Algorithms for autonomous urban navigation with formal specifications
… motivated from an autonomous car navigating an urban landscape while following road safety rules such as "always travel in the left lane" and "do not change lanes frequently" or an electric vehicle in a mobility-on-demand scenario. The second part of the thesis focuses on multi-agent control …

Cognitive Map Generation for Vision and Language Navigation
<p>Visual-Language Navigation (VLN) presents significant challenges for autonomous agents, such as robots and virtual assistants, particularly in complex, dynamic environments where the seamless integration of visual perception and natural language understanding is critical. Traditional VLN systems …

Robust sampling-based motion planning for autonomous vehicles in uncertain environments
… uncertainty in its own motion. To provide safe navigation under such conditions, motion planning algorithms must be able to rapidly generate smooth, certifiably robust trajectories in real-time. The primary contribution of this thesis is the development of a real-time motion planning framework …

Technological framework for ubiquitous interactions using context–aware mobile devices
… system can assist the users in their tasks (e.g. navigation) without explicit input – e.g. by simply creating a gesture with the device. However, advanced interaction with the application via the user interface is available for requests that are more complex. Representations of the real world …

Decentralized collaborative localization in urban environments with inter-agent ranging and 3D-mapping-aided (3DMA) GNSS
… aerial vehicles (UAVs) and self-driving cars in urban environments for tasks such as transport, delivery, photography, surveillance and search and rescue. Global Navigation Satellite System (GNSS) navigation in urban environments is prone to error sources such as multipath and signal blockage due …
