RH-12FRH
The RH-12FRH is a 4-DOF SCARA industrial robot manufactured by Mitsubishi Electric under the MELFA brand, designed for high-speed pick-and-place and assembly applications. It features a 12 kg payload capacity, 850 mm maximum reach, and 0.3 second cycle time, representing the third generation of the RH-FR series.
Overview and Use Cases
The RH-12FRH is a SCARA (Selective Compliance Assembly Robot Arm) industrial robot produced by Mitsubishi Electric Robotics as part of the MELFA product line. It is the successor to the RH-12SDH and represents the third generation in the RH-FR series. The robot is designed for autonomous execution of high-speed industrial tasks including pick-and-place operations and assembly work. Operation requires trained personnel for programming (teaching) and maintenance activities.

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.
