Learn KUKA-KRL-PROPRIETARY with Real Code Examples

KRL is designed specifically for KUKA robots, enabling precise motion control and robot task programming.

Supports modular procedures, conditional logic, loops, and I/O operations for complex automation tasks.

Used in automotive assembly, material handling, welding, packaging, and other industrial robotics applications.

Integrates with KUKA WorkVisual and KUKA robots’ controllers for deployment and monitoring.

Provides motion commands, data handling, and robot configuration instructions in a structured, readable format.

POS and E6POS data types for positions and orientations

PTP (Point-to-Point) and LIN (Linear) motion instructions

IF, WHILE, FOR statements for structured programming

I/O read/write and digital/analog integration

External axes handling and synchronized motion support

DEF routine - main program entry point

PROC - reusable procedure block

POS - simple Cartesian position

E6POS - Cartesian position with orientation and external axes

I/O instruction - read/write signals to devices

Main DEF routines

PROC subroutines and function libraries

POS/E6POS position definitions

I/O configuration for digital and analog signals

Robot controller project configuration in WorkVisual

Define main DEF routine

Create modular PROC subroutines for repeated tasks

Specify robot positions with POS/E6POS data types

Integrate I/O operations for sensors and actuators

Simulate, debug, and deploy program to robot controller

Beginner: simple point-to-point movements

Intermediate: linear motions and basic loops

Advanced: synchronized motion with external axes

Architect: full factory cell automation with optimized robot paths

KRL vs TP Programming: KRL offers full language control, TP is teach pendant-based

KRL vs RAPID (ABB): both provide structured robot programming, syntax differs

KRL vs FANUC KAREL: KRL is KUKA-specific, KAREL is FANUC-specific

KRL vs PLC control: KRL handles precise robot motion, PLC manages broader process logic

KRL vs ROS/ROS2: ROS is open-source and multi-platform, KRL is proprietary for KUKA robots
