Title:
GEOLOGICAL SAMPLE COLLECTING METHOD AND WORK DEVICE ALLOWING FOR ORIENTATION CONTROL
Document Type and Number:
WIPO Patent Application WO/2017/146135
Kind Code:
A1
Abstract:
A work device capable of collecting a core sample of seabed stably and at a desired angle includes, as the basic configuration, a fuselage 10, four flippers 30 pivotably provided to the left/right of the front portion and the left/right of the back portion of the fuselage 10, and a coring mechanism 20 provided to the fuselage 10. The fuselage 10 is provided with an inclination sensor 17 that detects the inclination in the front-back direction and the left-right direction. A load sensor 49 is attached to a support structure 40 that pivotably supports the flippers 30. On the basis of inclination information from the inclination sensor 17 and landing information about the flippers 30 from the load sensor 49, a controller 16 pivot-controls the four flippers 30, adjusts the fuselage 10 to a desired orientation, such as a horizontal orientation, and lands at least three of the flippers 30. After the orientation control, the controller 16 moves a coring mechanism 20 and collects a core sample from the seabed.
