NAO V4
NAO V4 is a small humanoid robot standing 574 mm tall and weighing 5.48 kg, developed by Aldebaran Robotics and later operated under SoftBank Robotics Europe. The platform has been deployed in over 70 countries with more than 20,000 units sold, primarily for education, research, and healthcare applications.
Overview and Use Cases
NAO V4 is a compact humanoid robot originally developed by Aldebaran Robotics (Paris, France). Following Aldebaran's 2025 liquidation, the platform is now continued by NAO Robotics SA. The robot has achieved significant global deployment, with installations in 70+ countries and cumulative sales exceeding 20,000 units.
Primary deployment contexts include educational institutions, research laboratories, and healthcare facilities. The platform supports autonomous task execution following human programming and configuration, but does not perform open-ended tasks without explicit human setup and instruction.
Key Capabilities
- Programmable through multiple development environments: Choregraphe, Python, and C++
- Executes pre-programmed and scripted tasks autonomously once configured
- Performs tasks defined by human operators; does not perform open-ended autonomous activities
- Designed for interactive and educational demonstrations
Specifications
- Height: 574 mm
- Weight: 5.48 kg
- Degrees of Freedom: 25 DoF (manufacturer specification); 26 DoF per technical sheet joint breakdown
- Category: Humanoid robot
Applications
NAO V4 has been deployed across three primary sectors:
- Education: Used in schools and universities for teaching robotics, programming, and human-robot interaction
- Research: Deployed in academic laboratories for studies in robotics, artificial intelligence, and behavioral sciences
- Healthcare: Implemented in clinical and therapeutic settings for patient interaction and support applications
Manufacturer
NAO V4 was originally developed by Aldebaran Robotics, headquartered in Paris, France. The product line was subsequently operated under SoftBank Robotics Europe before transitioning to NAO Robotics SA following Aldebaran's liquidation in 2025.
Current market offerings include the NAO6 model, available at price points ranging from approximately $16,990 to $19,990 for new units. Robot-as-a-Service (RaaS) options are available through RobotLAB.

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.
