Description: The Pololu 3pi robot is a small, high-performance, autonomous robot designed to excel in line-following and line-mazesolving
competitions. Powered by four AAA batteries (not included) and a unique power system that runs the motors at
a regulated 9.25 V, 3pi is capable of speeds up to 100 cm/second while making precise turns and spins that don’t vary
with the battery voltage. This results in highly consistent and repeatable performance of well-tuned code even as the
batteries run low. The robot comes fully assembled with two micro metal gearmotors, five reflectance sensors, an 8×2
character LCD, a buzzer, three user pushbuttons, and more, all connected to a user-programmable AVR microcontroller.
The 3pi measures approximately 3.7 inches (9.5 cm) in diameter and weighs 2.9 oz (83 g) without batteries.

Description: The 3pi robot [http://www.pololu.com/catalog/product/975] is complete mobile platform designed to excel in linefollowing
and maze-solving competitions. The 3pi has user accessible I/O lines that can be connected to different
sensors to expand its behavior beyond line-following and maze-solving. This project shows just one possible
configuration where two Sharp analog distance sensors are connected with minimal soldering. Many other sensors
could be used to expand the 3pi: a radio-control receiver could make an RC 3pi [http://www.pololu.com/docs/0J37.a] gyro
could enable precision spinning, a sonar range finder [http://www.pololu.com/catalog/product/723] could improve the
3pi’s sensing range, and a digital distance sensor [http://www.pololu.com/catalog/product/1134] could offer speedy front
obstacle detection!

Description: Gabor滤波器经常被用于形状检测和特征提取，比如增强指纹图像。本代码用matlab实现了一个二维Gabor滤波器。
代码使用如下：
function [G,gabout] = gaborfilter1(I,Sx,Sy,f,theta)
from gaborfilter1 with different f(Frequency) and theta(Angle).
for example
f:0,2,4,8,16,32
theta = 0,pi/3,pi/6,pi/2,3pi/4
then for any input image like(eg. stereo.jpg)
you have 6x5 = 30 filtered images.
You can choose your desired angles or frequencies.
You can put nominaly Sx & Sy = 2,4 or some one else.
For instance I tested above example on ( cameraman.tif )(in MATLAB pictures)
I = imread( cameraman.tif )
[G,gabout] = gaborfilter1(I,2,4,16,pi/3)
figure,imshow(uint8(gabout)) -Gabor filters are often used for shape detection and feature extraction, such as the enhanced fingerprint image. Matlab implementation of the code is a two-dimensional Gabor filter. Use the following code: function [G, gabout] = gaborfilter1 (I, Sx, Sy, f, theta) from ' gaborfilter1' with different f (Frequency) and theta (Angle). For example f: 0,2,4, 8,16,32 theta = 0, pi/3, pi/6, pi/2,3 pi/4 then for any input image like (eg. stereo.jpg) you have 6x5 = 30 filtered images. You can choose your desired angles or frequencies. You can put nominaly Sx & Sy = 2,4 or some one else. For instance I tested above example on (' cameraman.tif' ) (in MATLAB pictures) I = imread (' cameraman.tif' ) [G, gabout] = gaborfilter1 (I, 2,4,16, pi/3) figure, imshow (uint8 (gabout))

Description: 本设计以MCU为控制核心,使用迷宫算法与机器自主学习的思想核心和电机PID调速为运动核心的一款智能迷宫小车，通过对传感器的加权平均处理进行高精度数据采集，将连续性变量转换成离散随机变量。首先根据左手运算进行迷宫整体搜索，然后进行数组记忆和最优路径运算，第二次进入赛道5秒逃出迷宫。(This design takes the MCU as the control core, uses the maze algorithm and the machine independent learning core and the motor PID speed control as the core of an intelligent labyrinth car. Through the weighted average processing of the sensor, high precision data acquisition is carried out, and the continuous variables are converted into discrete random variables. First, the maze search is done based on the left hand operation, and then the array memory and the optimal path operation are used to escape the maze second times into the circuit 5 seconds.)
