9 Operational Modes: From Table Service to Live Marketing

KettyBot ships with nine distinct function modes pre-loaded on its Android operating system. Each mode is purpose-built for a specific service scenario, which means you can deploy the same unit across completely different tasks throughout the day without any hardware reconfiguration.

  • Guiding — escorts customers to their assigned table or to a specific product area
  • Birthday — initiates a celebratory routine for special occasions
  • Customer Attraction — travels to defined greeting points and engages passers-by autonomously
  • General Delivery — standard item transport for non-restaurant environments
  • Delivery — restaurant-optimised multi-table delivery with tray confirmation
  • Advertising — cruises predefined routes while playing promotional content on the 18.5-inch screen
  • Cruise — continuous loop patrol along a set route (up to 10 routes supported)
  • Dish-Return — collects used tableware from tables and transports it to the kitchen
  • Table Services — responds to table-side service requests

Available in two distinct colour variants — Vibrant Yellow and Classic White — KettyBot can be matched to your venue's brand identity. The colour choice also determines hardware capabilities: the Vibrant version and units with self-developed core boards support 4G SIM cards for remote management.

Hybrid SLAM Navigation: Laser + Vision in Crowded Spaces

KettyBot combines LiDAR point-cloud mapping with visual depth sensors to build and maintain a dynamic floor map in real time. This dual-sensor SLAM approach — rather than LiDAR alone — gives the robot resilience against transparent surfaces, reflective floors, and moving obstacles. The minimum passage width of 55 cm means it can navigate between tightly packed restaurant tables without requiring layout changes.

Depth vision sensors and a front positioning camera continuously scan the environment at floor level, while the 3D obstacle detection system triggers automatic path recalculation rather than a full stop. The following image shows KettyBot operating autonomously in a real restaurant environment, navigating freely between tables and chairs.

18.5-Inch Advertising Screen: A Moving Digital Billboard

Every delivery run is also a marketing event. The large 18.5-inch LCD advertising screen supports both image slideshows and full video playback (up to 300 MB storage, up to 10 separate ad materials). Content is managed remotely via the Merchant Management Platform (browser-based) or through the Pudulink mobile app — no on-site technician required. You can schedule different content for different cruise waypoints: table A sees a drinks promotion, table B sees today's specials.

Three-Level Delivery Architecture: Trays + Dish-Return

The rear of the KettyBot houses a modular tray system: two removable delivery trays (each rated at 10 kg) plus a dedicated dish-return box at the base. The tray spacing — 248 mm / 253 mm / 223 mm from top to bottom — accommodates standard restaurant plates, bowls, and covered dishes. Each tray measures 352 mm × 340 mm, providing adequate surface area for simultaneous multi-dish delivery to a single table.

The image below shows the KettyBot's rear tray compartment open, with both delivery shelves and the dish-return box visible, all illuminated by the robot's interior accent lighting.

Dual Display System and 6-Microphone Voice Interaction

Beyond the large advertising panel, KettyBot features a secondary 10.1-inch LCD screen for customer interaction — confirming delivery status, displaying table numbers, or presenting interactive menus. The Android-based OS runs both screens simultaneously without performance degradation. Voice interaction is handled by a 6-microphone circular array backed by 2 × 10 W stereo speakers, giving the robot a clear, directional voice presence in noisy dining environments.

The yellow variant's 10.1-inch LCD screen is shown below, displaying a colourful interface — this is the primary interaction panel that customers face during escorting and greeting routines.

The white variant's refined profile is shown below — the smooth, seamless casing is constructed from ABS and aviation-grade aluminium, providing a premium visual aesthetic suited for hotel lobbies and upscale dining venues.

Expert Verdict: For hospitality operators looking to automate repetitive service tasks, KettyBot offers a commercially proven combination of delivery logistics and in-venue marketing. The dual laser-visual SLAM system outperforms single-sensor navigation in environments where glass partitions, mirrored surfaces, or constantly rearranged furniture are common. One operational tip: always configure greeting points before activating Customer Attraction mode — without them, the mode will not initiate. For multi-robot deployments, use Settings → Map Settings → Select Charging Pile to pair each unit with its dedicated dock and avoid charging conflicts during peak service hours.

The complete side profile below shows the full height of the KettyBot (1120 mm), with the advertising screen, both delivery trays, the dish-return box, and the drive wheels all visible. This view confirms the robot's compact footprint of 435 mm × 450 mm — critical for manoeuvring in tight floor plans.
