Learn FANUC-TP-KAREL with Real Code Examples
Updated Nov 27, 2025
Explain
TP allows operators to program robots interactively using the teach pendant interface.
Karel provides a procedural programming language for writing sophisticated robot programs.
Supports motion commands, I/O operations, and process control.
Enables integration with sensors, conveyors, and other automation equipment.
Widely used in manufacturing, CNC, and industrial automation applications.
