i need ur help , i want to construct a robot in a ceiling through a rail in a house , this is my graduation project...
using it for security reasons... including a camera and sensors... but i need a flowchart of how it could work.... thank you ???

Since this is YOUR project, you should be giving us the flow chart of how you think it should work. Then we can help you refine it and suggest methods to accomplish the objectives.

so what precisely are you asking? there are many ways to do everything you ask and you at least need to have an idea of what you want to do which you have but more importantly how you want to do it. if you have that then you need to tell us! information is our food and you must feed us! with that being said i'll go over the basics of what we tell everyone.
1) you need a controller
A controller is anything that can run a program of your own design to control your machine. this can be anything from a computer sending data through the serial or parallel port, a micro controller which is basically a tiny computer on a single board or chip, a remote control for RC planes or cars or an program free circuit that uses something like a 555 timer or an op amp chip but this is much more complicated. if your project is stationary (like a robotic arm) then an old desktop can be just as functional if not more so then a microcontroler but relies on the fact that the object can be tethered whereas a microcontroller can be powered from batteries and is small enough to control a moving robot. this is essentially your robot's "brain" and is how you tell your robot to do what it does so you must base your decision accordingly. another thing you should think about is that the software you create for your robot is free and weightless making any solution that that can be solved with software much more economical.
2) decide on a mechanical system
this is a bit more tricky. you have to think of a number of things when deciding on this including what you want to spend, what you need it to do, how effective and reliable each method is over the other and how much you want to program it. remember that you have to tell your robot how to use each moving part it has and that generally speaking moving parts are more expensive then static parts (i.e. a wheel with 1 motor is cheaper then a 2 servo hexipod leg).
2) choose what you want to make yourself or what you want to buy.
remember that allot of things you can buy can be made for cheaper. just look at the microcontroller for the $50 robot. on the flip side there are things that you CAN'T make yourself or that arn't economical to make. look around for ready made things to save you money and time.
