中文简介:
物理人机交互(pHRI)研究的最新进展原则上表明,人类和机器人可以主动、安全地共享一个共同的工作空间。使这些结果成为可能的根本突破是机器人力学和控制的以人为中心的设计。这使得限制意外接触造成的潜在伤害成为可能。以前的项目,特别是联合体一部分参与的PHRIENDS项目,在这些方面取得了显著的成果,构成了本提案的背景基础。受到这些结果的启发,SAPHARI将在机器人开发中进行一个根本性的范式转换,即我们将人类置于整个设计的中心。该项目将在以人为中心的路线图上迈出一大步,以一种紧密相连的方式解决人类与复杂的类人机器人系统之间安全、直观的物理交互的所有基本方面。该项目将围绕基于生物力学分析、人性化硬件设计和交互控制策略的安全问题,开发和验证关键感知和认知组件,使机器人能够实时跟踪、理解和预测弱结构动态环境中的人类运动。我们将为机器人配备对人类行为作出反应的能力,甚至在依赖于传感器的决策和背景知识的情况下主动进行交互。除了发展互动自主的必要能力,我们还将在认知层面紧密结合人类安全。这将使机器人能够以安全和自主的方式与人类进行反应或身体互动。考虑到“为安全而设计,为性能而控制”的模式,将从与机器人合作的人类的基本伤害机制开始,在几个领域进行研究发展。首先对刚性机器人进行分析,然后从安全性、能量和负载可持续性方面扩展到可变刚度驱动系统。生物力学知识和生物驱动的可变顺应执行器将被用于设计具有接近人类的设计特征和性能特性的双手操作系统。这种复杂系统的实时任务和运动规划需要新的概念,包括控制和规划的紧密耦合,从而产生新的反应行为。通过本体感知和外部感知信息的智能融合、基于传感器的任务规划、人类手势和动作识别与学习以及面向任务的编程(包括安全措施的配置与编程),将在大工作区移动操作场景中实现安全操作。最后,开发自解释交互和通信框架,增强系统的可用性,实现人机多模态无缝通信。该项目聚焦于两个工业用例,其中明确包含了人类和机器人协同工作人员之间经过深思熟虑的物理交互,以及医院中的专业服务场景,在该场景中,医务人员和辅助机器人在日常工作中紧密交互。这些典型的应用将为新市场和新兴市场铺平道路,不仅在工业和专业服务领域,还可能在家用机器人、先进的假肢和康复设备、远程操作和机器人手术领域。一般来说,这个项目的结果将强烈影响所有的应用程序,在这些应用程序中,交互式机器人可以帮助人类,并将他们从危险或常规任务中释放出来。
课程简介: Recent progress in physical Human‐Robot Interaction (pHRI) research showed in principle that human and robots can actively and safely share a common workspace. The fundamental breakthrough that enabled these results was the human-centered design of robot mechanics and control. This made it possible to limit potential injuries due to unintentional contacts. Previous projects, in particular the PHRIENDS project in which a part of the consortium has been involved, provided remarkable results in these directions, constituting the background foundation for this proposal. Inspired by these results, SAPHARI will perform a fundamental paradigm shift in robot development in the sense that we place the human at the centre of the entire design. The project will take a big step further along the human-centered roadmap by addressing all essential aspects of safe, intuitive physical interaction between humans and complex, human-like robotic systems in a strongly interconnected manner. While encompassing safety issues based on biomechanical analysis, human-friendly hardware design, and interaction control strategies, the project will develop and validate key perceptive and cognitive components that enable robots to track, understand and predict human motions in a weakly structured dynamic environment in real-time. We will equip robots with the capabilities to react to human actions or even take the initiative to interact in a situation‐dependent manner relying on sensor based decisions and background knowledge. Apart from developing the necessary capabilities for interactive autonomy, we will also tightly incorporate the human safety also at the cognitive level. This will enable the robots to react or physically interact with humans in a safe and autonomous way. Keeping in mind the paradigm to “design for safety and control for performance”, research developments will be pursued in several areas, starting with the fundamental injury mechanisms of humans cooperating with robots. The analysis will be first carried out for stiff robots and then extended to variable stiffness actuation systems in terms of safety, energy, and load sustainability. Biomechanical knowledge and biologically motivated variable compliance actuators will be used to design bimanual manipulation systems that have design characteristics and performance properties close to humans. Real-time task and motion planning of such complex systems requires new concepts including tight coupling of control and planning that lead to new reactive action generation behaviours. Safe operation will be enforced in mobile manipulation scenarios with large workspaces by smart fusion of proprioceptive and exteroceptive sensory information, sensor‐based task planning, human gestures and motion recognition and learning, and task‐oriented programming, including configuration and programming of safety measures. Finally, self explaining interaction and communication frameworks will be developed to enhance the system usability and make the multimodal communication between human and robot seamless. The project focuses on two industrial use cases that explicitly contain deliberate physical interaction between a human and a robot co‐worker, as well as on professional service scenarios in hospitals, in which medical staff and an assisting robot interact closely during daily work. These prototypical applications will pave the way towards new and emerging markets, not only in industry and professional services, but possibly also in household robots, advanced prostheses and rehabilitation devices, teleoperation, and robotic surgery. Generally, results of this project are expected to strongly impact all applications where interactive robots can assist humans and release them from dangerous or routine tasks.
