凑的设计。液压泵和叶片式马达分开布置,增大了EHA系统的尺寸。为了解决这个问题,我们提出了一种使用无框电机的旋转EHA的设计方法。市售的无框电机适用于驱动液压泵。此外,泵可以安装在无框架电机的中空空间中,这种设计使EHA体积减小。基于输出功率的公式,提出了一种原型设计。通过实验验证,我们发现开发的EHA具有比同类谐波驱动更高的反驱动性,并获得了设计高功率比EHA的关键因素。关键词:电液静压作动器;反驱动性;内部泄漏;注1 http://store-en.tmotor.com/goods.php?id=8592 https://www.maxongroup.co.jp/maxon/view/content/ec-4pole-motors3 https://www.hds.co.jp/english/Additional信息本工作由东京大学和Nachi-Fujikoshi CORP.联合研究“高功率重量比模块化电静压致动器的机理、控制和应用的研究与开发”提供支持。Komagata amitsuo Komagata分别于2014年、2016年和2020年获得东京大学机械信息学学士、学士和博士学位。2020年任东京大学项目研究员,2020 - 2023年任东京大学机械信息系项目助理教授。自2023年起,他在欧姆龙公司工作。他的研究兴趣包括驱动和机械设计。他是RSJ的成员。Takahiro Nakanishi,于2021年获得东京大学机械信息学硕士学位。主要研究方向为液压执行机构的机械设计。Ko Yamamoto于2009年获得日本东京大学机械信息学博士学位。他是东京大学机械信息系副教授。2009 - 2012年任东京工业大学博士后研究员,2012-2014年任名古屋大学助理教授。他于2014年加入东京大学,担任助理教授,2016-2017年担任机械工程系项目讲师。2012年,他还担任美国斯坦福大学客座助理教授。主要研究方向为类人机器人和软体机器人的机械设计、动力学计算与运动控制、基于人体肌肉骨骼模型的生物力学分析、群体机器人和步行人群的建模与控制。Yamamoto博士是日本机械工程师学会、日本机器人学会和IEEE的成员。中村义彦,日本京都大学机械工程专业博士。他是东京大学名誉教授和项目研究员,也是kinecopic, Inc.的联合创始人/首席执行官。在加入东京大学之前,他曾在京都大学和加州大学圣巴巴拉分校担任教职。他的研究领域是人形机器人,人类数字双胞胎及其计算算法。他获得了2019年JSME杰出工程师奖章,2021年IEEE机器人与自动化学会先锋奖,2022年Tateisi奖成就奖。Nakamura博士是塞尔维亚工程科学院外籍院士、慕尼黑工业大学特聘教授、IEEE终身会员、日本机械工程师学会会员;日本机器人学会;以及世界艺术与科学学院。

Social navigation framework for autonomous vehicle with hierarchical cyber-physical system architecture 具有层次网络物理系统架构的自动驾驶车辆社会导航框架

AbstractAn autonomous vehicle operating alongside humans should ideally have a high social capability, such as being able to communicate with humans, negotiate space, predict reactions, etc. This can be achieved by a prediction feature trained with diverse data on human behavior. Hierarchical cyber-physical system (CPS) architecture design, which sends the prediction feature to an external server while observing a limited operational design domain (ODD) and acquiring data continuously, has great potential to refine the training process as well as improve the performance. However, this architecture design requires the planning and prediction modules to be explicitly decoupled, which takes away from the recent success on social navigation. In this paper, we propose a novel autonomous navigation framework enabling social behavior while decoupling the planning and prediction modules to take advantage of the hierarchical CPS architecture. In the proposed framework, pedestrian trajectories are predicted as reactions to pre-generated candidates for an ego vehicle trajectory, and the ego vehicle trajectory is then selected to maximize mutual benefit to both the ego vehicle and surrounding pedestrians. We evaluated the proposed framework with simulations using the social force model and found that it was able to achieve the social behavior.KEYWORDS: Social navigationtrajectory planningcyber-physical systemarchitecture designsocial force model Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationNotes on contributorsYuto ImanishiYuto Imanishi received his MS degree from the Graduate School of Science and Engineering, Tokyo Institute of Technology, Japan, in 2009.

摘要与人类一起操作的自动驾驶汽车理想情况下应该具有较高的社交能力,例如能够与人类交流,协商空间,预测反应等。这可以通过用不同的人类行为数据训练的预测特征来实现。分层网络物理系统(CPS)架构设计在观察有限的操作设计域(ODD)并持续获取数据的同时,将预测特征发送到外部服务器,具有改进训练过程和提高性能的巨大潜力。然而,这种架构设计要求计划和预测模块显式地解耦,这与最近在社交导航上的成功有所不同。在本文中,我们提出了一种新的自主导航框架,支持社会行为,同时解耦规划和预测模块,以利用分层CPS架构。在提出的框架中,行人轨迹被预测为对预先生成的自我车辆轨迹候选者的反应,然后选择自我车辆轨迹以最大化自我车辆和周围行人的相互利益。我们使用社会力量模型对所提出的框架进行了模拟评估,发现它能够实现社会行为。关键词:社会导航轨迹规划网络物理系统架构设计社会力量模型披露声明作者未报告潜在利益冲突。yuto Imanishi于2009年获得日本东京工业大学科学与工程研究生院硕士学位。他目前是日本日立有限公司研发组的高级研究员。主要研究方向为自主控制、网络物理系统、建筑设计。他是SICE和JSAE的成员。Hiroyuki Yamada,分别于2008年和2021年在日本九州大学信息科学与电气工程研究生院获得硕士学位和博士学位。他目前是日本日立有限公司研发组的高级研究员。主要研究方向为机器人、计算机视觉、机器学习。他是RSJ和JSME的成员。

Hierarchical cyber-physical system (CPS) architecture design, which sends the prediction feature to an external server while observing a limited operational design domain (ODD) and acquiring data continuously, has great potential to refine the training process as well as improve the performance. However, this architecture design requires the planning and prediction modules to be explicitly decoupled, which takes away from the recent success on social navigation. In this paper, we propose a novel autonomous navigation framework enabling social behavior while decoupling the planning and prediction modules to take advantage of the hierarchical CPS architecture. In the proposed framework, pedestrian trajectories are predicted as reactions to pre-generated candidates for an ego vehicle trajectory, and the ego vehicle trajectory is then selected to maximize mutual benefit to both the ego vehicle and surrounding pedestrians. We evaluated the proposed framework with simulations using the social force model and found that it was able to achieve the social behavior.KEYWORDS: Social navigationtrajectory planningcyber-physical systemarchitecture designsocial force model Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationNotes on contributorsYuto ImanishiYuto Imanishi received his MS degree from the Graduate School of Science and Engineering, Tokyo Institute of Technology, Japan, in 2009.
