Zmiy Droid 12.7 is a Ukrainian armored unmanned ground combat system that combines Rovertech's Zmiy wheeled platform, DevDroid's Wolly 12.7 remote weapon station, and the Droid Box control system. Official Ukrainian and manufacturer sources present it as a remotely operated reconnaissance and fire-support robot with a 300-round 12.7 mm ammunition load, AI-assisted target tracking, and enough platform protection to reduce infantry exposure in high-risk areas of the 2014 Russia-Ukraine War.
Ukraine's Ministry of Defence authorized Zmiy Droid 12.7 for operational use by the Defence Forces in the 2014 Russia-Ukraine War; public sources describe the system as a Rovertech Zmiy platform with DevDroid's Wolly 12.7 turret and Droid Box control system for reconnaissance, fire support, and remote engagement.
Role detailsDevDroid's public ground-robot line uses Droid Box and Wolly-family weapon modules across different mobility platforms and armament classes; Zmiy Droid 12.7 is the Rovertech Zmiy-platform member of that group.
| Variant | Configuration | Designation notes |
|---|---|---|
 | Tracked 12.7 mm UGV | Uses Droid Box and a Wolly 12.7 combat module on a tracked NUMO platform, rather than the Rovertech Zmiy wheeled platform used by Zmiy Droid 12.7. Sources: Droid TW 12.7 product page |
 | Tracked 40 mm grenade-launcher UGV | Uses Droid Box with a Wolly 40 combat module and 40 mm grenade launcher, placing it in the same DevDroid ground-robot line but in a different armament branch. Sources: DevDroid Droid NW 40 catalog page |
The clearest catalog relationship is the shared control stack that ties the platform, weapon station, cameras, and communications together.
