Method for the influence design assessment of a wheeled agricultural vehicle on the soil

The impact of a wheeled agricultural vehicle on the deformable support surface determines the vehicle's ability to move, as well as soil compaction, which is not desirable in agriculture. The agricultural machine must not cause more pressure on the ground than is permissible. Therefore, in the tasks of design numerical modelling of the agricultural vehicle movement or trailer, it is required to calculate the specified parameter. It is impossible to calculate without knowledge of the geometric characteristics of the contact spot associated with the normal deformation of the tire under normal load. To calculate these characteristics, it is necessary to have universal dependencies for determining the normal stiffness of the tire. These are available for tires of various purposes. The elastic properties of ultra-low pressure tires are insufficiently studied. Experimental studies of the elastic properties of these tires have been carried out with the authors participation. However, there are currently no dependencies to describe them. This does not provide the possibility of a correct design calculation of the influence of such tires on the soil. The purpose of the work: to develop a universal method for calculating the influence on the soil of agricultural vehicle. A universal method for calculating the impact of a wheeled agricultural machine on the ground has been developed. Universal design-experimental dependence for determining the normal stiffness of ultra-low pressure tires is obtained. It takes into account tire pressure, normal load under specific conditions and geometric characteristics.

Performance Evaluation of an Autonomously Driven Agricultural Vehicle in an Orchard Environment

To address the problems of inefficient agricultural production and labor shortages, there has been active research to develop autonomously driven agricultural machines, using advanced sensors and ICT technology. Autonomously driven speed sprayers can also reduce accidents such as the pesticide poisoning of farmers, and vehicle overturn that frequently occur during spraying work in orchards. To develop a commercial, autonomously driven speed sprayer, we developed a prototype of an autonomously driven agricultural vehicle, and conducted performance evaluations in an orchard environment. A prototype of the agricultural vehicle was created using a rubber-tracked vehicle equipped with two AC motors. A prototype of the autonomous driving hardware consisted of a GNSS module, a motion sensor, an embedded board, and an LTE module, and it was made for less than $1000. Additional software, including a sensor fusion algorithm for positioning and a path-tracking algorithm for autonomous driving, were implemented. Then, the performance of the autonomous driving agricultural vehicle was evaluated based on two trajectories in an apple farm. The results of the field test determined the RMS, and the maximums of the path-following errors were 0.10 m, 0.34 m, respectively.

Exploration or Multipurpose Electric Vehicle for Agriculture Using IOT

Objectives: Objective: In this paper suggests a multipurpose portable type agricultural vehicle which can perform many functions of agriculture like seed sowing, water sprinkling and fertilizer spraying using a single agricultural vehicle. In the present scenario the agriculture is becoming of less interest even for the skilled people due to the increase in capital cost and decrease in the selling price. It is the time for introducing different machines with less human interference and also better with automated vehicles. There are different modern machines/tools that are accessible to farmers in order to perform various functions in agriculture. Each machine/tool can perform its own intended function. Methods: This agricultural vehicle is an automated vehicle where the control is based on IOT and can be controlled remotely. The proposed system involves PMDC motors as a driving mechanism and servomotor is used for controlling the output. The entire mechanism is controlled by NImyRIO embedded system. The programming of NImyRIO is developed using LabVIEW which is a visual programming language for easy user interface. Results & Conclusions: This exploration of multipurpose unmanned electric vehicle surely paves the ways to smart implementation scheme to the agriculture society including tobacco plantations.
