Understanding and calibrating your robot is important for applications that require precision. These RoboDK Add-ins provide functionality to fully optimize your robot.
Robot calibration is an often unsung hero of automation. People don’t always realize that the precision you can achieve with a robot largely depends on how well the it is calibrated. At RoboDK, some of our most popular features, products, and services are those related to calibration.
There are also various Add-ins available to improve data analysis and calibration in our RoboDK Marketplace. These extend the functionality of RoboDK for specific tasks.
Here are 7 excellent Add-ins for understanding, analyzing, and calibrating your robot:
1. RoboCharts
RoboCharts gives you the tools to graphically analyze your robot’s trajectories and joint usage within RoboDK. This is ideal when you are looking to identify aspects of your robot program you can improve.
Who is the Add-in for?
RoboCharts is especially useful for engineers and programmers who are looking to go deeper into robot data and analysis. It can help you identify inefficiencies and gather data for reporting.
What does it do?
The Add-in provides in-depth graphs of a range of statistics relating to both robot trajectories and joint activity.
Features include:
- Visualization of 3D robot trajectories and 2D projections on XY, XZ, and YZ planes.
- Position tracking over time for accurate trajectory analysis.
- Detailed joint usage metrics, such as joint range, configuration, and distribution over time.
2. Reachability
Reachability helps you preview the reachable tool poses of your robot, allowing you to see the best areas in its workplace to position your task.
Who is the Add-in for?
The Add-in is for anyone who wants to benefit from one of the most useful and under-appreciated tools in robotics: Reachability Analysis…
… although maybe I’m biased when I say that, as my PhD was partly about reachability analysis. But it is an extremely useful technique for fully understanding the capabilities and limitations of your robot.
What does it do?
The Reachability Add-in provides a visual preview of both reachable and unreachable tool poses, helping identify motion limitations quickly and effectively.
Features include:
- Visualization of the robot arm and tool for a clear understanding of reach capacity.
- Highlighting of reachable and unreachable poses for precise motion planning.
- Customizable parameters, including translation and rotation allowances, to tailor reachability analysis to your project needs.

6. Ballbar Tracker
Ballbar Tracker enables you to perform the standard ballbar tracking procedure for robotic calibration, allowing you to measure your robot’s performance and validate its accuracy.
Who is the Add-in for?
The Add-in is ideal when you are looking to verify that your robot achieves the accuracy that you need for a particular application. It is particularly useful if your robot operates in an industry with stringent performance requirements.
What does it do?
Ballbar Tracker allows you to attach a ballbar mechanism to your robot, using its functionality for measuring and analyzing the robot’s operational accuracy.
Features include:
- Attaching and detaching a ballbar in RoboDK via the UI or API for streamlined operation.
- Measuring and recording robot accuracy degradation over time for maintenance planning.
- Generating circular paths and automated measurements, integrating tools like the Renishaw QC20-W ballbar for precision reporting.
- Validating robot accuracy, both with stationary and moving tool center point (TCP) orientation.
