The present disclosure provides an underwater helicopter with cycloidal rim vector propulsion. The underwater helicopter includes a disc-shaped underwater helicopter hull, a rim driving mechanism, paddles and rotation adjusting mechanisms. The rim driving mechanism is annular, and the diameter size of the rim driving mechanism is matched with the circumference size of the disc-shaped underwater helicopter hull. The rim driving mechanism is fixedly installed in a cavity in the circumference of the disc-shaped underwater helicopter hull. The rotation adjusting mechanisms are uniformly and fixedly installed on the outer side of the rim driving mechanism. The paddle is fixedly connected with the rotation adjusting mechanism.

An underwater vehicle may be configured to perform vertical profiling and diagonal profiling. The vehicle may include a body having an elongated shape with a central longitudinal axis orthogonal to a central lateral axis. The vehicle may include lateral control surfaces. The lateral control surfaces may be disposed outside of the body and mechanically coupled with the body at a position proximal to the central lateral axis. The lateral control surfaces may be configured to rotate about a control axis parallel to the central lateral axis in order to control an attitude of the vehicle during ascent or descent. A given one of the lateral control surfaces may have a portion extend from the mechanical coupling in a direction perpendicular to the control axis.
