RobotU Result
Applies To
Vision Objects: Blob, Correlation, Edge, Geometric, Line, Polar
Description
Returns the U angle of the found part's position in the robot coordinate system.
Usage
VGet Sequence.Object.RobotU [(result)], var
Sequence
Name of a sequence or string variable containing a sequence name.
Object
Name of an object or string variable containing an object name. The object must exist in the
specified sequence.
var
Real variable that will contain the value of the result.
result
Optional result number. If omitted, the result number is the CurrentResult. Used for objects
that return multiple results.
Values
Real value representing in degrees (0 if no calibration).
Remarks
The RobotU result is similar to the Angle result except that the position results are returned with reference
to the robot coordinate system. This means that the RobotU result is suited for robot guidance applications.
However, keep in mind that a special result called the RobotXYU result is most often used for robot
guidance because it returns not only the U, but also the X, and U coordinate positions as well as whether or
not the part was found. See RobotXYU Result for more information.
It should be noted that the RobotU result can only be calculated for vision sequences which have been
calibrated with the robot coordinate system. If no calibration has been assigned to the vision sequence then
the RobotU result will return 0.
Statistics
For the RobotU Result, the following statistics are available. RobotUMax, RobotUMean, RobotUMin,
RobotUStdDev. Please see Statistics in the Vision Guide manual for details about using statistics.
