The result of the finite difference operation. Drives the vehicle in a pattern like a lawnmower search pattern. Bearing followed when moving forward in the survey. Number of times to move forward in the survey. Desired width of each leg, to the left of the starting point. Desired width of each leg, to the right of the starting point. Desired distance to move forward at the end of each leg. Set to true to start survey by driving to the left. Otherwise drive to the right. If this is set to true and leftWidth is zero or unset, start moving forward along the left edge. If this is not set to true and rightWidth is zero or unset, start moving forward along the right edge.
