Detailed Description

This action will use the joystick for input to drive the robot.

This class creates its own ArJoyHandler to get input from the joystick. Then it will scale the speed between 0 and the given max for velocity and turning, up and down on the joystick go forwards/backwards while right and left go right and left. You must press in one of the two joystick buttons for the class to pay attention to the joystick.

Note:

The joystick does not save calibration information, so you must calibrate the joystick before each time you use it. To do this, press the button for at least a half a second while the joystick is in the middle. Then let go of the button and hold the joystick in the upper left for at least a half second and then in the lower right corner for at least a half second.

Examples:

actionGroupExample.cpp, gpsRobotTaskExample.cpp, gripperExample.cpp, gyroExample.cpp, and teleopActionsExample.cpp.

Constructor & Destructor Documentation

ArActionJoydrive::ArActionJoydrive (  const char *  name = "joydrive", double  transVelMax = 400, double  turnAmountMax = 15, bool  stopIfNoButtonPressed = true, bool  useOSCalForJoystick = true )

Constructor. This action is for driving around the robot with a joystick, you must hold in a button on the joystick and then lean the joytsick over to have it drive. You may need to calibrate the joystick for it to work right, for details about this see ArJoyHandler. If the Aria static class already has a joyhandler this class will use that otherwise it'll make and initialize one and use that (setting it in the Aria class) Parameters: name  the name of this action transVelMax  the maximum velocity the joydrive action will go, it reachs this when the joystick is all the way forwards turnAmountMax  the maximum amount the joydrive action will turn, it reachs this when the joystick is all the way forwards stopIfNoButtonPressed  if this is true and there is a joystick and no button is pressed, the action will have the robot stop... otherwise it'll do nothing (letting lower priority actions fire) useOSCalForJoystick  If true, then the existing OS calibration for the joystick will be used, otherwise our own autocalibration will be used. Default is true. See also: ArJoyHandler::setUseOSCal()
