Abstract
The use of unmanned systems is a rapidly expanding component of operations aboard naval vessels and has the potential to significantly improve the onboard safety and efficiency. Because of the complexity of many shipboard environments, where humans and unmanned systems will be working simultaneously, realizing this potential will require precise and accurate robot localization. This thesis investigates the performance of a relatively low-cost, commercial-off-the-shelf, ultra-wideband (UWB) positioning system to support human-machine teaming onboard naval vessels. This investigation includes a quantitative comparison of the UWB positioning system with a high-cost, high-accuracy, optoelectronic motion capture positioning system. To provide further context, the performance of intrinsic robot navigation through feature-based computer-vision navigation is examined. This research suggests that UWB positioning provides the sufficient precision and relative accuracy for many applications onboard naval vessels and presents a discussion of the contrast between extrinsic positioning and intrinsic feature-based, computer-vision navigation, highlighting the tradeoffs between the approaches.
