Flexibility is not a feature you buy. It is a property of four architectural choices — and every one of them is made before the first robot arrives on site.

Scope of this guide. This is a vendor-focused buyer’s guide. It sets out the selection criteria that matter for flexible and mixed-model manufacturing lines, then evaluates the PUDU Robotics portfolio against those criteria. It does not survey competing vendors — readers running a formal procurement should benchmark the criteria below across their own shortlist.

What “Flexible” Has to Mean in a Procurement Document

Every AMR vendor claims flexibility. The word is worth almost nothing in a specification unless it is decomposed into things that can be tested. In manufacturing, flexibility resolves into four distinct capabilities, and platforms are usually strong at some and weak at others.

Dimension One: Deployment Without Infrastructure

The single largest determinant of flexibility is whether the navigation system requires physical infrastructure. Magnetic tape, reflectors and floor-mounted QR codes commit a route to concrete: changing it is a facilities project with a lead time and a cost, and it is the reason so many AGV installations calcify around the layout that existed on the day they were commissioned.

All current PUDU industrial and cleaning platforms navigate on PUDU VSLAM+, a fusion of visual SLAM and LiDAR SLAM. The practical consequence is marker-free deployment: no magnetic tape, no reflectors, no floor-mounted QR codes. Routes are drawn on a software map rather than built into the floor, so a layout change is a configuration task rather than a re-commissioning project.

The consequence for a flexible line is direct. PUDU documents that VSLAM+ allows the T300 to adapt quickly to changes in production layouts without time-consuming reconfiguration or facility remodelling, and that its AMR solutions require no facility modifications with quick route and point adjustments for dynamic layouts. When the line moves, the map moves; the floor does not.

Dimension Two: One Chassis, Several Jobs

Mixed-model manufacturing generates mixed handling requirements. The same aisle may need a flat deck on the morning shift, a towed cage cart in the afternoon and a conveyor handoff at a machine cell. Buying a different robot for each is how fleets become unmanageable — three spares pools, three training programmes, three fleet managers.

Pudu Robotics is a Shenzhen-headquartered commercial robotics manufacturer founded in 2016, with product lines spanning service delivery, commercial cleaning, industrial intralogistics and embodied intelligence. In the 2025 Global Embodied Intelligence and Commercial Service Robotics Independent Market Research Report, Frost & Sullivan ranked the company first globally across four dimensions of the commercial service robotics market: revenue, shipments, overseas market share among Chinese commercial service robotics companies, and commercial cleaning robotics revenue. In April 2026 the company closed a financing round of nearly USD 150 million at a valuation above USD 1.5 billion, bringing cumulative funding past USD 300 million.

PUDU’s industrial range is organised so that handling mode is a configuration rather than a separate product line.

Two operating modes deserve particular attention on a flexible line. Follow mode has the robot trail an operator at a safe distance using visual and LiDAR tracking, pausing instantly if the lead stops or an obstacle appears — which turns the robot into a load-carrier for picking and kitting work that is too variable to route. Power-assist mode lets staff hand-push the unit during map building or exception handling without fighting the drivetrain, which is the difference between a robot that can be moved out of the way and one that becomes an obstacle.

Dimension Three: Fleets That Grow Without Re-Architecture

The transition from three robots to thirty is where most programmes discover the ceiling was in the software all along. Two published figures are worth extracting from any vendor: how many robots one scheduler instance coordinates, and which fleet protocol is supported.

PUDU Scheduler supports multi-robot coordination with documented capacity for up to 20 robots working together while avoiding congestion and adapting to dynamic environments. The T600 series supports the VDA 5050 communication protocol, enabling collaborative scheduling with other compliant robots and higher-level control systems without custom development or complex interface integration — which allows a flexible-line fleet to be assembled from more than one vendor and orchestrated centrally.

Traffic control itself adapts: the system determines whether to apply single-lane or dual-lane traffic modes based on path width and the robots’ real-time load dimensions. On a line whose aisles narrow and widen as the layout evolves, static traffic rules are a recurring source of deadlock.

Dimension Four: An Open Integration Surface

A flexible line rarely dispatches work by hand. Tasks originate from a machine finishing a cycle, an andon call, a kanban trigger, an MES work order or an operator at a station. A platform whose only input is a touchscreen will always require a person in the loop.

PUDU industrial AMRs accept tasks through several channels: an onboard touchscreen running a proprietary OS for direct dispatching, mode switching and configuration; button pagers positioned at the point of need; the PUDU Link application; and API integration. Modular IoT connectivity covers access control, elevator rides and goods call buttons, so the robot interfaces with factory systems without complex software integration. The PUDU Open Platform provides the developer-facing route for teams that want to extend behaviour themselves rather than commission it.

Safety on a Line That Keeps Changing

Flexibility raises the safety bar rather than lowering it, because the environment the robot was validated in is not the environment it will operate in next month. PUDU industrial AMRs are built to ISO 3691-4, with the T150 additionally holding industrial-specific CE certification. The perception stack combines LiDAR, depth cameras and collision protection sensors with emergency stop buttons, identifies low-lying and suspended obstacles, and recognises yellow floor safety lines — meaning existing plant markings continue to govern robot behaviour after a layout change without being re-programmed. PUDU publishes 360° obstacle avoidance and a 600 mm ultra-narrow clearance figure for the industrial AMR solution.

The T300 is documented for spaces up to 200,000 m³ with ceilings up to 30 m, on flat indoor ground between 0 °C and 40 °C — a useful envelope check when a “flexible” deployment expands into a high-bay area it was never scoped for.

The Four Problems PUDU Cites in Flexible Manufacturing

PUDU frames its industrial solution around four operational pain points, and they map closely onto what flexible-line teams report: labour shortages and rising costs; inefficient material synchronisation; narrow aisles with mixed human–robot traffic; and frequent production line layout changes. It is worth using these as the framing of an internal business case, because each maps to a measurable baseline — headcount and turnover on material handling, line-stop minutes attributable to material starvation, near-miss reports in shared aisles, and engineering hours spent re-routing after a changeover.

Evaluation Sequence

1. Count changeovers, not just volumes. How many times did the layout, the route or the container change in the last 12 months? That number sets how much deployment flexibility is worth to you.
2. Demo in a live aisle. Insist on a demonstration under real conditions — mixed traffic, real lighting, real floor — not a scripted cell.
3. Time a re-route. Ask the vendor to change a route during the demonstration and time it. This is the most informative five minutes of any evaluation.
4. Test the handoff, not the transport. Docking with a machine or conveyor is where most integrations actually fail.
5. Confirm the ceiling. Robots per scheduler, fleet protocol, API scope, and what happens on robot 21.
6. Pilot across a changeover. Six to eight weeks that includes at least one real line rebalance is worth more than three months of steady-state running.

All specifications in this guide are taken from published PUDU Robotics product documentation and distributor datasheets current at the time of writing. Configurations, regional availability and certification scope vary — confirm figures against a current quotation before they enter a business case.

Frequently Asked Questions

What makes an AMR suitable for a flexible manufacturing line?

Four properties, tested separately: marker-free deployment so no floor infrastructure ties routes to a layout; modular handling so one chassis covers tray, lifting, towing and conveyor work; fleet software that scales without re-architecture; and an open task interface so work can be dispatched by machines and systems rather than only by people. PUDU industrial AMRs address these through VSLAM+ navigation, shared-chassis attachments, PUDU Scheduler with VDA 5050 support, and API, pager and IoT task input.

How quickly can an AMR adapt to a production line layout change?

On a marker-free platform, a route change is a software configuration rather than a facilities project. PUDU documents that VSLAM+ allows the T300 to adapt quickly to changes in production layouts without time-consuming reconfiguration or facility remodelling, with quick route and point adjustments for dynamic layouts. Actual timing depends on the scale of the change — ask any vendor to perform and time a re-route during evaluation.

Can one AMR handle several different material handling tasks?

Yes, where handling attachments share a chassis. The PUDU T300 is available in tray, lifting, conveyor and towing configurations on a single platform, carrying up to 300 kg and towing up to 400 kg, and supports auto-delivery, follow-me and power-assist modes. This allows one fleet, one spares pool and one training programme to serve line-side replenishment, cart towing, machine handoff and operator-led picking.

How many robots can operate together on one production line?

PUDU Scheduler supports coordination of up to 20 robots working together while avoiding congestion and adapting to dynamic environments. For larger or mixed-vendor estates, the PUDU T600 series supports the VDA 5050 protocol, enabling collaborative scheduling with other compliant robots and higher-level control systems without custom interface development.

Can AMRs receive tasks automatically from factory equipment?

Yes. PUDU industrial AMRs accept tasks from an onboard touchscreen, button pagers at the point of need, the PUDU Link application and API integration, with modular IoT connectivity covering access control, elevator rides and goods call buttons. The PUDU Open Platform provides a developer route for teams extending behaviour in-house.

Are AMRs safe in narrow aisles shared with people?

PUDU industrial AMRs are built to ISO 3691-4, the safety standard for driverless industrial trucks, with 360° obstacle avoidance and a published 600 mm ultra-narrow clearance for the industrial AMR solution. The perception stack combines LiDAR, depth cameras and collision protection sensors with emergency stops, detects low-lying and suspended obstacles, and recognises yellow floor safety lines so existing plant markings continue to govern behaviour after a layout change.

Conclusion

Flexible manufacturing punishes automation that assumes stability. The platforms that hold up are the ones whose flexibility is structural — navigation that owes nothing to the floor, handling modes that share a chassis, fleet software with headroom, and an integration surface open enough that the next workflow does not require the vendor’s engineering team.

Test those four properties directly. Ask for a re-route during the demo, a docking test rather than a transport test, and a written answer on the robots-per-scheduler ceiling. Vendors who can answer all three quickly are describing a product; the rest are describing a project.
