Description

Outdoor Driving Mobile Robot System Capable of Exchangeable Battery The present invention relates to an off-road driving mobile robot capable of battery replacement, and more specifically, to an off-road driving mobile robot system capable of manual battery replacement. Generally, a smart farm refers to a type of intelligent farm that minimizes the need for human labor by automating agricultural techniques through the integration of information and communication technology (ICT). According to this smart farm technology, the temperature, humidity, amount of sunlight, carbon dioxide, and soil of a crop cultivation facility can be measured and analyzed using Internet of Things (IoT) technology, and the growth status of the crops can be analyzed. Based on the analysis results, an automated system can be operated to cultivate crops in an optimal growth environment, and remote management via mobile devices such as smartphones is also possible. It is also possible to automatically spray fertilizer and insecticides for pest control. Meanwhile, although such smart farms can be installed in various forms and at various costs depending on the system configuration, they typically require a significant investment. Consequently, research is currently being conducted on open-field smart farms, which are more affordable to install compared to greenhouse-type smart farms. The aforementioned open field refers to land not covered by a roof, and in agriculture, it signifies rice paddies and fields where facilities are not installed. However, while it is desirable to perform leveling work first to manage the aforementioned smart farm, in the case of open-field smart farms, the smart farm system may be installed on unleveled open land (e.g., orchards, highland vegetables, etc.) due to the characteristics of the open land. Furthermore, even if leveling is achieved, the land may be deformed into a non-leveled state due to the influence of wind (typhoon), rain (heavy rain), sunlight (heat wave), etc. Therefore, there is a need for an autonomous driving robot system capable of managing such open-field smart farms. Meanwhile, autonomous mobile robots are equipped with internal battery modules and drive using power from these modules. Here, a rechargeable battery is used for the battery module; to charge the module, the mobile robot docks with a charging station to recharge it when the module is discharged. A typical example of this is the robot vacuum cleaner used in homes, which automatically docks with a charging station to charge. However, in the case of open-field smart farms, even if charging stations are installed, the characteristics of the open field make it difficult for mobile robots to dock at the precise docking position for charging. As explained earlier, even in open-field smart farms where the ground has been leveled, environmental factors can damage the leveling, making it practically difficult to implement charging for mobile robots using charging stations. In addition, since the charging station is installed outdoors, it is difficult to completely block external moisture or rain, so the risk that the device itself may be damaged due to accidents such as short circuits during charging cannot be ruled out.
