Abstract In this study, we propose a method to automate fruit harvesting with robot equipped robotic arms. Given the future growth of world population, food shortages are expected accelerate. Since much Japan’s agriculture is dependent on imports, it be greatly affected by upcoming shortage. recent years, number agricultural workers in Japan has been decreasing and population aging. As result, ...

harvesting of sour cherries is very difficult task which is done either by machine or hand. in order to facilitate fruits harvesting ethephone with different densities is used. in this research work iranian produced ethephone with density of 1.18 g/cm3 and england produced ethephone with density of 1.45 g/cm3 was utilized with different concentration (0, 150, 225 and 300) in a 2×4 factorial exp...

Storage at 3 and 18 °C of 'Arbequina' olives (Olea europaea L.) cultivated in hedgerows and harvested manually or mechanically (wine grape harvester) was tested. Fruit characteristics and oil quality were monitored. Mechanical harvesting caused internal fruit damage that induced its rapid softening and decay, but also facilitated obtaining higher amounts of oil, which suffered a rapid deteriora...

Automation in cherry harvesting is essential to reduce the demand for seasonal labor for cherry picking and reduce the cost of production. The mechanical shaking of tree branches is one of the widely studied and used techniques for harvesting small tree fruit crops like cherries. To automate the branch shaking operation, different methods of detecting branches and cherries in full foliage canop...

In the EU-funded CROPS (Clever Robots for Crops) project high tech robots are developed for site-specific spraying and selective harvesting of fruit and fruit vegetables. The harvesting robots are being designed to harvest high-value crops such as greenhouse vegetables, fruits in orchards and grapes for premium wines. The CROPS robots are also developed for canopy spraying in orchards and for p...

 Rosemary (Rosmarinus officinalis L.) is an important medicinal plant that contained a wide range of secondary metabolites such as rosmarinic acid. In this study, essential oil content and composition and rosmarinc acid were determined at three phenological stages (before flowering, full flowering and fruit set stages). Hydro distillation method was used for essential oil extraction and GC and ...

We determined if winter drought stress could delay flowering and fruit development of immature ‘Valencia’ sweet oranges to avoid young fruit loss during late-season mechanical harvesting. Beginning in December over three consecutive seasons (2007–2009), Tyvek water-resistive barrier material was used as a rain shield groundcover under 13to 15-year-old trees. There were three treatments: 1) drou...

In order to clarify the influence of the rootstock cultivar and fruit storage on the texture of cucumber (Cucumis sativus L.) fruit, we examined the physical properties of the fruit, i.e., flesh firmness, placental firmness, skin toughness, and the crispness index. Cucumber fruits from own-rooted plants and from plants grafted onto the three rootstock cultivars of ‘Shin-tosa’ (Cucurbita maxima ...

This work proposes the development of an embedded real-time fruit detection system for future automatic fruit harvesting. The proposed embedded system is based on an ARM Cortex-M4 (STM32F407VGT6) processor and an Omnivision OV7670 color camera. The future goal of this embedded vision system will be to control a robotized arm to automatically select and pick some fruit directly from the tree. Th...

The aim of this study was to determine the most suitable shaking frequency and amplitude for shake harvesting lime fruit (C. aurantifolia). A tractor mounted limb shaker with adjustable shaking frequency and amplitude, powered by the tractor power-take-off shaft was designed and developed for this study. The rotating input power was transmitted to the shaker flywheel through a multiple sheave v...
