What we have done • Mapping • A-floor corridors map from sonar sensor • Motion control • Way point local planner • Path planning with D* algorithm • Grid base algorithm with 4 connectivities • Dynamic obstacle detection and rebuilding map from sonar sensor • Kalmanfiletering with Sonar sensor • Current position estimation • Image processing with camera vision synchronize • Deterministic current position and orientation synchronization
Strengths and weaknesses • Motion control • low sliding due to reduced velocity • big angular movements • Path planning with D* algorithm • quick computation on the robot pc • coarse grid resolution forced to use 4 neighbors • Kalmanfiletering with Sonar sensor • effective tool to filter noisy sonar data • Image processing with camera vision synchronize • high precision in “good regions” but big errors outside these areas
