Karel is a term that can refer to two different concepts. However, both of these concepts are related to computer programming and computational thinking.
Firstly, Karel is a programming language and environment specifically designed for beginner programmers to learn the basics of computer programming. It was developed in the 1980s as an educational tool by Richard E. Pattis at Stanford University. Karel is a simple language with a minimal set of commands that allow students to understand fundamental concepts such as sequencing, loops, conditionals, and functions. The language is primarily used to introduce students to algorithmic thinking and problem-solving skills.
Secondly, Karel can also refer to a fictional, simplified robot character created by Richard E. Pattis to teach programming concepts. In this context, Karel represents a robot that lives in a two-dimensional grid-like world, where it can move, turn, pick up or put down objects, and interact with its environment. Students can write programs for Karel to solve various tasks and challenges, which helps them understand the concept of a real-world robot relying on a set of instructions to accomplish specific tasks.
In summary, Karel can be seen as both a programming language/environment and a fictional robot character used in educational settings to introduce individuals to the fundamentals of computer programming and computational thinking.
The name "Karel" has its origins in several languages. In Slavic languages such as Czech and Slovak, "Karel" is a variant of the name "Karl" or "Karlík" which trace back to the Germanic name "Karl" meaning "man" or "free man". The Germanic name "Karl" itself has Old Norse origins from the name "Kári", meaning "curly-haired". It was a popular name among Germanic-speaking populations, and due to the influence of Germanic cultures in Central Europe, it has spread to other languages in the region.
