The adoption of robotics in pack houses for fresh produce handling

Fresh produce handling, particularly in final inspection and pack, is highly dependent on dextrous human labour. As part of a relatively low-profit margin industry, rising wage costs and labour shortages are impacting the viability of this sector and are a direct threat to global food security. Adoption of robotics is required to automate delicate handling tasks; this is a key goal for sustainable and profitable businesses that supply packed produce to consumers. This mini review considers the state of the art, as well as any developments required in robotic technology for the automation of inspection and packing of whole unprocessed fresh produce. There is a particular focus on robotic end effectors for the handling of fresh produce. We consider the role of soft robotics research in meeting hygiene and safety requirements, as well as the current limited range of end effectors for handling of highly varied and delicate produce types. Future directions are discussed based on the observation of available current technology available in research and the application to commercial practice.
