Hospital AMRs: Aethon TUG and Moxi in Clinical Logistics

Introduction to Hospital AMRs

Autonomous mobile robots (AMRs) deployed in healthcare facilities operate as material-handling and assistance systems rather than general-purpose humanoid platforms. The category is defined by navigation reliability, load capacity, battery endurance, and integration with hospital information systems. Deployment maturity in this sector is graded by shipped hardware units, clinical site installations, and validated operational metrics rather than concept demonstrations. Two systems dominate current commercial installations: the Aethon TUG series for logistics and the Diligent Moxi platform for patient and staff assistance.

Hospital AMRs navigate controlled indoor environments using laser mapping, visual-inertial odometry, and ultrasonic proximity sensors. They interface with existing elevator controllers, door access systems, and electronic health record workflows through standardized APIs. Procurement decisions in clinical settings prioritize uptime, infection control protocols, and return-on-investment calculations tied to labor displacement or task reallocation. This article examines shipping status, technical specifications, deployment data, and India market availability for these platforms.

Aethon TUG: Clinical Logistics Hardware

Shipping Status and Deployment Scale

Aethon TUG systems are classified as shipped commercial hardware. The platform was originally developed by Aethon Corporation and acquired by Getinge in 2019. Getinge reports cumulative deployments exceeding 6,000 units across hospitals in North America, Europe, and Asia. The hardware ships in standardized configurations with modular cargo carriers, including flatbeds, linen carts, lab transport trays, and medication dispensing modules. Deployment grading places TUG firmly in the shipping hardware category, with continuous production lines and established supply chains for replacement components.

Independent clinical evaluations and hospital procurement audits confirm that TUG units operate continuously on scheduled routes, executing material transport between pharmacies, central supply, laboratories, and nursing stations. Task completion rates and route optimization are managed through Getinge's Fleet Management software, which tracks robot status, battery levels, and task queue metrics. The system does not require facility modification beyond standard elevator integration and Wi-Fi coverage, which are typical for modern hospital infrastructure.

Technical Specifications and Safety Architecture

The TUG platform operates on a differential drive chassis with a maximum payload capacity of 136 kg (300 lbs) depending on configuration. Navigation relies on 3D laser scanning combined with visual markers and floor-level fiducials for precise docking. Battery systems use sealed lead-acid or lithium-ion options, delivering approximately 8 to 10 hours of continuous operation before automated charging. The robots comply with ANSI/RIA R15.08 safety standards for industrial robots and ISO 13482 specifications for personal care robots in terms of obstacle detection and emergency stop protocols.

• Drive system: Differential drive with caster steering
• Max speed: 1.2 m/s on open corridors
• Sensor suite: 360-degree LiDAR, stereo cameras, ultrasonic proximity, bumper arrays
• Navigation: SLAM mapping with fiducial calibration points
• Power: 24V DC system with automated docking charger
• Safety: ISO 13849 PLd performance level for control systems

Safety validation in clinical environments includes regular path verification, dynamic obstacle avoidance thresholds, and fail-safe braking. Hospitals typically conduct site surveys to map traffic patterns, door swing zones, and elevator call sequences before deployment. The hardware ships with pre-configured safety parameters that can be adjusted per facility layout, but core navigation logic remains factory-calibrated to prevent collision incidents.

Diligent Moxi: Patient and Staff Assistance

Commercial Deployment and Real-World Data

Diligent Moxi is classified as shipped commercial hardware with active deployment across select hospital networks. The system features a wheeled base with a mounted manipulator arm designed for item delivery and basic patient interaction. Diligent Robotics reports deployments in over 50 hospital sites in the United States, primarily in pilot-to-commercial transition phases. The platform is graded by shipped units and active site contracts rather than universal clinical adoption. Deployment metrics emphasize task execution reliability, patient satisfaction scores, and staff workflow integration.

Independent reporting and hospital procurement documents indicate that Moxi units operate on scheduled delivery routes for medications, lab specimens, and supplies. The robot's manipulator arm can open standard doors and press elevator buttons, enabling autonomous navigation through multi-floor facilities. Clinical staff interaction is limited to pre-recorded voice prompts and screen-based interfaces, with escalation protocols directing complex queries to human personnel. The system does not perform clinical procedures or handle hazardous materials.

Hardware and Navigation Specifications

Moxi operates on a robust wheeled chassis with a maximum payload capacity of 15 kg (33 lbs) for delivery tasks. The manipulator arm provides limited dexterity, optimized for grasping and releasing standardized trays and bags. Navigation utilizes a combination of laser scanning, visual odometry, and floor mapping. Battery systems deliver approximately 6 to 8 hours of active operation before automated charging. The platform complies with ISO 13482 safety standards for personal care robots and incorporates redundant braking systems for slope navigation.

• Drive system: Omni-directional or differential drive variants
• Max speed: 0.8 m/s in clinical environments
• Manipulator: 2-DOF arm with soft-grip end effector
• Sensor suite: 3D LiDAR, depth cameras, IMU, ultrasonic sensors
• Interface: Touchscreen display, voice synthesis, camera array
• Safety: Emergency stop buttons, collision detection, fall prevention algorithms

Deployment validation focuses on navigation accuracy, door interaction success rates, and task completion consistency. Hospitals typically conduct phased rollouts, starting with single-floor deployments before expanding to multi-level networks. The hardware ships with factory-configured navigation maps that require site-specific calibration for elevator integration and door hardware compatibility. Diligent Robotics provides on-site commissioning and remote monitoring support through its cloud management platform.
