An Innovative Pose Control Mechanism for a Small Rudderless Underwater Vehicle
Round 1
Reviewer 1 Report
The reviewed article presents an interesting solution to the problem of controllingan underwater vehicle. In the opinion of the reviewer, the problem of vehicle stability in the neutral position
of the masses remained inexplicable. Further research should focus on experiments
confirming the stable behavior of the vehicle when the vehicle is moving forward.

Reviewer 2 Report
The authors have proposed a novel design for the autonomous underwater vehicle where rudders are not utilized for pitch and yaw control. The AUV design is based on the use of a mass shifter mechanism. The authors have fabricated the proposed AUV and tested it in the underwater environment for demonstrating the feasibility of the design. The paper is well written and the results are clearly presented. I have a few minor comments which can be easily incorporated into the revised manuscript.
- Have the authors carried out the CFD analysis of the preliminary design of the hull to measure its drag and total thrust produced by the propeller?
- Are the authors using an off-the-shelf propeller? Or is it custom designed propeller specific to the AUV?
- If the authors have used the commercial propeller, how did they go about selecting the propeller? Did they perform some preliminary analysis to calculate the design point for the propeller? For more details, the authors can refer to this paper (S. Pawar, S. Brizzolara, W. L. Neu and D. J. Stilwell, "Design of Ducted Propulsors for Towing Autonomous Underwater Vehicles," OCEANS 2018 MTS/IEEE Charleston, 2018, pp. 1-8, doi: 10.1109/OCEANS.2018.8604688.)
- Can this mass shifter mechanism be adopted for control of AUV which has a shape similar to the Myring hull? What are the challenges in adopting this type of control mechanism in those types of AUVs?
