Work in dangerous environments such as Urban Search and Rescue (USAR, the post-disaster exploration and mapping of structures, searching for victims and aiding disaster response) represents an extreme challenge to teams of intelligent robots. The world is complex and unpredictable, robots can be damaged or destroyed, and communication is interfered with due to damaged infrastructure. Teams consisting of various types of robots (heterogeneous teams) are required, because the risk involved in losing units can be better amortized with larger numbers of more expendable individuals. Under such conditions, teams must form and reorganize dynamically around the mix of individuals available at any time, doing useful work with the skills available, actively looking for new individuals to supplement skills, and making use of damaged individuals to the degree practicable (including assisting these if possible). Individuals must similarly adapt to damage (e.g. make use of grasping limbs if no longer mobile) and work with a team as well as possible. Permeating all of this, risk must be actively balanced with the value of carrying out any task for the team, and these tasks must all be accomplished under rapid change and limited communication.******The program of research proposed here will advance the state of the art in dynamic heterogeneous robotic teamwork in dangerous environments, incorporating and extending all of the above themes. Work has been done in these themes individually (e.g. task allocation on changing teams, recruiting agents) but a deployable decentralized solution supporting a broad collection of robots for a domain as dangerous as USAR is still elusive. In recent work my students and I have developed a framework for this purpose that includes accomplishing tasks under changing team membership, adapting to robot loss and recruiting new individuals. We have also been working on improved robot control and planning for complex domains. I will be leveraging this experience to more broadly advance dynamic heterogeneous teamwork, encompassing major issues such as managing damaged robots to the best extent possible, assisting damaged robots, balancing task risk vs. value, and developing team strategies to manage risk. The outcome of this will be a software system that will be physically demonstrated using teams of robots in the real world. We will be exploring the use of humanoid robots in particular on teams under these conditions, since the nature of this form supports a broad range of activities despite damage (e.g. humanoids can crawl or drag themselves if unable to walk). This work is applicable in a broad range of dangerous domains beyond USAR, such as mining, space exploration, and defense.******The proposed research will provide valuable training for four PhD students and nine MSc students in artificial intelligence, complex software development, and robotics: skills that are vitally needed by industry.**

在危险环境中工作，如城市搜索和救援（USAR，灾后探索和绘制结构图，搜索受害者和协助灾害响应），对智能机器人团队来说是一个极端的挑战。 世界是复杂和不可预测的，机器人可能会被损坏或摧毁，通信也会因基础设施受损而受到干扰。 需要由各种类型的机器人组成的团队（异质团队），因为损失单位的风险可以通过更多的可消耗个体来更好地分摊。在这种情况下，团队必须围绕随时可用的人员组合动态地形成和重组，利用可用的技能做有用的工作，积极寻找新的个人来补充技能，并在可行的程度上利用受损的个人（包括在可能的情况下协助这些人）。 同样，个人也必须适应损害（例如，如果不再移动的，则使用抓握肢体），并尽可能与团队合作。 贯穿所有这一切，风险必须与团队执行任何任务的价值积极平衡，这些任务必须在快速变化和有限沟通的情况下完成。这里提出的研究计划将推进危险环境中动态异构机器人团队合作的最新技术水平，结合并扩展上述所有主题。 这些主题的工作已经单独完成（例如，改变团队的任务分配，招募代理），但一个可部署的分散解决方案支持广泛的机器人集合，用于像USAR这样危险的领域仍然是难以捉摸的。 在最近的工作中，我和我的学生为此开发了一个框架，包括在不断变化的团队成员中完成任务，适应机器人的损失和招募新的个人。 我们还一直致力于改进机器人控制和复杂领域的规划。 我将利用这一经验更广泛地推进动态异构团队合作，包括主要问题，如尽可能最大限度地管理损坏的机器人，协助损坏的机器人，平衡任务风险与价值，以及制定团队战略来管理风险。 其结果将是一个软件系统，将在真实的世界中使用机器人团队进行物理演示。 我们将探索人形机器人的使用，特别是在这些条件下的团队中，因为这种形式的性质尽管受到损坏，但仍支持广泛的活动（例如，如果无法行走，人形机器人可以爬行或拖动自己）。 这项工作适用于USAR以外的广泛危险领域，如采矿，太空探索和国防。拟议的研究将为四名博士生和九名硕士生提供人工智能，复杂软件开发和机器人技术方面的宝贵培训：这些技能是行业急需的。
