Mobile machinery and remote operation:
Why carry out remote operations in hazardous areas?

In many industrial and operational sectors, direct human intervention is not always possible — or desirable. Exposure to toxic substances, explosion risks, structural instability or extreme environmental conditions: certain situations make human presence too risky. It is in these situations that remotely operated mobile vehicles come into their own.

 

What is a remotely operated vehicle?

A remotely operated vehicle is a mobile craft (land, air or sea) controlled remotely by a human operator, usually via a digital interface. Unlike fully autonomous systems, remote operation retains real-time human decision-making, whilst keeping the operator away from danger.
These systems generally combine:

• sensors (cameras, LIDAR, radar)
• communication systems (radio, 4G/5G, satellite with a latency of 65ms)
• and ergonomic control interfaces

Why use remote operation in hazardous areas?

Protecting human life

The main reason is obvious: to avoid exposing operators to hazardous environments. Whether it is a fire, a chemical spill or a contaminated area, remote operation makes it possible to intervene without putting human lives at risk.

Working in inaccessible environments

Some areas are physically difficult to access: collapsed tunnels, the seabed, contaminated areas, or unstable terrain. Remotely operated vehicles can navigate these areas more easily, often thanks to their specialised design (caterpillar tracks, drones, underwater robots).

Maintaining operational capability in extreme conditions

Extreme temperatures, high pressure, toxic atmospheres… these are all conditions in which humans cannot survive for long. Machines, on the other hand, can be designed to withstand these conditions.

 

The main areas of use

 

Hazardous industrial environments

In certain factories (chemical, metallurgical), remotely operated vehicles are used in:

• areas of extreme heat,
• toxic environments,
• confined spaces.

Oil and gas sector

At sea, particularly on offshore platforms, remotely operated vehicles are used to:

• inspect infrastructure,
• carry out repairs,
• monitor pipelines.

Defence and mine clearance

The armed forces make extensive use of remote-controlled operations to:

• defuse explosives,
• monitor hostile areas,
• carry out reconnaissance missions.

This significantly reduces casualties.

 

Nuclear industry

In nuclear power stations or during incidents, for:

• inspecting facilities,
• carrying out maintenance work,
• responding to accidents.

Civil protection and emergency response

Remote-controlled robots are used by rescue teams to:

• search collapsed buildings,
• locate victims,
• handle dangerous objects (e.g. explosives).

They enable rapid action whilst minimising the risks to rescue teams.

 

 

The benefits of remote operation

 

Safety
The operator is kept away from the hazard zone, which drastically reduces the risk of accidents involving people.

Precision and human control
Unlike fully autonomous systems, teleoperation allows for real-time human decision-making, which is essential in complex and unpredictable situations.

Operational flexibility
The same machine can be used in different contexts with software or hardware adaptations.

Long-term cost savings
Fewer accidents, less high-risk training, less heavy protective equipment: the indirect savings are significant.

Real-time data collection
On-board sensors transmit valuable information for decision-making (images, temperatures, chemical measurements, etc.).
Technological advances (5G, artificial intelligence, immersive interfaces) are, however, helping to reduce these constraints. At efa, we offer a bespoke telematics solution.

Remotely operated mobile vehicles have become indispensable tools for carrying out operations in hazardous areas. They enable a balance to be struck between operational efficiency and the protection of human life, whilst paving the way for new operational capabilities.

As technologies evolve, the line between remote operation and autonomy is becoming increasingly blurred, promising systems that are ever more capable, safe and intelligent.

Remote operation, or telemanipulation, consists of controlling machines remotely using interfaces such as screens or specific controls. This technology is developing rapidly in a variety of sectors, including industry, logistics, public works and the environment, offering numerous advantages in terms of safety, productivity and efficiency:

Enhanced safety: One of the major benefits of teleoperation is improved operator safety. In hazardous environments such as toxic zones, sites at risk of explosion or contaminated sites, operators are far from sources of danger, reducing the risk of accidents. What’s more, it enables work to be carried out in inaccessible areas, such as underwater sites, radioactive zones or extreme environments.

Improved productivity: By enabling machines to operate continuously without human physical constraints, teleoperation speeds up operations. It eliminates the downtime associated with difficult working conditions for operators, resulting in increased productivity.

Cost optimisation: Teleoperation also reduces the costs associated with worker health and safety. Fewer staff are exposed to risks, which reduces the cost of protective equipment and training. In addition, operator travel is reduced, cutting transport costs.

Operational flexibility: With teleoperation, an operator can manage several sites remotely from a single control station, offering unprecedented flexibility. In the event of an emergency, machines can be quickly activated without a team having to travel to the site.

Greater precision: Thanks to on-board technologies such as sensors and decision-support tools, remotely-operated machines can carry out operations with great precision, whether in logistics for sorting or handling heavy loads, or in public works for tasks such as earthmoving.

Reduced Environmental Impact: By reducing the number of journeys required of operators, teleoperation helps to reduce CO₂ emissions. In environmental terms, it enables work to be carried out in sensitive areas while minimising human disturbance.

Technological Development and Innovation: Teleoperation paves the way for robotisation and the complete automation of processes. It is fully integrated into Industry 4.0, where connectivity and advanced technologies, such as augmented reality and artificial intelligence, play a key role in innovation.
