• Abstract: Sociability is essential for modern robots to increase their acceptability in human environments. Traditional techniques use manually engineered utility functions inspired by observing pedestrian behaviors to achieve social navigation. However, social aspects of navigation are diverse, changing across different types of environments, societies, and population densities, making it unrealistic to use hand-crafted techniques in each domain. This paper presents a data-driven navigation architecture that uses state-of-the-art neural architectures, namely Conditional Neural Processes, to learn global and local controllers of the mobile robot from observations. Additionally, we leverage a state-of-the-art, deep prediction mechanism to detect situations not similar to the trained ones, where reactive controllers step in to ensure safe navigation. Our results demonstrate that the proposed framework can successfully carry out navigation tasks regarding social norms in the data. Further, we showed that our system produces fewer personal-zone violations, causing less discomfort.

  We present a study on learning social robot navigation with multimodal perception using a large-scale real-world dataset. We compare unimodal and multimodal learning approaches against a set of classical navigation approaches in different social scenarios. The results show that multimodal learning has a clear advantage over unimodal learning in both dataset and human studies.

  Social robot navigation is difficult to evaluate because it involves dynamic human agents and their perceptions of the appropriateness of robot behavior. Our contributions include (a) a definition of a socially navigating robot as one that respects the principles of safety, comfort, legibility, politeness, social competency, agent understanding, proactivity, and responsiveness to context, (b) guidelines for the use of metrics, development of scenarios, benchmarks, datasets, and simulators to evaluate social navigation, and (c) a social navigation metrics framework to make it easier to compare results from different simulators, robots and datasets.
