 * Project name: care-o-bot
 * ROS stack name: cob_drivers
 * ROS package name: cob_base_drive_chain
 * Description: This is a sample implementation of a can-bus with several nodes. In this case it implements the drive-chain of the Care-O-bot3 mobile base. yet, this can be used as template for using the generic_can and canopen_motor packages to implement arbitrary can-setups.

 * Date of creation: Feb 2010
 * ToDo: - Check whether motor status request in "setVelGearRadS" "setMotorTorque" make sense (maybe remove in "CanDriveHarmonica").
 *               - move implementational details (can cmds) of configureElmoRecorder to CanDriveHarmonica (check whether CanDriveItf has to be adapted then)
 *               - Check: what is the iRecordingGap, what is its unit
 *               - Remove Mutex.h search for a Boost lib
