Blueberry Harvester Optimization

ZEISS Corona Process Vis/NIR Spectrometer + Custom Mount on Oxbo 7450 Blueberry Harvester

Objective 

Demonstrate real-time, inline detection of internal bruising in blueberries using a detection system mounted on an active Oxbo 7450 blueberry harvester without disrupting harvest speed or flow. 

Challenge Accepted 

Design and engineer a compact stabilizing mount for the ZEISS Corona Process Vis/NIR Spectrometer and integrate a panel PC and cable routing for live operation on a rugged, moving harvester system. Project required deliverable within a short time-frame. The system needed to:
  • Withstand vibration and harsh conditions  
  • Avoid interfering with operator workflows 

Solution Delivered 

Sigma Design co-developed a system with Ag Optix. We designed a compact custom mount that stabilizes a ZEISS Corona Process Vis/NIR Spectrometer and integrates a panel PC plus cable routing for live operation. 

Result 

With the new stabilizing mount in place, data was collected successfully during harvest. During a system test running over four harvest nights, the system ran cleanly without disrupting workflow. This data will be used for bruise detection, determining the ripeness of the berries, and maintaining high-quality standards for berry harvesting.

“We came to Sigma Design with a unique challenge: integrate a sensitive ZEISS Corona spectrometer onto a moving conveyor onboard a working harvester. This equipment is used heavily, daily during harvest operations. The solution had to be rugged, safe, and installable without disrupting the pace of work or compromising operator safety. Sigma Design delivered exactly that. 

Their design-driven process produced a precision-fabricated mount system that not only secured the spectrometer and maintained alignment but also integrated a panel PC and full cable management all in a compact, field-ready form. It performed flawlessly under real harvest conditions. 

What impressed us most was how Sigma Design balanced technical performance with human-centered design. The system didn’t just protect the optics—it improved workflow. The world of agriculture is rapidly becoming high tech, and it’s really great that Sigma has a design/fab outpost in Pendleton that is affordable and super responsive.”
