The vehicles.xml configuration file contains configuration for the vehicles in the simulation.

The "vehicle" element defines a type of vehicle. Each vehicle must have a unique "type" attribute that is used to refer to it in other configuration files. Vehicles have the following child elements:

• fuel-efficiency: This is the fuel efficiency (km/kg) of the vehicle. Rovers currently use methane as fuel. This is a required element.


• base-speed: This is the normal top speed (km/hr) of the vehicle. This is a required element.


• empty-mass: This is the mass (kg) of the vehicle when it is unloaded. This is a required element.


• crew-size: This is the maximum number of people the vehicle can hold. This is a required element.


• cargo: This is the cargo capacity list for the vehicle. The "total-capacity" element is the total mass (kg) of cargo the vehicle can hold. Each "capacity" element has a "resource" attribute that must be a valid resource (see resources.xml). The "value" attribute is the mass (kg) of that resource the vehicle can hold.


• sickbay: This is the vehicle's sickbay. The "tech-level" attribute is the treatment technology level of the sickbay (see "conf/tech_level.txt"). The "beds" attribute is the number of beds in the sickbay. This is an optional element and its absence means that the vehicle doesn't have a sickbay.


• lab: This is the vehicle's laboratory. The "tech-level" attribute is the technology level of the laboratory (see "conf/tech_level.txt"). There is a child element for each technology speciality of the lab. The "tech-speciality" elements must have a value of one of the currently supported research areas: "Areology", "Botany", "Materials Science" or "Medicine". This element is optional and its absence indicates that the vehicle doesn't have a laboratory.

The "rover-name-list" element is a list of rover names that is randomly selected from when rovers are created for the simulation.

Each "rover-name" element must have a unique "value" attribute.
