Description

A manned/unmanned logistics transfer robot The present invention relates to a transport robot, and more specifically, to a manned/unmanned logistics transport robot that can be selectively operated in either a manned mode or an unmanned mode, and is suitable for miniaturization and can be utilized in narrow spaces by minimizing the turning radius at low speeds using an inverse phase steering method for forward/rear steering. As South Korea enters a society characterized by low birth rates and a super-aging population, the number of workers in direct labor sectors, such as agriculture and logistics, is significantly decreasing. As a solution to this social problem, the development of robots to replace these manual laborers is actively underway. Many companies are managing the locations of various products and materials within logistics warehouses using transfer robots. Transfer robots are robots that perform the task of moving goods in warehouses or factories. The functions of transport robots can be divided into driving technology, in which the robot moves directly to transport items to a desired location, and manipulation technology, in which robotic arms are used to pick up, load, collect, sort, and package items. Such transport robots can operate effectively in large-scale logistics centers. When transporting or handling harvested crops in rural areas, or when repeatedly moving boxes and items of various sizes in small logistics centers, using transport robots designed for large logistics centers is not effective in terms of both economics and technology. Therefore, there is a need for a transport robot that can be effectively utilized in rural areas or small logistics centers and can selectively operate in manned and unmanned modes. The required transport robot must be capable of moving together with the worker within a certain distance when the transport robot performs its inherent functions as a worker near the transport robot directly or indirectly directs it in manned mode, and must be capable of autonomous driving along a path predetermined by the user in unmanned mode. In particular, transport robots intended for use in rural areas or small logistics centers must be compact; however, conventional logistics transport robots have a turning radius that is inversely proportional to the radius of the wheels at both ends from the center point of the platform due to forward or backward steering, and this disadvantages the miniaturization of logistics transport robots. In particular, conventional transport robots have the disadvantage of being economically burdensome to use in rural areas or small logistics centers because they require expensive equipment such as depth cameras or 3D LiDAR to obtain information necessary for movement, and precision machinery such as robot arms are required, along with high manufacturing costs.
