Run the Door-and-Elevator Test
Delivery robots move goods along a repeated route in a building or on a street. Pudu Robotics and Keenon Robotics build indoor platforms, Diligent Robotics targets hospital supply runs, and Serve Robotics operates outdoor sidewalk delivery.
The Bot Scout door-and-elevator test is the one that predicts deployments: list every door, elevator, badge reader, and locked area on the route, and name how the robot passes each one. Most indoor delivery projects stall on building infrastructure rather than robotics, and that integration is rarely in the robot's price.
The outdoor equivalent is the kerb. A sidewalk robot needs an operating area, crossings, a remote-assistance model, and a customer willing to come outside. Those terms define the service far more than the robot's payload does.
| Setting | Route characteristic | Integration that decides it | Most common blocker |
|---|---|---|---|
| Hotel | Room delivery from a front desk | Elevator control and staff dispatch | Guest unavailable at the door |
| Hospital | Supplies, linens, and medications | Access control and departmental handoff | Urgent corridor conflicts and secure areas |
| Campus | Scheduled runs between buildings | Outdoor segments and building entry | Weather and door access between buildings |
| Warehouse or industrial | Internal parts movement | Traffic rules with forklifts | Shared aisles at shift change |
| Sidewalk | Last-mile to an address | Operating area and remote assistance | Crossings, obstruction, lost connection |
Measure Handoffs, Not Deliveries
A completed delivery is not the same as work removed. Count every time a person loads, calls, escorts, unloads, rescues, cleans, charges, or restarts the robot, which is the handoff-count discipline used across the service robots hub.
Food service is a distinct problem with its own timing constraints and belongs in the food delivery robots guide. Hotel-specific requirements are in the hotel robots guide.
Pilot at the busiest hour with real traffic. A robot that completes every run at 2pm and none at shift change has not been tested against the conditions it was bought for.
- Map every door, elevator, and badge reader on the route.
- Confirm who pays for and installs the building integration.
- Count handoffs at both ends of each delivery.
- Define after-hours response and spare-unit availability.
- Pilot at peak, and record delayed and failed missions separately.
Security, Chain of Custody, and Liability
Anything valuable, controlled, or confidential raises questions a general-purpose delivery robot does not answer by default. Ask how the compartment locks, who can open it, whether the handoff is logged, and what happens to the load if the robot is stranded mid-route.
Public and semi-public spaces add accessibility and liability considerations that a warehouse deployment never faces. OSHA notes that many robot incidents occur during non-routine work such as setup, testing, and maintenance, which in a hospital corridor means the same space as patients and visitors.
The contract matters as much as the machine: mapping, staff training, monitoring, after-hours response, and spare units decide whether one fault ends the deployment.
Bottom Line
Delivery robots succeed where doors, elevators, and access control are solved and handoffs are short. Judge them on work removed at peak, and treat building integration as part of the purchase.
Map every door, elevator, and badge reader on one real route before booking a demonstration.
FAQs
What is the hardest part of deploying a delivery robot indoors?
Building infrastructure rather than robotics. Elevator control, door access, and badge readers usually decide the project, and that integration work is rarely included in the robot's price.
Do delivery robots work in hospitals?
They are used for supplies, linens, and medication transport. The deciding factors are access control, departmental handoff, chain of custody for controlled items, and behaviour during urgent corridor conflicts.
How is sidewalk delivery different from indoor delivery?
Sidewalk delivery adds an operating area, crossings, weather, a remote-assistance model, and a customer who must meet the robot outside. Those terms define the service more than payload or speed.
How should a delivery robot pilot be measured?
Count handoffs at both ends and record completed, delayed, and failed missions separately during the busiest hour. Deliveries completed at a quiet time say little about the deployment.
