This article deals with the design and construction of a robotic vehicle. The first part of the paper focuses on the selection of suitable variants for the robotic vehicle arrangement, i.e., frame, electric motors with gearboxes, wheels, steering and accumulators. Based on the selection of individual components, the robotic vehicle was built. An important part of the robotic vehicle was the design of the suspension of the front wheels. The resulting shape of the springs was experimentally developed from several design variants and subsequently produced by an additive manufacturing process. The last part of article is devoted to the experimental measurement of the acceleration transfer to the upper part of the frame during the passage of the robotic vehicle over differently arranged obstacles. Experimental measurements measured the accelerations that are transferred to the top of the robotic vehicle frame when the front wheels of the vehicle cross over the obstacle (obstacles). The maximum acceleration values are 0.0588 m/s in the -axis, 0.0149 m/s in the -axis and 0.5755 m/s in the -axis. This experimental solution verifies the stiffness of the designed frame and the damping effect of the selected material of the designed springs on the front wheels of the robotic vehicle.
本文论述了一款机器人车辆的设计与构造。论文的第一部分着重于为机器人车辆布局选择合适的变体,即车架、带变速箱的电动马达、车轮、转向装置和蓄电池。基于各个部件的选择,制造出了机器人车辆。机器人车辆的一个重要部分是前轮悬架的设计。弹簧的最终形状是从多个设计变体中通过实验得出的,随后通过增材制造工艺制作而成。文章的最后一部分致力于在机器人车辆通过不同布置的障碍物时,对传递到车架上部的加速度进行实验测量。实验测量了车辆前轮越过障碍物时传递到机器人车辆车架顶部的加速度。最大加速度值在x轴上为0.0588米每二次方秒,在y轴上为0.0149米每二次方秒,在z轴上为0.5755米每二次方秒。该实验方案验证了所设计车架的刚度以及所选设计弹簧材料对机器人车辆前轮的减震效果。
