This kit does not charge, rather it operates only while in direct light. Because the solar panel is small, it can require a good amount of energy for sufficient output. We kindly recommend trying one of the following: (Outdoors) Direct light from the sun (indirect or cloud-covered sunlight will not work). (Indoors) Direct light from an incandescent bulb (not an LED or an energy saver bulb).

Q: What's the average size of the robots once complete?

Thank you for your question. Each robot is about 3.25 inches tall.

Q: do these robots work with artificial light? Could you play with them at night in a well-lit room?

Thank you for your question. The solar panel can be powered either by direct light from an incandescent bulb (not an LED or Energy saver bulbs) or direct sunlight.
