Proximity
Proximity sensor between two frames.
Description
Connections
Parameters
The equations for the Proximity component are given below.
Distance:
, is the relative displacement vector.
The distance () is calculated based on the and parameters:
Trigger:
The output signal, , becomes true when:

Units
When checked (true) the distance is calculated along the selected axis of frame_a.
useAxis
1e-3
[m]
Distance threshold between frame_a and frame_b to trigger the sensor.
delta
[1,0,0]
Unit vector (in frame_a) for distance calculation.
e_axis
When checked (true) the output will remain true after the first trigger. When unchecked (false) the output turns to false as soon as the distance between the frames becomes greater than the given threshold ().
hold
When checked (true) an input is enabled to reset the sensor.
