竞赛机器人小车设计的几个关键问题及解决

介绍了竞赛机器人小车的设计和具体实现。机器人小车以SST公司的SST89E564RD单片机为控制器，辅以传感器模块和驱动器模块。传感器模块采用的是反射式可见光传感器，利用达林顿管对反射光强进行放大。控制模块采用传感器信号来确定小车状态和辨认路线，依据直行算法控制机器人小车进行直线行走，通过预置导航地图来改变小车的前进方向，从而达到自主寻迹的目的。

The Solutions to Several Key Problems about the Design of a Vehicle-like Robot for Competition

With reference to a robot competition, this paper has introduced the design and implementation of an automatically guided vehicle-like robot. The robot is designed with SST89E564RD MCU as controller, assisted with the sensor module and drive module. Reflectional visible light sensor that can magnify the intensity of reflectional light by Darlington transistor is adopted in the sensor module. By sampling voltage signals from the sensor module, the controller can identify the state of the robot and recognize the route. Then the car-like robot would be told to go straightly according to the straight-moving algorithm. With the combination of preset navigation map, the controller can change the direction of the robot. As a result,the purpose for the robot to be auto- matically guided has been realized.
