Week 2:Machine Learning of Pixy 2

In this lab section, the research group managed to activate the pixy 2 camera with a given driver. By using the driver, the research group could cheek whether the camera could run smoothly.

Then, the research had to enable the SPI and I2C service in the raspberry pi and introduce the python library module to the raspberry pi for the Pi2go MK2. In this way, all kinds of sensors and motional devices could be activated when necessary.

Having activated the camera, the research group began to try the machine learning part of the program. In specific, the car needs to recognize different kinds of barriers and send alerts to the pi and have the pi to judge how to change the moving direction to avoid hitting.

The machine learning part is the fatal part of the car. Firstly, the research group managed to do this from a simple task which is to recognize a sign written on paper. The detailed learning and recognition procedure are shown in the video.

Week 4: Change of Operating System and Problems

Change system and problems In the lab section of this week, the research group had a difficult time. In detail, it is difficult to have the video of the camera been transmitted to the computer. The data flows to the raspberry in the form of coordinate, length and height of the marked blocks. In this way, the processor of the pi could be relaxed. However, in the first place ， the basic function of the car is that the user could see what the car sees with the use of camera. If the control system is not visual, it is meaningless to have such a complex system. To make it possible to visualize the streaming video, the research group checked the driver of the camera. It turns out that it is not designed for Raspbian, and this made its function been limited to this system. To solve this problem, the research group had to change the system of the smart car and recode the programs that have been tested. In specific, the driver is designed for a pure Linux environment. Having don...

Week 1: Car Assembling and Raspberry Pi Initializing

Pi2go MK2 Smart car assembling and introduction: In the first week of the project, the research group received the components that will be used in the project. The first thing to do is to assemble the smart car Pi2go MK2. In specific, Pi2go MK2 contains a chip which could control different parts of the car. The raspberry pi uses the GPIO connections to control and power the smart car. Figure 1: GPIO pins to control the car System instaling: Having assembled the car, the research group began to initialize the raspberry pi. According to the instruction, the research group had to instore an operating system into the SD card with SD card formatter and Win 32 Disk Imager. Problem-solving: However, when the raspberry is equipped with the operating system and plugged into a screen, the screen showed the following alert: kernel failure. To solve the problem, the research group tried to restart the pi for several times and it still shows a failure. Then, the researc...
