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...

Fruit location is an important parameter for apple harvesting robot to conduct picking task. However, it is difficult to obtain coordinates of each apple under natural conditions. One of the major challenges is detecting adjacent fruits accurately. Previous studies for adjacent detection have shortcomings such as vast computation, difficulty in implementation and over-segmentation. In this pape...

Automated fruit-picking equipment has the potential to significantly enhance efficiency of picking. Accurate detection and localization fruits are particularly crucial in this regard. However, current methods rely on expensive tools such as depth cameras LiDAR. This study proposes a low-cost method based monocular images achieve target estimation. To improve accuracy targets, especially small a...

Quality characteristics of tomato fruit will be affected by a number preand post harvest factors. In this study, the effect of maturity stage on post harvest quality characteristics of tomato was investigated. Tomato fruits of the same farmers‟ variety were harvested at mature-green, medium ripe and full-ripe stages. After harvesting, tomato samples were sliced and homogenized in blender for pr...

When designing objects, designers attempt to communicate the purpose and meaning of that object users using various factors such as visual appearance (aesthetic), practical interaction elements (product semantics) meanings beyond product (semiotics). This study sought confirm previous deductively-developed soma-semiotic framework, whose was understand ultimately predict emotional impact differe...

In order to improve robotic harvesting and reduce production cost, a harvesting robot system for strawberry on the elevated-trough culture was designed. It was supposed to serve for sightseeing agriculture and technological education. Based on the sonar-camera sensor, an autonomous navigation system of the harvesting robot was built to move along the trough lines independently. The mature fruit...

Pymatuning Lake, located on the Pennsylvania/Ohio border, is noted for the large numbers of bread-eating carp that frequent the Linesville Causeway "carp bowl" from May to November. Carp were trapped in 1952 and 1984 at the carp bowl, tagged, and relocated varying distances away from the bowl in Sanctuary, Middle, and Lower lakes. Carp traversed the return distances of up to 9 km in less than 4...

Objective: The use of smaller dishware as a way of reducing food consumption has intuitive appeal and is recommended to the general public. Recent experimental studies have failed to find an effect of plate size on food intake, although the methods used across studies have varied. The aim of the present study was to examine the effect that bowl size had on snack food consumption in a ‘typical’ ...

In Drosophila, antennae and legs are serially homologous appendages, and yet they develop into organs of very different structure and function. This implies that different genetic mechanisms operate onto a common developmental ground state to produce antennae and legs. Still few such mechanisms have been uncovered. During leg development, bowl, a member of the odd-skipped gene family, has been ...
