    Improved Clonal Selection Algorithm Based on Biological Forgetting Mechanism by Chao Yang, Bing-qiu Chen, Lin Jia, Hai-yang Wen

    Published 2020-01-01
    “…This part of inactive antibody forms a “black hole” of the antibody set, which is difficult to remove and update in a timely manner, thus affecting the speed at which the algorithm approximates the optimal solution. Inspired by the mechanism of biological forgetting, an improved clonal selection algorithm is proposed to solve this problem. …”

    Mechanism Design and Simulation Analysis of Deformable Wheeled Mobile Robot by Peichao Cong, Junjie Liu, Xinjie Feng

    Published 2021-08-01
    “…Aiming at the problems of the deformation wheel posture adjustment and lower step buffering of the current deformable wheel mobile robot, a novel deformable wheel mobile robot is designed based on the mechanical self-locking principle. With the self-locking effect between the "push rod" and the "plane screw pair", the lifting universal wheel mechanism is set up, which effectively solves the "wheel plate retraction" phenomenon of the deformation wheel, and optimizes the mechanism of the system control. …”
