Integrating robotics into hygiene-sensitive industries such as food processing, medical or pharmaceutical sectors requires strict adherence to high standards such as GMP and ISO Cleanroom Class. Yaskawa's groundbreaking Motoman HD7 and HD8 robots, launched in the spring of 2024, address these challenges with innovative designs that prioritise cleanliness and compliance.
Key Features and Development
Both the HD7 and HD8 robots feature a screwless design, gapless rotary joints and hygienically designed user ports. These advances are the result of extensive research and development, including a thorough analysis of the existing GP7 and GP8 robots. Key improvements include the elimination of external screws, smooth transition surfaces to prevent dirt accumulation, and the use of proven materials to improve cleanability and durability.
A major challenge was sealing the gaps at the robot joints, which is critical to maintaining hygiene standards. To overcome this, Yaskawa engineers developed custom axial seals to ensure IP69K compliance and minimal particle generation. The seal geometry and material composition were defined to achieve the optimum balance between hygienic design and functional performance.
Validation and Achievements
Both robots have undergone extensive validation tests, including high-pressure washdowns, chemical resistance tests and cleanability assessments, carried out in close collaboration with the Fraunhofer IPA Institute in Germany. They are suitable for use in GMP Class A areas and ISO Class 5 (HD7) and ISO Class 4 (HD8) cleanrooms.
The Motoman HD7 has also been awarded the Red Dot Design Award 2024 for its special design.
