Grid-based path planning and optimization remain widely used in robotics and autonomous navigation because real environments can be discretized into binary occupancy grids, allowing algorithms such as A* to guarantee a solution whenever a collision-free path exists. However, the resulting grid paths are often subop...

Human–robot interaction (HRI) and navigation in crowded indoor spaces require robots to reason not only about where humans may be but also about whether uncertain human motion conflicts with the robot’s intended path. Existing context-aware particle filtering (CA-PF) provides a useful belief-estimation backbone by main...

Reliable object picking is a key requirement for delivery drones, but precise hovering above a pickup point remains difficult in outdoor environments because of GPS inaccuracy, lighting variation, occlusions, and temporary target loss. This highlights the need for an integrated hovering system that can provide accurate...

Uncrewed aerial vehicles increasingly rely on on-board deep object detectors for applications such as surveillance, delivery, agriculture, and traffic monitoring. The vulnerability of these detectors to adversarial patches has therefore become a practical safety concern. Research on adversarial patch and camouflage att...
