KAREL is a programming language used to control FANUC robots. It's based on Pascal and designed to be easy to learn and use. This guide introduces the basic syntax elements of KAREL you need to write programs for FANUC robots.
1. Program structure
Every KAREL program starts with a declaration of the program name and ends with an END statement.
2. Comments
Comments in KAREL are written with -- and are ignored by the compiler.
3. Variables and data types
KAREL supports several basic data types:
INTEGER– integersREAL– floating-point numbersBOOLEAN– Boolean values (TRUE or FALSE)STRING– strings
4. Operators
- Arithmetic: +, -, *, /
- Logical: AND, OR, NOT
- Comparison: =, <>, <, >, <=, >=
5. Conditional statements
KAREL uses IF and CASE for conditional checks.
6. Loops
KAREL supports FOR, WHILE and REPEAT loops.
7. Procedures and functions
KAREL lets you define procedures and functions so code can be reused.
8. Working with the robot
KAREL provides special commands for controlling the robot, such as motion, reading sensors and more.
