At Automate 2025, Realtime Robotics officially launched Resolver, a cloud-native software platform designed to dramatically simplify and accelerate the design, programming, and optimization of robotic workcells. Developed in response to persistent challenges faced by manufacturers and integrators, Resolver aims to streamline robotic deployments from concept to commissioning.
The product responds directly to what Ville Lehtonen, VP of Product at Realtime Robotics, calls a “multi-layered challenge.” While optimizing cycle time remains a clear objective, Resolver also addresses deeper inefficiencies in the robotic design and validation workflow. These include path planning bottlenecks, sequencing issues, reachability validation, and the burdens of mechanical design iteration.
“Cycle time is where it hurts first,” Lehtonen explained in an interview with Rocking Robots. “But the real surprise was how much time is actually lost upstream, when mechanical engineers hand off CAD models without knowing if a robot can even reach all targets. It’s like writing code without a compiler—hugely inefficient.”
Resolver functions much like a compiler, enabling engineers to rapidly test robot placements, tool options, and sequencing scenarios in simulation environments. Initially integrated with Siemens Process Simulate, Resolver evaluates thousands of motion path combinations in the cloud, automatically defining collision-free movements and interlock signals.
In one documented case, engineering teams using Resolver achieved an 18% cycle time improvement on complex cells—performance gains that would be nearly impossible to reach manually. “Even experienced engineers eventually hit a wall,” Lehtonen noted. “We don’t brute-force our way through the problem; Resolver reallocates tasks, changes execution order, and rapidly explores alternatives no human could attempt within a deadline.”
Beyond motion planning, Resolver is increasingly used during the early design phase. Instead of waiting for simulation teams to validate reachability or compare end-of-arm tooling, engineers can now get instant feedback on whether a given configuration will meet performance targets. This allows for a more iterative and efficient proposal and prototyping process. Lehtonen likened the shift to his early experience in programming: “When you go from a compiler that takes two hours to five seconds, everything changes—even the way you think about solving problems. Resolver has a similar effect on workcell design.”
Manufacturers and integrators already using Resolver report substantial reductions in development time. Marco Bizjak of FFT, a systems integrator specializing in digital factory solutions, said, “What used to take months to accomplish can now be measured in hours. Resolver eliminates the most time-consuming aspects of industrial robotics—programming and optimization.” According to Realtime Robotics, some teams are now building and simulating multi-robot cells from scratch in under an hour—enough for proposal-level analysis and early-stage design validation.
To maximize adoption, Resolver is offered via a flexible usage model with unlimited optimization runs, particularly targeting line builders and system integrators managing large robot fleets. The company also works closely with simulation software vendors and robot OEMs to ensure compatibility across ecosystems. “We’re not trying to replace existing simulation tools,” Lehtonen said. “We just want to be the ‘resolve’ button that gives users supercomputer-level planning power from inside their familiar tools.”
Realtime Robotics plans to expand Resolver’s capabilities throughout 2025. The next development phase focuses on enhancing support for early-stage design teams, including features that assist with robot and tool selection and automatic positioning. The software will also gain functionality to support compliance with OEM programming standards and enable large-scale line balancing, especially for complex operations involving hundreds of interchangeable tasks.
Longer-term, the company sees potential for Resolver to support small and medium-sized enterprises. By providing affordable API access, Realtime envisions low-cost applications that could make sophisticated robot programming accessible even to smaller manufacturers. “There’s nothing preventing robots from being adopted more widely—except complexity,” said Lehtonen. “With Resolver, we’re working to change that.”
