Motionwell Automation works in Singapore as a machine builder and industrial automation systems integrator, and the second half of that description is the part buyers ask about. The delivered work behind it is specific: two ABB IRB 6700-200/2.60 six-axis arms at 200 kg payload and 2.6 m reach on a battery module dismantling line, a four-axis column palletizer placing cartons to plus or minus 1 mm at 6 to 10 cartons per minute, a 100 mm low-profile robot seventh axis holding plus or minus 0.5 mm repeat positioning, a precision filling and sealing machine dosing through three Nordson diaphragm valves in parallel on a stainless steel frame designed for an ISO Class 7 or Class 8 room. Each of those is a system rather than a purchase, and the company has delivered more than 150 special purpose machines since 2014 under ISO 9001:2015 and bizSAFE Level 3.
The short answer. A system integrator is the company that takes responsibility for a working production system rather than for any one component inside it. It buys robots, controllers, cameras and drives from the firms that make them, designs and builds everything between them, writes the control logic that makes them behave as one machine, proves the result on your parts, and hands over the drawings, schematics, program documentation and training that let your own team run it. The definition is a responsibility rather than a product list: whatever falls between two suppliers on your project is the integrator’s, by default.
This page is about the role itself. What the word covers, what an integrator hands over at the end, where it stops and an OEM, a distributor or a consultancy begins, which disciplines sit inside one, and who owns which number once a contract is signed. How to evaluate and shortlist one is a separate job, worked through in our guide to choosing a system integrator in Singapore. If you already have a part, a rate and a site constraint, skip both and talk to an engineer.
What Is a System Integrator, and What Exactly Is the System?
The useful part of the term is the noun, not the verb. A system is a set of parts that only has value in combination, and the combination is what has no natural supplier. Every component in an automated cell arrives with a datasheet that is true in isolation. A robot repeats to a stated tolerance. A camera resolves a stated number of pixels. A drive holds a stated position. None of those documents says anything about what happens when a person opens a door mid-cycle, when the conveyor upstream stops for four seconds, or when the part arrives rotated 15 degrees from where the gripper expects it.
That gap is the integrator’s subject. The role exists because production equipment is assembled from levels, and the levels have different owners.
| Level | What sits at this level | Who normally supplies it | What has no owner until someone integrates |
|---|---|---|---|
| Component | Motors, grippers, cameras, sensors, valves, PLCs | Component makers: ABB, Schunk, Keyence, Cognex, SICK, Festo, SMC, ifm | Whether the stated performance survives contact with your part |
| Subsystem | Robot plus controller, vision system, conveyor section, safety relay group | The vendor or its distributor | How the subsystem behaves when its neighbour faults or stops |
| Machine or cell | A station that performs a process on your product | Machine builder or integrator | Cycle time on your parts, tooling, part presentation, recovery behaviour |
| Line | Several machines with buffers, transfers and handshakes between them | Integrator, or several arguing | Which controller declares part ready, cell ready, buffer full, fault |
| Plant interface | Data out of the machine into your systems | Shared between the integrator and your IT | Recipe management, SPC logging, and the protocol the data arrives on |
Read down that table and the definition falls out. A system integrator is whoever owns the right-hand column. On a project where nobody does, the column does not disappear; it turns up during commissioning as a dispute about whose equipment is at fault, on your floor rather than on anyone’s factory floor.
The word carries a second, older meaning in enterprise IT, where a system integrator connects software systems. Industrial usage borrowed the term and kept the logic, which is why the phrase is ambiguous in search results and why an enquiry sometimes arrives asking whether we do network integration. In manufacturing, the object being integrated is physical: parts, motion, forces, tolerances and the control system that coordinates them.
What Does a System Integrator Actually Hand Over?
This is the most concrete answer to what the role is, because a role is defined by what it is contractually obliged to produce. The list below is what leaves our building at the end of a project, grouped by what each item is for.
| Group | Deliverable | What it is for |
|---|---|---|
| Physical | The machine or cell, assembled and tested at our Woodlands Link facility before it ships | The thing you bought, in a state where a factory acceptance test can be run against it |
| Physical | End-of-arm tooling, fixtures, nests, feeders and part presentation designed for your part | The pieces that exist only for your product and cannot be ordered from anyone |
| Physical | Guarding, interlocked access doors, light curtains, scanners and the safety-rated stop circuit | The access strategy the risk assessment concluded with |
| Engineering | Mechanical drawings and electrical schematics | Making a change in year four without redrawing the machine |
| Engineering | PLC program documentation, I/O list, variable list, program flow description and alarm code table | Letting your maintenance team diagnose a stop without calling the builder |
| Engineering | A complete software backup with version-controlled source and drive parameter files | Recovering the machine after a failed controller rather than rebuilding it |
| Evidence | Factory acceptance test against agreed cycle time, accuracy and repeatability, witnessed by you | Proving the numbers while the machine is still on our floor and still ours to fix |
| Evidence | Site acceptance test with real production material | Proving the same numbers with your material, your operators and your utilities |
| Evidence | Risk assessment, safety circuit validation, LVD and CE testing, and MOM lifting certification where the cell includes lifting equipment | The safety file the machine has to stand on |
| Evidence | IQ and OQ protocols prepared, PQ supported with your quality team, in regulated production | The qualification trail a regulated line is audited against |
| People | Operator manuals, maintenance schedules, spare parts lists and hands-on operator training | Whether the machine is still running the way it was handed over, twelve months later |
Two rows on that list are worth separating from the rest, because they are the ones a purchase order tends to leave implicit. The tooling and part presentation row is engineering that exists nowhere else in the world; nobody stocks a nest for your part, and the design of feeders, trays and escapements is usually where a cell’s real risk sits rather than in the arm. And the software backup row is the difference between owning a machine and renting access to it. Ask for a program archive with a named owner at quotation stage rather than at handover.
What to test each of those deliverables against, and which of them a weak supplier will quietly omit, is the evaluation question rather than the definition question, and it is covered point by point in the integrator selection framework.
Where Does the Integrator End and an OEM, Distributor or Consultancy Begin?
The boundaries are commercial rather than technical. Each of the roles below is a legitimate business, and each one is the wrong answer to some projects.
| The supplier | What it sells | What it will own on your project | What it cannot be asked to own |
|---|---|---|---|
| Component OEM or robot vendor | An arm, a controller, a camera, a drive, with a datasheet and a warranty | The component’s rated performance and its own firmware | The gripper, the fixture, the guarding, or the cycle time on your part |
| Equipment distributor | A catalogue machine at a published price, with spares under an order code | Delivery, installation and spares for that model | Redrawing the machine around your container, tolerance or line layout |
| Engineering consultancy | A specification, a layout, a tender package | The requirement document, independent of whoever builds against it | The mechanism, the acceptance evidence, or the number the machine has to hold |
| System integrator and machine builder | A working system built against your part, your rate and your site | Interfaces, tooling, control logic, the acceptance evidence and the documentation pack | Certifying its own machine as a notified body, or manufacturing the components it buys |
| Facility or main contractor | Building services, utilities, civil work | Power, air, drainage and floor to the agreed points | Anything about how the machine performs once connected |
The row that causes trouble on real projects is the second one. A distributor’s packaged cell and an integrator’s custom cell can look similar in a proposal, and they are not comparable objects: one is configured, the other is drawn. If a proven standard machine covers your part at your rate, the distributor route is faster and cheaper, and the shortlist version of that comparison is on our page about what kind of automation company you actually need.
The consultancy row deserves the opposite defence. If you have four suppliers to compare and no document all four can quote against, the missing item is a requirement rather than a vendor, and writing an automation URS turns four differently shaped proposals into one comparable table.
Why Do Two Companies Called System Integrators Do Different Work?
Because the label covers two businesses that overlap only in the middle. One assembles bought equipment into a working line: robots, conveyors, controls and vision, all purchased, arranged and programmed. The other also designs equipment nobody sells, because the sequence the process needs does not exist in any catalogue. Both are integrators. Only the second can be asked to draw a mechanism.
That distinction changes what a buyer is allowed to ask for. If your part needs a fixture that holds it in one orientation to a tolerance no standard nest achieves, the assemble-only integrator has to change your specification to fit the available equipment, while a machine builder treats it as an engineering task inside scope. Motionwell sits on the second side of that line and is explicit about it on the capabilities index: we design and build production equipment to order, and we are not a distributor reselling someone else’s machines or a consultancy that stops at a drawing.
The supply position is a second axis, and it is separate from the first. Some integrators build on one robot platform and know it deeply; others carry several and select per application. Ours is multi-brand: we buy and integrate ABB industrial and SCARA robots, JAKA collaborative arms with seven units purchased to date, Yamaha SCARA for lighter handling, and Inovance, HitBot and Lanxin platforms where the application suits them, with robot programming and end-of-arm tooling work running across FANUC, ABB, KUKA, Yaskawa, Yamaha and JAKA. Grippers come from Schunk and DH Robotics, vacuum components from SMC and Festo, sensing from SICK and ifm, and vision from Keyence and Cognex. On mobile robots we have been the authorised SIASUN AGV distributor for Southeast Asia since 2017 and integrate Youibot and MiR platforms where a fixed route is the wrong answer. We also have integration experience on customer-supplied Universal Robots arms across three projects, which is a different thing from stocking them.
A third shape exists and is worth naming so it is not mistaken for a contradiction: a company can hold a distributorship for one product line while building machines around everything else. The test that separates the shapes is not the brand list. It is what happens when the catalogue does not contain the answer.
The consequence for brand selection is smaller than the brochures suggest. Payload, reach, speed, precision, safety mode and cost usually leave two or three platforms standing, after which the platform your maintenance team already stocks spares for and has been trained on tends to win on cost of ownership. The engineering detail behind that selection sits on our robot integration services page.
What Disciplines Sit Inside a System Integrator?
An integrator is an unusual kind of engineering company because it has to be several at once. A cell that fails at commissioning rarely fails in one discipline; it fails at a seam between two of them.
| Discipline | What it produces | Platforms and tools in our work |
|---|---|---|
| Mechanical design | Machine frames, jigs, fixtures, gauges, pallets, vacuum and pneumatic tooling, robotic end effectors | SolidWorks 3D design, FEA on critical structures, tolerance analysis on precision assemblies |
| Electrical design | Schematics, panel layout, cable routing, safety circuit design and panel commissioning | Control panel design and build, LVD and CE testing |
| Controls and software | Machine sequence code, HMI screens, motion control, recipe management, SPC data logging | Siemens, Allen-Bradley, Omron, Mitsubishi, Beckhoff and Inovance platforms, with OPC-UA, EtherNet/IP and PROFINET networking |
| Machine vision | Camera and lens selection, lighting design, algorithm integration, calibration against real samples | Keyence and Cognex; dome lighting on the SCARA sensor panel line |
| Fabrication | Precision components made to our own drawings rather than sourced to a description | CNC machining, sheet metal fabrication, precision grinding and surface treatment in our Woodlands Link manufacturing units |
| Project management | Milestone gates, change control, factory and site acceptance protocols | Design Center for engineering, Assembly and Integration Center for build and factory acceptance |
Two things follow from that table. First, an integrator that designs its own fixtures can revise a bracket it drew itself within a day, even when the part is cut by a subcontractor, because the drawing and the decision stay in one office, which matters during the weeks when a fixture is being adjusted against real parts. Our engineering, build and test sit across five units at 20 Woodlands Link, and what happens in each is set out on the about page.
Second, the disciplines are not equally forgiving. Mechanical and electrical work follows engineering rules and behaves predictably. Vision depends on optics, surface finish, ambient light and algorithm tuning, which is why a station that passes in a lit workshop can start rejecting good parts three weeks into production, and why cameras get specified against your actual samples rather than from a catalogue. How that specification is done is on the machine vision inspection page.
Who Owns the Cycle Time, the Safety File and the Handshakes?
Naming the owner of each item is the practical form of the definition, and the table below is the version we work to. The point of writing it down before a contract is that every unowned row surfaces later at a worse moment.
| Item | Who owns it | How it is evidenced |
|---|---|---|
| Product geometry and its revision freeze | You | Drawings and samples issued before detail engineering begins |
| The rate the machine is bought to hold | You, stated; us, proven | Agreed at concept, tested at factory acceptance on your parts |
| Part presentation into the station | The integrator | Feeder, tray or nest proven against the full tolerance range, not the nominal part |
| Cycle time on your actual parts | The integrator | Timed with vision acquisition, settling, gripper actuation and PLC handshake counted in |
| Risk assessment under ISO 12100 | Integrator-led, decided jointly | A documented assessment that drives the design rather than following it |
| Performance level of each safety function | The integrator | Rated and validated under ISO 13849-1; both delivered robot cells described on our robot page landed on Performance Level d |
| Guard and scanner positions | The integrator | Calculated under ISO 13855 from approach speed and the stopping performance measured on the built cell |
| Line handshakes: part ready, cell ready, buffer full, fault, reject asserted | Agreed in writing between both sides | Signal ownership settled before either side is built |
| Conformity of the finished machine | You place it in service; we supply the technical file | We are not a notified body and do not issue CE certificates |
Three standards decide most of the safety column and they divide the work cleanly. ISO 10218-1 covers the robot as a product and is the arm manufacturer’s document; ISO 10218-2 covers the robot system and its integration, which is the machine builder’s share. Each individual safety function is then rated for performance level under ISO 13849-1. One edition fact belongs in any specification written this year: ISO 10218-1:2025 was published in February 2025 as the third edition and the first substantive revision since 2011, and it references the 2023 edition of ISO 13849-1, so a design still documented against the 2015 edition will need its performance level calculations restated when the machine is reassessed.
The boundary that catches people is not new equipment but modified equipment. The European Commission states that the Machinery Directive applies to products placed on the market for the first time and also when existing machinery is modified to such an extent that it becomes de facto new machinery. Adding a robot to a machine signed off years ago can cross that line and put whoever did it in the position of placing new machinery on the market. Where the line falls is a judgement made per project, and it has to be settled before scope is fixed rather than after. The Directive applies to the EU market until 19 January 2027, after which Regulation (EU) 2023/1230 applies with no transitional period.
Singapore adds its own layer. CE marking is not required here, but the Workplace Safety and Health Act requires dangerous parts of machinery to be securely fenced and places duties on the occupier and on anyone supplying machinery for use at work, and many multinationals operating locally specify CE conformity as an internal standard regardless. The workflow that produces the file is on our machine safety and CE marking page.
What Is a System Integrator Not?
Worth being direct about the limits of the role, because a definition that only expands is not a definition.
An integrator is not a component manufacturer. We do not make robot arms, controllers, cameras or drives; we buy them, and the brand of the arm is usually the least interesting decision in a project. It is not a notified body either: we build to a specification, produce the technical file and support your conformity work, but the certificate is not ours to issue. It is not a contract manufacturer, so we hand over a machine rather than run your production on ours. And it is not a software vendor: the control and recipe software ships with the cell rather than as a licence, and we are not a vision algorithm house, so we specify the camera, the lens and the light and prove the result on your samples.
There is also work an integrator should decline outright. We do not build production welding cells. And where a distributor’s packaged cell or a proven standard machine covers your process better and cheaper than anything we would draw, that is what we will say during concept review rather than quote around it. This is the one concession on this page and it is a real one: a custom build is the right answer when the sequence exists in your process sheet and in nobody’s catalogue, and the wrong one when it does not.
The role also stops at your boundary. An integrator does not own your product design, your process recipe, your site utilities, your production schedule or your operators. Where those inputs are late or unstable, no amount of engineering on the other side compensates, and the largest schedule risk in a custom build is late finalisation of the product design rather than anything happening in the workshop. The commercial sequence that manages exactly this, gate by gate, is on our page about how an automation project runs.
Conclusion
A system integrator is defined by the column nobody else fills: the interfaces between bought components, the tooling that exists only for your part, the control logic that makes several suppliers’ equipment behave as one machine, and the evidence that the result holds on your parts rather than on a datasheet. Everything else in the definition follows from that. The deliverables list exists because the responsibility has to be provable at handover. The boundaries with OEMs, distributors and consultancies exist because those firms sell objects, while an integrator sells a working combination and the accountability for it.
If you are deciding whether the role is what your project needs, the next question is a scoping one rather than a definitional one, and the answer usually arrives faster than a brochure round. Send the part with its real tolerance, the rate at peak, the number of format variants, and a layout of the space, and contact the Motionwell team for a straight technical answer about whether you need a custom build, a standard machine, or a feeder rather than a robot.
