2. Write the subscriber in the code.

 rospy.Subscriber('/pid_tuning', PidTune, self.set_pid_value )

3. Get the Value and change the Gain values.

 def set_pid_value(self,data):
  	self.kp_x = data.Kp 
  	self.kp_y = data.Kp 
  	self.kp_z = data.Kp
  	
  	self.kd_x =  data.Kd
  	self.kd_y =  data.Kd
  	self.kd_z = data.Kd
  	
  	self.ki_x = data.Ki
  	self.ki_y = data.Ki
  	self.ki_z = data.Ki
