Constructor Detail

ScribblerBattery

public ScribblerBattery()

Construct a new ScribblerLineSensor.

Method Detail

startUp

public void startUp()

Perform any startup operations for the device. For example, storing a gripper, centering a PTZ or zeroing a dead reckoning device. The implementation provided by this class sets up some timing information necessary for computing sensor read rate statistics and starts the auto read timer if getAutoRead returns true. Subclasses that have their own start up requirements should override this method but should invoke super.startUp() to ensure that the statistics are computed correctly.

The Robot base class invokes this method once in addSensor or addEffector just before the Device is added to the Robot. The Robot will be alive when this method is invoked so it may send commands to the robot. If there are critical problems completing the startUp then this method should throw a RobotCommunicationException.

Overrides:

startUp in class Device

freeze

public void freeze()

This method does nothing. There is nothing to freeze for the line sensor.

Specified by:

freeze in class Device

readStateFromRobot

public void readStateFromRobot()

Send a message to the Scribbler to read the battery voltage and update the values of this sensor.

Specified by:

readStateFromRobot in class Device

getBatteryVoltage

public double getBatteryVoltage()

Get the current voltage of the Scribbler's battery.

Returns:

the battery voltage.

createGUIObjects

protected DeviceDisplay[] createGUIObjects()

Get the GUI for the ScribblerBattery.

Specified by:

createGUIObjects in class Device

Returns:

the GUI.
