Automatic Spray Trajectory Optimization on Bézier Surface
Round 1
Reviewer 1 Report
1- The authors published 2 papers on similar data with several other conference papers, one that is very close to this study is entitled "Trajectory Optimization of Spray Painting Robot for Complex Curved Surface Based on Exponential Mean Bézier Method, Mathematical Problems in Engineering, Vol. 2017" could the authors go over the differences in the study/design between the 2 publications and identify why there is a need to have a 4th paper with little changes in the results.
2- please compare the results between the two pervious publications "Coatings, Sep. 2017 and Mathematical Problems in Engineering, Nov., 2017"

Reviewer 2 Report
- Given the number of variables in the equation, a nomenclature page defining all the variables might be required
- Fig 3. needs improvement, its hard to read the variables

Round 2
Reviewer 1 Report
The authors rebuttal to my comments need to be incorporated into the paper. it will make it stronger.
