And, while at it, milk as a liquid storable in tanks. Should be relatively low probability.

Possibly. I'm not sure how entity interation should work though, as the general idea asie had for robots was to decrease their number, not add more.

Would like to see milk in tanks at least. For some reason that bugged me a lot.
I'm more interested in a fishing robot first.

maybe allow the harvester robot to do it if you provide it with a bucket?

planned for 8.0?

Forestry have it already. Soo FluidDictionary or talk (about removing it from Forestry) to @SirSengir?
Or low probability =(

Fluids by default have a "dictionary" like approach. They're registered under a unique ID, and unless you need something specific, you can simply check to see if it already exists and use the implementation, or register your own if it doesn't.

Milk-bots!! Another great addition if possible? Another step towards a fully automated farm.

Soon (tm)
