Cognitive Robots for Flexible Agro Food Technology (Flexcraft)

Robots that automatically harvest tomatoes or package biscuits in boxes of various sizes are now becoming a reality: Wageningen University & Research will be working together with various partners to develop flexible robotics for food production as part of the new and comprehensive FlexCRAFT research programme. Within the Perspectief Programme framework, the board of the Domain Applied and Engineering Sciences of the The Netherlands Organisation for Scientific Research (NWO) has made 2.7 million euros available for this research to which another 1.3 million euros has been added by the corporate sector.

‘Food production has to be as hygienic, efficient and sustainable as possible,’ explains head of the programme Eldert van Henten. ‘Moreover, fewer people are willing to do boring and heavy work in warm, humid greenhouses or cooled processing facilities in which products such as chicken are processed. Robots can provide a solution, as they never tire and function well at low temperatures. However, they do need to be able to handle the substantial variation in shape, size and hardness of different food products. That is still difficult to realise at present.’

New technology for robotics

The FlexCRAFT programme is developing new robotics for the automated harvesting of tomatoes, the processing and packaging of chicken products and the packaging of bags of crisps and boxes of biscuits into boxes of different sizes. ‘We are developing generic skills for robots which enables them to perform operations on agri-food products that differ in shape, size and hardness. One of these skills is actively detecting objects in complex environments in which the target object is partially hidden. These are things such as the peduncles of  fruits which are not always visible.’ The sensors collect information which is recorded in a world model together with all known domain knowledge in a similar way that people gather and remember knowledge and experience.
