Rover

Your starter expedition vehicle for driving, scanning, and mining. The bare chassis does nothing on its own; every ability comes from the modules mounted in its three fixed slots (Nav, Sonar, and Drill function modules only, never containers).

Stats: Energy 100 Wh (sealed, integrated) · Stockpile 10 units (mixed, integrated hold)

How to obtain: Requires the Rover Chassis research (Pressure 0.11). Buy from the Shop for 2,000 cr.

Access: self / get_component(id) · Like every component, exposes .id and .name.

Status and power

.status()

Current physical activity, read fresh on each call. An idle Rover may still have a script running or a job assigned.

Returns: One of "idle" / "moving" / "stranded" / "scanning" / "surveying" / "drilling" / "discarding" / "constructing" / "transferring" / "charging" / "queued" / "being_rescued"

.battery

Charge remaining: level() 0-1 fraction, wh() raw watt-hours, capacity() the 100 Wh max. Below 0.1 you are close to getting stranded; charging_station.dispatch_rescue() can fetch you, but it is slow. holders() returns an empty list (sealed rig). See Battery (Vehicle).

.is_being_rescued()

True while a Vehicle Charging Station rescue drone is actively recovering this Rover. Pause movement or mining scripts even if the battery has started rising.

Returns: Boolean

.rescue_status()

Rescue mission phase: "none", "outbound", "charging", or "returning".

Returns: String

Capability modules

.nav

Drives the Rover: self.nav.set_target(x, y) returns immediately and the Rover keeps driving while the script runs. Call self.nav.brake() before mining, scanning, surveying, or transferring cargo. The Rover stops and clears its route if the script stops, ends, or errors. Requires a mounted Nav Module.

.sonar

self.sonar.scan() finds nearby sites; self.sonar.survey(site) reveals details such as mineral hardness, purity, or vent output. The script pauses while the sonar works. Requires a mounted Sonar Module.

.drill

self.drill.mine() extracts one mineral unit from the surveyed site under the Rover. The vehicle must be stationary with enough cargo space and power. Requires a mounted Drill Module.

Cargo and freight

.cargo

The integrated hold: count() total units across every item and property variant, capacity() is 10, full() is True at capacity (check before loading or drilling). racks() is empty because the hold is integrated. self.cargo.discard(0) permanently jettisons the whole hold and takes 1 hour when cargo is present. See Cargo.

.input

Loads cargo from Inventory at home, local storage at outposts, field-extractor stockpiles, or a nearby stopped cargo vehicle (both stopped, in service range). Requires Auto Feeders. See VehicleInputSlot.

.output

Unloads cargo to Inventory, a Storage Bin, a Warehouse, or a nearby stopped cargo vehicle (both stopped within ~2 m). Inventory freight is physically available only while parked at home. Requires Auto Feeders research. See OutputSlot.

Hardware service

.modules()

List of MountSlot, one per chassis slot. Each has .index, .type (which modules fit), .module_id (mounted id or None), .internal_items (empty on the Rover’s function slots). Call before mount(...) to find an empty slot and verify the slot type accepts the module.

Returns: List of MountSlot

.mount(slot_index, item_id) `SELF ONLY`

Request a hardware service order from Inventory: self.mount(0, "nav_module"). The Rover must be inside a founded outpost service area. Biological field modules are drone-only.

Returns: ActionResult · Outcomes: "ok" / "not_at_service_point" / "locked" / "item_not_in_inventory" / "unknown_module" / "slot_not_compatible" / "slot_occupied" / "invalid_slot" / "capability_already_mounted"

.unmount(slot_index) `SELF ONLY`

Return the module at slot_index to Inventory. Requires a founded outpost service area; container modules must be empty.

Returns: ActionResult · Outcomes: "ok" / "not_at_service_point" / "slot_empty" / "invalid_slot" / "holder_not_empty" / "inventory_full"

.install(…) / .uninstall(…) `SELF ONLY`

Present in the API but not used on the Rover: its fixed slots only accept Nav, Sonar, and Drill function modules, never containers. See Pioneer for the modular version. Calling them returns the same ActionResult outcome sets as on Pioneer (rejections such as "not_container").
