UAV Sediment Sampling in Intertidal Zones Without Manual Access

The patent introduces an unmanned aerial vehicle (UAV) as an intermediary platform between the ship and the intertidal zone sampling location. The UAV carries the sampler and operates independently in the intertidal zone, eliminating the need for personnel to work in dangerous conditions while maintaining sampling capability. This mediator approach resolves the contradiction by transferring the sampling function to an autonomous platform that is not constrained by tide timing or safety concerns.

The patent makes the sampling platform dynamic by using a UAV that can freely move and hover over the intertidal zone rather than being fixed to a ship. The UAV can position itself precisely at any sampling location and remain stationary for extended periods to complete sampling operations. This dynamic capability eliminates the constraint of limited high tide duration, as the UAV is not dependent on tide schedules for operational timing.

The patent replaces the mechanical system of manual sampling with an automated UAV-based sampling system. Instead of personnel physically walking on and operating samplers in the soft intertidal sediment, the UAV autonomously positions and deploys the sampler. This substitution eliminates the need for human presence in the unstable ground conditions, resolving the contradiction between ease of operation and safety by making the system both easy to operate remotely and safe from ground collapse hazards.
