The PUDU T600 Underride is an autonomous mobile robot (AMR) built for heavy-payload sub-rack transport in warehouses and factories. Its low-profile chassis slides beneath storage racks without structural changes, lifting entire rack assemblies for autonomous relocation. Native elevator control, e-gate access, and VDA5050 fleet scheduling enable unmanned, multi-floor intralogistics workflows.
| Specification | Why it matters |
|---|---|
| Maximum Load: 600 kg | Moves full rack loads in one pass, without secondary handling equipment. |
| Chassis Height: 255 mm | Slides directly beneath standard storage racks for true sub-rack transport. |
| Minimum Passability: 65 cm | Clears aisle widths that most competing AMRs cannot access. |
| Battery Life: 12 h (no load) / 6 h (max load) | Covers a full shift with margin, even at rated capacity. |
- Sub-rack chassis at 255 mm: the robot lifts and relocates entire rack structures, removing a full material-handling step from the workflow.
- LiDAR SLAM navigation: the robot maps and adapts to layout changes without ceiling markers, so re-deployment takes minutes rather than days.
- 65 cm minimum passability: standard 70–90 cm warehouse aisles remain usable even with loaded overhang.
- VDA5050 protocol compliance: the robot schedules alongside other compliant AMRs without custom middleware, cutting integration cost.
- Dual charging strategies: automatic docking and 60-second hot-swap keep the fleet running across shifts without manual battery-handling delays.
Construction and Chassis Design
The defining feature of the T600 Underride is its 255 mm chassis height. Conventional AMRs need elevated cargo platforms; this robot instead slides beneath existing rack structures, lifts from below, and transports the whole rack assembly autonomously. The 845 × 500 mm footprint matches standard rack dimensions common across European and North American distribution centers, so no facility modification is required.
The comparison below confirms that both platform variants — Standard and Underride — share the same 600 kg rated chassis, giving logistics teams a choice of deployment model without sacrificing payload capacity.
Removing the sub-rack handling step turns the robot itself into the motive force for the rack — a structurally simple approach that scales cleanly for high-density goods-to-person automation.
Rack Group Recognition and Docking Strategies
Sub-rack navigation requires more than raw LiDAR mapping — the robot must identify the correct rack within an identical group, dock precisely, and depart without contact damage. Two configurable arrival strategies handle this:
- Moving Backward: the robot reverses into the stop point, maximizing docking accuracy and repeatability.
- Direct Arrival: the robot drives straight to the target and adjusts heading in place, favoring faster cycles on open floors.
Integrators assign either mode per rack group based on aisle geometry, reserving the highest-precision strategy for the densest rack arrays.
Navigation and Narrow-Aisle Traffic
The T600 Underride relies solely on LiDAR SLAM (Laser Simultaneous Localization and Mapping) — no visual SLAM cameras, ceiling QR codes, or floor markers. The system builds and updates a geometric map continuously, tolerating repositioned racks or temporary blockages without a full remap. Deployment adapts to layout changes in minutes rather than days.
The 65 cm minimum passability width lets the robot work in aisle configurations many competing AMRs cannot enter. Across a standard 70–90 cm aisle, it navigates cleanly, even when loaded overhang extends slightly beyond the chassis footprint.
Intelligent Traffic Strategy
When several T600 units share a facility, aisle throughput becomes the bottleneck. The scheduling system monitors each robot's position and loaded dimensions in real time, then decides whether the current segment supports single-lane or dual-lane flow. Robots are never queued where two-way movement is safe; where loaded width would compromise clearance, single-lane priority is enforced automatically.
Tech Tip: Before the first deployment run, configure the loaded robot dimensions in Settings > Robot Functions > Run Setting > Total Width (Y) (500–1200 mm) and Rear Overhang (X) (0–400 mm) to match the actual footprint with an attached rack or cargo — the narrow-aisle strategy uses these figures to calculate dual-lane eligibility. Undersized values block dual-lane mode even when geometry permits it; oversized values force unnecessary single-lane routing. Treat mirrored or transparent surfaces at 14–22 cm height with matte stickers before deployment, since they can interfere with LiDAR-based localization at this operating height.
Software and Fleet Automation
Multi-floor logistics often stall at occupied elevators during shift peaks. The dispatch system tracks every elevator car in real time, routes robots to idle cars first, and cross-references travel distance with estimated wait time when several elevator banks are available.
Beyond elevator control, the robot connects natively to the wider IoT ecosystem:
- e-gate control for automated door and barrier access along robot routes
- pager call system for task dispatch via push-button terminals
- PUDU Link app for real-time monitoring and mission control from mobile devices
- peripheral hardware interface for custom facility systems and third-party WMS integration
- on-premises deployment via local server or private cloud for closed-network security
Safety Architecture
The T600 Underride operates alongside people and manually operated equipment. Its safety stack combines LiDAR for 360° mapping, downward-facing RGBD depth cameras for low-obstacle detection, and bumper sensors around the chassis perimeter for direct-contact protection; a front-facing camera adds forward-path awareness. All zones stay active simultaneously during travel.
Dynamic Obstacle Avoidance
At 255 mm chassis height, the LiDAR scan plane sits close to the floor, so low objects like debris or cardboard could theoretically pass beneath the primary beam. Downward RGBD cameras close this gap, triggering autonomous rerouting on a single robot without interrupting the rest of the fleet.
Disaster Avoidance
A dedicated module ties into building safety infrastructure. On receiving fire-alarm or seismic-sensor signals, the robot autonomously heads to the nearest safe parking zone or stops at the closest safe floor position, keeping evacuation corridors clear of cargo-loaded robots.
Runtime and Charging
A single T600 Underride runs 12 hours continuously under no load, and 6 hours at the full 600 kg rated capacity — enough for a standard shift with margin. The 30 Ah lithium-ion pack recharges to 90 % in approximately 2 hours, enabling shift-turnaround charging without manual battery handling.
Two charging strategies run side by side: automatic dock charging, where the robot navigates to the nearest available station once battery level drops below a set threshold, and manual hot-swap replacement, which keeps the robot powered for up to 60 seconds during the handoff. Both platform variants share the same charging station.
Fleet-Scale Monitoring
A coordinated fleet multiplies a single robot's value. The PUDU fleet management platform consolidates all T600 units across floors and buildings into one real-time dashboard, showing mission type, battery percentage, alert status, and floor position for every active robot.
VDA5050 protocol compliance lets the T600 Underride operate as a peer node within multi-vendor logistics ecosystems, scheduling alongside other compliant assets without custom integration work.
T600 Series: Underride and Standard Configurations
The Underride shares its 600 kg chassis rating with the T600 Standard, which adds a 10.1-inch touchscreen, a power-assist push handle, a forward safety contour projector, and hybrid VSLAM+LiDAR navigation. The Standard measures 960 × 500 × 1350 mm and weighs 112 kg, suited to surface-level cargo on external loading platforms above rack height.
The power-assist switch on the Standard model engages electric drive assist for manual repositioning — a feature absent on the Underride, which runs exclusively under autonomous or scheduled control.
Combined LiDAR, RGBD, and bumper coverage overlaps across both variants, with the Underride's ground-level perspective giving particularly dense low-obstacle coverage.
Applications
- Warehousing and distribution centers: sub-rack transport relocates loaded storage racks directly, cutting a handling step from goods-to-person workflows.
- Manufacturing facilities: the 600 kg payload rating moves heavy sub-assemblies and component racks between production lines.
- Multi-floor logistics sites: native elevator integration extends autonomous routes across building levels without manual escort.
- Mixed-vendor AMR fleets: VDA5050 compliance lets the robot schedule alongside other compliant platforms on one operations layer.
- High-density, narrow-aisle storage: 65 cm minimum passability keeps tight rack layouts usable without widening aisles.
- Double-shift operations: automatic dock charging and hot-swap batteries support continuous multi-shift throughput.
Compatibility of the PUDU T600 Underride
- Charging station: shares its automatic docking platform with the T600 Standard, letting one charging infrastructure serve mixed fleets.
- Storage racks: chassis footprint of 845 × 500 mm is sized for standard rack structures common in EU and North American distribution centers.

How to Start Up and Deploy the PUDU T600 Underride
Step-by-step procedure for initial power-on, dimension configuration, and first-deployment preparation, based on the official V1.1.1 Operation Guide.
Step 1: Initial Charge to 100 %
Before the first operational use, charge the battery to 100 % using the supplied charger or by docking at the automatic charging station. Insert the wired charger into the charging port, or select "Charge Now" in the PUDU scheduling UI for automatic dock charging. Avoid first commissioning on a partial charge.
Step 2: Power On the Robot
Press and hold the power switch for approximately 3 seconds until the chassis indicator lights turn blue, confirming the boot sequence is complete. For power-off, press and hold the same switch for 8 seconds — longer than the Standard version's procedure.
Step 3: Configure Loaded Dimensions
Navigate to Settings > Robot Functions > Run Setting and set the operating dimensions to match the loaded footprint. Set Rear Overhang (X) between 0–400 mm and Total Width (Y) between 500–1200 mm to reflect the actual dimensions with rack or cargo attached, since these values govern the narrow-aisle traffic strategy.
Step 4: Set the Brake Switch to ON
Verify the brake switch sits in the ON (I) position before autonomous operation, which engages drive-wheel braking for normal travel. Switch to OFF only when manually pushing the robot for maintenance repositioning — in OFF mode, the robot will not drive autonomously.
Step 5: Verify Emergency Stop Functionality
Press the red Emergency Stop button at the top of the chassis to confirm it halts the robot immediately. Rotate the button clockwise to release and restore normal operation before the robot enters a live working zone with personnel present.
Step 6: Dispatch the First Mission
With the robot powered on, dimensions configured, and brake engaged, dispatch the first delivery mission through the PUDU scheduling system or a compatible VDA5050 fleet platform. Monitor the run via the PUDU Link app or the web dashboard to confirm localization accuracy and docking performance.
