Abstract
Smart car as a modern new invention is the future direction of development, in an
environment where it can operate automatically at preset mode, without human management
can be applied to the use of science exploration, dangerous jobs, etc.. Therefore, the research
and development of intelligent car control system has great significance.
The design is based on China Robot Competition and RoboCup Open "robot tourism"
project as the background, using STM32F103ZET6 as the master chip, designed and
manufactured a person intelligent tracking car. This paper takes the form of expanded score,
first from the overall design of the car to be a simple overview, and then were small cars
hardware architecture and software design are described in detail.
Car from the chassis and humanoid upper body composition, using a complete two
half-bridge driver IC + low resistance N-channel MOSFET drive motor constructed role in
grayscale sensors, infrared sensors and touch switch feedback signal Next, the car can achieve
forward, backward, turn left, turn right, and other basic functions, you can self-identify
placement of barricades, find the best route and arrive at the voice broadcast attractions;
humanoid upper body constituted by the eight servos, Each joint can move freely, but also for
the future practice tasks possible. Sensors will be collected signal to the microcontroller for
processing, and then issued by the main control system corresponding control signal to the
motor driver to control the car to achieve self-recognition in a predetermined path venues,
independent travel, attractions and self-touching language broadcaster, finalize the "Travel"
task.
