Best for

High-capacity hotel delivery

Primary task

Room service and multi-point delivery

Environment

Hotels, restaurants, hospitals, offices and residential buildings

Deployment type

Mapped autonomous deployment with lift integration, SPARK site assessment, training and support

Handle bigger, busier deliveries without adding staff

Hotels and restaurants move large orders, linens and amenities across floors, often with hands full.

Large orders do not fit small robots

Bulky or multiple items need several trips.

Spacious storage.

T3’s 180 L storage capacity provides ample room for versatile deliveries, with up to 20 delivery points per run.

Staff carrying dishes cannot press buttons

Opening and closing robot doors with full hands is awkward.

Projection interaction

At the destination T3 projects a shape on the floor; a simple step triggers automatic door closure, keeping hands free.

Calling a robot takes too long

Staff and guests waste time finding or requesting the robot.

Smart paging solution

With a simple press of the pager, T3 comes straight to your location to be loaded.

How it works

KEENON T3

01.

Map or configure

Prepare T3 for your venue. Floors, rooms and lifts are mapped and integrated, and pagers are set up.

What the T3 handles
Uses LiDAR and stereo vision to map the venue and links with lifts.

Where people step in
Initial mapping and lift integration require human input.
The exact SPARK deployment process TBC

02.

Run the workflow

Staff page T3, load its storage and send it on its way. It rides lifts, delivers to up to 20 points and uses floor projection for hands-free doors.

What the T3 handles
Carries out multi-point delivery, lift riding, obstacle avoidance and auto-docking.

Where people step in
Staff load items and assign destinations; recipients collect from the cabin. Exact exception procedures TBC

03.

Monitor and improve

Keep deliveries aligned with demand, controlling T3 remotely and adjusting routes as needed.

What the T3 handles
Supports remote control and status monitoring.

Where people step in
People remain responsible for reviewing performance and deciding when adjustments, maintenance or further configuration are needed. TBC

Deployment and integration

From site survey to launch, SPARK prepares your robot for your site, your workflow and your team.

01 — Site survey

We assess your requirements and site conditions to help plan your robot deployment.

02 — Mapping

The operating area is mapped for autonomous operation before handover.

03 — Workflow design

We develop a deployment plan around your site and operational requirements.

04 — Integration

Integration requirements are assessed for each deployment, while tasks, schedules and reports are managed through the app.

05 — Training

SPARK provides user training as part of its after-sales support.

06 — Launch

Launch follows completion of site preparation, mapping, workflow setup and training.

Site Assessment

Understand the facility, floor types, traffic patterns and operational requirements.

Robot Deployment

Introduce the robot into daily operations with minimal disruption.

Mapping

Configure operating areas and routes according to the environment.

Remote Monitoring

Monitor robot operations and receive performance information through the app.

Training & Handover

Provide operators with the knowledge needed to manage the robot day to day.

Ongoing Optimization

Adapt maps and update software as the facility evolves.

Robot Deployment

Introduce the robot into daily operations with minimal disruption.

We are not a box shifter. Deployment covers site survey, mapping, workflow design, integration planning, training and launch — so your robot arrives configured for your building rather than dropped at your loading bay.

If the survey shows the robot is wrong for your site, we will say so.

upSPARK and ongoing support

From installation and user training to software updates and on-site maintenance, we provide full after-sales support.
