There is no battery level indicator on the original KUBO Coding Single Set robot, however the lights in KUBO’s eyes will show red when the battery is low, or will not light up at all if the battery is flat. Red lights also indicate an error in the code.

If you have the more recent KUBO Coding Starter Set (1030) the robot battery level is indicated when you first place the head onto the KUBO body.
Green at start means KUBO is 100% charged.
Yellow at start means KUBO is max 60% and min 20% charged
Red at start means KUBO is less than 20% charged. When the red light starts to blink KUBO is about to lose all power and must be recharged.
