About the Author

Ziyu Huang works in the technology industry and is a devoted educator and entrepreneur. She is a mom of three kids who are book lovers and question askers, with enquiring minds. Ziyu felt the need to introduce young children to the concept of new technologies, and how these impact our daily lives. She started her first book in the Bob the Bot series and continues to write about new technologies covering artificial intelligence, machine learning, smart homes, urban farming, self-driving smart cars, Virtual Reality, and more. She is hoping that Bob the Bot can be a conversation starter that opens the fun world of technology to young children through reading her book series Bob the Bot.
