PUDU FlashBot – Smart Hotel & Office Delivery Robot

PUDU FlashBot is an autonomous delivery robot designed for multi-floor hotel and office deliveries. It calls and rides building elevators through IoT integration, removing the need for a staff escort. Modular lockable compartments and LiDAR-based navigation let it move safely through crowded lobbies and corridors.

• IoT elevator integration: The robot calls, boards, and exits lifts on its own, so deliveries reach any floor without a staff member riding along.
• Independent compartment locking: Only the bay assigned to a destination unlocks, letting one multi-drop run serve several rooms without mixing orders.
• UV self-disinfection: Built-in UV lamps sanitise each bay between drops, keeping room-service items hygienic without extra staff handling.
• Independent wheel suspension: Coil-spring suspension at each wheel keeps trays level across thresholds and carpet-to-tile transitions, protecting fragile items like glassware.

Built for Vertical Buildings: Hotels, Offices, and Towers

Most delivery robots stop at the lobby doors, but the FlashBot travels between floors on its own. Fused PUDU SLAM and VSLAM+ positioning, together with IoT-linked building systems, let the chassis handle hotel corridors, marble lobbies, and carpeted guest floors. Deliveries of room-service items, parcels, and amenities move without a human escort at any stage.

The paired studio view below highlights the robot's carbon-weave body and yellow side panels, a design built on an aluminium-alloy and engineering-plastic frame.

In hospitality settings, the robot's design language fits naturally into premium interiors rather than reading like a warehouse machine.

Autonomous Elevator Navigation via IoT

The core technical differentiator is the FlashBot's ability to call, board, ride, and exit elevators without human intervention. A cloud-based IoT connection lets it communicate directly with elevator control systems: it dispatches a car, waits for the doors, selects the destination floor, and exits at the right corridor. The same IoT layer links to phone systems and access control, turning the robot into a central node of a digitally managed building network.

The corridor photograph below captures the robot approaching an elevator bank, its indicator strip glowing as it nears the call point.

Security Turnstile and Access Control Integration

In gated office lobbies, the IoT module extends to security turnstiles. This "Internet of Everything" architecture lets the FlashBot move fluidly across reception, security checkpoints, and floor corridors without requiring staff to override access controls.

The lobby scene below shows several PUDU robots, including a FlashBot, passing through flap-barrier turnstiles on their way to a waiting elevator.

Modular Compartment System: 2–4 Bays, Up to 30 kg Payload

The storage architecture is configurable: the body supports 2 to 4 lockable compartment bays, each with a single-tray interior of 219 × 410 × 286 mm, or a double-width layout of 438 × 410 × 286 mm using a removable partition. Maximum total payload is 30 kg, with each tray rated for 15 kg. White interior lamps illuminate the contents, and a UV lamp per bay runs autonomous disinfection during delivery and standby. Each bay is addressed independently — the robot opens only the compartment matching the recipient's destination, so a single run can serve several rooms as a parallel delivery event rather than a sequence of separate trips.

Independent Suspension for Smooth Threshold Crossings

An upgraded independent suspension sits at each wheel position, keeping the load platform level as the robot crosses floor obstacles up to 20 mm high and gaps up to 35 mm wide. That stability matters for fragile amenities — a glass of water or a folded towel stays upright across door thresholds and carpet-to-tile transitions.

Guest Interaction: Greeting and Escort Modes

Beyond pure delivery, the FlashBot runs two guest-facing modes. In greeting mode it interacts by voice, offers check-in guidance with optimal path planning, and can escort visitors to a floor or room; in escort mode it leads guests through the building at a comfortable pace, adjusting its route around crowds. A 10.1-inch LCD screen and a 10 W stereo speaker carry announcements, directional cues, and brand messaging, making the robot a customer touchpoint as well as a logistics tool.

The scene below shows a family with a child and rolling luggage interacting naturally with the robot as it passes through a bright lobby.

UV Compartment Sterilisation

Each compartment bay carries a UV lamp operating in the 260–280 nm germicidal wavelength range. The disinfection cycle runs automatically during delivery and standby once activated in the settings interface, giving a hygienic handoff from housekeeping to guest room without contact handling.

The photograph below shows both compartment tiers open and lit by UV light, with folded towels and linens visible inside.

Last-Mile Precision: Door-Level Delivery

The FlashBot's routing logic takes it to the specific door matching a compartment's destination, not just the floor. Only the compartment assigned to that room unlocks on arrival; every other bay stays sealed, which prevents cross-contamination between deliveries and protects guest privacy on multi-drop runs.

The photograph below shows the robot waiting outside a numbered room door, its indicator ring lit, ready to notify the guest through the in-room phone system.

Build Quality and Visual Identity

The enclosure pairs high-quality industrial plastic panels with an aviation-grade aluminium alloy frame, keeping weight manageable at 55 kg while giving the impact resistance needed for daily operation in busy lobbies and corridors. The yellow side accents and carbon-weave panel make the robot instantly identifiable as a service presence rather than an obstacle.

The product study below isolates the design, making the side-pillar architecture, LiDAR aperture, dual RGBD camera positions, and indicator strip clearly visible.

Applications

• Hotels and resorts: Handles room-service deliveries, amenity requests, and in-house takeaway orders floor-to-floor without a staff escort, freeing front-of-house teams for guest-facing tasks.
• Corporate office towers: Moves documents, mail, and small packages between departments across multiple floors, including through security turnstiles in gated lobbies.
• Multi-tenant office buildings: Consolidates deliveries from several tenants into one multi-drop run, using independent compartment locking to keep each recipient's items separate.
• Serviced apartments and residential towers: Delivers parcels and linen directly to unit doors, with UV disinfection running automatically between drops.
• Conference and events venues: Escorts visitors to meeting rooms or exhibition floors using its guest-interaction mode alongside standard delivery runs.

How to Perform the First Room Delivery with the PUDU FlashBot

This procedure walks through powering on the FlashBot, loading a delivery, and dispatching the robot to a guest room for the first time.

Step 1: Power On the Robot

Push the robot to the startup positioning location, typically the charging station. Turn the key switch to the ON position, then press and hold the on/off switch for approximately 0.5 seconds. Wait until the logo indicator turns blue and the 10.1-inch LCD screen lights up before proceeding.

Step 2: Access the Delivery Interface

Tap the "Delivery" icon on the touchscreen. Enter the initial operator password (default: 0000) when prompted. The delivery interface opens, showing available compartments and destination entry fields.

Step 3: Load Items and Set the Destination

Open the appropriate compartment door and place the items inside, keeping within 15 kg per tray and the 30 kg total payload limit. Do not place unpackaged liquids, high-temperature objects, or flammable materials in the compartment. Enter the target room number or floor destination on the touchscreen.

Step 4: Start the Delivery Run

Tap "Start." The FlashBot closes its compartment doors, plans the optimal route using PUDU SLAM positioning, navigates corridors autonomously, calls the elevator via IoT if required, and travels to the destination floor and room. On arrival it notifies the guest through the integrated phone system.

Step 5: Guest Retrieves the Delivery

Only the compartment assigned to the destination room unlocks on arrival; all other compartment doors stay sealed. After the guest retrieves the items and closes the door, the FlashBot proceeds to the next drop-off on a multi-drop run or returns autonomously to the charging station for a top-up charge.

Frequently Asked Questions

Can the PUDU FlashBot call and ride elevators without staff assistance?

Yes, the FlashBot uses IoT integration through a cloud-based network connection to communicate with the building's elevator control system. It calls a car, waits for the doors, boards, selects the target floor, and exits entirely on its own — no staff escort is required at any point.

What is the maximum payload capacity of the FlashBot?

The FlashBot carries a maximum total payload of 30 kg, distributed across 2 to 4 modular compartment bays. Each tray is rated for 15 kg. The partition between adjacent bays can be removed to form a double-width compartment of 438 × 410 × 286 mm for larger items.

How long does the FlashBot battery last and how does the robot recharge?

The FlashBot runs for up to 12 h on a single charge from its 15.6 Ah / 396.396 Wh battery pack. Recharging takes approximately 4.5 h. The robot supports manual charging via a cable and fully autonomous auto-docking at a charging station, triggered by a screen tap or automatically once the battery drops to 20%.

Does the FlashBot disinfect its compartments automatically?

Yes, each compartment bay is fitted with a UV lamp operating at 260–280 nm germicidal wavelength. Once disinfection is enabled in the settings interface, the robot runs autonomous UV cycles inside the compartments during active delivery runs and while on standby at the charging station.

What corridor width does the FlashBot require to operate safely?

The FlashBot needs a minimum corridor width of 70 cm to pass and a minimum turning clearance of 75 cm. A width of 1 m is recommended for long hotel corridors, and 2 m allows two units to operate simultaneously in opposite directions. The maximum operating slope is 8°, with a recommended working slope under 5°.
