Self-adaptive loading and unloading platform and method Technical Field The invention relates to the technical field of movable robots, in particular to a self-adaptive loading and unloading platform and a self-adaptive loading and unloading method. Background In the field of automated logistics, mobile robots (AGVs/AMRs) have become key devices for improving warehouse and handling efficiency. The traditional loading and unloading robot usually adopts a single-piece operation mode that the robot moves to a picking point, a set of picking and placing mechanism loads materials to a bearing platform of the robot, then the robot integrally moves to a target unloading point, and the same set of mechanism unloads the materials. After the process is completed, the robot can return or go to the next pick-up point for the next operation cycle. This sequential mode of operation presents a significant technical bottleneck. At any moment, the core execution component (such as a mechanical arm) and the bearing platform of the robot can only serve a single loading and unloading task, when the robot performs unloading operation, the taking and placing mechanism and the bearing platform are occupied and cannot simultaneously execute loading operation, and vice versa. This results in a great deal of functional idle time of the key operating unit of robot, especially when getting goods the point and getting the distance of unloading the point far away, or the material is put things in good order and is needed fine operation, its effective work rate reduces by a wide margin, and the material turnover volume in unit time receives fundamental restriction, is difficult to satisfy modern commodity circulation to the urgent demand of high throughput. In addition, existing loading robots often lack flexible adaptation capability in the face of complex scenarios with multiple discharge points. The operation range of the mechanical arm is fixed, and if the unloading area is larger or distributed at different positions, the robot usually needs to adjust the position through integral movement, so that the complexity of an operation path is increased, the single operation period is further prolonged, and the application efficiency of the mechanical arm in a limited space or a high-density storage environment is limited.
