Recently, I thought about an idea involving taming Crundles (possibly changing their PET_EXOTIC tag to just PET for my very first mod, so I wouldn't need a DM) and using them to explore caves, though everything I know about pets suggests they'd just gather in meeting places and idle. I'd rather not micromanage leading them around by declaring and then removing meeting activity zones.
Then, while browsing the mechanics section of the DF Wiki, a new idea hit me: Is it possible to mod a workshop so that you can make a creature at a workshop? If so, I think it'd be neat to build a sort of robot explorer.
Raw materials:
2 mechanisms
1 cut gem (for an eye, magic power source, whatever)
1 wood log/metal bar
For the creature shape and description, I was thinking a sort of four-legged spider, like a miniature version of that walking eye from Johnny Quest.
Tags that come to mind:
No Eat/No Sleep/No Drink/No Breathe and other tags that would signify it as a non-living creature.
Flee Quick: It avoids combat and has no attacks.
Meander: Random movement is probably best if you can't control it.
Castes: Could different versions exist, like a fire immune one if you made it out of fire safe materials?
I do see a lot of difficulties, though: If it's not a pet, how can it reveal previously hidden areas? You also run the risk that it could cause mass interruptions if it's treated like a non-tame animal, at least before you cage it and release it in the caverns. And, most importantly, if you can't make creatures at a custom workshop, this whole discussion is moot.
So, any thoughts?
