摘　　要：本文研制的全地形小车结合了四轮越障车越障能力强劲的特点,以铝件作为结构框架,并以树莓派4b板为核心微控制器,触须传感器和灰度传感器为辅助控制系统,直流减速电机为整体驱动系统,还采用卡尔曼滤波算法和增量PID控制算法控制小车整体的稳定运行,精确地控制小车的行进线路和行进姿态。该全地形小车能够适应多种场地,并在启动后能够自主实现沿着黑色引导线行走、攀爬窄桥、跨越两段式阶梯、过隧道、识别指定颜色的气球并爆破,最后在终点线处停下。该车全程行驶过程中,均无人干预和操控。The all-terrain car developed in this paper features the strong crossing ability of four-wheel obstacle crossing vehicles,with aluminum parts as the structural framework and the raspberry pie 4b board as the core microcontroller.Tentacles sensor and grayscale sensor is used as the auxiliary control system,and DC deceleration motor is used as the overall drive system.Kalman filter algorithm and incremental PID control algorithm is used to control the overall stability of the car,which accurately controls the travel line and movement attitude of the vehicle.The all-terrain vehicle can adapt to a variety of venues.After the start,it can independently walk along the black guide line trail,climb narrow bridge,cross two section ladder,go through tunnel,identify balloons of specified color and explode them,and finally stopp at the finish line.During the whole driving process of the vehicle,there is no intervention and control from anyone.
