My First Robot” is a book for young children (ages 1-3), intended as an introduction to sensory input and output. I created this book to excite children about small electronics and robots.

Using an Arduino, buttons, and an IR sensor, I programmed the robot (named Isbot) to sing a song for its user. When the user gives Isbot a high-five or a low-five (pushes one of the red buttons), Isbot detects their depth (Isbot’s eyes are the IR sensor) and will either sing a song slowly (if they are close) or very quickly (if they are far away). This book gives parents a platform to discuss depth, sound, and touch.
