+#### Excitatory vs inhibitory behaviour
+
+This time when using excitatory behaviour as in the more light the more motor power, 
+the robot will not move without light. While Inhibitory behaviour results in constant movement.
+
+If the right sensor's input correspond to the right motor and the left sensor's input corresponds to the left motor. 
+The robot will move away from the light with excitatory behaviour and towards the light with inhibitory behaviour. 
+
+If we switch what the sensor's input correspond to we observe the opposite behaviour in the two cases.
