(In this way it mimics many joysticks.) The translation speed input ranges from -100 to 100, where -100 requests maximum backwards speed, and 100 requests maximum forward speed, 0 requests no translational speed, and values in between request a linear percentage of the maximum. Similarly, rotation speed input ranges from -100 to 100, where -100 indicates maximum rightwards or clockwise rotation, 100 indicates maximum leftwards or counter-clockwise rotation, 0 requests no rotation, and values in between request a linear percentage of the maximum. The throttle input scales the other speed, and ranges from 0 (no motion) to 100 (maximum motion). Seperate objects (e.g. ArRatioInputKeydrive, ArRatioInputJoydrive, ArRAtionInputRobotJoydrive) are used to provide input. When this action is activated it resets all its input ratios to 0 (including throttle). Configuration parameters are used to map the maximum ratios to actual robot speeds. These are set be default to the robot's maximum configured velocities at startup but you can override them with ArConfig parameters (and call addToConfig()) or setParameters(). @see ArRatioInputKeydrive @see ArRatioInputJoydrive @see ArRatioInputRobotJoydrive **/ class ArActionRatioInput : public ArAction { public: /// Constructor AREXPORT ArActionRatioInput(const char *name = "RatioInput"); /// Destructor AREXPORT virtual ~ArActionRatioInput(); /// Set ratios AREXPORT void setRatios(double transRatio, double rotRatio, double throttleRatio, double latRatio = 0); /// Sets the trans ratio (from -100 (full backwards) to 100 (full forwards) AREXPORT void setTransRatio(double transRatio); /// Sets the rot ratio (from -100 (full right) to 100 (full left) AREXPORT void setRotRatio(double rotRatio); /// Sets the lat ratio (from -100 (one way) to 100 (the other)) AREXPORT void setLatRatio(double latRatio); /// Sets the throttle ratio (from 0 (stopped) to 100 (full throttle) AREXPORT void setThrottleRatio(double throttleRatio); /// Gets the trans ratio (from -100 (full backwards) to 100 (full forwards) double getTransRatio(void) { return myTransRatio; } /// Gets the rot ratio (from -100 (full right) to 100 (full left) double getRotRatio(void) { return myRotRatio; } /// Gets the throttle ratio (from 0 (stopped) to 100 (full throttle) double getThrottleRatio(void) { return myThrottleRatio; } /// Adds a callback that is called from this actions fire call AREXPORT void addFireCallback(int priority, ArFunctor *functor); /// Removes a callback that was called from this actions fire callback AREXPORT void remFireCallback(ArFunctor *functor); /// Adds a callback that is called when this action is activated AREXPORT void addActivateCallback(ArFunctor *functor, ArListPos::Pos position = ArListPos::LAST); /// Removes a callback that was called when this action is activated AREXPORT void remActivateCallback(ArFunctor *functor); /// Adds a callback that is called when this action is deactivated AREXPORT void addDeactivateCallback(ArFunctor *functor, ArListPos::Pos position = ArListPos::LAST); /// Removes a callback that was called when this action is deactivated AREXPORT void remDeactivateCallback(ArFunctor *functor); /// Sets the parameters AREXPORT void setParameters(double fullThrottleForwards, double fullThrottleBackwards, double rotAtFullForwards, double rotAtFullBackwards, double rotAtStopped, double latAtFullForwards = 0, double latAtFullBackwards = 0, double latAtStopped = 0); /// Adds to a section in a config AREXPORT void addToConfig(ArConfig *config, const char *section); AREXPORT virtual ArActionDesired *fire(ArActionDesired currentDesired); AREXPORT virtual ArActionDesired *getDesired(void) { return &myDesired; } #ifndef SWIG AREXPORT virtual const ArActionDesired *getDesired(void) const { return &myDesired; } #endif AREXPORT virtual void activate(void); AREXPORT virtual void deactivate(void); protected: std::multimap myFireCallbacks; std::list myActivateCallbacks; std::list myDeactivateCallbacks; // if we're printing extra information or not bool myPrinting; double myTransDeadZone; double myRotDeadZone; double myLatDeadZone; double myFullThrottleForwards; double myFullThrottleBackwards; double myRotAtFullForwards; double myRotAtFullBackwards; double myRotAtStopped; double myLatAtFullForwards; double myLatAtFullBackwards; double myLatAtStopped; double myTransRatio; double myRotRatio; double myThrottleRatio; double myLatRatio; ArActionDesired myDesired; }; #endif // ARACTIONSTOP_H
