Hello everyone.I am here to introduce my little car.
First, we need a STM32 to drive the for wheels and transfer some data of these sensors such as mpu6050 idom through the usb.
Next，we need a Nano2gb to establish ROS， then we create packages in ROS as talkers and listeners in order to receive the data from STM32 and Laser which is a independent sensor and publish to driver.
Finally， the car can established a map wherever you start the car，and it can also move on this map up to your order.
Sorry, I am poor at English, I am Chinese. And I can not put my codes on github because of the restricted web. So,please watch the picture below which may make you understand easily.Sorry for my poor English
