BOLT+ Temperature Warnings

Occasionally, you may see temperature warnings while using the Sphero Edu app with your Sphero BOLT+. Below are the types of warnings, why they happen, and what to do.

Temperature Warning

Because Sphero BOLT+ has a sealed shell, heat can build up inside during certain conditions. This may trigger a temperature warning, even though your robot is still safe to use.

Common causes include:

  • Heavy use of the display (images, animations, text)

  • Extensive motor use (driving)

  • Charging in the cradle

  • High room or outdoor temperatures

  • Direct sunlight or strong light sources

What to do:
Your BOLT+ will keep working normally, but moving it out of direct sunlight or into a cooler space can help prevent further warnings if you plan to keep using it.

Critical Temperature Warning

If heat continues to rise, you may see a critical temperature warning. In this case, your BOLT+ will temporarily disable the display to protect itself.

What to do:

  • Disconnect from your BOLT+ and let it power down.

  • Move it out of direct sunlight and remove it from the charging cradle.

  • Allow about 30 minutes for it to cool. Once cooled, all features will automatically be re-enabled.
