Abstract: A watercraft propulsion system includes a propulsion unit to apply a propulsive force to a hull, and a controller configured or programmed to control the propulsion unit in response to a lateral movement command to cause the hull to move in a zig-zag pattern in a direction indicated by the lateral movement command between two parallel reference lines extending laterally of the hull and spaced apart from each other anteroposteriorly of the hull while maintaining an azimuth of the hull. The propulsion unit may include a bow thruster at the bow of the hull to generate a propulsive force laterally of the hull, a propulsion device on the hull to generate a propulsive force anteroposteriorly of the hull, and a steering to change the course of the hull.

Abstract: An image acquisition device for a work device performing a task on a target. The image acquisition device includes: an imaging device capturing an image of the target; and an imaging tool that includes a model of the work device and is operable by an operator. The imaging device is attachable to and detachable from each of the work device and the imaging tool, such that that a relative position between the imaging device and the model and that between the imaging device and the work device are identical when the imaging device is attached to the model and the work device. The imaging device captures a part of the model and a part of the work device along with the target when the imaging device is respectively attached to the imaging tool and the work device, the part of the model corresponding to the part of the work device.

Abstract: A control system for posture control tabs of a marine vessel assists operations of a steering control. The posture control tabs are mounted on a stern of a hull to move up or down to control a posture of the hull. Actuators actuate the respective posture control tabs. When a steering instruction is provided through the steering control, a processor determines the posture control tab to be actuated and controls the actuator corresponding to the posture control tab determined to be actuated so as to change the position of the determined posture control tab.

Abstract: A transfer operation of moving the slider between one fixed linear module and a movable linear module while locating the movable linear module in the facing range facing the one fixed linear module is performed. At this time, it is judged whether or not the coordinate axis of the one fixed linear module and the coordinate axis of the movable linear module are continuous If it is judged before the transfer operation that the coordinate axes are not continuous, the transfer operation is performed after the coordinate axes are made continuous in the direction by changing the coordinate axis. Thus, it is possible to suppress the occurrence of a situation where the transfer operation of moving the slider between the fixed linear module and the movable linear module cannot be performed due to the discontinuity of the coordinate axes respectively set for the fixed and movable linear modules.

Abstract: A propulsion device for a marine vessel includes an engine and a forward/reverse shifting mechanism. The direction of a propulsive force generated by the propulsion device is changed according to a shift position of the forward/reverse shifting mechanism. The shift position is changeable between a forward position and a reverse position via a neutral position. In response to a command signal based on an operation of a joystick or an operator, the shift position of the forward/reverse shifting mechanism and the engine are controlled. When the shift position of the forward/reverse shifting mechanism is changed from the neutral position to a position corresponding to a direction opposite to a travelling direction of the marine vessel, which is determined based on the speed of the marine vessel, a correction control is performed to increase an output of the engine based on the speed of the marine vessel.
