  This paper presents a path planning method for partial field coverage.
Therefore, a specific path planning pattern is proposed. The notion is that
lighter machinery with smaller storage tanks can alleviate soil compaction
because of a reduced weight, but does not enable full field coverage in a
single run because of the smaller storage capacity. This is relevant for
spraying applications and related in-field work. Consequently, multiple returns
to a mobile or stationary depot located outside of the field are required for
storage tank refilling. Therefore, a suitable path planning method is suggested
that accounts for the limited turning radii of agricultural vehicles, satisfies
compacted area minimisation constraints, and aims at overall path length
minimisation. The benefits of the proposed method are illustrated by means of a
comparison to a planning method based on the more common AB pattern. It is
illustrated how the proposed path planning pattern can also be employed
efficiently for single-run field coverage.
