Development of Picking Robot in Greenhouse Horticulture

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 ...

Sweet Pepper Picking Robot in Greenhouse Horticulture

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...

Effect of Inaccurate Measurements on Energy Consumption in Greenhouse Horticulture

The influence of inaccurate sensors, used in practice in greenhouse climate control, on the energy consumption of greenhouse horticultural production is investigated. It is shown that the inaccuracy of sensors, caused for instance by improper maintenance, leads to a higher energy use. Copyright © 2008 IFAC

Characterization of Soil Suppressiveness to Root-Knot Nematodes in Organic Horticulture in Plastic Greenhouse

The fluctuation of Meloidogyne population density and the percentage of fungal egg parasitism were determined from July 2011 to July 2013 in two commercial organic vegetable production sites (M10.23 and M10.55) in plastic greenhouses, located in northeastern Spain, in order to know the level of soil suppressiveness. Fungal parasites were identified by molecular methods. In parallel, pot tests c...
