TractorMobility¶

simple module TractorMobility

Moves a tractor through a field with a certain number of rows. Since the tractor also moves around the field, the tractor travels the number of rows PLUS one row. Consider the following piece of ascii-art for rows=2.

NOTE: Does not yet support 3-dimensional movement.

Extends¶

Name	Type	Description
MovingMobilityBase	simple module	Abstract base module for mobility models.

Parameters¶

Name	Type	Default value	Description
displayStringTextFormat	string	“p: {position}\nv: {velocity}”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
subjectModule	string	“^”	The module path that determines the subject module, the motion of which this mobility model describes. The default value is the parent module
coordinateSystemModule	string	“”	The module path of the geographic coordinate system module; optional, empty disables geographic conversion (and the {geo_position} directive)
updateDisplayString	bool	true	Enables continuous update of the subject module’s position by modifying its display string
constraintAreaMinX	double	-inf m	The minimum x position of the constraint area. It is unconstrained by default (negative infinity)
constraintAreaMinY	double	-inf m	The minimum y position of the constraint area. It is unconstrained by default (negative infinity)
constraintAreaMinZ	double	-inf m	The minimum z position of the constraint area. It is unconstrained by default (negative infinity)
constraintAreaMaxX	double	inf m	The maximum x position of the constraint area. It is unconstrained by default (positive infinity)
constraintAreaMaxY	double	inf m	The maximum y position of the constraint area. It is unconstrained by default (positive infinity)
constraintAreaMaxZ	double	inf m	The maximum z position of the constraint area. It is unconstrained by default (positive infinity)
updateInterval	double	0.1s	The simulation time interval used to regularly signal mobility state changes and update the display
faceForward	bool	true
speed	double
x1	double
y1	double
x2	double
y2	double
rowCount	int		The number of rows on the field

Properties¶

Name	Value	Description
class	TractorMobility
display	i=block/cogwheel

Signals¶

Name	Type	Unit	Description
mobilityStateChanged	inet::MobilityBase		It works in inet, but not in the extended module in another namespace
