AI-powered robots are already making an impact in various practical applications, such as Amazon's use of robots to streamline warehouse operations and AI robots that are optimizing farming practices in agriculture. Previously, we explored the overall role of AI in robotics and saw how it’s reshaping industries from logistics to healthcare. In this article, we'll dive deeper into why computer vision in robotics is so crucial and how it helps robots perceive and interpret their surroundings. 

The Importance of Vision Systems in Robotics

Vision systems in robotics act as the eyes of a robot and help it recognize and understand its environment. These systems typically use cameras and sensors to capture visual data. Computer vision algorithms then process the captured videos and images. Through object detection, depth perception, and pattern recognition, robots can identify objects, assess their surroundings, and make real-time decisions.

Vision AI or machine vision is essential for robots to operate autonomously in dynamic and unstructured environments. If a robot needs to pick up an object, it should be able to locate it using computer vision. That’s a very simple example. The same basic foundation of a computer vision system is needed to build applications where robots can inspect products in manufacturing or assist in medical surgeries with precision and accuracy. By providing the sensory input needed for real-time decision-making, vision systems make it possible for robots to interact more naturally with their surroundings and expand the range of tasks they can handle across various industries.

Recent Advancements in Computer Vision for Autonomous Robots

Recently, there has been a worldwide increase in the use of computer vision in robotics. In fact, the global robotic vision market is set to reach $4 billion by 2028. Let’s look at some case studies that show how Vision AI is being applied in real-world robotic applications to boost efficiency and solve complex problems.

Improving Underwater Inspections Using Vision AI and Robotics

Underwater inspections are vital for keeping structures like pipelines, offshore rigs, and underwater cables in good condition. These inspections help ensure that everything is safe and functioning properly to prevent costly repairs or environmental issues. However, inspecting underwater environments can be tough due to poor visibility, and hard-to-reach areas.

Robots with computer vision can capture clear, high-quality visual data that can be analyzed on the spot or used to create detailed 3D models of the areas being inspected. By combining human expertise with this technology, inspections become safer, more efficient, and provide better insights for maintenance and long-term planning.

For instance, NMS, a leading commercial diving company, used Blue Atlas Robotics' Sentinus Remotely Operated Vehicles (ROVs) for a challenging underwater pipe inspection with a murky entry point. The Sentinus ROV, equipped with computer vision, lit up the area with its fourteen lights and captured high-resolution images from different angles. These images were then used to create accurate 3D models of the pipe’s interior to help NMS thoroughly assess its condition and make informed maintenance and risk management decisions.

Constructing Houses with Vision AI and Robotic Precision

In the construction industry, maintaining consistent quality while dealing with labor shortages can be challenging. Automating construction with industrial robots offers a way to streamline the building process, reduce the need for manual labor, and guarantee precise, high-quality work. Computer vision technology can be integrated into this automation by making it possible for robots to perform real-time monitoring and inspections. Specifically, computer vision systems can help robots detect misalignments or defects in materials to double-check that everything is positioned correctly and meets quality standards.

An excellent example of this is the partnership between ABB Robotics and the UK-based start-up AUAR. Together, they are using robotic micro-factories equipped with vision AI to build affordable, sustainable homes from sheet timber. Computer vision enables the robots to cut and assemble materials precisely. The automated process helps with labor shortages and simplifies the supply chain by focusing on a single material. Also, these micro-factories can be scaled to meet local needs and support nearby jobs while making construction more efficient and adaptable.

Automating EV Charging with 3D Vision AI

EV charging is another interesting use case of vision AI in robotics. Using 3D vision and AI, robots can now automatically locate and connect to EV charging ports, even in challenging environments like outdoor parking lots. The vision AI works by capturing high-resolution 3D images of the vehicle and its surroundings, allowing the robot to accurately identify the location of the charging port. It can then calculate the exact position and orientation needed to connect the charger. Vision-enabled AI not only speeds up the charging process but also makes it more reliable and reduces the need for human intervention.

One example of this is Mech-Mind’s work with a large energy company. They developed a 3D vision-guided robot that can precisely find and connect to an EV’s charging port, even in tricky lighting conditions. Automated EV charging improves efficiency and charging in commercial spaces like office buildings and malls.
