#include <ArActionTriangleDriveTo.h>
Inheritance diagram for ArActionTriangleDriveTo:
This action uses ArLineFinder to find continuous "lines" in laser range finder data that meet at an angle, forming the point of a triangular shape, towards which the robot is driven and aligned. If an ArLineFinder object is not given in the constructor, then it will search for an ArRangeDevice on the ArRobot with a name "laser" and create its own ArLineFinder object using that range device.
The parameters describing the shape of the triangle target may be set with setTriangleParams(). The default values are for a trianrgle target consisting of two lines of at least 254 mm. meeting at a 135 degree angle. This is the shape of the triangular target on docking stations. Targets also may easily be constructed out of any material well-sensed by the SICK Laser, such as wood, cardboard, or metal.
If setTwoStageApproach() is called with true (default) it will first drive to a half meter away from the desired spot (distFromVertex from the point of the vertex along the bisection of the angle between segments) and then after it reachs that point it will turn in towards the vertex and drive to the final spot. If setTwoStageApproach() is called with false it'll just drive to the final spot. It will stop at closeDist away unless a large turn is required where it'll stop 2 * closeDist away. It drives in at the speed given in the constructor. If the robot is closer to the vertex than it should be for the approach it'll skip the approach, if the robot is closer to the vertex than to the final spot it will back up (if its facing away from the vertex it won't see the vertex).
If you want the action to drive straight to the vertex instead of to a point in front of it call setGotoVertex() with a true argument... It will no longer do this if finalDistFromVertex is 0... you would do this if you want to drive until a bumper is hit for instance.
If you want the action to position using the front of the robot then use setPositionFront().
