C-Worker 4
The C-Worker 4 is a compact unmanned surface vehicle (USV) manufactured by L3Harris ASV, measuring 4.2 meters in length with an aluminium hull and diesel-powered propulsion. Designed for coastal and offshore survey operations including hydrographic, oceanographic, and environmental missions, it offers up to 48 hours endurance and supports both remote control and autonomous waypoint-following modes.
Overview and Use Cases
The C-Worker 4 is a compact USV developed for survey and monitoring operations in coastal and offshore environments. Primary use cases include hydrographic surveys, oceanographic research, and environmental monitoring. The system has been deployed by academic institutions including the University of Plymouth for research applications.

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.
