The inspection of technical structures and industrial infrastructure is a major challenge for many industries. Sewer systems, nuclear facilities, industrial tanks, utility tunnels, and underground structures require regular inspections to ensure their proper functioning, compliance, and operational safety.
However, these operations are often carried out in complex environments that are difficult to access or classified as confined spaces. Given these constraints, traditional methods quickly reveal their limitations in terms of safety, cost, and efficiency.
At Multinnov, we develop inspection robot and indoor drone solutions designed to address these challenges. Using our visual inspection and ITV technologies, we help professionals collect reliable data while minimizing operators’ exposure to risks.
Multinnov: A French Specialist in Inspection Robotics
Since its founding, Multinnov has specialized in developing innovative solutions for exploring and inspecting hard-to-reach environments.
Our expertise is based on a simple observation: many critical infrastructures require regular inspections, but accessing them can pose a significant risk to field crews. Confined spaces, underground networks, and certain industrial facilities often impose significant operational constraints.
To address these challenges, we design and manufacture equipment specifically for remote visual inspection. These technologies provide accurate information on the condition of infrastructure while reducing the need for human intervention in the most sensitive areas.
Our solutions are designed for a wide range of industries:
- Sewage systems;
- Heavy industry;
- Energy;
- Nuclear;
- Technical infrastructure;
- Underground structures.
This approach helps enhance operational safety while improving the efficiency of inspection and maintenance campaigns.
Innovative Robots for CCTV Inspection
Innovation is at the heart of our approach. Our solutions are designed to meet the specific needs of professionals working in complex environments.
Roview3: The CCTV Inspection Robot for Pipelines
The Roview3 is our solution designed for the CCTV inspection of pipes and underground networks.
Equipped with an inspection camera, this inspection robot enables detailed visual inspections to be conducted inside structures without direct operator intervention. It facilitates the detection of numerous defects that could affect the performance of infrastructure:
- Cracks;
- Leaks;
- Obstructions;
- Structural damage;
- Connection defects.
Thanks to real-time image transmission, teams quickly have the information they need to make a reliable diagnosis and guide maintenance operations.
This approach improves the traceability of inspections while minimizing the need for extensive on-site work.
Stereo3: The Indoor Drone for Confined Spaces
Some infrastructure has access constraints that are incompatible with conventional methods or mobile systems. This is particularly true of large tanks, industrial chimneys, utility tunnels, and vertical structures.
To address these situations, we have developed the Stereo3, an indoor drone specifically designed to operate in confined spaces.
This technology enables rapid visual inspections in hard-to-reach areas while collecting actionable data for maintenance and engineering teams.
The Stereo3 is suitable for a wide range of applications:
- Inspection of tanks and reservoirs;
- Inspection of industrial chimneys;
- Exploration of underground structures;
- Inspection of nuclear sector infrastructure;
- Verification of complex technical structures.
The use of a drone significantly reduces the need for scaffolding, aerial work platforms, or work at heights, thereby saving a considerable amount of time.
The Outlook and Challenges of the Robotic Inspection Market
Changes in infrastructure and the aging of many networks are increasing the need for monitoring and preventive maintenance.
In this context, robotics and remote inspection technologies are playing an increasingly important role. Operators today are looking for solutions that can provide more data while reducing operational risks.
There are many observed benefits:
Enhanced safety
Reducing human intervention in hazardous areas is one of the main benefits of robotic solutions. Operators can conduct inspections remotely and limit their exposure to risks associated with confined spaces, heights, or potentially hazardous atmospheres.
Greater operational efficiency
Inspections conducted using an inspection robot or a drone generally reduce preparation and deployment times. Data is collected more quickly, facilitating decision-making and work planning.
Cost-effective optimization
Reducing the use of heavy equipment, minimizing operational downtime, and improving preventive maintenance all contribute to significant long-term cost savings.
Smarter Maintenance
Access to high-quality visual data improves the reliability of diagnostics. Operators can take targeted action before deterioration leads to a failure or a more costly service interruption.
Camera-based inspection has become an essential tool for ensuring the long-term viability of industrial infrastructure and technical networks. Thanks to innovative solutions such as the Roview3 and the Stereo3, we help professionals conduct safer, faster, and more accurate inspections.
By combining robotics, visual inspection technology, and on-site expertise, Multinnov is helping to transform the management of confined spaces and meet the growing demands for performance, safety, and efficiency in modern industry.
