The Main Idea
Every time when you go to the library, looking for a book, you pass from one book to another, pull out each book and read the back cover. This is exactly the action we decided to change – Instead of pulling out the book you just press on it and it moves a bit out of the shelf. Instead of reading the back cover the book whispers it to you.
Planning and Modeling
Our mechanical-robot library based on two major engines. One is a DC engine to move back and forwards and the other is a servo engine that controls the “arm” that serves you the book. The big issue in this project was: How this machine know which book was pushed by a reader? which book shall whisperer?
Finally our solution was: if the books at the library is already in an alphabetical order, it means that every individual book has it’s own place on the shelf. So, we maped the back of the shelf with copper blocks, and strait behind each book, this block located. Then, we installed a reader-head (like in a phono needle) on the arm and then we can count the index of the current book faces the arm.
