Dynamic Synthesis of Three−Point Circle Peripheral Docking Technology Pose

Round 1

Reviewer 1 Report

The manuscript entitled " Dynamic Synthesis of Three-Point Circle Peripheral Docking Technology Pose", can be considered for publication in applied sciences after a minor revision.

Here is a list of my comments:

1.     Please include the full definition used in the manuscript, such as FREND, VA, UPS-PS, GPS, SLAM, etc.

2.     What is the range of the turning radius could be achieved, as shown in Figure 6?

3.     The type of optimization method used is not mentioned in the manuscript (line#271).

4.     The software or program used for simulation analysis is not mentioned in the methodology.

5.     Please briefly mention which D- and T-vehicle were used in the analysis. Do both vehicles have a similar specification considered a constant in the experiment?

6.     The quality of Figures 11(c)-(e) is low, and the legend and the number on the y-axis are blurry.

7.     What causes the fluctuation in Figure 12(d)? Please briefly discuss.

Reviewer 2 Report

1. Spelling error (flfloating) (in line 456) (Reference 14).

2. Spelling error (demonstration) (in line 460) (Reference 16).

3. What is -RTt, (in line 275)?

4. Is the docking rod in the active vehicle or target vehicle? (line 296)

5. Should not the kinetic energy be 0.52 N.m rather than 0.57 N.m because the kinetic energy has already reduced to 0.52 N.m during the process of docking (line 297)?

6. When the kinetic energy has already fallen, due to deceleration, from 2.35 Nm to 0.15 N.m, why another deceleration approach is necessary (line 299)?

7. When the maximum force on the connecting rod of the driving car is about 900 N (line 304), how can the counter-acting force be 2300 N (line 307)?

8. What is the coefficient of restitution during the collision process?

9. Is the recovery coefficient same as coefficient of restitution? 

10. "...independently driven by four wheels..." is it a 4 wheel drive (line 344)?

11. What do you mean by grass tires (line 346)?

12. Is the receiving frequency in Hz or m/s (line 361)?

13. Has the error analysis been done of the various hardware instruments?

14. How could you compare the experimental and simulation results for kinetic energy and force using the results from the gyroscope?

15. Is not strain gauge a good tool to be used for measuring forces?

16. Image of experimental setup is not seen.

17. How is the magnetic suction system related to acceleration of the vehicle (line 372)?

18. Work is good. 

19. What are the practical applications of this work other than space applications?

20. "...the force on the docking rod of the driving car under oblique collision in Condition 2 is significantly less than that under normal collision in Condition 1..." (line 394). Won't there be twisting in the rod due a turning moment although force may be less?

21. What is the calibration done (line 402)?
