The small tanks always felt a little too busy on the screen for me, especially when there is a big crowd of them. Could you add an alternate model?

I made a quick test with the compilatron and it seems to fit better into the factorio look:

Why not spitters?:

Maybe If I have some time one day, I will add a option for choosing different sprites :D

haha I also thought shortly about Biters

An option for different sprites would be awesome someday!

It shouldn't be too hard to make as a third party mod... Just need to replace the sprite definitions.

the demo animation looked really nice ... lucky me, that i just had finshed drinking something or else i would have showered my computer and keyboard :-)

how much a mod is liked can be seen by searching for its name on the mod portal and seeing how many additional mods are published: there now are 8 mods, from the mod itself, a modpack that includes it and some translation, to mods that modify this mod, eg removing the fuel requirement and most of all what this thread is about, giving a new look to the drones, letting them appear as small versions of logicarts ...

i personally would like to see them as little compilatrons, to match the construction drones and (when using the mod "I, Robot") also the mining drones.
