This research aims at developing and testing perception and manipulation strategies that will allow a robot to grasp and manipulate objects from a complex scene, e.g., an unstructured self-occluding heap of reflective metallic parts in manufacturing environments, or a heap of unknown/un-modeled and/or deformable waste materials in nuclear decommissioning or mixed waste recycling. The project addresses the key challenges mentioned in the call, namely, the grasping and manipulation of objects by robots using novel, hardware-independent, robust techniques, composed of modularisable subtasks. General strategies will be developed that will be reproducible on different hardware configurations. Indeed, from the outset, the project focuses on robustness and reproducibility, which are key concepts that connect all project objectives. The fundamental scientific questions addressed in the project can be summarized as follows: 1) Robust visual data collection, segmentation and production of sets of graspable features in complex and difficult real scenes, 2) Grasp planning based on grasping visible features (instead of object models) and hardware independent implementation of the grasping strategies, 3) Grasping or re-grasping strategies, to best enable desired post-grasp actions, and also based on extrinsic dexterity, namely the exploitation of the environment or the robot's dynamic capabilities, and 4) Integration of all project components into an operational scheme that will be implemented in the laboratory settings of all participants. Regarding visual data collection and analysis (item 1), algorithms capable of working in unstructured environments associated with uncertainty will be developed. The project will tackle difficult environments, which are characteristic of a variety of industrial applications. We note that industrial benchmark datasets are comparatively few in the vision and robotics research communities, despite their clear economic importance and also significant intellectual complexity. In item 2, the concept of graspable features will be developed and used to devise novel grasping strategies. Means of evaluating the performance of the manipulation strategies will also be developed in order to assess the quality of the results obtained. By managing the perception-action loop using the detection of graspable features, the project will also provide tools for potentially handling unknown objects in unknown environments. Item 3 follows the concept of graspable features since a graspable feature may yield a proper temporary grasp but may require re-grasping depending on the task to be performed. Finally, the integration of the project components will also raise issues of implementation, real-time constraints and other practical limitations. Experiments will be conducted in all participating research groups, initially using identical or similar equipment and then using different set ups and configurations in order to demonstrate generalisation, reproducibility and robustness. The perception aspect of the work will focus on visually complex, noisy and cluttered scenes. The manipulation aspect of the work will focus on generality and reproducibility, based on searching for graspable features rather than relying on object models. Finally, the project will generate a large amount of data, which will be logged, shared and made available to the international robotics research community as a set of public benchmark challenges, including training and testing data.

本研究旨在开发和测试感知和操纵策略，使机器人能够从复杂场景中抓取和操纵物体，例如，制造环境中反射金属部件的非结构化自闭塞堆，或核退役或混合废物回收中的一堆未知/未建模和/或可变形的废物。该项目解决了电话中提到的关键挑战，即机器人使用新颖的、硬件独立的、健壮的技术来抓取和操纵物体，这些技术由模块化的子任务组成。将开发可在不同硬件配置上重现的通用策略。事实上，从一开始，项目就关注健壮性和可再现性，这是连接所有项目目标的关键概念。项目中涉及的基本科学问题可以总结如下：1)在复杂和困难的真实场景中健壮的视觉数据收集、分割和可抓取特征集的生成；2)基于抓取可见特征（而不是对象模型）和抓取策略的硬件独立实施的抓取规划；3)抓取或再抓取策略，以最好地实现期望的抓取后动作，并基于外部灵巧性，即利用环境或机器人的动态能力。4)将所有项目组成部分整合到将在所有参与者的实验室环境中实施的操作方案中。关于可视化数据收集和分析（项目1），将开发能够在与不确定性相关的非结构化环境中工作的算法。该项目将解决各种工业应用所特有的困难环境。我们注意到，在视觉和机器人研究领域，工业基准数据集相对较少，尽管它们具有明显的经济重要性和显著的智力复杂性。在项目2中，可抓取特征的概念将被发展并用于设计新的抓取策略。还将开发评估操作策略性能的方法，以评估所获得结果的质量。通过检测可抓取的特征来管理感知-行动循环，该项目还将为在未知环境中潜在地处理未知对象提供工具。第3项遵循可抓特征的概念，因为可抓特征可能产生适当的临时抓握，但可能需要根据要执行的任务重新抓握。最后，项目组成部分的整合也会引起执行、实时限制和其他实际限制的问题。实验将在所有参与的研究小组中进行，最初使用相同或类似的设备，然后使用不同的设置和配置，以证明通用性，可重复性和稳健性。作品的感知方面将侧重于视觉上复杂、嘈杂和杂乱的场景。操作方面的工作将侧重于通用性和再现性，基于搜索可掌握的特征，而不是依赖于对象模型。最后，该项目将产生大量数据，这些数据将被记录、共享并提供给国际机器人研究界，作为一组公共基准挑战，包括训练和测试数据。
