RoboDK tools for simulating and programming industrial robots (implements the RoboDK API)

Project description


The RoboDK package implements the RoboDK API for Python.

This package allows you to interact with RoboDK software for simulation and programming industrial robots. With the RoboDK API for Python it is possible to simulate and program any industrial robot using Python programming language. The RoboDK API provides an alternative to using vendor-specific programming languages.

While RoboDK’s graphical user interface can be used to create programs, it is possible to extend the robot controller limitations by using a universal programming language such as Python.

The RoboDK package includes the following 2 modules:

  • The robolink module is the link between RoboDK and Python. Any item from the RoboDK item tree can be retrieved. Items are represented by the object Item. An item can be a robot, a reference frame, a tool, an object or a specific project.
  • The robodk module is a robotics toolbox for Python, inspired from Peter Corke’s Robotics Toolbox:

The following page provides an overview of the RoboDK API for Python:

RoboDK can be used for a wide range of applications, such as 3D printing, robot machining, synchronizing multiple robots, pick and place.

How to install


pip install robodk


RoboDK must be installed to use the Robolink module: * RoboDK Simulation Software:

The Python API can be used with a free RoboDK license.


The following script shows an example that uses the RoboDK package for robot simulation and offline programming:

from robolink import *    # RoboDK's API
from robodk import *      # Math toolbox for robots

# Start the RoboDK API:
RDK = Robolink()

# Get the robot item by name:
robot = RDK.Item('Fanuc LR Mate 200iD', ITEM_TYPE_ROBOT)

# Get the reference target by name:
target = RDK.Item('Target 1')
target_pose = target.Pose()
xyz_ref = target_pose.Pos()

# Move the robot to the reference point:

# Draw a hexagon around the reference target:
for i in range(7):
    ang = i*2*pi/6 #ang = 0, 60, 120, ..., 360

    # Calculate the new position around the reference:
    x = xyz_ref[0] + R*cos(ang) # new X coordinate
    y = xyz_ref[1] + R*sin(ang) # new Y coordinate
    z = xyz_ref[2]              # new Z coordinate

    # Move to the new target:

# Trigger a program call at the end of the movement

# Move back to the reference target:

The same script used for simulation can be used for robot programming offline. This means a program will be automatically generated for your robot controller to reproduce the movements on the robot. RoboDK supports a large number of robot controllers and it is easy to include compatibility for new robot controllers using Post Processors.

App loader Plug-In

Once you have a script working in Python you can easily set it up as an App using the App loader plug-in. RoboDK Apps allow you to customize the RoboDK software environment for simulation and offline programming. RoboDK Apps can be easily distributed for production. More information here:

Linting (source-code checker)

Pylint is a source-code, bug and quality checker for Python programming. Pylint is integrated by default when using RoboDK’s default settings (VScode/VScodium text editor).

If you prefer using other text editors you can use the pylint_robodk module with Pylint for linting. The following argument must be passed to pylint to activate this feature:

  • –load-plugins=pylint_robodk
