How does the commissioning of a turnkey robot solution work?

Written by Unchained Robotics | Apr 23, 2026 12:15:42 PM

Commissioning for turnkey robot solutions is the structured process that transforms a robot cell into a safe, connected and production-ready system. It demonstrates that the robot, tools, peripherals, software and safety functions work together in the desired cycle time, quality and operational stability on the customer's shop floor.

For production managers, automation engineers and plant managers, commissioning is the point at which the risk of commissioning becomes visible. A good commissioning process reduces delays, shortens ramp-up and creates a stable foundation for long-term performance. If the commissioning process is weak, unresolved problems are shifted to production.

Turnkey robot solutions combine design, build, test and handover

A turnkey robot solution is a complete automation system delivered by a supplier, usually a system integrator. The supplier takes responsibility for the cell concept, mechanical design, control, safety, assembly, testing, installation, commissioning, training and handover.

This delivery model is important because commissioning is not an isolated technical step. Commissioning is the touchstone for the entire turnkey promise. The system integrator must demonstrate that the delivered robot cell meets the agreed user requirements, safety requirements and production targets in practice, not just in the design documents.

For buyers, this means that the commissioning should clearly answer 3 questions:

  1. Does the robot cell run safely?
  2. Does the robot cell achieve the required performance and quality?
  3. Can operators and maintenance teams operate the robot cell without having to rely on the integrator for every problem?

Commissioning goes through 2 acceptance stages

The commissioning of turnkey robot solutions usually goes through 2 formal test points: FAT and SAT.

Stage Location Main purpose Typical result
FAT Integrator location Verification of build quality, controls, safety logic and basic process performance prior to shipment FAT report with open points, concessions and shipping authorization
SAT Location of the customer Validation of performance with real interfaces, operators, materials and production conditions SAT or handover certificate with punch list if required

This two-stage structure reduces risk in a practical sequence. FAT eliminates avoidable design and construction issues prior to transportation. SAT confirms that the same robot cell works under real plant conditions.

A repeated lesson from real commissioning projects is simple: problems that should have been found during FAT become expensive during SAT. Fixing problems on site takes more time, involves more people and disrupts the plant schedule much faster than corrections in the factory.

Pre-commissioning defines scope, interfaces and acceptance criteria

Pre-commissioning determines whether commissioning is controlled or chaotic. In the most successful projects, the scope, interfaces and test logic are defined before the first electrical movement.

The most important results of pre-commissioning

A solid pre-commissioning package includes 7 core elements:

  1. URS and functional specification: throughput, product variants, tolerances, safety modes and quality requirements
  2. Interface definition: PLC tags, fieldbus mapping, IP planning, network rules and device handshakes
  3. Risk assessment and safety concept: standards, safety methods, safe states and required performance levels
  4. FAT and SAT test plans: pass/fail criteria, sample sizes, fault scenarios and evidence to be recorded
  5. Layout and supply plan: Footprint, cable routing, air supply, power supply and environmental conditions
  6. Spare parts and equipment strategy: critical spare parts, wear parts, calibration points and replacement logic
  7. RACI and escalation path: who decides, who approves and how are scope changes handled?

Why pre-commissioning changes the outcome

Delays in commissioning rarely start with robot programming alone. In real projects, delays often start earlier with missing signals, unclear component tolerances, undefined operator sequences, incomplete network approvals or delayed safety decisions.

For this reason, the best commissioning programs treat FAT and SAT as proof-oriented milestones. Each acceptance point should relate to a written requirement, a test step and a named owner.

FAT tests the robot cell before delivery

Factory acceptance testing proves that the robotic cell is ready to leave the integrator's factory. FAT should not be treated as a demo. FAT is a structured test event with a fixed specification.

Typical FAT scope

A robust FAT usually covers these 7 areas:

  1. Design verification: mechanical, electrical and pneumatic assemblies conform to drawings and parts lists
  2. I/O and motion checks: Inputs, outputs, homing routines, axis limits and interlocks behave correctly
  3. Safety check: Emergency stop switches, light curtains, door interlocks, safety PLC logic and safe movement functions react correctly
  4. Process verification: Representative parts, fixtures and cycle sequences meet baseline expectations
  5. Exception handling: Recovery from mishandling, missing parts, sensor errors or loss of communication works as intended
  6. Verification of data and traceability: Recipes, user roles, event logs and backup routines function correctly
  7. Documentation review: manuals, schematics, risk files and maintenance documents are complete enough for shipment

What a good FAT output looks like

A useful FAT output is not "pass" or "fail". A useful FAT output is a signed report with:

  • tested functions
  • observed results
  • remaining deviations
  • approved concessions
  • Owner of the measures
  • Deadlines before dispatch

A practical lesson from real-world FAT events is that the recovery logic deserves as much attention as the nominal cycle. A robotic cell that runs cleanly in a happy path demo can still fail in production if operators are unable to fix jams, missing parts or sensor errors in a safe and repeatable way.

Site preparation eliminates avoidable startup delays

Site preparation determines how quickly the robot cell goes from delivery to the first productive run. Good site preparation shortens the start-up curve. Poor site preparation turns installation into troubleshooting.

Checklist for site preparation

Before the robot cell arrives, you should check these 5 areas:

  1. Foundations and mounting points: Levelness, anchoring, access and vibration requirements
  2. Power, air and network: labeled connections, tested capacity and approved addresses
  3. Material flow: Staging area, forklift routes, pallets, bins and operator access areas
  4. Environmental conditions: Temperature, lighting, cleanliness and ESD controls where relevant
  5. IT and OT policies: VLANs, firewalls, user accounts, backup rules and remote support permissions

A common experience during commissioning is that system-side dependencies often hinder progress more than the robot itself. A missing network connection, a delayed firewall release or an unapproved PLC handshake can cost more time than a mechanical setting.

The installation integrates the robot cell into the system environment

Installation begins when the delivered robot cell is positioned, mounted, wired and connected to the system infrastructure. In this phase, a tested, stand-alone system becomes an integrated production system.

Main tasks during installation

Installation and integration usually include

  • Leveling and aligning the base frame
  • Alignment of fixtures and EOAT
  • Fieldbus and PLC integration
  • Checking the I/O on the system side
  • Validation of safety devices and access points
  • Creation of backups for controllers, PLCs and HMIs

Why system integration changes the system behavior

A robotic cell often behaves differently at the customer's site than it does in the integrator's workshop. Real material tolerances, floor conditions, operator access patterns, timing of upstream equipment and lighting conditions can all change system behavior.

Therefore, core tests should be repeated during on-site commissioning instead of assuming that the FAT results will be transferred to production unchanged.

SAT proves performance under real production conditions

Site Acceptance Testing validates the turnkey robot solution in the real operating environment. SAT confirms that the robotic cell works with the customer's parts, operators, line interfaces, maintenance procedures and production rules.

Typical SAT criteria

SAT typically tests 6 performance areas:

  1. Throughput and Cycle Time: Required performance is achieved with realistic line interactions.
  2. Quality metrics: First pass yield, placement accuracy, torque confirmation or other defined process goals are met
  3. Changeovers and recipes: all approved product variants run according to documented procedures
  4. Operator workflows: HMI logic, authorizations, loading, unloading and interventions work in practice
  5. Maintenance routines: interlock/tagout, learning access and preventive maintenance tasks are safe and practical
  6. Downtime recovery: Resetting emergency stop switches, clearing jams, sensor faults and short communication failures can be handled without unsafe improvisation.

What SAT should do

A solid SAT ends with:

  • a signed SAT or handover report
  • a documented list of open points
  • deadlines for minor punch list items
  • a common understanding of the start of the warranty and responsibility for support

A recurring lesson from real SAT phases is that "the robot moves" is not acceptance. Acceptance begins when the robot cell operates reliably across shifts, operators and normal production fluctuations.

Ramp-up is what turns a functioning robot cell into a stable production system.

Commissioning is not complete when the robot cell has completed its first successful cycle. Commissioning is complete when the performance of the robot cell is sufficiently predictable for production planning.

Most important ramp-up levers

Ramp-up usually improves performance through 5 levers:

  1. Path and motion optimization: blend points, zone settings, acceleration and protected distances
  2. Image processing and sensor optimization: lighting, calibration, thresholds and detection logic
  3. Improvement of fixture and EOAT: rigidity, compliance, gripping force and quick-change repeatability
  4. Buffering and line balance: conveyor timing, reduction of starvation and reduction of jamming
  5. Ease of use during recovery: Better HMI prompts, guided recovery steps and controlled manual actions

Metrics that should be visible early on

A commissioning dashboard should track:

  • OEE
  • Cycle time versus takt time
  • Yield on first pass
  • scrap rate
  • MTBF and MTTR for critical subsystems
  • Changeover time
  • Safety incidents and near misses

A practical lesson from real ramp-ups is that output instability is often due to interaction effects rather than individual failures. A robot path may be acceptable on its own, but unstable line control, inconsistent part presentation and unclear operator recovery can still reduce overall performance.

Roles and responsibilities ensure quick decisions

Commissioning goes faster when responsibilities are visible. It slows down when technical, safety and production decisions are made between different teams.

Typical distribution of roles

Role Main responsibility for commissioning
System integrator Design, build, FAT, installation, commissioning, training and follow-up of open issues
Project management at customer site Site readiness, stakeholder coordination and final acceptance decisions
Control engineer PLC, robot code, interfaces, safety logic and data acquisition
Quality management Sampling logic, quality approval and acceptance thresholds
Safety officer Compliance with regulations, plant procedures and approval of safety validation
Operation and maintenance Usability feedback, recovery validation and routine ownership
IT/OT management Network access, user control, backup policies and remote support rules

A simple RACI prevents avoidable delays. During commissioning, an unclear ownership situation leads to longer downtimes than many technical errors.

Handover transfers knowledge, backups and operational discipline

A turnkey robot solution only creates long-term value if the customer team can operate and maintain it independently.

Handover package for commissioning

A complete handover package should include the following:

  • mechanical and electrical drawings
  • Parts lists and pneumatic diagrams
  • Risk assessment and safety validation records
  • PLC, robot and HMI source files and compiled versions
  • Backup copies and recovery instructions
  • SOPs for operation, retrofitting and troubleshooting
  • Preventive maintenance schedules and calibration intervals
  • Spare parts list with stocking instructions
  • Training records and sign-off sheets for competence

Training should be role specific

Operators, technicians and engineers do not require the same level of training.

  • Operators need safe startup, stop, changeover and recovery routines
  • Maintenance teams need diagnostics, replacement logic and backup handling
  • Engineers need code structure, parameter management and controlled change procedures

A practical lesson from real-world handovers is that rushed training pushes avoidable calls into the support phase. The robot cell may be technically ready, but production still grinds to a halt if the customer team lacks confidence in the recovery process.

Common risks during commissioning can be avoided at an early stage

Most commissioning problems are predictable. The value lies in recognizing them before they cause delays on site.

6 common error patterns

  1. Vague requirements: Unclear throughput, quality or variant specifications lead to late discussions
  2. Delayed safety decisions: Belatedly added safety precautions force redesign and revalidation
  3. Weak failure testing: recovery logic fails when real failures occur
  4. Insufficient site readiness: utilities, networks and access are not ready on arrival
  5. Lack of data strategy: tags, logs and dashboards are undefined
  6. Incomplete training: Operators escalate routine issues that should be dealt with on site

In commissioning practice, the most expensive problems are often not the most technical. They are usually the problems that no one recognized early enough.

Acceptance depends on documented criteria, not assumptions

A turnkey robot solution is commissioned when it meets the documented acceptance criteria and the customer can take over controlled operation.

Typical acceptance criteria

Acceptance usually depends on the following 5 conditions:

  1. Proven throughput and cycle time for approved recipes
  2. required quality level over a defined test run
  3. validated safety functions and complete safety documentation
  4. Successful recovery after agreed error scenarios
  5. Training completed and handover documents provided

Open points do not always block acceptance, but open points must be documented, limited in scope and linked to a clear solution plan.

A best business practice is to align final payment and warranty start milestones with SAT acceptance and the agreed punch list plan. This keeps technical and contractual incentives aligned.

Aftercare protects uptime after commissioning

After commissioning, the priority shifts from executing commissioning to uptime and continuous improvement.

The 4 pillars of aftercare

  1. Warranty and support SLAs: response time, escalation path and remote access rules
  2. Preventive maintenance: calendar-based and cycle-based inspection and replacement tasks
  3. Change management: version control, backup discipline and traceable code updates
  4. Continuous improvement: structured review of recurring losses and controlled optimization updates

A robot cell that starts well but has no disciplined aftercare will lose performance over time. A robot cell with good aftercare usually performs better 3 months after the SAT than on the day of handover.

Short FAQ

FAT checks the turnkey robot solution before delivery. SAT validates the turnkey robot solution on the customer's construction site under real operating conditions.

The main parties involved in commissioning are the system integrator, the customer's project manager, control engineering, quality, safety, operations, maintenance and IT/OT.

A turnkey robot solution is fully commissioned when it has passed the SAT test based on documented criteria, training has been completed, the handover package has been delivered and the remaining open points have been formally agreed.

The best way to reduce the risk of commissioning is to define measurable requirements early, test troubleshooting thoroughly, prepare the site in detail and track commissioning performance from day one.

Bottom line

Commissioning turnkey robotic solutions is the process that transforms a designed robotic cell into a safe, stable and production-ready facility. When FAT, installation, SAT and ramp-up follow clear acceptance criteria, it results in faster commissioning, lower risk and better long-term automation performance.
