+ for myself and other supporters
+
+ -a complete system of detecting shapes and zcodes while controlling the robot arm system

+
+ -Using python to make it with raspberry 4B
+
+ -with ZhongLing Tech Company Servo and Uno MCU.
+
+ -Six degree of freedom robotic arm
+
+ -2 Pwm Servos and 4 Bus servos
+
+ -including two kinds of solutions
+
+ -1:Deriving an action through the inverse of the final coordinate point and is inverse kinematics
+
+ -2.Forward kinematics, which directly adjusts the angle of each servo for control, is relatively rigid and can only rotate a fixed angle
+
+## The file structure
+
+arm_control.py shows the inverse kinematics mean to control the robo_arm
+
+cluster.py shows the basic way to use opencv to detect things.In this program,I use the python-opencv lib to invoke it.
+
+And it shows the way to detect different colors with RGB
+
+shapes.py shows the hough circle algorithm and edge point algorithm to detect triangle and rectangle.
+
+uart.py shows the basic usage of uart agreement.And I provide two ways to use it.You can use it with single threading or multiple threadings.
+
+zcode.py uses the pyzbar lib to detect zcode.
+
+word_detect.py is the final solution to use it.As I use it in the contest that is no longer available to other programs.So I just didn't show it all.
+
+##The progress
+- [x] finish the program
+- [x] can use with uart
+- [x] can use with raspberry pi all series
+- [ ] can't use with other brands of ARM development board as it uses pi's special lib
