A safety device includes a first computation unit, a second computation unit, an output control unit, and a first central processing device. The first computation unit is configured to perform a first computation on a detected value detected from a subject to be controlled, thus obtaining a first result value. The second computation unit is configured to perform a second computation on the detected value, thus obtaining a second result value which is to be determined if equal to the first result value. The output control unit is configured to output the first result value in a case that the second computation unit determines that the first result value is equal to the second result value, and not to output the first result value in a case that the second computation unit determines that the first result value is not equal to the second result value.

A submersible vehicle is a type having swinging wings. The vehicle is provided with a vehicle main body, a plurality of swinging wings provided for the main body and arranged in series, rotatable shafts located at front edges of the swinging wings, respectively, actuators for driving the shafts independently of one another, and a wing controller for controlling the actuators in such a manner that the wings enable to swing in a flexible manner like the tail fin of a fish, thereby producing a desired propelling force and performing a steering operation.
