Updated Nov 27, 2025
Explain
URScript is a high-level, interpreted language designed for industrial robotic control.
Supports motion commands, I/O manipulation, and tool control.
Can be used directly on UR robots or via external controllers through network interfaces.
Includes functions for path planning, speed/acceleration control, and robot state monitoring.
Widely used in automation, pick-and-place, collaborative robotics, and research environments.
Core Features
Joint-space and Cartesian-space movement commands
Waypoints, speed, and acceleration control
Loops, conditionals, and function definitions
Payload and tool control
Network communication for external program control
Basic Concepts Overview
movel(pose) - linear movement in Cartesian space
movej(joint_positions) - joint-space movement
set_digital_out(pin, state) - control digital output
get_actual_tcp_pose() - read current tool position
sleep(seconds) - pause execution for timing
Project Structure
Single URScript (.script) file or multiple scripts
Define functions for repetitive tasks
Include initialization and shutdown routines
Use global variables for shared data
Optional network scripts for external control
Building Workflow
Define robot motion and I/O requirements
Write URScript program with movement commands
Test individual commands via Polyscope
Combine commands into loops and functions
Run full program with safety checks
Difficulty Use Cases
Beginner: simple point-to-point movement
Intermediate: pick-and-place with I/O control
Advanced: integration with sensors and vision
Expert: collaborative operations with humans
Architect: full automation workflow with external systems
Comparisons
URScript vs Polyscope GUI: code-based vs graphical programming
URScript vs Python+UR API: low-level vs high-level control
URScript vs RAPID (ABB) or KRL (KUKA): vendor-specific scripting
URScript vs PLC ladder logic: robot motion vs industrial control
URScript vs ROS nodes: direct robot vs middleware control
