Resolver: The Ultimate Robot Path Planner​

On Monday, May 12th, 2025 we launched Resolver at the Automate Show in Detroit, Michigan and everyone was impressed and excited about it. Some even called it the best robot demo. We could not have developed this amazing product without your input and feedback during our early access period - THANK YOU!

We launched with a ton of new features as you will see in this email, so grab some coffee and read on!

In today's Resolver 2025.1.0 release

• PS Connector integrated as a Viewer
• New cloud UI
• Target offsets
• Robot allocation
• Cartesian interpolation
• PS Connector 1.0.5

PS Connector integrated in PS as a Viewer​

Export directly to Resolver while you continue working in PS
Export and automatically upload, no need to deal with zip files anymore! Continue working in PS while Resolver is processing multiple options in parallel. Select your preferred results based on number of interlock zones and cycle time. Then simply import those results without leaving PS.

---

New Build UI in the cloud​

Visualize compound operations and experience new features
With the new features such as Target Offsets, Robot Allocation, and Cartesian Interpolation, we designed a new Resolver UI that is powerful, yet flexible. After exporting your study, you will see new options at the operation and target levels to fine-tune your query. Download the latest PS Connector to make sure you can access the latest UI.

---

Target Offset​

Let Resolver add approach and depart points for you
To help reduce the amount of engineering at the proposal and design stage, we are happy to introduce Target Offsets. Specify an X, Y, or Z offset with external axis values and apply it to as many points as you want, or all of them. Resolver will use the offsets as approach and depart points when path planning and generating interlocks.

---

Robot Allocation​

Optimize the target-to-robot allocation
For any multirobot application where more than one robot can perform the same task, let Resolver know which robots are allowed to be considered for that operation. Resolver will consider all robots selected and evaluate reachability, paths, and interlocks that result in the optimal target-to-robot allocation. Please note that using this feature expands the number of possible solutions and Resolver should be run longer.

---

Cartesian Interpolation​

Resolver can now plan in cartesian space to generate linear moves
Based on your feedback, we have added support for planning paths in cartesian space, when necessary. Resolver will generate paths that are based on linear moves if possible. If there are collisions or too many singularities, it will revert back to joint space. The interpolation type must be specified in the cloud UI since we are not yet collecting the data directly from PS. This feature is coming soon to the PS Connector.

Auto-Tuning on Import​

Smoothing Auto-tuning in minutes!
In our previous release, we acknowledged performance limitations with the auto-tuning of smoothing parameters during import. Since then, our team has been hard at work—and we're excited to share the results.

With this release, we're introducing significant improvements to API efficiency and two powerful new import modes: FAST and OPTIMAL.

FAST Mode​

Need speed? FAST mode quickly imports paths using default conversion values tailored to your selected robot OEM. If scraping collisions are detected, it smartly adjusts to a FINE smoothing level. This mode is ideal for rapid validation when your priority is speed—just note that in high-collision scenarios, some smoothing may be less than ideal.

OPTIMAL Mode​

Looking for precision? OPTIMAL mode performs an in-depth analysis to find the highest possible smoothing value for each via—based on your allowed values—delivered through our Resolver engine. We've reengineered the API interactions behind the scenes, significantly reducing optimization time while delivering the highest-quality path smoothing available. While the time required still scales with the number of smoothing options per via, the results speak for themselves: ultra-smooth, OEM-optimized paths.

Reachability Report​

Quickly check check reachability of all targets and download report Manually jumping robots to each target only provides limited reachability information and is also so boring. Now you can save a ton of engineering time by letting Resolver do the reachability check for you. Resolver will check if robots are able to reach their assigned targets by generating actual motion paths. In minutes it will put the information in a nice table that can be downloaded in CSV format for you to use elsewhere in your planning and engineering processes.

The different states displayed on the table are:

• Pending (hourglass): the Engine is calculating reachability.
• Not Reachable (red): the target is not reachable.
• In Collision (yellow): the target is reachable but only through a collision.
• Reachable (green): the target is reachable without collision.

Today's update:

• Challenges we are working on
• Robot vendor-specific smoothing
• PS Connector 0.10.0-beta released

Challenges we are working on​

The performance of some features are not up to our standard
As we continue to innovate and quickly bring new capabilities to help you reduce engineering time, some of the capabilities and features are not delivering the value you have come to expect. As a result, we wanted to let you know we are working to make drastic improvements in the following areas:

Auto-tunning on Import
Issue: Auto-tuning on import with RCS can take minutes to several hours to complete.

What we are doing: We are making the import code faster, introducing fast and optimal tuning options, and allowing the user to set the simulation time interval. We expect these features to be ready shortly.

What this means for you:

• If simulating without RCS, please use auto-tuning. It will take a few minutes.
• If using RCS, know that auto-tuning could take several hours. In the short term, importing without auto-tuning and manually touching up collisions is also an option.

Self-collisions of robots
Issue: We have reports of self-collisions of robots and attachments. The reason for this issue is that no collision rules have been defined. Examples include 1) collisions between a weld gun and the robot and 2) collisions between the weld gun and RTU. Please read the Collision Rules section of the docs for more information.

What we are doing: We are exploring different options to simplify the workflow and validate expected collision sets.

What this means for you:

• Ensure collision sets are defined between robot links and any attachment to the robot.

Optimize Tool Configuration in Rx, Ry, or Rz
Issue: The Optimize Rz functionality is producing sub-optimal results for spot weld applications when targets have robot to part collisions. This happens frequently because the engine is not currently aware that the gun tips can be ignored. Work has already been done to encode ignore collision rules at the targets for the gun tips, but some engine work remains.

What we are doing: We will be disabling this feature in the coming days until the gun tips are properly defined and dealt with in the engine during TCP orientation optimization.

What it means for you:

• If you have an opportunity to optimize the tool rotation, try running both with and without the Optimize Rx, Ry or Rz.

Robot Vendor-Specific Smoothing​

Previously, users could only specify 5 (mm) smoothing values. Now, we've expanded support to include all Robot-specific smoothing options by default, giving you greater flexibility and control. Simply deselect any options you don't need!

Please note: The FINE option cannot be unchecked because it is required for interlocking at newly generated via locations.

This improvement was driven by your feedback—and we're thrilled to turn another user request into reality. Please let us know what you think!

---

PS Connector​

New controller-specific smoothing values
Download the newest version from Optimized Path Planning Beta folder from the RTR FileShare.

PS 0.10.0-beta

• Added robot vendor specific smoothing values to exporter.
• Add logging of diagnostics data for export and import.
• Additional warnings for stationary tools, large joint limits. etc.
• Bug fixes in interlocks, target locations, smoothing conversion.

---

Resolver Update​

In this latest release, we have added a feature that empowers you with data to make better decisions. Resolver now generates several solutions with less number of interlocks and corresponding cycle times to let you pick the one that best fits your project needs.

Today's update:

• Interlock Reduction

---

Interlock Reduction​

New post-processing step to reduce interlock zones!
We're excited to introduce automatic interlock post-processing in Resolver. Once you accept the results and stop a run (not current results), the Engine will intelligently consolidate interlock zones—without altering robot motion paths.

The output will include all possible interlock reduction options, along with a cycle_times.yaml file (see image below) detailing estimated cycle times for each result. You can then select which results file to import back to your simulation.

As always, we value your feedback—let us know how this feature works for you!

---

Resolver Update​

We continue making great progress on delivering the capabilities you have asked for. In this latest release, we drastically improved the handling of complex kinematics for robots, guns and rails. We are happy to announce we can now fully support X-type guns with kinematic loops as well as covering many previously unsupported scenarios.

Today's update:

• PS Connector 0.9.0-beta released
• Short Survey
• User Documentation

Target Order Optimization​

Find the optimal sequence in minutes
If your application has the flexibility to allow process targets to be visited in any order, you can enable "Optimize Target Order" which will generate paths to visit all targets in the shortest cycle time. If you keep this option disabled, the paths will be generated to visit the targets in the specified order, top to bottom. Not sure if it will save time? Try it out and let us know the results!

---

Download Intermediate Results​

How is the run going so far? Now you can find out!
Our engineering team has been hard at work for the past months to enable you to download intermediate results during a run without stopping it.
After you have started a run, you will now be able to "Get Current Results" that can be imported back into your simulation software. If you want to end the run and get the latest results, select "Accept Results & Stop" from the drop down menu.

---

Custom Linear Rail Positions​

Adding flexibility to give you more control
For each robot on an external RTU or linear rail, you can now specify positions to be used by Resolver to find optimal motion paths and interlocks. You can also add a stroke buffer for the minimum and maximum values. Please note that if a robot has a location or configuration at a specific target, the external axis value will be used as one of the options and displayed in "Assigned Values".

Smoothing Table in Exporter​

More knobs to turn!
In this release you will notice a smoothing table in the exporter that informs the Engine of the allowed smoothing radius values. The Engine will fine-tune smoothing at each generated via with the best choice from this table. On import, the generated values will still be converted to your robot controller's smoothing values or you can select auto-tuning just like you already do. These values were always present in the query and, as requested, they are now user-configurable.
