Nice project! You pay a LNURL to make a spider robot to move. Payment is split with kid's wallet that will receive some sats and also amazed that his robot is moving. https://twitter.com/blackcoffeebtc/status/1534536348442447873

LNURL is provided in the tweet. Once you pay you receive also a confirmation that the robot is moving. Soon he will put a webcam too. Well done!
