   Sample source code of Controller.cpp

#include "Controller.h"
	create2 = iRobotCreate2::getInstance();
	timer = Timer::getInstance();
	create2->safeMode();	// initial entry action
	create2->drive(0,0);	// initial entry action

void Controller::transition(Event event){
	case Controller::Wait:
		if((create2->getSensor()->bumpsWheeldrops&1) && ChangeBumperRight==event){
			controller_state = Controller::Forward;
			create2->drive(100,0);	// entry action
			create2->setNextDistance(200);	// entry action
	case Controller::Forward:
			controller_state = Controller::Turn;
			create2->drive(100,-1);	// entry action
			create2->setNextAngle(-180);	// entry action
	case Controller::Turn:
			controller_state = Controller::Wait;
			create2->safeMode();	// entry action
			create2->drive(0,0);	// entry action
