Abstract
Description
Technical Field
[0001] This utility model relates to a ground-walking robot for inspecting farms, belonging to the field of inspection robot technology. Background Technology
[0002] With the development of technology, traditional individual farming has shifted to large-scale and collective farming. In order to meet the needs of large-scale farming management, technologies such as automation, intelligence, and digitalization have begun to be developed and applied.
[0003] One of the main tasks of large-scale farming management is to monitor the growth status of products and the surrounding environment in real time. However, manual inspection has many drawbacks, such as low inspection efficiency, high labor costs and high workload, high requirements for the professional knowledge and skills of inspectors, significant human factors, uncertainty and the possibility of misjudgment, and harsh working environment with certain health and safety hazards. Therefore, the applicant previously disclosed a track-type robot for farm inspection in patent CN202321018415.2. This track-type robot includes a mechanical cavity and an electrical cavity located at the bottom of the mechanical cavity. The top of the mechanical cavity has a track connection port adapted to the inspection track. The mechanical cavity contains a drive mechanism, and the electrical cavity contains a power supply and a servo controller. The servo controller is electrically connected to the drive motor, and a camera is located at the bottom of the electrical cavity. Both the servo controller and the camera are signal-connected to the main controller. While the track-mounted robot provided by this patent can operate stably on inspection tracks of various specifications and types, constructing an aerial track within a farm presents a high construction cost issue. Furthermore, aerial inspection robots may malfunction and fall, potentially damaging or injuring products within the farm. Therefore, it is necessary to develop ground-based inspection robots suitable for use in farms.
[0004] The environment inside farms is typically complex. For example, farms often include various terrains such as muddy areas, waterlogged areas, slopes, and steps, resulting in uneven ground surfaces. This places high demands on the mobility of ground-based inspection robots. Furthermore, the narrow passageways and densely packed equipment inside pigsties create limited space, requiring ground-based inspection robots to move flexibly within confined areas and actively avoid obstacles. Existing wheeled inspection robots are prone to tipping over and vibrating when navigating uneven and complex terrain, thus failing to adequately meet the automated inspection needs of farms with such complex environments.
