Application example

Automated Gripping of Baked Goods on a Conveyor Belt

The Task

In an industrial bakery, rolls, pancakes, donuts, and bagels are produced on an automated production line. After coming out of the oven, these baked goods must be removed from the conveyor belt and placed in boxes by a robot. At the same time, the degree of browning of each item must be assessed to ensure quality.

The Challenge

Baked goods vary in size, shape, color, and degree of browning, making reliable detection and handling a complex task.

Our Solution

The VISOR®Robotic Color provides the tools needed to solve the application.
By configuring the color channel, the sensor can binarize the image, turning all pixels within a defined color range black and highlighting any deviations in white.
The BLOB detector reliably locates each baked good for precise handling.
Thanks to its compact and robust design, the vision sensor can be integrated directly into the robot gripper.
Standardized calibration plates convert image coordinates into world coordinates, while matching light strips ensure uniform illumination.
With the high computing power of the VISOR®, position coordinates are available just milliseconds after image capture, enabling fast and accurate gripping of baked goods.

Your Advantages

  • Powerful color channel features for binarization
  • BLOB detector with proven functions including a free-form tool and geometric evaluation
  • Fully automatable hand-eye calibration delivers real X/Y and angle data without complex calculations on the robot controller
  • Compact, high-performance VISOR® hardware ideal for direct mounting on robot grippers
  • Reduced cabling effort with robot-compatible, AIDA-compliant push-pull cables
  • VISOR® software functions for precise component position determination
  • Easy integration with leading robotics systems, including:
    • Automated calibration to the robot coordinate system
    • Automated validation of position data
    • Standardized coordinate transmission
