Sonar Sensor Based Intra Row Weeding Prototype for Row Crops
Intra-row weeding is also challenging due to weeds aligned with main crops. Pertinent to these circumstances, an ultrasonic sensor-based precision weeding system was developed. This system integrates sensor with lateral shifting mechanism (LSM) through a …
Oct 24, 2019 · sensor based weeding technology was developed that removes weeds in the intra-row zone in addition to protecting the main crop by sensing their physiology. A controller algorithm was developed to direct the electro-mechanical units for efficient operation.
Ultrasonic sensors differentiate between crops and weeds based on their height, allowing precise weed removal without damaging crops. The weeder significantly reduces manual labor, covers large areas quickly, and integrates easily with existing farm machinery.
The intra row weeds were detected by ultrasonic sensors, which transferred signal to the controller. Controller guided the pump cum motor based on received signal whether the obstacle was a weed, a crop plant or a soil clod.
A study was conducted to assess the use of ultrasonic sensors to detect weeds in the inter- rows of maize, exploring their capabilities and limitations to discriminate weed species of different heights.
The weeder operation was based on rollers mechanism to uproot intra-row weeds and ultrasonic distance sensor to discriminate between crop/weed plants. The operation of the weeder...
Performance and Evaluation of Intra-Row Weeder Ultrasonic …
A real-time plant detection system based on ultrasonic sensing system was used to detect the location of crop plants and control the operation of the weeding mechanism between crop plants along the centerline of the crop row.

Jul 3, 2018 · The operations of FBL mechanism also ensure no weed clogging or risk of plant damage. Therefore, an ultrasonic sensor has been used in this invention, which senses the height of desired plants (crops) and removes remaining weeds.
An Automated Mechanical Weed Control System for Organic Row …
The goal of this study was to develop a mechanical intra-row weed control prototype. The prototype uses rollers mechanism to uproot intra-row weeds, and ultrasonic distance sensor to discriminate between crop/weed plants.
Sensor-based mechanical weed control: Present state and prospects
Sep 1, 2020 · With an ultrasonic sensor mounted in front of the tractor, online weed detection was realized, and real-time adjustment of the harrow tines was performed. It was assumed that areas with high plant densities have a high degree of weeds inside, thus requiring aggressive treatment with …
