Many 'of' in one sentence

[TomKQT]

Hello,
I sometimes make a sentence with a lot of 'of', something like this:

The second part concerns with creation of a complex simulation system for verification of characteristics of virtual models of wheeled mobile robots.

How does it sound to native English speakers? Is it fine or should the repetitive 'of' be avoided? And how?

Thank you very much in advance.

The second part concerns with creation of a complex simulation system for verification of characteristics of virtual models of wheeled mobile robots.

A passable version:
The second part deals with creation of a complex simulation system designed for verification of characteristics of wheeled mobile robot virtual models.

A worse version:
The second part deals with creation of a complex simulation system designed for verification of wheeled mobile robot virtual models' characteristics.

The worst version:
The second part deals with creation of a wheeled mobile robot virtual models characteristics verification complex simulation system.

The second part is concerned with the creation of . . .

Start like this and the sentence is fine as is.

If I hadn't known in advance to expect a few ofs, I'm sure they wouldn't have impinged upon my consciousness.

Avoiding the repetition of words is good general advice for literary writing, but there's no point in trying to restructure the sentence to avoid it in technical texts such as this, where clarity of expression is more important than literary style. (I used literary twice just then, but I don't care.)

I know about this alternative way how to formulate "of", but in this particular case it simply didn'l look good to me. As you marked them yourself: "worse, worst".

So, the original question - is it fine even with all those of's? I would never write anything like that in my language, but we don't have such an auxiliary word as 'of'.

EDIT: Thx Rover_KE, you answered it!
