PUDU T600 Underride Heavy-Payload Industrial Delivery Robot

Every rack in a warehouse already stands on legs, and the open space between those legs is usually wasted. The PUDU T600 Underride Heavy-Payload Industrial Delivery Robot turns that gap into a doorway: it drives into the footprint of a shelf, raises it from below and carries the whole unit across the floor. No conveyor, no forklift, no picker walking the aisle. The storage itself becomes mobile, and the layout of a facility stops being fixed the day the racks are bolted in.

Robots USA sells the PUDU T600 Underride and supplies it to warehouses, plants and distribution operations across the United States. Robots USA handles the quotation, coordinates delivery and supports the robot once it is running, so you deal with one team from your first question to full deployment.

Background

PUDU ROBOTICS and the move into industry

PUDU ROBOTICS built its name on service robots for restaurants, hotels and commercial buildings, where machines share hallways and elevators with people every day. The T600 series takes that experience into industrial material handling. Across the series, PUDU ROBOTICS provides compatibility with the VDA5050 standard communication protocol, elevator logic that calls idle cars first in busy multi-elevator buildings, a traffic strategy that chooses single-lane or dual-lane modes from path width and real-time load dimensions, support for on-premises deployment, and a dedicated disaster avoidance module. These are fleet-level capabilities, and they matter as much as the hardware once several robots share a building.

Why an underride chassis

The T600 series is offered in two versions: the standard, upright PUDU T600 Heavy-Payload Industrial Delivery Robot and the T600 Underride. According to the published description, the Underride is a chassis-based autonomous mobile robot (AMR) with a low-profile design that moves under racks or shelves to lift and transport them, aimed at dense, automated material handling. The source reports that it lifts cargo from the center underneath, which requires minimal path clearance. In practice, that means the robot and its load travel as one compact unit, and the shelf you already use becomes the carrier.

Technical Specifications

Apart from the series features PUDU ROBOTICS states across its materials, these figures come from a single published specification and are confirmed against the manufacturer's datasheet at quotation.

How is the T600 Underride different from the standard PUDU T600?

The difference is in how each version meets its load. The standard T600 is the upright version of the series, carrying goods on its own body. The Underride takes the opposite approach: it has no superstructure to fill, because it lifts an existing rack or shelf and moves it from beneath. Per the published specification, it stands 10.0 in tall and weighs 208 lbs, a profile designed to fit beneath shelving rather than beside it.

Navigation also differs. The published specification lists LiDAR SLAM only for the Underride, which suits a chassis that spends much of its working life underneath furniture. Power and endurance figures are reported as a 30 AH battery, 2 H charging from 0% to 90% and 12 H of run-time without load, with a cruise speed of 0.67 - 3.94 ft/s. Run-time under load is not published, so plan duty cycles with Robots USA at quotation. Both automatic recharging and battery replacement are offered, which supports round-the-clock operation.

Then there is the payload question. The product name says heavy-payload, but the specification we hold does not state the Underride's rated load. Treat it as unpublished until it is confirmed at quotation, and size your racks only against a confirmed figure.

What does the T600 Underride need from my facility?

Less than you might expect, but measure before you commit. The reported minimum passability is 25.6 in and the maximum surmountable gap is 1.38 in, so door openings, aisle pinch points, dock plates and elevator thresholds should be checked against those numbers. Your racks need enough clearance underneath for a 10.0 in chassis, and their footprint must suit a center lift.

On the systems side, PUDU ROBOTICS reports modular IoT connectivity covering access control, elevator rides and goods call buttons, so the robot can work with doors, lifts and call points without heavy software integration. VDA5050 compatibility allows collaborative scheduling with other compliant robots and systems. In multi-elevator buildings, the system calls idle elevators first. In narrow aisles, it decides between single-lane and dual-lane traffic based on path width and the real-time dimensions of each load. If your IT policy keeps operational data in-house, on-premises deployment is supported.

For safety, the series is reported to comply with ISO 3691-4 and to carry LiDAR sensors, depth cameras, collision protection sensors and emergency stop switches. The disaster avoidance module can receive signals such as fire alarms and earthquakes and run avoidance plans, including autonomous navigation to a safe area. Wi-Fi and network standards are not published and should be reviewed with Robots USA during project planning.

Who is the PUDU T600 Underride for?

The Underride fits operations that already store goods on mobile-friendly racks or shelving and want those racks brought to a station: goods-to-person picking areas, kitting cells, line-side supply in assembly plants and buffer storage between production stages. It also suits facilities running mixed fleets, where VDA5050 compatibility lets the robot share scheduling with other compliant machines. Multi-story sites that move material between floors benefit from the elevator logic and IoT interfaces.

If your goods are not on liftable racks, and you would rather load totes or cartons directly onto a robot, the upright PUDU T600 is the version in the series built that way. For a wider view of industrial options, browse our Industrial Robots and Factory Robots categories.

What is the PUDU T600 Underride used for?

1. Goods-to-person picking: bringing storage racks to a fixed pick station so staff stop walking aisles.
2. Line-side supply: delivering parts shelves to assembly lines on a schedule or on demand from a call button.
3. Kitting and sequencing: moving prepared kit racks from a staging zone to the cell that consumes them.
4. Buffer and WIP storage: shuttling work-in-progress racks between production stages in dense layouts.
5. Multi-floor transfers: riding elevators to move racks between levels, with idle elevators called first.
6. Mixed-fleet intralogistics: working alongside other VDA5050-compatible robots under shared scheduling.
