Robotic Food Applications Example: Ice Cream Portioning

Abstract

This paper presents the research findings and describes the commercial application of a development in robotic food processing: ice cream portioning. The challenges for robotics in handling and processing of food items are the high degree of product variability, the fragile and perishable characteristics and the hygiene and sterilisation requirements. Information on item variability is acquired employing smart sensing combined with a priori knowledge. This product information is then processed by adapting the generic operation instructions and by correcting any deviations using feedback information from the process. Fundamental issues in robotic food processing are discussed briefly, followed by specific issues on portioning of ice cream for vending purposes. Implementation details and test results are presented with an attempt to critically review the lessons learned. An international patent has been approved and commercial developments are progressing in New Zealand with sales in Europe.
