摘要:

自主导航是辅助和服务机器人的关键技能。为了取得成功,机器人必须最大限度地减少移动时对人类造成的干扰。这意味着预测人们将如何移动并遵守社会习俗。避免破坏个人空间,人们的路径和互动是这些社会习俗的例子。本文利用图神经网络来建模机器人中断考虑人和机器人的运动,使所建立的模型可以使用的路径规划算法。随着模型的发展,本文提出了考虑机器人和人类运动的数据集SocNav1 [25]的演变,以及使用不同图神经网络块进行测试的更新的图形到图形转换。经过训练的模型在数据集中实现了接近人类的性能。除了准确性之外,该方法的主要优点还在于与手工模型相比,可以考虑的社会因素数量的可扩展性。数据集和模型在公共存储库(https://github.com/gnns4hri/sngnnv2)中可用。

英文摘要:

Autonomous navigation is a key skill for assistive and service robots. To be successful, robots have to minimise the disruption caused to humans while moving. This implies predicting how people will move and complying with social conventions. Avoiding disrupting personal spaces, people's paths and interactions are examples of these social conventions. This paper leverages Graph Neural Networks to model robot disruption considering the movement of the humans and the robot so that the model built can be used by path planning algorithms. Along with the model, this paper presents an evolution of the dataset SocNav1 [25] which considers the movement of the robot and the humans, and an updated scenario-to-graph transformation which is tested using different Graph Neural Network blocks. The model trained achieves close-to-human performance in the dataset. In addition to its accuracy, the main advantage of the approach is its scalability in terms of the number of social factors that can be considered in comparison with handcrafted models. The dataset and the model are available in a public repository (https://github.com/gnns4hri/sngnnv2).
