        isOn = true;

}

    

// No default command defined for Conveyor.

void Sweeper::InitDefaultCommand() {}



// Start running the instance with the current state

void Sweeper::run() {

        if( isOn ) {

                if( isIn ) {

                        relay->Set(Relay::kForward);

                }
