After initially making LArRE we received lots of requests and ideas from the community for extra functionality. Originally, we kept LArRE's scope and capabilities limited, so we could prototype properly in a quick and maintainable manner. Now, with all the positive feedback, instead of making one complicated device that does everything we decided to split these functions up into specialized versions. There are four new arms that replace the existing one.

Each arm is constructed by placing the corresponding dock. The new docks differ from the old LArRE arm in that arms can move off the rail into the dock, allowing other arms constructed on the same rail and move freely past.

New LArRE Arms and Docks

Cargo

The cargo arm is made to interact with slots of devices and structures and is useful for things like changing filters, pulling items from lockers, and other slot-based tasks.

A key thing to note with the cargo arm is the concept of the target slot. This is a special slot targets a slot on the target structure and will be what the item that is picked up when the arm is activated. The target slot can be set by a dial on the dock, or by logic.

Collector

The collector arm acts as a vacuum cleaner when set to inwards, sucking up loose nearby items, and when set to outward will eject the items.

Hydroponics

The hydroponics arm can plant and harvest plants as well as place fertiliser into plant trays. It has an additional hopper slot which will feed items into the 'hand' slot when the hand slot is empty. Harvesting a different plant while the hand slot is full will be possible if the hopper slot is empty. The full behaviour of these two slots is described in the Stationpedia.

Atmospheric

The atmospherics arm has a storage canister and can pump gas in or out. It has a filter slot so you can selectively extract gasses from a space.

When activated over a passive vent it will 'dock' with the passive vent and pump in or out of it, depending on the mode of the arm is in.

Bypass

The bypass dock does not have an arm associated with it but allows for any arm to move off the main rail to allow other arms to move past.

Rail Network Changes

New Rail Pieces

LArRE rails can now operate in all axis. This means arms can travel on walls facing sideways, and on floors facing upwards, etc. Several new pieces such as inner and outer corners, and quarter corkscrew pieces allow a full range of mobility.

Multi Arm Rails

Rail network logic also has some new rules. Multiple docks can be built on a single linear rail, to allow multipurpose tracks. Though arms will collide with one another, so it's up the player to use the above-mentioned dock changes, and bypass docks to avoid traffic jams. Rails also now support being connected in a loop. Any LArRE Attempting to navigate to a location on a loop will take the path with the least stations.

Dock Restriction

One new restriction is the inability for LArRE to interact with anything directly under its dock, as activate will attempt to trigger a dock/undock. This was required to keep LArRE's operation simple, without forcing every model to have an additional control.

---

Proxy Slot Reading

Since LArRE arms perform contextual actions on the devices they are over, they have the ability to potentially operate on multiple slots. We've added the concept of proxy slots to allow players to know the details of the slot they are about to interact with. These are listed in the Stationpedia as slots with the type "proxy", and they allow logic systems to point towards a static slot irrespective of the arm's internal variables changing what slot is focused. An example of this is the Cargo LArRE slot #255, which will show the slot of what his slot index dial is pointing towards.
