Suggestion about fixed bots

<< < (2/2)

Jez:

--- Quote from: Testlund ---I think bots shouldn't be able to appear on top of each other which makes several hundred bots look like one bot. Even if they are fixed they should still bump away from each other or at least only stay very close and form colonies. Anyone agrees?

Yessir!

My thoughts are that there should be a cost associated with being fixed, something I have no problem with, and that if a bot bumps into a fixed bot the cost to remain fixed should rise proportionally.

Changing fixed to a

sounds cool but I haven't got my thinking hat on so I'm not going to work out what that actually means for now.  

Testlund:

--- Quote from: EricL ---The whole concept of a fixed bot is kind of weird IMHO and is inelegant and unrealistic from a physcis perspective (so are moving shapes BTW).

Imagine that DB is a square shaped dish with a few millimeter water depth and the shapes are flat rocks and weed slowly drifting around, and the bots live in between.

--- Quote from: Numsgil ---Added mass isn't an unrealistic concept at all.  Just because you've never heard of it before...  I wrote the wiki article on it, feel free to go check it out here.  The talk page has a nice dialogue between me and another naysayer that should convince you that I'm not just making things up

Well, I stand corrected, it does make sense. But it opens a very big can of worms: the calculation is only valid for an isolated sphere. If you put two bots close together, there are many effects of the same magnitude that should be taken into account as well.

Yep, but fluid mechanics quickly gets insane.  Blood starts seeping from your ears.  And then you realize that Darwinbots isn't about fluid mechanics and you've researched so much and most of it hardly matters at all.  And then your mind explodes.

If you would like to tackle the problem of fluid physics in general, I'll support you 100%.
