+Slave_id of each neuron is incremented from 1 and set rqt.  
+ID of servo motors connected to the same neuron is incremented from 1 for joints and gimbals, in that order.  
+The valie of each ID in the Servo.yaml is incremented from 0 starting from the servo with ID 1 connected to neuron with slave_id 1.
