Grabber

Grabber is a 4/8/16-slot storage. It automatically "steals" any nearby item that is lying on the ground (e.g. was just dropped by a defeated monster). That item is stored inside the Grabber (player can retrieve it at any time).

Grabbers are often used with Farmbeast Harvester Turret, Harvester Turret or Bug Harvester Turret to collect the dropped materials.

List of grabbers

 * Grabber v1 - 4 slots, range 4.
 * Grabber v2 - 8 slots, range 8.
 * Grabber v3 - 16 slots, range 12.

Performance impact
Grabbers frequently scan their surroundings, which may decrease performance if you have many of them.

To avoid lag, you can throttle the Grabber (see Configurable 3-State Cycler for an example) the same way you would throttle an Item Transference Device.
