PUDU BellaBot is an indoor autonomous delivery robot designed for multi-table food and beverage service in restaurants, hotels, and commercial venues. It combines laser and visual integrated SLAM navigation for reliable indoor positioning. The cat-inspired chassis, built from ABS and aviation-grade aluminium alloy, earned the Good Design Award 2022. Four independent trays glide across uneven flooring thanks to a dedicated suspension system, while a triple RGBD camera array keeps guests and dishes safe.
| Specification | Why it matters |
|---|---|
| Battery Life: 12–24 h (hot-swappable 25.6 Ah pack) | Runs a full shift without a mid-service charging pause. |
| Tray Payload: 10 kg per tray × 4 trays | Carries several complete orders in a single delivery run. |
| Navigation System: Laser + Visual integrated SLAM | Keeps accurate positioning even when furniture moves or lighting changes. |
| Obstacle Detection Frequency: Up to 5400 times/min | Reacts to guests and staff crossing its path almost instantly. |
- Hot-swappable battery: Swap the 25.6 Ah pack in seconds instead of waiting through a 4–5 hour charge, so service never stops for a flat battery.
- Dual SLAM positioning: Laser mapping and visual marker anchoring work together, so the robot keeps its route even when tables are rearranged.
- Four independent smart trays: Each tray carries up to 10 kg and reports its own load status, letting one robot complete multi-table orders in a single trip.
- Triple RGBD camera array: A 0.5 s stop response and a detection arc beyond 192° reduce collisions in a crowded dining room.
Dual SLAM Navigation: Never Losing Track Indoors
Navigation reliability decides whether a service robot earns its keep on a busy floor. BellaBot runs laser and visual integrated SLAM (Simultaneous Localisation and Mapping) — two independent positioning methods working at once. The LiDAR unit builds a 360° map of the venue with centimetre-level precision, while the visual system anchors the robot to ceiling-mounted AR Markers for absolute position correction. Positioning stays accurate even when furniture is rearranged, sightlines to Markers are partially blocked, or ambient lighting shifts between service periods.
The scanning radius below shows how the LiDAR unit maps a fully occupied restaurant floor in real time.
Award-Winning Cat-Inspired Construction
Design in a service robot is not cosmetic — it decides whether guests engage with the machine or avoid it. BellaBot's cat-inspired silhouette, animated 10.1-inch LCD face, and soft-glow LED tray edges combine into a welcoming visual identity rather than an industrial one. This approach earned BellaBot the Good Design Award 2022.
The photograph below reflects the four tray levels, the animated LCD face, and the cat-ear head module that secured the award.
The shell is moulded from ABS reinforced by an aviation-grade aluminium alloy chassis, holding total weight to 55 kg while providing the rigidity needed for multi-shift commercial use across a rated 5-year service life.
The multi-angle collage below gives a full hardware reference — front profile, top-down head view, rear three-quarter, and the tray stack silhouette.
Advanced Suspension for Uneven Floors
Restaurant and hotel floors are rarely flat — tile-to-carpet transitions, expansion joints, and uneven grout lines create micro-obstacles that destabilise rigid-chassis robots. BellaBot's drive wheel assembly integrates a dedicated spring-damper suspension that absorbs vertical displacement up to 10 mm, so dishes stay level and filled glasses stay upright.
The cross-section below reveals the spring coil and damper geometry built into the drive module.
Intelligent Trays with Infrared Presence Sensors
Each of the four trays carries an infrared presence sensor that detects whether it is loaded or empty. With Tray Sensor Switch enabled, BellaBot ends the current table task automatically five seconds after the last dish is removed, needing no staff input. The modular quick-disassembly structure lets a tray be replaced in the field within seconds; each tray measures 410 mm × 510 mm and carries up to 10 kg.
The close-up below shows the glowing infrared sensor arcs built into the tray rim.
Swappable Battery for Continuous Service
Conventional service robots need a 4–5 hour charging pause between shifts. BellaBot's 25.6 Ah lithium pack slides out of the base unit in seconds, so a pre-charged replacement restores service immediately. Under mixed-activity conditions runtime spans 12 to 24 hours, and recharging a depleted pack takes 4.5 hours at 29.4 V / 8 A.
The photo below shows the extraction mechanism with the battery pack partially ejected from the base unit.
Three-Layer Safety Detection System
Triple RGBD Camera Array
The most hazardous obstacles on a restaurant floor are not furniture — they are moving legs, children below sensor height, and items left unexpectedly on the ground. BellaBot counters this with three front-facing RGBD (colour + depth) cameras in the lower chassis ring, detecting an obstacle and triggering a full stop within 0.5 seconds.
The close-up below shows the three RGBD apertures mounted in the blue accent ring at the base of the head module.
Detection Frequency and Range
Detection frequency determines how quickly the robot reacts to a chair pushed back or a waiter crossing its path. BellaBot's sensor stack refreshes up to 5400 times per minute — roughly one new scan every 11 milliseconds — across a front detection arc of 192.64° and a range beyond 10 m. This lets the robot plan an avoidance path well before an obstacle reaches minimum stopping distance.
The infographic below plots this refresh rate against the directional scanning cone projected ahead of the robot.
The coverage diagram below illustrates the full detection hemisphere and its 10 m-plus range.
Software, Automation and Fleet Intelligence
Six Operating Modes for Every Service Scenario
A restaurant's needs shift throughout the day — table service at lunch, promotional cruising during a lull, guest escorting at dinner. BellaBot switches between Delivery, Cruise, Direct Delivery, Birthday, Special, and Guiding modes from the on-board Android touchscreen, adapting to each scenario without reprogramming.
Multimodal Human-Robot Interaction
BellaBot's 10.1-inch LCD runs dozens of exclusive animated facial expressions — alert, happy, curious, sleepy, and several degrees of annoyance — triggered by operational state, touch input, or task completion.
The expression strip below samples the animation library, from wide-eyed alertness to a winking cat-eye look.
Each ear and the top of the head carries a haptic touch sensor. A single stroke triggers a friendly response, repeated touches escalate through more enthusiastic reactions, and excessive rapid touching produces a mild expression of displeasure.
The overhead view below shows the haptic sensor zones glowing on each ear.
Second-generation LED strips run along every tray edge and the base ring, cycling through patterns that signal tray-ready, task-active, charging, or error states without anyone reading a screen. Tray-level LEDs also mark which tray a guest should collect from.
The three-panel image below captures the emergency-area glow, tray-edge illumination, and cat-ear contour lighting side by side.
Multi-Robot Fleet Coordination
Multiple BellaBot units share positioning and task data over Wi-Fi, so each robot selects the nearest available pickup station automatically. If every station is occupied during a rush, units wait at temporary holding positions and move in the moment one frees up, preventing congestion at the kitchen pass.
The diagram below shows three units exchanging coordination signals across a restaurant floor.
Applications
- Restaurant table service: Delivers multiple orders to different tables in one run, using Delivery Mode's route optimisation to reduce staff walking distance during peak hours.
- Hotel room and lobby service: Guiding Mode escorts guests to a table or room, then returns automatically to its greeting point.

How to power on and start your first delivery with BellaBot
This procedure covers starting the PUDU BellaBot and running an initial table delivery in Delivery Mode. Confirm that the deployment map is configured and AR Markers are installed at the venue before beginning.
Step 1: Insert the battery and activate the key switch
Open the rear battery box cover, insert the 25.6 Ah hot-swap battery pack, and turn the key switch to ON. Close the cover securely — the power button will not respond until the key switch is on.
Step 2: Position the robot at the startup location
For visual or combined SLAM, move BellaBot directly beneath the first AR Marker, facing the main service direction. For laser-only SLAM, place the robot at the startup point marked on the configured map.
Step 3: Power on
Press and hold the power switch for 1 second. The bottom LED strip flashes, the screen shows the boot logo, and the Pudu App launches automatically after the startup animation. Tap the app icon on the desktop if it does not open.
Step 4: Select Delivery Mode
From the Pudu App main interface, tap the menu bar and select Delivery Mode. The screen displays the tray map and table number grid; tap Settings to adjust column count or enable multi-voice prompts before starting.
