Multiple-chоice questiоns In the fоllowing stаtement on VFH locаl nаvigator, which one is incorrect? (a) In the VFH local navigator, Cartesian Histogram Grid: A 2D grid is constructed using the robot's range sensor data. This grid maps obstacles in the robot's environment, representing their positions in Cartesian coordinates relative to the robot. (b) In the VFH local navigator, Candidate Valleys: Within the polar histogram, consecutive sectors with obstacle densities below a predefined threshold are identified as candidate valleys. These valleys are evaluated based on their alignment with the target direction, guiding the robot toward an optimal path while avoiding obstacles. (c) In the VFH local navigator, Polar Histogram: The Cartesian histogram is then transformed into a one-dimensional polar histogram. This representation focuses on the robot's immediate surroundings by considering distance to obstacles in angular sectors centered around the robot's current location. (d) VFH is currently one of the most popular local planners used in mobile robotics, competing with the later developed dynamic window approach (DWA).
