Yaskawa MOTOMAN-HD7 & HD8: Hygienic Robots for Pharmaceutical and Food Processing

In pharmaceutical production, laboratory automation and food processing, industrial robots must meet requirements beyond payload and positioning performance. Equipment surfaces, cleaning procedures, contamination control and environmental compatibility are also important.

Yaskawa's MOTOMAN-HD7 and HD8 are six-axis industrial robots developed for hygienic and cleanroom environments. The two models were included in Yaskawa's Japanese new-product announcement in June 2026, while the HD series had already been introduced in the European market.

With cleanroom compatibility, sealed construction and chemical-resistant surface treatment, the robots are designed for handling small containers and components in hygiene-sensitive production areas.

The HD7 offers a longer reach of 927 mm, making it suitable for workstations requiring a wider operating area.

The HD8 supports a slightly higher payload of 8 kg and is designed for ISO Class 4 cleanroom environments.

The choice between the two depends on the required payload, working distance and cleanroom classification.

A key feature of the MOTOMAN-HD series is its mechanical design for hygiene-sensitive environments.

Sealed robot structure

The robots use sealed axis designs and smooth exterior surfaces to reduce areas where dirt and contaminants can accumulate.

Chemical-resistant coating

Their special surface coating is designed to withstand specified cleaning agents, including hydrogen peroxide-based cleaning processes. Buyers should verify chemical compatibility against the manufacturer's approved cleaning instructions.

Food-grade lubricant

The robots use FDA-approved food-grade grease, supporting their use in environments where lubricant selection is an important hygiene consideration.

Hygienic construction

The design incorporates sealing and material features developed with reference to EHEDG recommendations.

These features can simplify cleaning and support equipment integration in controlled production environments.

The HD7 and HD8 are particularly relevant to applications where conventional industrial robots may not provide the required environmental compatibility.

Pharmaceutical manufacturing

Handling medicine containers, small packages and production components in controlled environments.

Laboratory automation

Transporting small vessels and laboratory items between automated workstations.

Life sciences

Supporting repetitive handling tasks involving chemicals and small containers.

Food processing

The hygienic design characteristics may also be relevant to selected food-handling operations. However, buyers should confirm the specific application requirements, material compliance and relevant hygiene approvals before installation.

Although both robots belong to the same hygienic series, they have different operating characteristics.

Choose the HD7 when:

• A longer working distance is required.

• The application needs a reach of up to 927 mm.

• The required cleanroom classification is ISO Class 5.

Choose the HD8 when:

• The application requires a cleanroom environment up to ISO Class 4.

• The required payload is within 8 kg.

• A shorter working range is sufficient.

In both cases, engineers should calculate the total load, including grippers and fixtures, and confirm the required working envelope.

For pharmaceutical and food-related automation projects, purchasing a hygienic robot requires more detailed checks than a conventional robot order.

Important considerations include:

1. Cleanroom requirements: Confirm the required ISO 14644-1 classification and whether the robot model meets it.

2. Cleaning chemicals: Check the approved cleaning agents, concentration and procedures.

3. Protection rating: Verify the specified IP protection and installation conditions.

4. Material compatibility: Review lubricant, coating and material requirements for the production environment.

5. System integration: Check grippers, cables, fixtures and surrounding equipment for compatibility with hygienic design requirements.

A hygienic robot alone does not make an entire production line compliant with pharmaceutical or food hygiene regulations. The complete system must be assessed.

The Yaskawa MOTOMAN-HD7 and HD8 are designed for automation tasks in cleanroom and hygiene-sensitive environments.

The HD7 provides a longer 927 mm reach, while the HD8 offers an 8 kg payload and ISO Class 4 cleanroom compatibility. Both models feature hygienic design elements intended to improve cleanability and support controlled production environments.

For pharmaceutical manufacturers, laboratory automation providers and selected food-processing operations, the HD series offers a specialized alternative to conventional industrial robots.
