Televisual inspection (TVI) is a key process in industry, sewerage and underground networks: it enables the condition of infrastructures to be visually checked without direct human intervention - an imperative in confined environments. Traditional devices, such as wired ITV carts, are reliable in simple contexts. However, as networks evolve - labyrinths, flooded pipes, complex areas - these methods struggle to meet the demands for precision, speed and safety.
Multinnov now offers a radical alternative: the Roview2a wireless, lightweight, amphibious visual inspection robot with a 4K camera, real-time transmission and long autonomy. This article explores the advantages of the Roview2 over conventional ITV trucks, and the impact of these innovations on safety, maintenance and industrial efficiency - based on reliable information.
Reinventing television inspection
ITV forklifts: an old but limited standard
Wired ITV carts have long been the standard for visualizing the inside of pipes and ducts. Equipped with a camera, a light source and a rolling support, they can detect cracks, blockages or infiltrations, with live video feedback.
Advantages:
- Relatively simple installation in wide, straight or accessible ducts
- Direct visualization and control of infrastructure status
Limits:
- Limited range: generally limited to 50-150 m depending on cable length
- Tricky manoeuvres: bends or obstacles can trap the cable or cart
- Complex setup: requires deployment of cables, gondolas, logistics vehicles
- Compromised safety: work in sometimes dangerous areas (water, gas, containment) involving major human risks
These constraints reduce responsiveness, increase costs, and limit inspection coverage.
Roview2: innovation for precision
Introducing Multinnov's Roview2
The Roview2 is a compact robot (≈ 4 kg) designed to operate in confined, dry or flooded environments, without cables. Its technical features are impressive:
- Motorized 4K camera with 360° horizontal + 180° vertical rotation for complete visual coverage
- Powerful LED lighting (up to 12,000 lumens) for clear vision in the dark
- Operating time: 2 hours on, up to 8 hours off (LEDs off)
- Real-time wireless transmission, eliminating cable constraints
- Waterproof and buoyant, with amphibious capabilities thanks to wheel-mounted paddles
- Reinforced stability, resistance up to 45° tilt, 30° rollover warning
- Real-time telemetry and measurements, including distance travelled, ideal for ITV reports complying with NF EN 13508-2 standard
- Improved range: up to 500 meters in concrete networks, and up to 1-2 km in metal ducts (with range extender)
- Photogrammetry possible, using software such as Agisoft or Pix4D from recorded images
Quick comparison: Chariot ITV vs Roview2
| Criteria | Wired ITV cart | Roview2 (Multinnov) |
| Range | 50-150 m | 500 m to 1-2 km depending on network |
| Mobility | Limited by cable | Wireless freedom, capable of overcoming obstacles |
| Deployment | Slow, heavy logistics | Fast, transportable by a single operator |
|
Zone operation |
Single zones | Confined, aquatic, tortuous environments |
| Vision & quality | Basic, cable-dependent | 4K camera, powerful LEDs, panoramic view |
| Operator safety | Risks (confined, water, gas...) | Remote control, no human exposure |
| Autonomy | Limited by cable or battery | 2h continuous + extended options |
| Standards and measurements | Often without standards | NF EN 13508-2 compliant, integrated telemetry |
Impact on safety, maintenance and the future of inspections
Enhanced safety
The Roview2 streamlines interventions by avoiding human access to dangerous environments: floods, gas, confined spaces. Operators remain at a distance, analyzing from a safe position, without sacrificing precision.
Improved maintainability
Without cabling or heavy infrastructure, the robot can be deployed in just a few minutes from a light vehicle. Extended autonomy means that long areas can be covered in a single trip, with the possibility of accessing complex networks (dissuasive or winding).
Reduce costs and save time
Fewer mobilized personnel, more inspections per day, no draining required, fewer logistics - potentially up to 50-70% annual savings on inspection programs.
More complete and relevant inspection
4K camera, photogrammetry and telemetry provide comprehensive, usable diagnostics, improving maintenance planning.
A strategic French technology
Designed and manufactured by Multinnov in France, the Roview2 embodies innovation, technological sovereignty, local support and rapid maintenance. A major argument for public or industrial customers sensitive to the origin of their equipment.
Towards autonomous, intelligent inspection
Future versions could incorporate on-board AI for automatic anomaly detection, fault recognition, or accelerated 3D mapping - a future already mentioned by Multinnov.
The traditional ITV forklift has long served its purpose effectively. However, in the face of today's constraints - complex access, safety, efficiency - it is showing its limitations. The Roview2a wireless, floating, autonomous robot equipped with a 4K camera, represents a genuine revolution in television inspection in confined or submerged environments.
It combines :
- Maximum safety for operators
- Fast, flexible deployment
- Visual quality and usable data
- Lower operating costs
- Compliance with industry standards
At a time when industry demands reliability, performance and innovation - ideally with solutions made in France - the Roview2 from Multinnov stands out as a strategic choice for tomorrow's professionals.
