Description

Wireless Remote-Controlled Multi-Purpose Robot Vehicle for Open Field and Greenhouse The present invention relates to a wirelessly controlled multi-purpose robot vehicle for use in both open fields and greenhouses. More specifically, the invention relates to a wirelessly controlled multi-purpose robot vehicle for use in both open fields and greenhouses that can perform various service tasks, such as pest control and loading, accurately and conveniently in both open fields and greenhouses. In particular, the invention relates to a vehicle capable of driving over water supply pipes inside a greenhouse via a separate auxiliary wheel detachably mounted on the wheel rotation axle of a main wheel, thereby enabling the performance of various service tasks more conveniently and stably. Currently, as labor shortages become severe in many open fields, the labor reality is a serious difficulty in recruiting workers not only domestically but also from abroad. Considering these circumstances, the introduction of various agricultural machinery is increasing to improve labor convenience in open fields, and farm owners are highly welcoming the emergence of new smart farming equipment in open fields as it allows for significant cost savings. Under these circumstances, while the demand for domestic agricultural products is increasing every year, the number of workers is rapidly decreasing. Consequently, management in many open-field farms is deteriorating due to an aging workforce and labor shortages, leading to accumulated deficits and the sale of farmland on the market. As a result, restructuring of open-field farms is proceeding rapidly, and farm owners nationwide are making strenuous efforts to increase production. Above all, while the primary goal is to reduce costs for farm owners, the reality is that price competition—such as the reduction of labor hiring costs—is not a fundamental solution, leading to deep concerns. In this context, an operational method utilizing smart agricultural machinery, which takes into account the difficulty of recruiting labor, is being welcomed by farm owners. However, since the operation of smart machinery requires the farm owner to operate it directly, there are concerns about safety accidents during use. Furthermore, unlike in other countries, open fields in Korea have steep slopes, which entails significant difficulties in terms of safety and operation, making the active application of this technology a sensitive issue. Considering these circumstances, the most reasonable open-field management method to satisfy farm owners requires the distribution and operation of smart agricultural equipment, as well as the utilization of safe, convenient, and economical smart agricultural machinery. Conventional agricultural machinery consists entirely of the ability for an operator to drive or stop by directly operating the steering wheel, accelerator, and brakes after boarding, along with additional functions for logistics transportation. The reality is that the difficulty of moving agricultural machinery to the appropriate location is actually hindering farming operations, as it requires significant time and physical strength depending on the location of the open field and causes many accidents due to inexperienced driving or operational difficulties. To address these issues, research and development of wirelessly controlled robotic vehicles capable of providing various services is required. In particular, there is an urgent need for wirelessly controlled robotic vehicles that can reliably provide diverse services in both open-field and greenhouse environments, which differ significantly.
