ILVO's Agricultural Engineering research area, in partnership with companies, has great experience in machine development and adjustment. This has resulted in interesting concepts, prototypes and realisations. Our thorough knowledge of the field conditions when developing and evaluating prototypes is clearly valued by companies in search of technological assistance. Specific prototypes are designed and built in our own work shop in consultation with the company's representative. We have a great deal of experience relating to the incorporation of robust camera and sensor systems in prototypes to be used in demanding field conditions. We also design harvest machines and sensors for very specific niche applications.
