BasicRelativePosition

Measure relative position vector (same as Sensors.RelativePosition, but frame_resolve is not conditional and must be connected)

CONNECTORS
CLOSE ALL
NameTypeDescription
frame_aFrame_aCoordinate system a (measurement is between frame_a and frame_b)
frame_bFrame_bCoordinate system b (measurement is between frame_a and frame_b)
frame_resolveFrame_resolveCoordinate system in which vector is optionally resolved
r_relRealOutput[3]Relative position vector frame_b.r_0 - frame_a.r_0 resolved in frame defined by resolveInFrame
PARAMETERS
NameTypeDefault ValueDescription

USED IN COMPONENTS
Modelica.Mechanics.MultiBody.Sensors.RelativePosition
