Spatial mine droid

Spatial mine droids are a model of battle droids created solely by the Acran weapons facility for use against star fighters.

Design
Spatial mine droids are completely round, have two blue sensors on either side of the head, tough metal armour, a small drill on the bottom for attaching themselves to the hulls on ships, twin blaster cannons above each sensor, thrusters built into the back for mobility and are normally painted in the colours of the Elementa alliance. They are stationed in large numbers at planets they are assigned to protect against enemy threat, and during the time that they are not in use, shut themselves off and act similarly to normal space mines. Their intelligence was limited, enough so that they knew which ships were their own or allied and which ships they could attack. Their tough meant that their speeds were limited but could actually discard it for faster speeds should the situation call for such a need. Despite the great success in the line the problem was that their seismic detonators that were built in could also damage friendly ships and were expensive. A cheaper model was produced with a smaller blast radius although it didn't sell as well as the older model. They saw great action during the Battle of Elem and any surviving mine droids were either decommissioned or reprogrammed to serve the new Republic. Additionally they also had four spider like retractable legs that allowed surface movement in case of meteors or the odd chance that they would actually see use on ground.
