How to Build a Robot RFI or RFP: Requirements Buyers Should Define Before Asking for Quotes

A robot procurement project often starts with a simple question: “Which robot should we buy?” But that question is usually the wrong starting point. Before any supplier can provide a meaningful quotation, the buyer needs to define what the robot must accomplish, what constraints the site imposes, and what commercial and support conditions matter across the project lifecycle. This article walks through the structure of a robot RFI (Request for Information) and RFP (Request for Proposal), the inputs buyers should prepare, and how to make supplier responses genuinely comparable.

Why Robot RFIs Fail When the Task Is Described Too Vaguely

A common reason a robot RFI produces unhelpful responses is that the task description is too vague. When a buyer writes “we need a robot for material handling” or “looking for a palletizing robot for our factory,” every supplier will respond with a different interpretation—and every quotation will be based on different assumptions about payload, cycle time, layout, interfaces, and support scope.

The result is a pile of proposals that cannot be compared side by side. One supplier quotes a robot with a 10 kg payload; another assumes 30 kg. One includes integration and training; another excludes both. One prices delivery to the buyer’s warehouse; another expects the buyer to arrange freight. The buyer is left trying to normalize ten different scope definitions, which is far harder than writing a structured RFP in the first place.

A well-constructed RFI or RFP inverts this problem. Instead of asking suppliers to guess what the buyer needs, the buyer defines the process, the environment, and the commercial requirements first. Suppliers then respond to the same scope, reducing scope ambiguity and making their quotations comparable on like-for-like terms.

The key principle: define the process before naming a robot type. If the buyer starts with “we need a cobot” or “we need an AMR,” the supplier conversation is already constrained by a product category that may or may not be the right fit. Starting with the task—what moves, how far, how often, in what environment, with what interfaces—allows the supplier to recommend the appropriate robot type, or to flag that the requirement falls outside their product range.

Define the Process Before Naming a Robot Type

Before writing any technical specification, the buyer should document the production or operational process that the robot will support. This means answering the following questions in concrete terms:

• What task does the robot perform? Machine tending, pick-and-place, palletizing, welding, assembly, cleaning, delivery, intralogistics transport. The task determines the robot family, the end-effector, the safety approach, and the integration scope.
• The current manual or semi-automated process matters because it establishes the baseline the robot must match or improve. Describe the existing workflow: who does what, in what sequence, with what tools, at what speed. This baseline allows suppliers to understand the process the robot must fit into, not just the task it must perform.
• Inputs and outputs define the interface boundaries. What arrives at the robot workstation (parts, pallets, containers, orders)? What leaves it? How are items presented—random orientation, organized fixtures, conveyor infeed, pallet stacks?
• The upstream and downstream processes determine whether the robot can operate continuously or must wait for manual or machine interfaces.

This process documentation does not need to be an engineering blueprint. But it needs to be specific enough that a supplier can understand the application without visiting the site. Vague descriptions like “handle boxes” are insufficient; “receive corrugated boxes from a conveyor at 600 mm height, pick with vacuum gripper, place onto a pallet pattern of 4 x 5, cycle time 8 seconds per box” gives the supplier enough to assess robot payload, reach, speed, gripper type, and integration requirements.

Required Technical Inputs: Part, Payload, Route, Cycle Time, Environment and Interfaces

Once the process is defined, the buyer needs to specify the technical parameters that determine robot selection. These inputs should be structured so that every supplier receives the same data set.

Part Characteristics

Payload and Reach

Payload is one of the most frequently misunderstood parameters in robot procurement. The buyer must confirm the manufacturer’s payload definition—whether it includes or excludes the end-effector/tool mass, center of gravity, dynamic limits, and required margin. The buyer should specify the workpiece weight separately and let the supplier calculate the required robot payload based on the manufacturer’s definition.

Reach (or working radius for articulated arms, or coverage area for mobile robots) determines whether the robot can access all required positions. For articulated robots, the buyer should specify the farthest pick point and place point, the height difference between them, and any obstacles in the work envelope. For mobile robots, the buyer should provide a layout drawing with pickup and drop-off locations, aisle widths, and turning clearances.

Route and Cycle Time

Environment

Environmental conditions directly affect robot selection, safety classification, and maintenance planning:

• Temperature range (the robot’s rated operating range vs. the actual site conditions)
• Humidity and washdown requirements (IP rating, stainless steel construction, food-grade compliance—applicable model/market dependent)
• Cleanroom classification (if applicable)
• Explosive atmosphere (ATEX zones, if applicable)
• Floor condition (flatness, load capacity, surface material—for mobile robots)
• Lighting (affects vision system performance)
• Noise restrictions (some environments limit robot noise output)

Interfaces

The interfaces that the robot must connect to—mechanically, electrically, and digitally—are often the difference between a smooth deployment and a stalled one. Buyers should list:

• Machines the robot will tend (CNC, injection molding, press, conveyor)
• Building systems the robot will interact with (elevators, automatic doors, fire alarms)
• Software systems the robot must integrate with (WMS, MES, ERP, BMS)
• Communication protocols available on site (e.g., Profinet, EtherCAT, Modbus TCP, OPC UA, REST API—confirm which apply to the specific robot/platform)
• Safety systems in place (light curtains, area scanners, safety PLC)

Site and Infrastructure Inputs: Layout, Power, Network, Elevators, Water, Safety

Beyond the robot itself, the site must be ready to receive and support it. The RFP should include a site readiness section that covers:

Layout and Space

• A dimensioned layout drawing showing the proposed robot workstation, material flow in and out, operator positions, safety perimeter, and maintenance access
• Available floor space (length x width x height)
• Floor flatness and load capacity (especially for heavy industrial arms or AGV/AMR routes)
• Ceiling height (for robot pedestal, end-effector clearance, or overhead utilities)

Power and Utilities

• Available electrical supply (voltage, phases, amperage, and whether a dedicated circuit is available)
• Compressed air (if pneumatic grippers or tools are needed)
• Water and drainage (for cleaning robots that need refill and wastewater discharge)
• Network infrastructure (Wi-Fi coverage, Ethernet drops, available IP addresses)

Elevators and Doors (for Mobile Robots)

If the project involves AMRs or AGVs that move between floors or zones, the RFP must specify:

• Elevator brand and model (the supplier needs this to assess integration feasibility)
• Door types (manual, automatic, fire-rated) and their control systems
• Aisle widths and turning radii along the planned routes
• Floor-to-floor height differences

Safety Infrastructure

• Current safety measures in the work area (fences, light curtains, area scanners)
• Whether a risk assessment has been conducted or is expected from the supplier
• Applicable safety standards depend on robot type, application, and jurisdiction. For industrial robots: ISO 10218-1:2025 and ISO 10218-2:2025 (internationally), ANSI/A3 R15.06-2025 (United States). For collaborative industrial applications: ISO/TS 15066:2016 within its scope. For driverless industrial trucks / many AMR applications: ISO 3691-4:2023. These standards must not be generalized to robot types or applications outside their scope.
• Whether the site has an EHS (Environment, Health, and Safety) team that must approve the deployment

Commercial Inputs: Quantity, Deployment Sites, Timeline, Support and Documentation

The commercial section of the RFP defines the project scope in terms that affect pricing, lead time, and supplier selection. Key inputs include:

Quantity and Phasing

• Total number of robots (or robot cells, or fleet size)
• Whether all units are deployed at once or phased over time
• Number of deployment sites (single site, multi-site, regional, or global)
• Expected rollout schedule (which site goes live when)

Timeline

• RFP response deadline
• Supplier selection target date
• PO issue date
• Delivery window
• Installation and commissioning window
• Go-live target

Support and Documentation

Destination Market Requirements

• Country of deployment
• Identify applicable regulatory/conformity, electrical/radio, labeling, and documentation requirements by product, model, configuration, and market. CE marking, UL listing, and FCC compliance are not universal certifications—they apply differently depending on the product type, configuration, and target market. The buyer should confirm which requirements apply to their specific robot and destination.
• Import documentation needs
• Packaging requirements
• Local language requirements for documentation and HMI

How to Separate Mandatory Requirements from Preferred Requirements

Not every requirement carries the same weight. Mixing mandatory requirements with nice-to-haves in a single list makes it impossible for suppliers to know what is non-negotiable and what is flexible. The RFP should clearly separate these two categories:

Mandatory Requirements (Must-Have)

These are requirements that disqualify a supplier if not met. Examples:

• Payload capacity of at least X kg (confirm manufacturer’s payload definition)
• Repeatability of +/-X mm or better
• IP rating of IPX or higher
• Compliance with applicable standards for the robot type and application
• Delivery within X weeks
• Support response time within X hours
• Ability to integrate with [specific system: WMS, elevator brand, PLC]

Preferred Requirements (Nice-to-Have)

These are requirements that add value but are not deal-breakers:

• Higher payload margin than minimum required
• Lower noise level than standard
• Extended warranty beyond standard
• Local language documentation
• Predictive maintenance capability
• Energy-saving features

The separation serves two purposes. First, it allows suppliers to respond honestly—if a supplier cannot meet a mandatory requirement, they can self-eliminate rather than submit a proposal that will eventually fail. Second, it gives the buyer a structured way to score preferred features as tie-breakers among suppliers that all meet the mandatory requirements.

How to Make Supplier Responses Comparable

Even with a well-structured RFP, suppliers will structure their proposals differently. To make responses comparable, the RFP should include a response template that requires suppliers to answer in a standardized format. At minimum, the template should include:

1. Technical compliance matrix: A table where the supplier confirms compliance (Yes / No / Partial) with each mandatory and preferred requirement, with a brief explanation for any “Partial” or “No” response.
2. Quotation breakdown: A standardized cost table with predefined line items (see table below), so that the buyer can compare line by line rather than comparing lump-sum figures that include different scopes.

• Assumptions and exclusions: A section where the supplier must explicitly list what is excluded from their quotation and what assumptions they have made. This prevents hidden exclusions from surfacing later as change orders.
• References: Project references with similar applications, including robot type, industry, payload/range, and deployment scale.
• Lead time breakdown: Engineering lead time, manufacturing lead time, shipping lead time, installation lead time—separately, not as a single “X weeks” figure.

When all suppliers respond in the same format, the buyer can compare technical compliance, cost breakdown, exclusions, and lead times on a level playing field. The comparison effort shifts from decoding different proposal structures to evaluating substance.

Robot RFI/RFP Checklist by Project Type

Different project types require different emphasis in the RFP. Below is a checklist that highlights which sections are most critical for common robot project categories.

This checklist is a starting point. Every project has unique requirements, and the RFP should be tailored accordingly. But the principle remains the same: the more structured and specific the RFP, the more comparable and useful the supplier responses will be.
