Introducing Robot Library

Over the years, there have been several attempts to teach programming languages to children. Teachers and governments wanted to show children that programming isn't magic, and that simple logic is all that was required. The British Broadcasting Corporation, BBC for short, even went as far as to create its own computer for schools to accompany a television series on computer programming. It was a huge success and was just one of many projects. One of these projects was the Logo programming language.

Most programming languages are mathematical: ...
