The Drone/$ will go to the closest entity in the specified Area/$ that matches an (optional) attached Entity Filter/$ in a connected Text/$ widget, and pick it up to be transported.
This includes players, although players can easily escape a Drone/$ by sneaking/$ to dismount. Having said that, being carried around by a flying entity you can control has its upsides...
Experience Orbs
Drones are also able to import Experience Orbs/$ using this widget; the @orb/$ entity filter will match XP orbs. Imported orbs are converted to Memory Essence/$ and stored in the drone's internal tank; you can then use the Liquid Export/$ widget to transfer that to a fluid tank.
Area Limitations
Keep in mind that any Area/$ widgets connected to this widget must have an area type of Box/$; this is the only supported shape. It's possible to create different shapes, though, by using whitelisting/blacklisting of areas.
