How To Make Your Own Robot Controlled With C#, Followed By A WebCam.

Hello my dears followers, Like it is mentionned in the article title. Today i m going to demonstrate how we couldmake an intelligent robot, Controlled by your own C# application made in Visual Studio 2012, Followed by aWebCam.

To Make a full project like this one you have many choices to choose.

The Hard part of this project is done using an Atmega 328p like a principal MCU. You could use any other MCU,For exemple A PIC like PIC16F877 is able also to replace the Atmega328p.

We know that the principal MCU based on the Arduino UNO is ATmega328 so You Could also use Arduino to getthe robot working.

Those Kind of project based essentially an serial communication. so you have just to use a MCU able to supportUART.

There is a step in my project based in PWM so the MCU used have to support PWM also.

And for those how dont know what that means UART and PWM they have just to take a look here:

ATmega 328p pins

ATmega 328p

I choosed directly the ATmega 328p because this one is easier in programming and cheap in price.

The robot move in 4 directions using a 4 simple DC motors, and those motors are controlled by 2 L293D.The camera is just placed in the first servomotor. and this one is place in other one to get sure that the positionwhere the camera is putted could cover every point.

I showed in this article programming ATmega like an Arduino how to program an ATmega32p like programming asimple arduino. this solution is used todayalso and this is the full program placed inthe MCU memory to make the robotmoving.

{ int i6 = myservo1.read(); myservo1.write(i6 + 1);}

This is The Complet Circuit that you have to draw.

TheHardpartofthe

project is just done so let's talk about the soft part.

We have here to build an Application based in serial communication able to connect directly the robot.

There is many solution to do this, for exemple Labview is one of the best interfacing system also Visual Basic orC#.

I used C# to do this. A simple application in one only panel with a serial communication platform.

Many Buttons to control the robot and the camera.

How The Application Work ?

This is simple, We have just to add a serial platform to the app. This one will always ask for the port com and thebaud rate. Since the moment your choose your serial parametres the fonctionnemnet of buttons starts.

Every button you will click will send a code to the MCU and exactly like this that's working.

How the WebCam Works ?

In fact, there is a direct library you have to add to your visualstudio named AFroge.net Direct Download. After adding this oneto your visual studio you have to add this two reference to yourproject.

The rest is easy, you have just to give the application the permission to look for webcam devices plug in yourcomputer, starts showing what she see, Capture button to save directly the view.

This is the full program written with C# in Visual Studio 2012.

Built your application, Get your file.exe and the Setup. Like always this is a video for more details.

I have all files of this project collected in compressed directory so just contact me to have your free files.

See you Soon AYMEN LACHKHEM
