Abstract In the EU-funded CROPS project robots are developed for site-specific spraying and selective harvesting of fruit
and fruit vegetables. The robots are being designed to harvest crops, such as greenhouse vegetables, apples,
grapes and for canopy spraying in orchards and for precision target spraying in grape vines. Attention is paid
to the detection of obstacles for autonomous navigation in a safe way in plantations and forests. For the different
applications, platforms were built. Sensing systems and vision algorithms have been developed. For software
the Robot Operating System is used. A 9 degrees of freedom manipulator was designed and tested for sweetpepper
harvesting, apple harvesting and in close range spraying. For the applications different end-effectors
were designed and tested. For sweet pepper a platform that can move in between the crop rows on the
common greenhouse rail system which also serves as heating pipes was built. The apple harvesting platform
is based on a current mechanical grape harvester. In discussion with growers so-called ‘walls of fruit trees’
have been designed which bring robots closer to the practice. A canopy-optimised sprayer has been designed
as a trailed sprayer with a centrifugal blower. All the applications have been tested under practical conditions.
