How Explosion-Proof Robots Are Moving Beyond Traditional Applications

When most manufacturers think of explosion-proof robots, paint automation is often the first—and sometimes only—application that comes to mind. While FANUC’s explosion-proof robots have long been trusted for high-quality, consistent coating processes, their capabilities extend well beyond paint. Today, manufacturers across industries are recognizing the value of leveraging these robust, safety-certified systems in a wide range of hazardous and potentially volatile environments.

Why Explosion-Proof Robotics Matters

Explosion-proof (ex-proof) robots are purpose-built to operate in environments where flammable gases, vapors, dust, or particulates may be present. These systems are engineered to prevent ignition sources—such as sparks or excessive heat—from causing dangerous events.

Industries that commonly require ex-proof solutions include:

• Liquid and powder painting
• Chemical processing and handling
• Oil and gas
• Aerospace and defense
• Ordinance and munitions
• Combustible Powder and bulk material handling

Historically, automation in these environments has been limited by stringent safety requirements. FANUC’s explosion-proof cobot address this gap, enabling safe, reliable automation where it was previously difficult or cost-prohibitive.

Moving Beyond Paint Applications

While designed for painting, coating, and related processes—including powder, gel, and fiberglass-reinforced applications—the FANUC paint product line-up is already proven across a broad set of industrial uses.

The FANUC paint robot product line offers payloads ranging from 5kg to 45kg and are widely used for: pick and place, palletizing, machine tending and welding. This versatility reinforces the opportunity to extend explosion-proof cobots into new applications, bridging the gap between traditional paint automation and broader industrial use cases.

Some of the applications that explosion-proof robots, including our new FANUC’s CRX-10iA/L paint cobot, can successfully automate include: 

Machine Tending and Lathe Operations

Explosion-proof robots are increasingly being deployed for machine tending in hazardous environments, including CNC and lathe operations where flammable coolants or fine particulates may be present.

Benefits include:

• Reduced operator exposure to hazardous environments
• Improved cycle time consistency
• Enhanced uptime with continuous automation

The flexibility of FANUC robots allows them to integrate seamlessly with existing machining systems while maintaining safety compliance.

Bag Handling and Bulk Material Processing

In industries dealing with powders or granular materials—such as chemicals, food ingredients, or specialty materials—dust accumulation can create explosive atmospheres.

Ex-proof robots are ideal for:

• Bag palletizing and depalletizing
• Material transfer in dust-prone zones
• Packaging automation

By automating these repetitive tasks, manufacturers can reduce ergonomic risks while improving throughput and maintaining strict safety standards.

General Hazardous Material Handling

Beyond specific verticals, many manufacturing facilities require ex-proof solutions for general material handling in classified areas.

Typical applications include:

• Loading/unloading hazardous materials
• Handling containers in flammable environments
• Supporting inspection and secondary processes

These systems enable manufacturers to extend automation into areas previously reliant on manual labor due to safety constraints.

The Role of the CRX-10iA/L Explosion-Proof Cobot

One of the most significant advancements in this space is the FANUC CRX-10iA/L explosion-proof collaborative robot (cobot). As the first explosion-proof collaborative robot certified for global use, it brings a new level of flexibility and accessibility to hazardous environments. 

Key Advantages

• Collaborative operation: Designed to work safely alongside human operators
• Ease of deployment: Intuitive drag-and-drop programming and lead-through teaching simplify setup—even for users with little or no robotics experience 
• Compact footprint: Lightweight design with a small installation footprint for flexible deployment
• Versatility: Easily redeployed across multiple applications beyond paint
• Global compliance: Designed to meet stringent explosion-proof standards worldwide (including IECEx and ATEX) 

With a 10 kg payload and extended reach of over 1.4 meters, the CRX-10iA/L can access large or hard-to-reach work areas, helping automate tasks that may be ergonomically challenging or unsafe for human workers. 

Like other CRX models, it also offers maintenance-free operation for up to eight years, supporting lower total cost of ownership and long-term reliability.

Unlocking New Opportunities in Hazardous Environments

As manufacturers continue to prioritize safety, productivity, and workforce optimization, explosion-proof robotics is becoming a strategic investment rather than a niche solution.

By moving beyond traditional paint applications, ex-proof robots are enabling:

• Safer working environments
• Increased automation in previously inaccessible areas
• Greater operational efficiency and consistency
• Flexible deployment across multiple processes
• Faster adoption, even for first-time robot users

The evolution of explosion-proof robotics is transforming how manufacturers approach automation in hazardous environments. What began as a solution for paint applications is now a versatile platform supporting a wide range of industrial processes.

By combining global safety compliance, ease of use, and proven versatility, FANUC’s explosion-proof robots empower manufacturers to rethink what’s possible—extending automation well beyond the paint booth and into the broader factory floor.
