Precision farming is the newest agricultural approach in countries with highly mechanized field operations, and role of unmanned ground vehicles (UGVs) smart becoming increasingly prominent. This work aimed to evaluate stability DEDALO UGV developed by University BOLOGNA for precision orchard vineyard management. The driving part machine somewhat peculiar; it moves autonomously combined a tank ...

An image processing-based variable rate chemical sprayer for disease and pest-infested coconut plantations was designed and evaluated. The manual application of chemicals is considered risky and hazardous to workers, and provides low precision. The designed sprayer consisted of a sprayer frame, motors, a power system, a chemical tank and pump, a crane, a nozzle with a remote monitoring system, ...

Farmers experience whole-body vibrations when they drive tractors. Among the various factors that influence the vibrations to which the driver is exposed are terrain roughness, tractor speed, tire type and pressure, rear axle width, and tractor seat height above the ground. In this paper the influence of tractor seat height above the ground on the lateral vibrations to which the tractor driver ...

Weed control automation appears to be a very promising technology based on the tremendous advances in computer processing, machine vision and robotics. Machine systems are size differences between crops weeds or regular structure of crop rows, allowing system recognize plants surrounding weeds. The paper provides description mounted for orienting row cultivator rows its displacement relative tr...

A field study was conducted to explore the suitability of 5 pesticide deposition samplers for airborne spray and ground deposits from ultra-low-volume (ULV) space sprays. Samplers included horizontally stretched stationary cotton ribbons at 2 heights, rotating ribbon, rotating Teflon slides, and filter paper. Slides were also used for droplet-size analysis. A set of 7 samplers of each type was ...

Autonomous modular system mounted on a conventional (CON) sprayer operating the principle of pulse-width modulation (PWM) control electromagnetic valves represents state-of-the-art technology for implementation controlled application spray mixture without changing parameters (e.g. pressure, nozzle size). In accordance with principles precision viticulture, pulse width is primary technology, whi...

We conducted an open-field ultra-low volume efficacy bioassay using a water-based formulation AquaDuet (prallethrin [1%], sumithrin [5%], and piperonly butoxide [5%]) applied from a truck-mounted cold aerosol sprayer. The adulticide was applied at 90.6 ml/ha (1.23 oz/acre) and 3 replicated treatments were performed using caged Aedes albopictus collected from local wild populations. Rotating imp...

This paper discusses the derivation of the best related linear dynamic system approximation to a tractorsprayer combination and a parametric model for the related linear dynamic system is identified. It will be of interest to check the degree of non-linearity in order to consider the validity of linear dynamic models. A simple method has been utilised based on the kernel idea of well-chosen per...

An experimental machine vision-based patch-sprayer was developed. This sprayer was primarily designed to do real-time weed density estimation and variable herbicide application rate control. However, the sprayer also had the capability to do high-resolution weed mapping if proper mapping techniques being integrated. Two weed mapping methods were developed. One is GPS signal-based off-line weed ...
