Example 2:
further description is given in connection with example 1: when the ship body 1 is of a single ship structure, the ship body 1 is simple in structure, low in investment of the whole device, low in cost and convenient to move.
When the ship body 1 is of a double-ship structure, the double ships are fixedly connected, the whole structure is not easy to turn on one side, and the ship body 1 is required to have high stability because large waves are often generated in the sea. In the path planning of oil collection, a ship body 1 structure is required to have a smaller turning radius so as to execute an S-shaped intelligent path planning scheme. Two propellers of the catamaran can ensure a very small turning radius by rotating positively and negatively at the same time.
