Beyond Industrial Robots: Why Humanoids Matter
Traditional industrial robots – articulated arms, gantries, and cobots – already perform vital roles in automated measurement, part handling, and inspection. However, their design constraints often limit their ability to operate flexibly in unstructured environments or to handle tools and equipment designed for humans.
Humanoid robots, by contrast, offer a unique advantages such as human-like mobility, cognitive adaptability enabled by AI and machine vision and compatibility with existing human tools, workstations, and metrology equipment.
These traits allow humanoids to integrate seamlessly into facilities where existing inspection setups such as CMMs, portable arms, laser scanners, and handheld probes are already in place. Instead of reengineering the factory floor, humanoid robots can work within it, acting as intelligent assistants or fully autonomous quality operators.
Automating Human-Driven Metrology Tasks
Many inspection tasks in manufacturing still rely heavily on human labor, not because automation is impossible, but because the variety and subtlety of operations make programming complex and costly.
For example:
- Loading and positioning parts for dimensional inspection on a CMM
- Using handheld laser scanners to capture freeform geometries
- Performing visual checks or surface defect detection
Humanoid robots equipped with advanced perception systems such as 3D vision, tactile feedback, and AI-based motion planning can perform these tasks autonomously. Their anthropomorphic form enables them to handle parts, operate metrology devices, and navigate around work cells designed for humans.
Early prototypes from companies such as Agility Robotics, Figure AI, and Tesla Optimus are already demonstrating the kind of locomotion and dexterity that could soon find use in smart factories, including inspection environments.
Hexagon has also recently entered the rapidly growing humanoid robotics market with the launch of AEON, developed by its Robotics Division. AEON has been specifically engineered to meet real-world customer needs and help address global labour shortages. The humanoid robot combines Hexagon’s world-class sensor suite with advanced locomotion, AI-driven mission control, and spatial intelligence, delivering exceptional agility, versatility, and situational awareness. This powerful integration enables AEON to perform a wide range of industrial tasks—from manipulation and asset inspection to reality capture and operator assistance.
A New Dimension – Cognitive Metrology
Humanoid robots are more than mechanical operators—they can also become cognitive metrologists. Powered by large AI models trained on inspection data, design intent, and process parameters, they can make context-aware decisions such as choosing the optimal inspection method for a given part geometry, reconfiguring inspection setups automatically, interpreting measurement results and identifying potential root causes of deviations and communicating results directly into the digital thread, updating CAD/CAM, PLM, or MES systems in real time.
When integrated into a digital twin of the production environment, humanoid robots could validate inspection routines virtually before execution, learning from simulation and real-world feedback alike.
Enhancing Flexibility in Smart Factories
In the next generation of manufacturing, flexibility is as valuable as precision. High-mix, low-volume production runs, increasing customization, and rapid design iteration demand inspection solutions that can adapt on the fly.
Humanoid robots can bring unprecedented flexibility to metrology automation by rapidly switching between inspection stations or tools, performing on-demand measurements without reprogramming, collaborating safely with humans in shared workspaces and filling in for human operators during off-shifts or labor shortages.
Unlike traditional automation that often requires dedicated fixturing or complex robotic cells, humanoid robots can use the same tools, reach the same work areas, and operate within existing infrastructure – a crucial advantage for retrofitting older factories into smart ones.
The Road Ahead – Hybrid Quality Control
The next decade will likely see hybrid quality control environments where traditional robots, humanoids, and AI-driven metrology software coexist. Humanoid robots could handle physical operations such as part loading, scanning, and probe exchange, while metrology software—integrated into the digital thread handles data analysis, process feedback, and adaptive correction loops.
In this collaborative ecosystem, humanoid robots act as the physical embodiment of AI turning digital intelligence into tangible action on the factory floor. Humanoid robots represent a paradigm shift in how smart factories might automate not just production, but the intelligence of measurement itself. By combining human-like versatility with robotic precision and AI cognition, they can transform metrology from a reactive process into a proactive, autonomous, and fully integrated function within the manufacturing ecosystem.
As the technology matures, the question may no longer be whether humanoid robots can perform metrology—but how soon they will become indispensable members of the digital factory workforce.
