Automatic Weed Killing Robot for Agriculture Purpose and Insect Killing

摘要

Comprehensive review of autonomous robotic weed control systems, reported that systems for plant detection and their classification (crop vs. weed) conferred the best technical challenge for development of a victorious weeding mechanism. Methods for precision weed control also needed further development. Although the few fully autonomous robotic weeding systems that had been developed at the time showed promise for reducing hand labor and/or pesticide requirements, none had been successfully commercialized. Since then, technology has advanced and a number of other machine-driven weeding machines area unit commercially offered. This paper describes some of these devices and provides an update on the current state of robotic weeding. Commercial robotic weeding machines utilize one of several means to kill weeds including mechanical, flame or herbicidal spray. Classifying plants as either crop or weeds is difficult with system accuracy of around only 70%, even under ideal conditions. There are many ways to identify crop plants in digital images, but typically this is done by first analyzing a captured imaged and classifying each pixel in the image as being either a plant or a non-plant part using some type of green threshold technique. Herbicides are used worldwide to manage agricultural weeds. Over 95% of herbicides reach a destination other than their target crops, because they are sprayed or spread everywhere in the agricultural fields. This causes many unwanted effects on environment, humans and other living organisms. The automatic weed control systems provide efficient method of weed removing within the rows and inter rows. The machine vision system has been used to detect and differentiate the weeds from the crop. Guidance system has been used to track the rows with accuracy and to control a row cultivator and an autonomous agricultural robot in real-time. Mechanical methods of automatically removing weeds from the sideline two basic designs are used: a mechanical knife removes weeds from the inter rows and rotating hoe are used to remove the weeds from the within rows. The proposed system is helpful to avoid the usage of herbicides in the agriculture field and also replaces the shortage of labor.
