Zumi is a programmable, self-driving car designed to promote coding and learning about AI. It is a small, wireless car that can be programmed using block-based coding on a computer or tablet. The car can be programmed to drive autonomously, recognize objects, and perform other actions based on the sequence of code that is created by the user.

Zumi is useful for promoting coding skills and learning about AI because it provides a fun and engaging way for children to learn about programming concepts and the basics of AI. It promotes creativity and imagination while also developing logical reasoning and critical thinking skills.

In a public library setting, Zumi can be used in a variety of ways to engage children in hands-on learning experiences related to programming and coding. Here are a few possible ways that Zumi could be used in a library:

1. Workshops and Classes: The library can offer workshops or classes on how to use Zumi, which can be open to all ages or targeted to specific age groups, such as elementary school children or teenagers. These workshops can cover topics such as programming, logic, and the basics of AI and machine learning.
2. Drop-in Activities: The library can offer drop-in activities where children can explore and play with Zumi at their own pace. This can be a fun and engaging way to promote learning and creativity while also providing a safe and welcoming space for children to spend time at the library.
3. Group Activities: The library can host group activities where children work together to program and control Zumi cars. This can be a fun and engaging way to teach teamwork and collaboration, as well as programming and problem-solving skills.

Some of the things that can be done with Zumi include:

1. Self-Driving: Zumi can be programmed to drive autonomously using sensors that detect obstacles and road features. This promotes learning about the basics of self-driving cars and the technology behind them.
2. Object Recognition: Zumi can be programmed to recognize objects using computer vision and machine learning algorithms. This promotes learning about the basics of AI and machine learning.
3. Line Following: Zumi can be programmed to follow a line on the ground using sensors that detect the contrast between the line and the surface.
4. Remote Control: Zumi can also be controlled using a remote control feature that allows users to drive the car and perform actions using a smartphone or tablet.

Zumi teaches about self-driving AI cars by allowing users to program the car to drive autonomously using sensors and computer vision algorithms. This provides a hands-on way to learn about the technology behind self-driving cars and the basics of AI and machine learning. Users can also experiment with different programming techniques to improve the performance of the self-driving algorithms and learn about the challenges of developing autonomous vehicles.

Overall, Zumi is a great tool for engaging library patrons in hands-on, creative learning experiences that promote programming and coding skills and encourage imagination and exploration. The library can work with educators or STEM specialists to develop programming or curriculum around Zumi, and can tailor the activities to meet the needs and interests of the library's patrons.
