In the system of mechanized process cultivation fruit crops, harvesting is an important final stage, which requires development new, convenient, including those that do not damage fruit, automated technical devices. As a result series experiments, operability developed picking device was confirmed, it gently captures and reliably holds it. The operating modes for fruits have been established. f...

This study designed a handheld vibrating coffee harvester to improve the mechanized harvesting of Coffea arabica L. The proposed device was used vibrate branches trees, and shedding fruit operation parameters vibrational were analyzed. Images captured using high-speed photography derive force equation that represents forced vibration fruit-stalk joint. In addition, vibrations berries theoretica...

Apples should be quickly and correctly detected from their surroundings for the apple harvesting robot. The basic color feature was extracted from FuJi apple tree images and analyzed by the statistical analysis method. Accordingly, a new apple detection method was proposed to position the centroid of picking apples. The color difference was used to segment apples from their surroundings. Then t...

The spatiochromatic properties of the red-green dimension of human colour vision appear to be optimized for picking fruit in leaves at about arms' reach. However, other evidence suggests that the task of spotting fruit from a distance might be more important. This discrepancy may arise because the task a system (e.g. human trichromacy) is best at is not necessarily the same task where the large...

Machine vision technology has dramatically improved the efficiency, speed, and quality of fruit-picking robots in complex environments. Target recognition for fruit is an integral part systems picking robots. The traditional digital image processing a method based on hand-designed features, which makes it difficult to achieve better as results dealing with changing orchard environment. Numerous...

Abstract. This paper describes recognition and cutting system of sweet peppers for picking robots in greenhouse horticulture. This picking robot has an image processing system with a positioning system for two cameras and cutting a device to follow the sweet pepper by visual feedback control. A prototype robot system is introduced. Experiments of the prototype robot prove the performance of the...

Mechanized harvesting of crops is very important in the field agricultural engineering, then brush a common way. The comb device divided into four types: tooth type, roller spring finger belt and rod type. picking rate breakage are indexes to evaluate effect devices. How improve reduce damage great significance popularization To rate, design teeth should conform growth characteristics crops. In...

This paper describes development and experiments of a picking robot for sweet peppers in greenhouse horticulture. This picking robot has an image processing system with a parallel stereovision, a camera positioning system to follow the sweet pepper by visual feedback control, and a cutting device. A prototype robot system has been made and is introduced. Experiments of the prototype prove that ...
