Recent advances in upper limb prostheses have led to significant improvements in the number of movements provided by the robotic limb. However, the method for controlling multiple degrees of freedom via user-generated signals remains challenging. To address this issue, various machine learning controllers have been developed to better predict movement intent. As these controllers become more intelligent and take on more autonomy in the system, the traditional approach of representing the human-machine interface as a human controlling a tool becomes limiting. One possible approach to improve the understanding of these interfaces is to model them as collaborative, multi-agent systems through the lens of joint action. The field of joint action has been commonly applied to two human partners who are trying to work jointly together to achieve a task, such as singing or moving a table together, by effecting coordinated change in their shared environment. In this work, we compare different prosthesis controllers (proportional electromyography with sequential switching, pattern recognition, and adaptive switching) in terms of how they present the hallmarks of joint action. The results of the comparison lead to a new perspective for understanding how existing myoelectric systems relate to each other, along with recommendations for how to improve these systems by increasing the collaborative communication between each partner.

本文对人机对象切换的文献进行了调查。切换是一种协作的关节动作，其中代理人，给予者，给予对象给另一代理，接收器。当接收器首先与给予者持有的对象并结束时，当给予者完全将物体释放到接收器时，物理交换开始。然而，重要的认知和物理过程在物理交换之前开始，包括在交换的位置和时间内启动隐含协议。从这个角度来看，我们将审核构成了上述事件界定的两个主要阶段：1）预切换阶段和2）物理交流。我们专注于两位演员（Giver和Receiver）的分析，并报告机器人推动者（机器人到人类切换）和机器人接收器（人到机器人切换）的状态。我们举报了常用于评估互动的全面的定性和定量度量列表。虽然将我们的认知水平（例如，预测，感知，运动规划，学习）和物理水平（例如，运动，抓握，抓取释放）的审查重点，但我们简要讨论了安全的概念，社会背景，和人体工程学。我们将在人对人物助手中显示的行为与机器人助手的最新进行比较，并确定机器人助剂的主要改善领域，以达到与人类相互作用相当的性能。最后，我们提出了一种应使用的最小度量标准，以便在方法之间进行公平比较。

外骨骼和矫形器是可穿戴移动系统，为用户提供机械益处。尽管在过去几十年中有重大改进，但该技术不会完全成熟，以便采用剧烈和非编程任务。为了适应这种功能不全，需要分析和改进该技术的不同方面。许多研究一直在努力解决外骨骼的某些方面，例如，机构设计，意向预测和控制方案。但是，大多数作品都专注于设计或应用的特定元素，而无需提供全面的审查框架。本研究旨在分析和调查为改进和广泛采用这项技术的贡献方面。为了解决此问题，在引入辅助设备和外骨骼后，将从物理人员 - 机器人接口（HRI）的角度来研究主要的设计标准。通过概述不同类别的已知辅助设备的几个例子，将进一步开发该研究。为了建立智能HRI策略并为用户提供直观的控制，将研究认知HRI。将审查这种策略的各种方法，并提出了意图预测的模型。该模型用于从单个电拍摄（EMG）通道输入的栅极相位。建模结果显示出低功耗辅助设备中单通道输入的潜在使用。此外，所提出的模型可以在具有复杂控制策略的设备中提供冗余。

在本文中，我们在人工代理中介绍了活跃的自我的计算建模叙述。特别是，我们专注于代理人如何配备控制意识以及它在自主位于行动中的方式以及反过来，影响行动控制。我们认为这需要铺设一个体现的认知模型，将自下而上的过程（传感器学习和对控制的细粒度适应）与自上而下的过程（战略选择和决策的认知过程）。我们基于预测处理和自由能量最小化的原理提出了这种概念计算架构。使用此常规模型，我们描述了控制层次结构的级别的控制感以及如何支持在不可预测的环境中的动作控制。我们在模型的实施以及模拟任务场景中的第一评估，其中自主代理必须应对不可预测的情况并经历相应的控制感。我们探讨了不同的型号参数设置，导致不同方式结合低电平和高级动作控制。结果表明，在低/高级动作控制需求的情况下适当加权信息的重要性，并且他们证明了控制的感觉如何促进这一点。

我们描述了更改 - 联系机器人操作任务的框架，要求机器人与对象和表面打破触点。这种任务的不连续交互动态使得难以构建和使用单个动力学模型或控制策略，并且接触变化期间动态的高度非线性性质可能对机器人和物体造成损害。我们提出了一种自适应控制框架，使机器人能够逐步学习以预测更改联系人任务中的接触变化，从而了解了碎片连续系统的交互动态，并使用任务空间可变阻抗控制器提供平滑且精确的轨迹跟踪。我们通过实验比较我们框架的表现，以确定所需的代表性控制方法，以确定我们框架的自适应控制和增量学习组件需要在变化 - 联系机器人操纵任务中存在不连续动态的平稳控制。

可接受的是指对象允许的可能动作的感知。尽管其与人计算机相互作用有关，但没有现有理论解释了支撑无力形成的机制;也就是说，通过交互发现和适应的充分性。基于认知科学的加固学习理论，提出了一种综合性的无力形成理论。关键假设是用户学习在存在增强信号（成功/故障）时将有前途的电机动作与经验相关联。他们还学会分类行动（例如，“旋转”拨号），使他们能够命名和理由的能力。在遇到新颖的小部件时，他们概括这些行动的能力决定了他们感受到的能力。我们在虚拟机器人模型中实现了这个理论，它展示了在交互式小部件任务中的人性化适应性。虽然其预测与人类数据的趋势对齐，但人类能够更快地适应能力，表明存在额外机制。

Humans and animals excel in combining information from multiple sensory modalities, controlling their complex bodies, adapting to growth, failures, or using tools. These capabilities are also highly desirable in robots. They are displayed by machines to some extent - yet, as is so often the case, the artificial creatures are lagging behind. The key foundation is an internal representation of the body that the agent - human, animal, or robot - has developed. In the biological realm, evidence has been accumulated by diverse disciplines giving rise to the concepts of body image, body schema, and others. In robotics, a model of the robot is an indispensable component that enables to control the machine. In this article I compare the character of body representations in biology with their robotic counterparts and relate that to the differences in performance that we observe. I put forth a number of axes regarding the nature of such body models: fixed vs. plastic, amodal vs. modal, explicit vs. implicit, serial vs. parallel, modular vs. holistic, and centralized vs. distributed. An interesting trend emerges: on many of the axes, there is a sequence from robot body models, over body image, body schema, to the body representation in lower animals like the octopus. In some sense, robots have a lot in common with Ian Waterman - "the man who lost his body" - in that they rely on an explicit, veridical body model (body image taken to the extreme) and lack any implicit, multimodal representation (like the body schema) of their bodies. I will then detail how robots can inform the biological sciences dealing with body representations and finally, I will study which of the features of the "body in the brain" should be transferred to robots, giving rise to more adaptive and resilient, self-calibrating machines.

在本次调查中，我们介绍了执行需要不同于环境的操作任务的机器人的当前状态，使得机器人必须隐含地或明确地控制与环境的接触力来完成任务。机器人可以执行越来越多的人体操作任务，并且在1）主题上具有越来越多的出版物，其执行始终需要联系的任务，并且通过利用完美的任务来减轻环境来缓解不确定性信息，可以在没有联系的情况下进行。最近的趋势已经看到机器人在留下的人类留给人类，例如按摩，以及诸如PEG孔的经典任务中，对其他类似任务的概率更有效，更好的误差容忍以及更快的规划或学习任务。因此，在本调查中，我们涵盖了执行此类任务的机器人的当前阶段，从调查开始所有不同的联系方式机器人可以执行，观察这些任务是如何控制和表示的，并且最终呈现所需技能的学习和规划完成这些任务。

Many theories, based on neuroscientific and psychological empirical evidence and on computational concepts, have been elaborated to explain the emergence of consciousness in the central nervous system. These theories propose key fundamental mechanisms to explain consciousness, but they only partially connect such mechanisms to the possible functional and adaptive role of consciousness. Recently, some cognitive and neuroscientific models try to solve this gap by linking consciousness to various aspects of goal-directed behaviour, the pivotal cognitive process that allows mammals to flexibly act in challenging environments. Here we propose the Representation Internal-Manipulation (RIM) theory of consciousness, a theory that links the main elements of consciousness theories to components and functions of goal-directed behaviour, ascribing a central role for consciousness to the goal-directed manipulation of internal representations. This manipulation relies on four specific computational operations to perform the flexible internal adaptation of all key elements of goal-directed computation, from the representations of objects to those of goals, actions, and plans. Finally, we propose the concept of `manipulation agency' relating the sense of agency to the internal manipulation of representations. This allows us to propose that the subjective experience of consciousness is associated to the human capacity to generate and control a simulated internal reality that is vividly perceived and felt through the same perceptual and emotional mechanisms used to tackle the external world.

Imitation learning techniques aim to mimic human behavior in a given task. An agent (a learning machine) is trained to perform a task from demonstrations by learning a mapping between observations and actions. The idea of teaching by imitation has been around for many years, however, the field is gaining attention recently due to advances in computing and sensing as well as rising demand for intelligent applications. The paradigm of learning by imitation is gaining popularity because it facilitates teaching complex tasks with minimal expert knowledge of the tasks. Generic imitation learning methods could potentially reduce the problem of teaching a task to that of providing demonstrations; without the need for explicit programming or designing reward functions specific to the task. Modern sensors are able to collect and transmit high volumes of data rapidly, and processors with high computational power allow fast processing that maps the sensory data to actions in a timely manner. This opens the door for many potential AI applications that require real-time perception and reaction such as humanoid robots, self-driving vehicles, human computer interaction and computer games to name a few. However, specialized algorithms are needed to effectively and robustly learn models as learning by imitation poses its own set of challenges. In this paper, we survey imitation learning methods and present design options in different steps of the learning process. We introduce a background and motivation for the field as well as highlight challenges specific to the imitation problem. Methods for designing and evaluating imitation learning tasks are categorized and reviewed. Special attention is given to learning methods in robotics and games as these domains are the most popular in the literature and provide a wide array of problems and methodologies. We extensively discuss combining imitation learning approaches using different sources and methods, as well as incorporating other motion learning methods to enhance imitation. We also discuss the potential impact on industry, present major applications and highlight current and future research directions.

最近的自主代理和机器人的应用，如自动驾驶汽车，情景的培训师，勘探机器人和服务机器人带来了关注与当前生成人工智能（AI）系统相关的至关重要的信任相关挑战。尽管取得了巨大的成功，基于连接主义深度学习神经网络方法的神经网络方法缺乏解释他们对他人的决策和行动的能力。没有符号解释能力，它们是黑色盒子，这使得他们的决定或行动不透明，这使得难以信任它们在安全关键的应用中。最近对AI系统解释性的立场目睹了可解释的人工智能（XAI）的几种方法;然而，大多数研究都专注于应用于计算科学中的数据驱动的XAI系统。解决越来越普遍的目标驱动器和机器人的研究仍然缺失。本文评论了可解释的目标驱动智能代理和机器人的方法，重点是解释和沟通代理人感知功能的技术（示例，感官和愿景）和认知推理（例如，信仰，欲望，意图，计划和目标）循环中的人类。审查强调了强调透明度，可辨与和持续学习以获得解释性的关键策略。最后，本文提出了解释性的要求，并提出了用于实现有效目标驱动可解释的代理和机器人的路线图。

从意外的外部扰动中恢复的能力是双模型运动的基本机动技能。有效的答复包括不仅可以恢复平衡并保持稳定性的能力，而且在平衡恢复物质不可行时，也可以保证安全的方式。对于与双式运动有关的机器人，例如人形机器人和辅助机器人设备，可帮助人类行走，设计能够提供这种稳定性和安全性的控制器可以防止机器人损坏或防止伤害相关的医疗费用。这是一个具有挑战性的任务，因为它涉及用触点产生高维，非线性和致动系统的高动态运动。尽管使用基于模型和优化方法的前进方面，但诸如广泛领域知识的要求，诸如较大的计算时间和有限的动态变化的鲁棒性仍然会使这个打开问题。在本文中，为了解决这些问题，我们开发基于学习的算法，能够为两种不同的机器人合成推送恢复控制政策：人形机器人和有助于双模型运动的辅助机器人设备。我们的工作可以分为两个密切相关的指示：1）学习人形机器人的安全下降和预防策略，2）使用机器人辅助装置学习人类的预防策略。为实现这一目标，我们介绍了一套深度加强学习（DRL）算法，以学习使用这些机器人时提高安全性的控制策略。

The concept of intelligent system has emerged in information technology as a type of system derived from successful applications of artificial intelligence. The goal of this paper is to give a general description of an intelligent system, which integrates previous approaches and takes into account recent advances in artificial intelligence. The paper describes an intelligent system in a generic way, identifying its main properties and functional components. The presented description follows a pragmatic approach to be used in an engineering context as a general framework to analyze and build intelligent systems. Its generality and its use is illustrated with real-world system examples and related with artificial intelligence methods.

Artificial life is a research field studying what processes and properties define life, based on a multidisciplinary approach spanning the physical, natural and computational sciences. Artificial life aims to foster a comprehensive study of life beyond "life as we know it" and towards "life as it could be", with theoretical, synthetic and empirical models of the fundamental properties of living systems. While still a relatively young field, artificial life has flourished as an environment for researchers with different backgrounds, welcoming ideas and contributions from a wide range of subjects. Hybrid Life is an attempt to bring attention to some of the most recent developments within the artificial life community, rooted in more traditional artificial life studies but looking at new challenges emerging from interactions with other fields. In particular, Hybrid Life focuses on three complementary themes: 1) theories of systems and agents, 2) hybrid augmentation, with augmented architectures combining living and artificial systems, and 3) hybrid interactions among artificial and biological systems. After discussing some of the major sources of inspiration for these themes, we will focus on an overview of the works that appeared in Hybrid Life special sessions, hosted by the annual Artificial Life Conference between 2018 and 2022.

在复杂的协作任务上共同努力需要代理商协调他们的行为。在实际交互之前明确或完全执行此操作并不总是可能也不充分。代理人还需要不断了解他人的当前行动，并迅速适应自己的行为。在这里，我们调查我们称之为信仰共鸣的精神状态（意图，目标）的效率，自动协调过程如何导致协作的解决问题。我们为协作剂（HAICA）提出了分层有源推断的模型。它将高效的贝叶斯理论与基于预测处理和主动推断的感知动作系统相结合。通过让一个药物的推断精神状态影响另一个代理人的预测信念来实现信仰共振，从而实现了他自己的目标和意图。这样，推断的精神状态影响了代理人自己的任务行为，没有明确的协作推理。我们在超核域中实施和评估此模型，其中两个代理具有不同程度的信仰共振组合，以满足膳食订单。我们的结果表明，基于HAICA的代理商实现了与最近现有技术方法相当的团队表现，同时产生了更低的计算成本。我们还表明，信仰共振在环境中特别有益，代理商是对环境的不对称知识。结果表明，信仰共振和有效推断允许快速高效的代理协调，因此可以用作合作认知剂的结构块。

有效推论是一种数学框架，它起源于计算神经科学，作为大脑如何实现动作，感知和学习的理论。最近，已被证明是在不确定性下存在国家估算和控制问题的有希望的方法，以及一般的机器人和人工代理人的目标驱动行为的基础。在这里，我们审查了最先进的理论和对国家估计，控制，规划和学习的积极推断的实现;描述当前的成就，特别关注机器人。我们展示了相关实验，以适应，泛化和稳健性而言说明其潜力。此外，我们将这种方法与其他框架联系起来，并讨论其预期的利益和挑战：使用变分贝叶斯推理具有功能生物合理性的统一框架。

在过去的十年中，自动驾驶航空运输车辆引起了重大兴趣。这是通过空中操纵器和新颖的握手的技术进步来实现这一目标的。此外，改进的控制方案和车辆动力学能够更好地对有效载荷进行建模和改进的感知算法，以检测无人机（UAV）环境中的关键特征。在这项调查中，对自动空中递送车辆的技术进步和开放研究问题进行了系统的审查。首先，详细讨论了各种类型的操纵器和握手，以及动态建模和控制方法。然后，讨论了降落在静态和动态平台上的。随后，诸如天气状况，州估计和避免碰撞之类的风险以确保安全过境。最后，调查了交付的UAV路由，该路由将主题分为两个领域：无人机操作和无人机合作操作。

Humans and animals have the ability to continually acquire, fine-tune, and transfer knowledge and skills throughout their lifespan. This ability, referred to as lifelong learning, is mediated by a rich set of neurocognitive mechanisms that together contribute to the development and specialization of our sensorimotor skills as well as to long-term memory consolidation and retrieval. Consequently, lifelong learning capabilities are crucial for computational systems and autonomous agents interacting in the real world and processing continuous streams of information. However, lifelong learning remains a long-standing challenge for machine learning and neural network models since the continual acquisition of incrementally available information from non-stationary data distributions generally leads to catastrophic forgetting or interference. This limitation represents a major drawback for state-of-the-art deep neural network models that typically learn representations from stationary batches of training data, thus without accounting for situations in which information becomes incrementally available over time. In this review, we critically summarize the main challenges linked to lifelong learning for artificial learning systems and compare existing neural network approaches that alleviate, to different extents, catastrophic forgetting. Although significant advances have been made in domain-specific learning with neural networks, extensive research efforts are required for the development of robust lifelong learning on autonomous agents and robots. We discuss well-established and emerging research motivated by lifelong learning factors in biological systems such as structural plasticity, memory replay, curriculum and transfer learning, intrinsic motivation, and multisensory integration.

在流行媒体中，人造代理商的意识出现与同时实现人类或超人水平智力的那些相同的代理之间通常存在联系。在这项工作中，我们探讨了意识和智力之间这种看似直观的联系的有效性和潜在应用。我们通过研究与三种当代意识功能理论相关的认知能力：全球工作空间理论（GWT），信息生成理论（IGT）和注意力模式理论（AST）。我们发现，这三种理论都将有意识的功能专门与人类领域将军智力的某些方面联系起来。有了这个见解，我们转向人工智能领域（AI），发现尽管远未证明一般智能，但许多最先进的深度学习方法已经开始纳入三个功能的关键方面理论。确定了这一趋势后，我们以人类心理时间旅行的激励例子来提出方式，其中三种理论中每种理论的见解都可以合并为一个单一的统一和可实施的模型。鉴于三种功能理论中的每一种都可以通过认知能力来实现这一可能，因此，具有精神时间旅行的人造代理不仅具有比当前方法更大的一般智力，而且还与我们当前对意识功能作用的理解更加一致在人类中，这使其成为AI研究的有希望的近期目标。
