Query: Asynchronous Collaborative Localization by Integrating Spatiotemporal
  Graph Learning with Model-Based Estimation   Collaborative localization is an essential capability for a team of robots
such as connected vehicles to collaboratively estimate object locations from
multiple perspectives with reliant cooperation. To enable collaborative
localization, four key challenges must be addressed, including modeling complex
relationships between observed objects, fusing observations from an arbitrary
number of collaborating robots, quantifying localization uncertainty, and
addressing latency of robot communications. In this paper, we introduce a novel
approach that integrates uncertainty-aware spatiotemporal graph learning and
model-based state estimation for a team of robots to collaboratively localize
objects. Specifically, we introduce a new uncertainty-aware graph learning
model that learns spatiotemporal graphs to represent historical motions of the
objects observed by each robot over time and provides uncertainties in object
localization. Moreover, we propose a novel method for integrated learning and
model-based state estimation, which fuses asynchronous observations obtained
from an arbitrary number of robots for collaborative localization. We evaluate
our approach in two collaborative object localization scenarios in simulations
and on real robots. Experimental results show that our approach outperforms
previous methods and achieves state-of-the-art performance on asynchronous
collaborative localization.
