This is an issue of the globe not being able to know where to stop exactly.
This could happen due to one of these reasons:
1- Wrong power adapter (please send us a picture of the specifications label on the power supply and let us know if it was plugged directly to the wall or not)
2- Missing or misplaced magnets inside the globe (Please remove the bonnet and take the globe out of the robot then use the attached pictures to know where the magnets are located, bring any metallic object near these areas to test if the magnets are in place and attracting metal or not)
