Two Minds for One Vehicle: A Case Study in Deliberative and Reactive Navigation
… software. Both vehicles proved capable of off-road navigation, including road following and obstacle avoidance in complex desert terrain. In the end, however, the reactive paradigm proved to be smoother and more reliable than the deliberative paradigm under the conditions of our testing. While …

Reactive Navigation of an Autonomous Ground Vehicle Using Dynamic Expanding Zones
Autonomous navigation of mobile robots through unstructured terrain presents many challenges. The task becomes even more difficult with increasing obstacle density, at higher speeds, and when a priori knowledge of the terrain is not available. Reactive navigation schemas are often dismissed as …

Inferring Network Status from Partial Observations
… the one from WAZE. WAZE is a crowd-sourced road navigation tool, that collects and presents the traffic incident reports. We found that the proposed greedy algorithm for this problem is able to recover $80%$, on average, of the failed nodes in a network for a given partial sample of input …

Terrain aware tactical motion planning and control algorithms for off-road UGVs in GNSS denied hostile environments
… tactical motion planning and control of off-road unmanned ground vehicles operating in environments where global navigation satellite systems are unavailable due to adversarial interference or structural constraints. The research focuses on enabling autonomous navigation in uncharted, hostile …

Threat and Application of Frequency-Agile Radio Systems
… radio to stealthily manipulate GPS-based road navigation systems without alerting human drivers. A novel attacking algorithm is proposed, where the frequency-agile radio transmits fake GPS signals to lead the victim to drive on a wrong path that looks very similar with the navigation route …
