(Concept Enemy/weapon) Grenade Drone

[Raileks]

Appearance - (Im a terrible artist) Take a laser turret and suspend it gyroscopically between two half shells that spin to function as the device's wheels.  Of the turret only the red "eye" is visible in a dark crevice between the wheels.  What your're left with is a device that looks alot like a pokeball with roughly the same size and shape.

 

Function - The device is thrown by Corprus engineers like a grenade.  When it lands it immediatley targets an enemy and will chase and shoot them until destroyed.  It maneuvers by alternating rotation between its left and right shell but has no capacity to jump without an incline and can be foiled by stairs. Its small size and high speed make it a difficult target to hit but its only about as durable as a camera.  Its fires long 2 second laser streams that are rarely deadly for a warframe but can make it impossible to find a safe place to regen shields. When destroyed they explode on anything nearby.
