This is a big difference. Dozens of dollars have no artificial intelligence technology at all, nor can they be networked, upgraded and interacted. It's not really an intelligent robot at all. If you want to buy an intelligent robot for your child, you must choose a regular manufacturer, such as Alpha Egg, a subsidiary of Iflytek. In the sales volume of 6 18 this year, a certain east and a certain cat both won the sales champion of the same category. It is worthwhile to spend more money on such products, which can really help children learn.
