void kobuki::Kobuki::lockDataAccess ( )

Usually you should call the getXXX functions from within slot callbacks connected to this driver's signals. This ensures that data is not overwritten inbetween getXXX calls as it all happens in the serial device's reading thread (aye, convoluted - apologies for the multiple robot and multiple developer adhoc hacking over 4-5 years for hasty demos on pre-kobuki robots. This has generated such wonderful spaghetti ;).

If instead you just want to poll kobuki, then you should lock and unlock the data access around any getXXX calls.

void kobuki::Kobuki::printSigSlotConnections ( ) const

Print a list of all relevant sigslot connections.

This includes both the kobuki driver signals as well as externally connected slots. Useful for when you need to check if any of your connections are dangling (often happens when you typo the name of the sigslots connection).

Definition at line 528 of file kobuki.cpp.

void kobuki::Kobuki::sendCommand ( Command command ) [private]

Send the prepared command to the serial port.

Need to be a bit careful here, because we have no control over how the user is calling this - they may be calling from different threads (this is so for kobuki_node), so we mutex protect it here rather than relying on the user to do so above.

Parameters:

command : prepared command template (see Command's static member functions).

void kobuki::Kobuki::shutdown ( ) [inline]

Gently terminate the worker thread.

Definition at line 101 of file kobuki.hpp.

void kobuki::Kobuki::spin ( )

Performs a scan looking for incoming data packets.

Sits on the device waiting for incoming and then parses it, and signals that an update has occured.

Or, if in simulation, just loopsback the motor devices.

Definition at line 176 of file kobuki.cpp.

void kobuki::Kobuki::unlockDataAccess ( )

Unlock a previously locked data access privilege.

void kobuki::Kobuki::updateOdometry	(	ecl::Pose2D< double > &	pose_update,
		ecl::linear_algebra::Vector3d &	pose_update_rates
	)

Use the current sensor data (encoders and gyro) to calculate an update for the odometry.

This fuses current sensor data with the last updated odometry state to produce the new odometry state. This will be usually done in the slot callback to the stream_data signal.

It is important that this is called every time a data packet is received from the robot.

Parameters:
