Abstract
The present invention relates, in general, to systems and methods for controlling autonomous forklifts, and specifically, for maneuvering autonomous forklifts in environments where there is low overhead clearance or overhead obstacles. The invention determines the height of an overhead obstacle as well as the height of a pallet carried by the autonomous forklift, and also determines if the overhead obstacle is deformable or non-deformable. The autonomous forklift is commanded to either traverse through the overhead obstacle if the height of the pallet is smaller than the height of the overhead obstacle, or if the overhead obstacle is deformable, such as in the case of weather guards surrounding a dock door.
