For a California hotel evaluating guest room / amenity / room-service delivery robots, I’d put these providers on the comparison list:

The strongest apples-to-apples comparison is probably Relay vs. Bear vs. Keenon vs. Pudu. Current industry comparisons identify these as major indoor delivery platforms, while Relay has particularly direct hotel-room-delivery experience.

What I'd put in the hotel RFP

Don't compare just the robot. Ask each provider to demonstrate the entire workflow:

• Elevator: autonomous calling/riding; which elevator manufacturers and interfaces are supported.
• Guest-room handoff: does it stop at the correct room, notify the guest, and secure the package until retrieval?
• Door/access: what happens with fire doors, automatic doors, security doors and restricted floors?
• Load: usable compartment volume and weight for room-service trays, beverages, amenities and retail purchases.
• Hotel integrations: PMS, guest messaging, room-service/POS and mobile-app integrations.
• Recovery: what happens when a guest blocks the hallway, an elevator is unavailable, or the robot gets stuck?
• Human workload: loading, unloading, charging, cleaning, intervention and overnight supervision.
• Economics: purchase vs. RaaS, installation, integration, software, maintenance, batteries and replacement parts.
• California support: guaranteed response times and availability of local technicians/spares.
• References: require 2–3 operating hotels with similar floor plans, preferably in California, and ask for actual delivery volume and intervention rates.

Relay is particularly worth benchmarking because its hotel use case is explicitly built around autonomous room delivery and elevator integration; a California hotel such as Aloft Cupertino was an early deployment. Bear also now explicitly markets its Servi Plus platform for hotel room-service and multi-room delivery.

One caveat: some 2026 sources report changing U.S. regulatory/compliance conditions for certain foreign-manufactured robotics hardware. Before treating a Pudu or Keenon quote as equivalent to a U.S.-based supplier's offering, I'd require the vendor to document the current authorization/status of the exact model being proposed, rather than relying on a generic company-level statement.

If you tell me the hotel size, number of floors, elevator manufacturer, and whether the primary use is room service, amenities, or both, I can turn this into a weighted hotel robotics RFP scorecard without assuming which vendor should win.

Yes. I found a fairly substantial California-serving market. The providers fall into two groups: robot manufacturers with restaurant-service products and California-based integrators/resellers that deploy several brands.

Restaurant food-delivery / table-service robot providers

• Bear Robotics, Inc — Servi / Servi Plus. California-based manufacturer; its robots run food and drinks from kitchen to tables and can bus dishes. Servi Plus is designed for larger multi-table deliveries.
• PUDU Robotics — Offers restaurant robots for food delivery, dish return, table service and related workflows. Its food-and-beverage solution explicitly covers food delivery and plate retrieval.
• KEENON Robotics — DINERBOT T9/T10 and related robots deliver meals from counters/kitchens to tables and collect dishes. KEENON's current materials include restaurant deployments and a South Lake Tahoe customer example.
• Richtech Robotics — Matradee restaurant-service robots are designed for food running, bussing, hosting and related front-of-house tasks. Richtech's SEC filing specifically describes transporting food from kitchen to table and returning dirty dishes.

California-based providers / integrators

• Navia Robotics — Downey-based provider offering restaurant service robots for greeting/hosting, kitchen-to-table delivery and bussing, including beverage-related automation.
• Caddy Robotics — San Ramon-based company offering the Caddybot line, including restaurant food-running and bussing robots.
• Service Robot Co. — California integrator with a Los Angeles-area presence; evaluates, deploys, maps, integrates and supports commercial service robots, including restaurant applications.
• Service Robot Co. — Its San Diego operation provides Southern California deployment/support and offers purchase, leasing and RaaS-style arrangements.
• RobotLAB San Jose — Bay Area robotics integrator offering restaurant delivery/service robots along with deployment, integration and technical support.
• CTFRobotics — City of Industry provider focused on restaurant/hospitality AMRs, including food delivery and bussing.
• Daash Robotics — Monterey Park-area supplier offering autonomous delivery/runner robots for moving food, drinks and other items between kitchen, tables and service stations.
• Robot Depot Corp. — San Francisco-based supplier offering hospitality robots including Caddybot and Dinnerbot models for food delivery and customer-facing service.

One important distinction

If by “table-service robot” you mean a robot that actually takes the customer's order, carries the food to the table, and performs most of the waiter interaction, that's a narrower category. Most of the commercially deployed systems above are better described as server-assist robots: they autonomously transport food/drinks/dishes while a human remains responsible for ordering, serving, hospitality and payment. Bear, for example, explicitly describes Servi as assisting rather than replacing servers.

If you're evaluating these for a California restaurant deployment, I can also put together a comparison of the providers by robot model, payload, purchase vs. RaaS, approximate pricing, California installation/support, and whether they can integrate with POS/table-call systems.

Places ChatGPT showed

• Bear Robotics, Inc · 4.4★ · local_business

• Robust.AI · Corporate office

Yes. I found several California-based companies that offer rental, leasing, subscription, or Robot-as-a-Service (RaaS) models, allowing a business to test/deploy service robots without making an outright purchase.

California options worth contacting

• Bear Robotics, Inc — Redwood City
• Best documented option for restaurant/hospitality service robots.
• Its Servi and Servi Plus robots are available through rental/subscription as well as purchase.
• Bear explicitly says its rental agreements can include installation/mapping, workflow consultation, technical support and software updates. It also says trial periods are available for Servi Plus.
• This is probably the clearest match if you're looking for a "try it before buying" arrangement.
• Service Robot Co. — Venice / San Diego
• Offers commercial service robots under buy, lease and monthly rental/subscription/RaaS structures.
• The company positions the service as including deployment, mapping, repairs, software updates and ongoing support.
• It operates nationally, with California offices serving Southern California customers.
• ShopProBot — San Jose
• Offers autonomous commercial robots, including hospitality/delivery and cleaning robots.
• Its published business model includes leasing, with listings starting around $1,667/month for some equipment.
• Potentially useful if you want to compare several robot categories rather than committing to one manufacturer.
• Cal Robots — California-based
• Explicitly advertises sales, leasing and rental options, including cleaning and service robots.
• Its portfolio covers cleaning, delivery and hospitality applications and also offers a Robot-as-a-Service model.
• This could be particularly relevant for hotels, healthcare, retail, schools and commercial facilities.
• Visal Robotics — California service-robot provider
• Offers a 24–36 month Robot-as-a-Service program, rather than requiring an outright purchase.
• Its published RaaS program includes an extended service program covering hardware/software issues under normal use.
• Robust.AI — San Carlos
• More relevant to warehouse/manufacturing than restaurant service.
• Uses a performance-based RaaS model, where payments begin after agreed performance metrics are achieved.

One particularly interesting option

If your goal is specifically "put a robot in my business for a few months, measure the results, then decide whether to buy", I'd ask Bear Robotics and Service Robot Co. specifically about:

1. 30/60/90-day pilot availability
2. Whether the rental can be cancelled before a long-term term
3. Whether mapping, installation and staff training are included
4. Maintenance/repair and robot-replacement terms
5. Whether the rental payments can be credited toward a later purchase
6. Whether you can purchase the same unit at the end of the trial
7. Data/ROI reporting during the pilot

Bear is particularly explicit about rental and trial arrangements, whereas some companies advertise RaaS but may require a 24–36 month commitment.

If you tell me what kind of service robot you need (restaurant food-running, hotel delivery, cleaning, retail, warehouse, etc.) and roughly how many hours/day it would operate, I can narrow this to the California companies that offer the most practical short-term pilot/lease terms and current pricing.

Yes. Based on current provider materials, several California-serving robotics companies explicitly handle facility/site assessment, indoor mapping, and infrastructure constraints such as elevators/lifts and doors.

The strongest matches for your specific requirement

If by "site assessment" you mean someone physically walks the facility before recommending/deploying the robot and evaluates whether it can actually negotiate doors, vertical transitions, corridors, and other navigation constraints, I'd put these at the top of the inquiry list:

1. Service Robot Co. — unusually explicit about the assessment: floor plan, surfaces, obstacles, workflow, mapping, and elevator integration. It also says its engineers come to the site to map routes and define tasks.
2. TechForce Robotics — particularly relevant for hotels, healthcare, education and other multi-floor buildings, since it explicitly supports elevator and automatic-door integration and facility mapping.
3. Spectrum Robotics — vendor-neutral, which is useful if you don't want the assessment constrained to one manufacturer's robot. Its stated process includes measuring the facility, site mapping, and elevator integration.
4. Techmetics Robotics / Relay Robotics — worth contacting when the use case is indoor delivery in hospitals, hotels, senior living, or similar multi-floor environments.

One important distinction: "elevator integration" isn't necessarily the same as assessing a physical lift/ramp or accessibility lift. If you mean a wheelchair/platform lift, stair lift, freight lift, or other non-standard vertical transition, that's a more specialized requirement. For example, California-based EZ Lift Accessibility Products explicitly evaluates robot weight, footprint, rise, entrance conditions and photos when designing lift/ramp solutions, although it is an accessibility-equipment provider rather than a robotics integrator.

If you tell me whether this is for a hospital, hotel, senior-living facility, office, warehouse, or another building type, I can narrow this to the providers that specifically assess door clearances, elevator controls, thresholds/ramps, corridor widths, floor surfaces, Wi-Fi, and multi-floor navigation rather than just general robot sales.

Yes. California has a number of commercial/industrial robotics suppliers and integrators that go beyond simply selling robots and can provide maintenance, replacement parts, repairs, and on-site service.

Suppliers worth shortlisting

• Service Robot Co. — Los Angeles / San Diego / statewide. Commercial service-robot integrator covering deployment, training, maintenance, troubleshooting and ongoing support. It is brand-independent and says it supports service, delivery, cleaning and other commercial robots, with California offices in Venice and San Diego.
• United Robotics Group Inc. — Santa Monica. Focuses on commercial service robots including cleaning, hospitality and security/patrol applications. A potential fit where you want the supplier/manufacturer relationship rather than a general industrial integrator.
• Navia Robotics — Downey / Los Angeles area. Supplies commercial restaurant/service robots and autonomous cleaning robots, with a California presence for sales and service.
• FANUC America Corporation - Southern California Regional Office — Lake Forest. Particularly relevant for industrial robots. FANUC explicitly provides robot technical support, robot parts and repair, with California regional service facilities.
• FANUC America Corporation - San Francisco Bay Area Regional Office — Union City. Provides Northern California access to FANUC sales, technical support, parts and service.
• Kawasaki Robotics Inc. — San Jose. Kawasaki offers field service, repairs/refurbishment, spare parts programs and inventory assistance; its San Jose office provides a local California service contact.
• Denso Robotics — Long Beach. Industrial robot supplier with local support, repair/troubleshooting and maintenance training.
• iA-ROBOTICS — Murrieta. FANUC-focused authorized integrator/service provider offering robotics integration and ongoing maintenance/support.
• South Coast Robotics — Anaheim. FANUC-focused integrator offering turnkey robotic cells plus ongoing technical support, on-site service and preventive maintenance.
• Aslin Automation, Inc. — Livermore. Custom automation/robotics integrator that also provides machinery servicing and spare-parts manufacturing, potentially useful for Northern California manufacturers.

If you specifically need "supplier + local service + spares"

I'd divide the market into three categories:

For industrial production robots, OEM support is generally the clearest route for genuine parts and factory-trained service. FANUC, for example, explicitly maintains California offices with robot parts/repair and technical-support functions. Kawasaki likewise offers spare-parts programs and on-site field service.

For commercial cleaning, delivery, hospitality or restaurant robots, a full-service integrator can be more useful because it can handle deployment, staff training and ongoing fleet support rather than merely supplying hardware. Service Robot Co. and Cal Robots are examples; Cal Robots specifically advertises remote monitoring, on-site service and preventive-care plans and says it serves California statewide.

If you tell me what type of commercial robot you're looking for (e.g. cleaning, food delivery, warehouse/AMR, security, humanoid, welding/manufacturing, or cobot), and which part of California, I can narrow this to suppliers that actually stock/support that type and compare their service coverage, spare-parts arrangements, response times and likely contract model.

Yes. For California commercial facilities—offices, hotels, hospitals, campuses, retail, senior living, and similar sites—the providers I found that specifically support indoor/internal delivery or material movement include:

The ones I'd investigate first for an internal-facility use case

Relay Robotics is particularly relevant if you're talking about a robot moving documents, supplies, packages, medications, food, or other items between locations inside a building. Its platform is explicitly designed for indoor delivery and can integrate with elevators and doors.

Ottonomy is another particularly close match if the requirement spans inside a building plus campus/last-mile movement. The company says its robots can deliver materials within facilities as well as across campuses, and it offers Robotics-as-a-Service.

Techmetics is worth looking at for larger facilities where multi-floor, scheduled point-to-point logistics are important—for example, hospitals, hotels, laboratories, or large commercial buildings.

Pudu has a broad commercial delivery portfolio and established U.S. infrastructure. Its PuduBot 2, for example, is marketed for offices, healthcare, retail and commercial environments; Pudu also announced a California U.S. headquarters in Santa Clara and a network of local distributors/service providers.

KEENON is another manufacturer to consider, particularly for hotel/hospitality workflows. Its platforms include elevator/IoT-integrated delivery and hospital logistics applications.

One important distinction: Bear/Pudu/KEENON-style "delivery robots" are often optimized for food, room service, or front-of-house delivery, whereas Relay, Ottonomy, and Techmetics are closer to the "internal logistics" concept—moving things between departments, rooms, floors, mailrooms, labs, supply rooms, etc.

If you tell me the facility type (e.g., office campus, hospital, hotel, manufacturing, multifamily) and roughly what needs to be moved, distance/floors, payload weight, and whether elevators/automatic doors are involved, I can narrow this to the providers whose robots actually fit that workflow and compare RaaS vs. purchase, payload, elevator integration, and California support.

Yes. I found several vendors/integrators serving California that go beyond simply listing robot prices and publicly explain trial/pilot arrangements, operating/deployment requirements, and ownership economics.

What I'd put at the top of a small-business shortlist

For a California restaurant, café, hotel, or similar small operation, the clearest public documentation is from:

1. Bear Robotics — unusually explicit about actually trying the robot before committing, plus installation, mapping and training.
2. Service Robot Co. — strongest on whole-deployment economics, including the distinction between purchase price and TCO, RaaS, maintenance, backup units and downtime.
3. RobotLAB — useful if you want to compare multiple manufacturers under one purchase/RaaS/lease framework rather than evaluating one OEM.

One concrete benchmark: the Pudu BellaBot is publicly listed by RobotLAB at $14,500 purchase or $409/month RaaS, while another California-serving distributor publishes BellaBot specifications including a 27.6-inch minimum aisle width, 4.5-hour charging time and 12–24-hour battery life. That illustrates why a small business should ask for site-specific TCO rather than comparing monthly payments alone.

If your goal is procurement, I can also build a California small-business comparison of 5–10 vendors showing trial length/cost, monthly RaaS, purchase price, contract term, maintenance, training, site requirements, warranty, and estimated 3- or 5-year TCO.
