The application discloses a method for rotating a light real-time controllable zinc oxide microrod. The method is realized by interaction between a spatial electric field generated by focusing laser irradiation on lithium niobate and a zinc oxide microrod, so that the zinc oxide microrod moves in a two-dimensional plane. By adjusting different end face positions of the zinc oxide microrod irradiated by the laser, the rotating direction of the zinc oxide microrod in the two-dimensional plane can be effectively controlled, and the rotating speed is controllable. In addition, by adjusting the laser intensity or changing the length of the zinc oxide microrod, the rotation of the zinc oxide microrod in a three-dimensional space is also successfully realized. The method has important significance for research and development of micro-lasers and integration of photonics chips.

This invention discloses a cargo handling method and system. The cargo handling method uses a camera component located on the front side of a mobile chassis or the side of the first axis of a handling robot to capture images. This reduces the distance between the camera and the front side of the mobile chassis, preventing the camera's field of view from being blocked by the mobile chassis. The camera component tilts the highest camera downwards to take pictures, while the other cameras tilt upwards to take pictures. This allows for full coverage of the cargo stack height when the distance between the handling robot and the cargo is small. Furthermore, the entire handling process does not require vertical adjustment of the camera's viewfinder. The three cameras allow for a relatively small vertical field of view for each camera while ensuring coverage, thus improving the accuracy of the captured images. Additionally, when the target image is acquired, handling is preferentially performed from the top surface of the cargo, resulting in more reliable handling.
