The igus® Robot Control software

Programming - simulating - controlling robots free of charge and license-free

igus® Robot Control enables simple and intuitive robot programming and control and an easy entry into automation. Due to the modular design, different robot kinematics can be controlled, e.g. delta robots, linear robots and multi-axis joint robots. The software can be used to simulate the individual movements of the robot on the 3D interface - the robot does not need to be connected for this step.

iRC software overview



PLC interfaces

The PLC interface enables the execution of basic functions and the signalling of states by means of digital inputs and outputs. In addition to the control by a PLC, this interface also allows operation by hardware buttons.
To the SPS Wiki


Digital inputs & outputs

Robot programs can be loaded and started and gripper commands can be sent via digital inputs or global signals. This is useful, for example, if a program is to be selected from a given selection using buttons or the CRI-GSig instruction.
To the I/O Wiki


Modbus TCP/IP

For example, PLCs can send data and instructions to the robot control system and receive status information via the Modbus TCP interface.
To the TCP/IP Wiki


CRI interface

The CRI interface enables complex instructions to be sent and information and settings to be retrieved via the Ethernet interface via TCP/IP. iRC uses this interface to connect to robots with integrated control systems or other instances of iRC.
To the CRI Wiki


Camera interface

The camera interface allows the use of object detection and video cameras. Object detection cameras recognise the position and class of objects and transmit them, optionally with a video image, to the control system. The control system calculates positions in the robot coordinate system from the object positions of the camera. Pure video cameras only deliver images and can therefore only be used to observe the work area, but not for object detection.
To the Wiki



The Cloud interface enables the robot to be monitored via RobotDimension. After activation and login, the robot sends basic status information and camera images to the online service. On the website, the user can list his robots and call up the information.

Project configurations


The installed tool can be specified here. Changing the tool requires reloading the project or restarting the integrated control system. New tools can be defined as a configuration file in the "Data/Tools" directory
To the I/O Wiki

Virtual box

The virtual box settings limit the range of movement of the robot arm. This functionality helps to avoid mechanical damage and simplifies programming according to the application. If a program is executed that violates the virtual box, it is stopped with an error message.

External axes

The robot control system supports up to three additional axes (also called "external axes" in iRC). These can be installed according to the robot axes and configured via the configuration area of iRC.
Go to the External Axes Wiki

Here you can set the robot and logic program, the movement speed (as a percentage of the maximum speed), the playback mode and the reaction to program errors.

Special kinematics

The robot control system can be individually configured for your robot with a digital twin. We configure the inverse kinematics to suit your project business.
special kinematics


axis movement

Axis movements

The Joint command moves the robot to an absolute target position specified in axis coordinates (e.g. axis angle or position of a linear axis). The resulting movement of the TCP is usually a curve and not a straight line.

linear motion

Linear movement

The Linear command moves the robot to an (absolute) target position specified in Cartesian coordinates. The resulting movement of the TCP follows a straight line.

circular movement

Circular movements

The Circular Movement instruction enables movements along a full or partial circle. It is compatible with linear movements, so that the transition from and to linear movements can be smoothed over.



Conditions can be used in if-then-else commands, loops and as termination conditions in movement commands. The conditions can be combinations of digital inputs, global signals, Boolean operations and comparisons.

matrix calculation

Matrix calculation

The grid instructions calculate positions that are aligned with a grid, e.g. as gripping or depositing positions for palletising tasks.



The Relative command allows moving the robot relative to its current position. It can be called up via the menu items under "Action" → "Relative movement".



Subprograms can be called up with the Sub command. The path to the subprogram file is specified under "File name". It is relative to the "Programs" subfolder of the iRC "Data" folder.

variable access

Variables and variable access

Two types of variables are supported in programs for iRC and TinyCtrl: 
  • Numerical variables: these can be used to store integer or floating point numbers. 
  • Position variables: these can be used to store Cartesian positions and joint positions. Whether such a variable is interpreted as a Cartesian position or a joint position depends on the context.
