Gavia AUV
The Gavia AUV is a modular, man-portable autonomous underwater vehicle manufactured by Teledyne Marine, rated to depths of 500 m or 1000 m and configurable between 1.8–4.5 m in length. Developed by Teledyne Gavia (founded in Iceland in 1999 and acquired by Teledyne Technologies in 2010), it is deployed across military, commercial, and scientific applications including mine countermeasures, search and rescue, and subsea surveys.
Overview and Use Cases
The Gavia AUV is a torpedo-form autonomous underwater vehicle designed for autonomous execution of survey missions without real-time human control. It is deployed across multiple sectors:
- Military: Mine countermeasures (MCM), anti-submarine warfare (ASW) training; adopted by 18 navies, including the Swedish FMV
- Commercial: Subsea infrastructure inspection and offshore survey operations
- Scientific: Geophysical surveys and oceanographic data collection
- Search and Rescue (SAR): Autonomous search operations
Key Capabilities
The Gavia AUV operates autonomously and is man-portable, enabling rapid deployment in field conditions. Key operational features include:
- Modular construction: Reconfigurable in length (1.8–4.5 m) and mass (50–130 kg) to suit mission requirements
- Depth rating: 500 m or 1000 m variants
- Endurance: 5–8 hours at 3 knots cruise speed
- Maximum speed: Greater than 5.5 knots
- Communications: Acoustic modem and Iridium satellite link for mission coordination and data relay

RobotRelay Delivery Robot
The Relay Delivery Robot is an autonomous indoor delivery robot developed by Relay Robotics (formerly known as Savioke), designed primarily for hospitality and healthcare environments. It navigates hotel corridors and hospital hallways independently, rides elevators without human assistance, and delivers guest amenities, medications, linens, and other supplies directly to rooms or designated drop-off points. Relay is one of the most widely deployed service robots in its category, reportedly completing over one million lifetime deliveries with a publicly cited success rate of approximately 99.8%. With a cargo capacity of around 10 gallons, the robot is compact enough to operate in busy public spaces while carrying a meaningful payload of everyday supplies.

RobotSpot
Spot is a four-legged autonomous robot developed by Boston Dynamics, a robotics company headquartered in Waltham, Massachusetts. Designed for inspection, security, and data collection in complex or hazardous environments, Spot can navigate stairs, rough terrain, and confined spaces that are inaccessible to wheeled robots. It is commercially available and has been deployed across industries including utilities, oil and gas, construction, and public safety. Spot supports a modular payload system that accommodates thermal cameras, pan-tilt-zoom (PTZ) cameras, lidar units, methane sensors, and other mission-specific hardware. Boston Dynamics also offers the Orbit fleet-management software platform, enabling operators to schedule autonomous inspection routes, aggregate sensor data, and manage multiple Spot units from a central interface. The robot is widely regarded as one of the most capable and commercially mature legged robots on the market.

RobotRealSense Depth Camera D455
The RealSense Depth Camera D455 is a stereoscopic active-infrared depth camera belonging to Intel's D400 series, designed to capture high-fidelity depth data for robotics, autonomous mobile robots (AMRs), drones, and computer-vision applications. It features a 95 mm stereo baseline — the widest in the D400 lineup at the time of its introduction — which reportedly enables depth error of under 2% at ranges up to approximately 4 metres. Originally developed under the Intel RealSense brand, the D455 and related products were later spun off as part of an independent RealSense business unit following Intel's restructuring of the division around 2021–2022. The camera is widely adopted in research, industrial automation, and humanoid-robot development owing to its compact USB-powered form factor, open SDK support, and relatively accessible price point.
