Epson 5 RobotU Result

RobotU Result

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.
