RobotU Result

Applies To
Vision Objects: ArcFinder, ArcInspector, Blob, BoxFinder, CodeReader, CornerFinder, Correlation, DefectFinder, Geometric, Line, LineFinder, LineInspector, Polar, Coordinates

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 (error 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 Y, but also the X, and U coordinate positions as well as whether the part was found. See RobotXYU Result.
RobotXYU Result

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.

You can add an offset to the RobotU result by using the RobotUOffset property.

Statistics
For the RobotU Result, the following statistics are available.

RobotUMax, RobotUMean, RobotUMin, RobotUStdDev.

For details on how to use statistics, refer to 9.Using Vision Guide Statistics in the Vision Guide Software manual.
