External Input For Position Latch and Vision Trigger
Adept MV Controller User’s Guide, Rev C 171
Combined Vision Trigger and Position Latch (“Vision in the Loop”)
An RS-170 video camera operates at 30 frames per second. When the Vision system
receives an External Trigger, it will normally have to wait until the start of the next frame
before it can capture another picture. This can therefore involve a delay of up to 33 ms
(milliseconds). The Adept system allows for a “delayed latch”, where the External Trigger
is used to signal a picture to be taken by the optional AdeptVision system, and then the
AdeptVision system signals the position of the robot or conveyor belt to be latched,
synchronized to the exact moment that the vision picture is captured. This feature is
especially useful when the camera is mounted on a moving robot, or the camera is
viewing an object on a moving conveyor belt. See the AdeptVision VME User's Guide for
details of the Vision Trigger.
