Selecting and designing an industrial robot mounting stand means more than putting the robot at the right height. The stand must transfer operating and stopping loads to the floor, keep the process within its required accuracy, and leave workable cable and maintenance routes. This guide is for purchasing and production engineering teams specifying a fixed, floor-mounted pedestal for a Thai factory. It covers design inputs, comparable quotations, factory acceptance testing (FAT), and site acceptance testing (SAT). A moving seventh-axis track or mobile cart is outside this scope.
A platform alone is not a design specification
A fixed pedestal sits between the robot and the floor. It commonly consists of a robot interface plate, columns and stiffeners, a bottom baseplate, and floor anchors. Leveling provisions, cable passages, and service access may also be needed. The visible purpose is to align the robot with the workpiece and fixture. Its less visible purpose is to carry acceleration and emergency-stop reactions through a continuous load path.
The robot’s rated payload describes the permitted load at its wrist; it does not establish the design load for the stand or anchors. A model-specific installation manual provides robot mass, mounting dimensions, fasteners, reaction forces and moments, and installation requirements. Yaskawa Motoman explains that the published reactions and moments should be applied at the robot mounting interface when evaluating a supporting structure. Stand height does not change those published interface values, although the structure and floor must still be evaluated for the resulting actions. Yaskawa Motoman technical Q&A.
ABB’s manuals likewise specify mounting holes, hardware, tightening conditions, and foundation requirements for individual models. A bolt size or torque from one model cannot be copied to another. Put the exact robot model and manual revision on the stand drawing. This makes later robot changes traceable. ABB IRB 1010 product manual.
Separate a fixed stand from a seventh axis at the start
A fixed stand has no travel during normal production. Its main specification concerns the robot interface, stiffness, loads, floor anchorage, cables, and service access. A seventh-axis unit needs rail and drive selection, support along its travel, cable management, travel-end measures, and a separate safety analysis. State “fixed floor-mounted stand, with no travel mechanism” on the first page of the RFQ. If the robot must move between stations, use our seventh-axis selection guide to define that different scope.
The end effector is another separate purchase, but it directly affects the load cases. Tool and workpiece mass, centre of gravity, inertia, and cycle details should be available before requesting a firm stand quotation. Our robot gripper selection guide can help establish the tool assumptions for the RFQ.
Put the stand’s design inputs on one sheet
Sharing a common design-input sheet makes supplier quotations comparable. Mark each field as confirmed, assumed, or open. Give each open item an owner and a decision date instead of letting suppliers silently fill in missing conditions.
| Input | Information from the buyer | Check in the quote |
|---|---|---|
| Robot | Make, model, mounting orientation, manual revision | Does the interface match the maker’s requirements? |
| Tool and part | Mass, centre of gravity, inertia, heaviest gripped condition | Are these included in load cases? |
| Motion | Workspace, critical poses, cycle, stopping conditions | Are normal and stopping cases distinguished? |
| Layout | Reference height, reach, fixtures, adjacent equipment | Are clashes and service space checked? |
| Floor | Drawings, material and thickness, existing anchors, embedded services | Are anchor assumptions defensible? |
| Environment | Washdown, dust, heat, corrosion, adjacent vibration | Are finish and maintenance appropriate? |
| Quality | Process position tolerance and repeatability target | Are stand and complete-cell criteria separated? |
| Safety | Guards, doors, stopping, access, removal routes | Is the cell risk assessment included? |
If the robot model is not yet fixed, obtain the interface and reaction data for each candidate and ask suppliers to show which candidates their proposal supports. A common stand may still need an adapter plate, a different cable opening, extra weight, or a revised stiffness assessment. Do not assume that a larger future robot is acceptable merely because its mounting holes fit.
How to read model-specific reaction data
Manuals may separate horizontal and vertical forces, moments about several axes, normal operation, and emergency stopping. Names, signs, and coordinate systems differ by maker and model. Attach the original table and coordinate drawing to the calculation request; do not copy numbers without context. Trace actions from the robot interface through columns, welds, the lower plate, the anchor group, and the floor. Increasing stand height can alter the overturning action that must be checked at floor level under the same horizontal force. It does not mean multiplying the manufacturer’s reaction at the robot interface by an arbitrary “height factor.” Yaskawa Motoman technical Q&A.
Ask the robot maker and structural designer which load cases and fatigue and allowable-stress criteria apply. Avoid a universal factor taken from a generic website. In its published Q&A, Yaskawa says customers need not add a factor to its published reaction values, while they remain responsible for their own structure stress and fatigue criteria. That statement is not a universal rule for every brand and application.
Do not set stand height from reach alone
Height may be needed to reach a fixture or conveyor, clear an obstruction, or improve access. A taller, narrower stand will generally make deflection and vibration harder to control. Compare several heights against robot poses, neighbouring machines, maintenance postures, cable bending, and replacement routes. Show anchor spacing and tool access on the layout, not just the top plate footprint.
ABB identifies incorrect installation, inadequate pedestal stiffness, resonance with nearby equipment, and incorrect payload or tool data among possible causes of robot vibration for a particular model. Another ABB manual states model-specific recommendations for foundation resonance. The practical lesson is that thicker plate alone may not solve a cell-level vibration problem. Define how visible vibration, process-point movement, and operation of adjacent machines will be observed and recorded. Do not copy a frequency or plate thickness from one model into a general standard. ABB CRB 1100 manual; ABB IRB 1200 manual.
Robot repeatability and complete-cell accuracy are different
A robot catalogue value is obtained under defined test conditions. It does not by itself guarantee process accuracy after stand deflection, floor vibration, fixture movement, and tool setup are considered. ISO 9283 covers industrial robot performance criteria and related test methods. If a criterion is invoked in a contract, identify the performance measure and its test conditions. ISO 9283:1998.
Specify the measurement point, workpiece holding condition, instrument, warm-up and adjacent-machine conditions, acceptance limit, and retest rule. Set the actual limit from the process requirement and measurement capability. FAT can check the fabricated stand; SAT must check the installed cell. This distinction helps identify the source of an out-of-tolerance result.
Treat baseplate, anchors, and floor as one load path
“Four anchors included” is not enough to show that the installation works. Ask for anchor type and layout, edge distance, embedment, floor material and condition, reinforcement or embedded services, installation method, and inspection record. A new foundation and an existing factory slab offer different levels of information and responsibility. If floor data are incomplete, price the stand separately from site investigation, strengthening, and anchor installation.
Baseplate flexibility matters. Hilti’s technical handbook distinguishes assumptions for a rigid plate from situations where plate deformation changes the action on anchors. Before simply choosing a larger anchor, have the designer examine plate thickness, stiffeners, welds, and the load path. The calculation method and applicable local rules must be selected for the actual floor and project. Hilti steel-to-concrete handbook.
Follow the robot model’s instructions for interface flatness and surface preparation. For example, the ABB IRB 1010 manual specifies a clean, unpainted mounting surface and particular fastening details for that model. It does not establish a universal rule for all robots. Use the adopted model’s latest manual and approved drawing as the installation authority. ABB IRB 1010 manual.
Survey an existing factory floor before installation
In a Thai operating plant, check whether the slab shown on drawings matches the site. Mark the proposed stand position and record joints, pits, embedded services, adjacent equipment, forklift routes, and maintenance access on one site plan. The building owner and structural engineer should then confirm slab construction, anchoring feasibility, and strengthening needs. If scanning or coring is needed, allow for production and restoration work.
Existing anchors cannot be reused solely because their locations fit. Their material, specification, installation record, and condition must be traceable. If a drawing says “reuse proposed,” state the acceptance criteria and fallback design. Even if floor construction is excluded from the stand supplier’s contract, define the handover and responsibility boundary.
Draw cable, hose, and maintenance space before fabrication
Leaving cable routing until after robot installation can put connectors against a column, cables in the arm’s sweep, or replacement access behind a fixed panel. Give suppliers the power, control, communication, and air connections; connector exit directions; allowable bends; fixing points; and pull-out path for replacement. A later support bracket or opening is a controlled design change because it affects the stand.
Some robot models permit internal routing for certain cables; others do not. Yaskawa Motoman describes a fieldbus route through the base of specified models and directs users to each model’s instruction manual. Do not infer compatibility from another model. For external runs, check rubbing, tension, and clashes across the full motion envelope. Yaskawa Motoman cable-routing guide.
Size service openings around the actual tasks: checking base fasteners, changing cables, grounding, and cleaning. Field-cut openings may change stiffness, coating, and cable protection, so they need engineering approval and a drawing revision.
Assess safety at robot-cell level
Raising a robot changes its reachable space, relationship to guarding, potential reach over equipment, and service posture. Structural adequacy of the stand is only one part of cell safety. ISO 10218-2:2025 covers safety requirements for industrial robot applications and cells. The integrator should assess the real layout, motion, and maintenance tasks, then define safeguards and validation. ISO 10218-2:2025.
Before fixing stand height, show guards, gates, emergency stops, access, lifting routes, and maintenance tasks on the cell plan. No single stopping or safety distance quoted in an article can replace the assessment of the actual robot, speed, protective devices, and applicable requirements. For a Thai project, name the governing local rules, company requirements, insurance requirements if relevant, and approval owner in the contract.
Make the scope behind each price visible
Send the same inputs to every bidder and compare the following lines. This reveals whether a price difference comes from structure, floor work, inspection, drawings, or warranty scope.
| Line item | Ask the supplier to state | Risk if omitted |
|---|---|---|
| Structure | Materials, plate thickness, stiffeners, welds, finish | Strength and maintainability cannot be compared |
| Design basis | Robot model, load cases, analysis scope | Future changes cannot be checked |
| Interface | Holes, pins, datum, fasteners, torque conditions | Robot may not fit on site |
| Floor fixing | Anchors, floor survey, strengthening, installation | Unplanned site costs |
| Cables | Openings, supports, protection, reserve space | Rubbing or difficult service |
| Inspection | Dimensions, welds, coating, installation, motion | Acceptance becomes disputed |
| Documents | Drawings, calculations, material and work records | Modifications are hard to trace |
| Programme | FAT, shipping, installation, SAT, training | Start-up schedule is incomplete |
Request explicit exclusions and a change approval process. When a supplier offers a performance guarantee, distinguish the robot’s catalogue performance, stand dimensions or stiffness, and the complete cell’s process result. A lump-sum “stand package” can conceal major differences.
RFQ wording you can adapt
“Supply a fixed, floor-mounted industrial robot stand without a travel mechanism. Design its interface, load cases, and fixing to the specified robot model and current installation manual. Demonstrate the load path from robot interface to existing floor and list unverified floor assumptions. Distinguish normal and relevant stopping conditions. Check cables, maintenance access, and guard interference. Submit approval drawings, inspection plan, FAT and SAT criteria, and a change log.” Add the actual model, process, quality target, and responsibility matrix.
If calculations are requested, ask for input data, load cases, coordinate system, materials, evaluation of welds, bolts, anchors, and floor, conclusions, and exclusions. Keep calculation and fabrication drawing revisions aligned. Circulate clarifications to all bidders under the same conditions.
Read the design drawing in a useful order
First overlay the robot reference frame and process datums on the cell layout. A stand may have the right outside dimensions yet point the robot origin the wrong way, put cable exits against a wall, or block the approach to a fixture. Review poses before and after gripping, waiting, maintenance, and controlled recovery after a stop, including the tool and workpiece. The relevant drawing is the actual cell layout, not an isolated robot reach diagram.
Next compare robot mounting holes, locating pins, datum surfaces, and base outline at the top with anchor locations at the bottom. Can a tool reach each top bolt? Can the installer reach each anchor? Can welds be inspected? For any cable opening, check space for both mating the connector and replacing the cable later. “A cable fits through” is weaker than “a cable can be replaced without cutting the structure.”
Finally, link each critical feature to a design basis and inspection criterion. If interface flatness matters, state the tolerance, measurement area, point in production, and whether acceptance occurs before or after coating. For a weld inspection, identify the weld and pass criterion. Model, process, and applicable rules set actual values; generic figures from an article do not. Record approval, conditional approval, or resubmission, with an owner for every open item and a clear condition for starting fabrication.
Prevent common rework through better inputs
One frequent case is selecting the robot before the tool and heaviest workpiece are known. A gripper change can shift mass, centre of gravity, and inertia, requiring renewed motion and stand-load checks. Another is describing floor work as “by site” without naming the owner of floor investigation and anchor design. A finished stand then cannot be installed on schedule. A third is excluding cables from the stand quote while expecting a protected cable route to appear automatically. Missing openings and supports lead to field modifications.
A fourth case is measuring static dimensions at FAT but only deciding motion, vibration, and process-accuracy acceptance after installation. Without agreed points and conditions, buyer and supplier results cannot be compared. A fifth is separate drawing control by fabricator, anchor installer, and robot integrator, leaving teams with different revisions of stand height or hole positions. Keep one approved revision and notify all affected parties when it changes. These problems can often be prevented by clear inputs and responsibility before any specialised calculation starts.
Hold a short pre-order review
Purchasing, production engineering, maintenance, safety, stand supplier, robot integrator, and floor contractor should review the same input sheet and responsibility matrix. Five questions are enough: Are robot, tool, and process conditions fixed? Who closes the missing floor data? Where are the design, fabrication, installation, and commissioning boundaries? Who measures each FAT and SAT item? What must be resolved before fabrication starts? The value lies in recording decisions in contract documents, not in a long meeting.
For an unresolved item, record a provisional basis, decision deadline, fallback, and price or schedule effect. If slab thickness is unknown, hold final anchor design until survey and approval. If robot selection is open, commission candidate feasibility first and machine model-specific holes after selection. This separates work that can proceed from decisions that must remain conditional.
Define FAT and SAT before placing the order
FAT should cover items that can be checked before shipping; SAT should cover those that require installation in the Thai factory. Do not mix acceptance of the fabricated stand with acceptance of the complete production cell. Agree on method, instrument, pass limit, record format, and corrective action for every criterion before award.
| Stage | Main checks | Evidence |
|---|---|---|
| Design approval | Interface, loads, height, floor fixing, cables, access | Drawings, calculations, open-items list |
| FAT | Key dimensions, mounting face, welds, coating, parts | Measurements, inspection reports, photos |
| Installation | Floor condition, anchor work, level, tightening, grounding | Installation and material records |
| SAT | Clashes, cables, motion, stops, process accuracy | Run log, risk assessment, acceptance record |
Even when the robot is absent at FAT, hole positions, datums, cable openings, and supplied fasteners and pins can be checked. At SAT, check the full motion envelope, normal cycle and controlled recovery, vibration with nearby machinery running, and process measurements. Follow the integrator’s safety plan for stop and safety-function tests; do not improvise tests at production speed.
Include early-life inspection and handover. Set any recheck interval for fasteners and anchors from the maker’s and installer’s instructions and actual use. Give maintenance teams the as-built drawings, parts list, installation and inspection records, service method, and conditions that trigger re-evaluation after a robot change.
Reassess changes after commissioning
A heavier gripper, new workpiece, faster cycle, larger motion envelope, or new vibrating machine changes the original design inputs. Record old and new tool, workpiece, and motion conditions, affected drawings, need for recalculation, measurement and safety review, and approvers. A replacement robot with a similar payload is not automatically interchangeable: compare its bolt pattern, base shape, reactions, cable exits, and service clearance.
For planned relocation, record lifting points, separable parts, components to replace, and criteria for reusing anchor holes. The new floor may differ from the old one, and the previous SAT cannot simply be carried forward. Keep approved and as-built drawings together for production engineering and maintenance.
Assign ownership of records and updates
Long-term operation needs more than a final drawing; it needs the conditions under which that drawing was approved. Link the robot model and installation manual, tool and workpiece basis, floor survey, structural calculation, fabrication drawing, installation record, and FAT/SAT results to one equipment identifier. Choose one controlled repository and record the revision, approval date, approver, and applicable robot and cell for each document. Separate contract files, engineering drawings, and handwritten site notes without a controlled master make later modifications unreliable.
If anchor positions, cable openings, or stiffeners change on site, update the as-built drawing after SAT. Decide whether the change affects performance or safety and complete any required remeasurement before closing it. Photographs alone are not a substitute for a revised drawing. Store final measured values alongside acceptance limits so future inspectors know what to compare.
Frequently asked questions
How should an industrial robot stand’s height be chosen?
Compare workpiece and fixture reach, equipment clearance, maintenance posture, floor anchorage, cable paths, and stiffness at several heights. Validate the selected layout against the robot maker’s installation conditions and the cell risk assessment.
Is there a standard anchor size or number?
There is no single value for every robot and floor. Load cases, baseplate behaviour, slab condition, anchor product, and installation method determine the design. Ask the bidder to state assumptions and price investigation or fallback work separately.
Can payload rating alone determine the stand?
No. Obtain the tool and workpiece centre of gravity and inertia, motion conditions, robot mass, model-specific reactions and moments, and stopping cases as well as rated payload.
What does a robot stand cost?
Size and mass alone do not establish price. Compare equal scopes for structure, finish, floor work, cable handling, inspection, transport, installation, and design responsibility. Mark exclusions before floor survey.
Can FAT complete acceptance?
FAT can verify fabricated dimensions and finish. Actual floor fixing, cabling, robot operation, interference, and process accuracy require site checks. Separate FAT and SAT pass criteria at order stage.
Conclusion
Start with the selected robot’s installation data, then add tool and process conditions and verify the load path from mounting plate to floor. Put height, stiffness, anchors, cabling, service access, and cell safety into one design-input set. Compare quotations on equal responsibility and acceptance scopes. Define FAT fabrication checks and SAT site-performance checks before ordering.
