How to Choose a Robotics Integrator
Choosing a robotics integrator is one of the higher-consequence decisions a plant engineer or engineering manager makes, because the integrator you pick owns the gap between a robot that works in a simulation and a cell that runs reliably on your floor for the next decade. The purchase looks simple from the outside: pick a firm, buy the arm, install it. Most of the real risk lives somewhere else, in commissioning, in integration with your existing controls, and in who answers the phone eighteen months later when the cell throws a fault at 2 a.m. This is a framework for evaluating a robotics integrator the way a serious buyer should, built around the criteria that separate a dependable partner from a firm that disappears after sign-off.
According to the International Federation of Robotics, 542,000 industrial robots were installed worldwide in 2024, marking the second-highest year on record. The criteria below favor integrators who have done the work across platforms and across industries. That is deliberate. Each question exposes whether a firm can carry a project all the way through, and the honest answers narrow the field fast.
Start with platform certification, and know what “authorized” actually guarantees
The first filter is whether the integrator holds a real, current authorization from the robot platform you plan to run. A FANUC Authorized System Integrator has met FANUC’s technical and training requirements and works inside FANUC’s support and parts channel. That status tells you the firm’s engineers have been trained on the platform, have access to factory-level technical support, and are accountable to the manufacturer for how they deploy the equipment.
What authorization does not guarantee is execution. It confirms competence with the hardware; it says nothing about whether the firm will hit your timeline, integrate cleanly with your PLCs and safety systems, or support the cell after commissioning. Treat certification as a floor, not a finish line. A certified integrator who has run twenty cells like yours is a different proposition from one running their third. Ask how many systems a firm has deployed on your specific platform in the last two years, and ask to speak with the plant that ran the most recent one.
Weigh multi-platform capability against single-platform specialists
A single-platform integrator can be excellent inside their lane. The risk shows up at the edges of the cell, where the robot has to talk to your control system, your HMI, your data historian, and your safety architecture. Plant floors are rarely single-vendor environments. A palletizing cell might pair a FANUC arm with a Siemens PLC and an Ignition SCADA layer, and the integration seams between those systems are where projects stall.
A capable multi-platform integrator can own the whole cell rather than handing off the parts it does not cover. Patti Engineering holds CSIA certification alongside Siemens Solution Partner, Ignition Premier Integrator, and FANUC Authorized System Integrator status. The combination matters because it removes the finger-pointing that happens when the robot vendor blames the controls vendor and neither owns the fault. When one firm is accountable for the arm, the PLC, and the data layer, there is no seam to hide in.
Look for cross-industry pattern recognition
Integrators who have only ever worked in one vertical bring that vertical’s assumptions to your plant, and those assumptions do not always transfer. A partner that has deployed robotics across automotive, food and beverage, pharma, semiconductor, and aerospace has seen more failure modes and more constraints, and that breadth shows up as better instincts about what will go wrong before it does.
According to the Association for Advancing Automation, North American companies ordered 36,766 robots valued at approximately $2.25 billion in 2025, a 6.6% increase in units over 2024. Cross-industry experience also matters for regulatory and environmental fit. A wash-down food line, a cleanroom, and a high-throughput automotive weld cell each impose different demands on how a robot is specified, guarded, and maintained. With pattern recognition across those environments, a good integrator raises the right constraints early, when changes are cheap, instead of discovering them during commissioning, when they are expensive.
Pin down who owns commissioning and follow-through
This is the criterion buyers underweight and later regret. Plenty of firms can sell and design a robotic cell. Far fewer see it cleanly through commissioning, runoff, and the ramp to full production rate. Ask directly who is on site during commissioning, whether they are the same engineers who designed the cell or a separate crew, and what the firm’s definition of “done” actually is.
A serious integrator ties completion to production performance rather than to installation. The cell is finished when it holds cycle time and uptime at rate, under your operators, with your parts. Patti’s core strength is execution follow-through: the technical rigor of a large firm with the ownership mentality of a smaller one, which shows up as engineers who stay on the problem until the line runs. Ask any integrator for a specific example of a project that went sideways and how they handled it. The answer reveals more than any capability slide.
Verify references, safety, and post-install support
References are only useful when they are specific. Ask for a plant running a system comparable to yours in scale and platform, and put two questions to that plant: did the integrator hit the schedule, and were they still responsive six months after sign-off. A firm confident in its follow-through will hand over that contact without hesitation.
Safety is non-negotiable and a genuine differentiator. A competent integrator designs the safety system into the cell from the start, sizes guarding and light curtains to the actual reach and speed of the robot, and documents the risk assessment. Post-install support is the other half of the decision. Find out what support looks like after commissioning: response time, remote diagnostics, spare-parts access, and whether the firm keeps the engineers who know your cell reachable. A robot runs for a decade or more, and the integrator relationship should be built to last that long.
Honest answers to the objections you are probably weighing
“We’ll just use the OEM’s team”
The robot OEM knows the arm better than anyone, but what the OEM team typically does not own is the integration with your existing controls, your SCADA, and your safety architecture. The OEM’s priority is selling and supporting its own hardware, not orchestrating a multi-vendor cell on your floor. For a drop-in cell from a single vendor, the OEM path can work fine. For anything that touches the rest of your automation, an integrator who owns the seams is usually the safer bet.
“We already have an integrator”
That is often the right reason to keep them. The question worth asking is whether your current integrator covers the platforms and the scope this specific project needs. If the work spans robotics, controls, and industrial software, and your integrator is strong in only one of the three, a capability gap on a critical project costs more than the comfort of the existing relationship. Bring in a second opinion on the projects that fall outside their lane.
“This will be too disruptive to production”
Disruption is a planning problem, and solving it is the integrator’s job. Integrators that have done retrofits in live plants sequence the work around your schedule, stage as much as possible offline, and compress the on-floor window. Ask a prospective firm to walk you through how it would phase the installation around your production calendar. Vague answers here are a warning sign.
How Patti Engineering approaches robotics integration
Patti has integrated robotics into manufacturing plants since 1991, across automotive, food and beverage, pharma, semiconductor, and aerospace. The firm holds FANUC Authorized System Integrator status alongside CSIA, Siemens, and Ignition certifications, which means one team can own the robot, the controls, and the data layer of a cell instead of stitching vendors together. That combination maps directly to the criteria above: platform authorization, multi-platform scope, and accountability that runs through commissioning.
Frequently Asked Questions
A FANUC Authorized System Integrator has met FANUC’s technical and training standards and operates inside FANUC’s support and parts channel. In practice, the firm’s engineers are trained on the platform, can reach factory-level technical support, and are accountable to FANUC for how they deploy the equipment. The authorization is a real credential that confirms competence with the hardware. It does not, on its own, tell you whether the integrator will hit your schedule or support the cell afterward. Read it as a required floor for a FANUC project, then evaluate execution separately.
Match the integrator to the cell. A single-platform specialist can be excellent when the project is a self-contained cell on one vendor’s equipment. Most plant-floor projects are not that clean; the robot has to integrate with your PLCs, HMI, SCADA, and safety systems, often from different vendors. A multi-platform integrator certified across robotics, controls, and industrial software can own those seams rather than handing them off. That single point of accountability keeps the robot vendor and the controls vendor from blaming each other when a fault appears at the boundary between their systems.
Ask for a reference plant running a system comparable to yours in platform and scale, then keep the questions concrete. Did the integrator hit the committed schedule, or did it slip. Was the cell commissioned to full production rate, or did it stall short of it. Were they still responsive six months after sign-off when something needed attention. A confident integrator will connect you with that plant without friction. A vague, hand-picked reference that cannot speak to a project like yours is itself an answer.
Ideally the same engineers who designed the cell, or a team in close continuity with them. Commissioning is where design assumptions meet your real parts, operators, and cycle time, and a clean handoff there depends on the people who understand the intent behind the design. Ask a prospective integrator who will be on site during commissioning and runoff, and how the firm defines a finished project. The strongest answer ties completion to sustained production performance at rate, not to the day the equipment powers on.
Expect defined response times, remote diagnostics, spare-parts access, and continued reach to engineers who actually know your cell. A robot runs for a decade or more, and faults, product changes, and optimization needs will come up across that life. The integrators worth choosing treat support as part of the relationship and can tell you exactly how a support call is handled and who picks it up. Ask what support looks like a year after commissioning. The specificity of that answer tells you whether the firm intends to stay a partner or move on.
The evaluation criteria are the same, but the emphasis shifts. Collaborative robots share space with people, so the safety assessment, the risk analysis, and the speed-and-force limits carry more weight, and the integrator’s fluency in collaborative-application safety standards matters more. Throughput expectations also differ, since a cobot trades peak speed for flexibility and human proximity. If your project centers on collaborative robots, weight the integrator’s collaborative-safety experience and application judgment heavily, and ask for a reference cell that runs alongside operators rather than behind hard guarding.
Use this framework to press every candidate on certification, multi-platform scope, commissioning ownership, and post-install support. If you want a second opinion on a robotics project, start with a conversation about your specific cell and your production constraints, and judge for yourself whether the follow-through matches the credentials.
