  • Patent number: 11918713
    Abstract: The present disclosure provides a high-temperature negative-pressure air exchange sterilizer and a sterilization method thereof. An air inlet is disposed at a bottom of a waterproof shell of the sterilizer, and an inlet filter is installed at the air inlet. Air entering from the air inlet is divided into two paths at a check valve. One path is connected with a negative-pressure fan through a pipeline B, and the other path is communicated with an air outlet through a pipeline A. A plurality of heating rods and temperature sensors are disposed in the pipeline A. The pipeline A is zigzag disposed at an upper part of the waterproof shell, and a thermal insulation material is disposed outside a zigzag part. A butterfly valve and an outlet filter screen are sequentially disposed at the air outlet in an air exhaust direction. The problem that viruses exhaled by breathing of an infected person are mixed in aerosol, so that a person in close contact with the infected person is likely to be infected is solved.

  • Publication number: 20230271318
    Abstract: A robot state planning method based on a Monte Carlo tree search algorithm. The method comprises: obtaining an initial state and a target state of a robot (step 100); by using the initial state as a starting node, using a Monte Carlo tree search algorithm to expand a Monte Carlo tree until a generated target node reaches the target state (step 200); and determining a state sequence of the robot according to all nodes from the starting node to the target node (step 300). According to the solution, the overall state in the motion process is planned, and a state sequence is generated; thus, effect of front back coupling caused by planning according to periods can be avoided, and the passing capability of a six-foot robot in a complex terrain is improved.

  • Patent number: 11377162
    Abstract: A soft biomimetic legged robot is provided in the present invention, including a plurality of soft robotic arms. The soft robotic arms include a plurality of motion units, and each of the motion units includes one or more of a twist module, an extension module, a contraction, and a bending module. The plurality of motion units is combined to achieve a full-posture motion of the soft robotic arms. By using soft robotic arms composed of different motion units, the soft biomimetic legged robot of the present invention can not only realize the underwater swimming and crawling, but the crawling on land or slopes, thereby adapting to more complicated environments and achieving richer functions. The motion posture is not limited to a single bending, twisting, extension, and shortening. The soft robotic arm can achieve full-posture movements, and its motion type is more complete.
