Modern autonomous robotic platforms are equipped with a variety of sensors including cameras [1], infrared sensors [2], lidar [3], and radar [4]. Despite this variety of sensors, many robots rely exclusively on lidar for localization [3]. The U.S. Naval Research laboratory is interested in developing novel perception algorithms which can identify optimal sensing strategies based on mission level decisions or environmental conditions. Algorithms should be robust to a variety of real-world constraints, such as adapting to visually degraded environments, modulating probability of detection, operating in very limited SWaP envelopes, etc. A key goal in this research is to explore emerging technologies in multi-modal perception on embodied platforms, and applying data-driven solutions to determine optimal sensor selections for estimating the location of agents. These should be scalable to a variety of platforms using varying compute and subsets of common sensors.
Applicants should have an extensive background in field robotics applications and experience in a subset of the following areas: Machine learning, state estimation, robotic perception, sensor fusion, factor graphs, and statistical analysis.
