Robotic inspection devices in the industrial sector are getting more critical to all manufacturing, oil & gas, power generation, mining, aerospace, logistics, and infrastructure industries. Robots assist firms in examining dangerous, difficult-to-reach locations, and those requiring repetitive tasks. With more than 4.6 million industrial robots running worldwide by 2024, robotics inspection devices have become more common in predictive maintenance programs.

Ground-Based Mobile Inspection Robots
Among the inspection systems in manufacturing plants and factories, ground mobile robots are considered one of the most extensively utilized ones. These autonomous robots are capable of inspecting production floor areas, warehouses, tunnel structures, and utility passages employing cameras, LiDAR technology, thermal cameras, and machine learning analytics. In the manufacturing industry, such robots are employed for conveyor belt testing, detecting overheating issues, and monitoring mechanical vibrations.
In automobile and electronic factories, robot-driven inspections are expected to ensure more consistent defect detections, saving time in manual inspection processes by 50%. Autonomous mobile robots are utilized in many smart factories around the clock in off-hours shifts.

Aerial Drone Inspection Robots
Aerobotics is widely employed in energy, utility, telecommunications, and construction industries. Drones check power lines, oil rigs, wind mills, bridges, and tanks that may pose risks or costly operations for humans. Drone technology utilizes high-definition camera and infra-red vision, ultrasonic scanning capabilities, and artificial intelligence technology to quickly detect signs of corrosion, cracks, leakage, or thermal problems.
Oil and gas corporations make use of autonomous drones in performing flare stack inspections and pipeline inspections. While a routine inspection done manually can take a few days of downtime, an inspection performed by drones can be achieved in a matter of hours. Drone technology also minimizes hazardous tasks on the part of employees.
Pipe and Pipeline Crawling Robots
Pipeline crawling robots are used to inspect pipelines, sewage systems, water systems, and refinery systems from inside. Such robots move through small pipes with tracks, wheels, or serpentine movement, collecting structural data within using cameras and sensors for non-destructive testing.
Crawler robots are most useful when inspecting pipelines that cannot be inspected by other means and are thus referred to as “unpiggable.” Crawler robots used in oil and gas production help identify pipeline corrosion, weld problems, cracks, and sediments without digging up or disassembling the entire system. Some newer crawler robots are capable of navigating through complicated pipe shapes on their own via reinforcement learning techniques.
Underwater and Subsea Inspection Robots
Underwater inspection robots, such as ROVs and AUVs, are extensively employed in offshore oil platforms, underwater pipelines, and marine structure inspections. Underwater robots perform their functions at great depths where it is dangerous for human divers to work.
Submersible robots have roles such as structure testing, leakages underwater, ocean bottom scanning, and corrosion checking. The offshore industry makes use of AUVs because of their capability to be submersed for prolonged periods, providing clear images through the use of sonar. Research articles indicate that there is a growing trend of use of autonomous underwater robots by the offshore industry.

Robotic Arms for Precision Inspection
Robotic arms inspection machines are usually used in the aerospace industry, the semiconductor industry, and heavy machinery manufacturing due to their need for precision. Robotic arms employ the use of machine vision, tactile sensors, and lasers to check the quality of welding, the presence of surface flaws, and dimensional precision.
Latest advancements in robotic inspections have allowed the detection of micrometer-level defects on aircraft parts and metallic surfaces. In recent studies, it was found that multi-mode robotic inspection systems had an 85% success rate in visual inspection and 100% in tactile examination.
