Meaning of ARI LEDs colors and patterns

There are four different LEDs displays in ARI, located on the ears, the microphone (on the front of the robot) and on the back.

Ears

Both ears have the same behaviour and the ARI’s ear LEDs have two default meanings:

  1. yellow and red blinking ears mean that battery level is under 20%. For more details check the battery how-to;

  2. blue and red blinking ears mean that an error on the motors occured.
