    Is this a serious effort? You have selected a topic, but have turned to us to produce it for you? And give no details at all.

    We will help with projects, but do not produce them on demand. We must insist you make the effort to research the hardware, design the interface, select a suitable controller, and do the coding. It is for a grade, so you must do the work to earn the grade.

    but i need help as in how to interface an accelerometer with any motor (to drive the arm)??i have done a lot of research in my field but pardon my way of asking the question was pretty open and rude.

    You will probably need a 3 axis accelerometer to sens arm motion - perhaps mode is the arm is jointed. The outputs will have to be conditioned and read by a microcontroller (probably pretty high power for this application). The microcontroller, directed by a program, will control a number of motors to actually move the arm. Some input to the microcontroller to direct it may be necessary.

    This might be easier with stepper motors running the arm, but it's still a lot of work. Do you need to construct the arm as well?

    what do u suggest ??
    shud i construct the arm or buy 1 ???
    )finance is also my concern in the project.)

    but i have lots of queries that which microcontroller should i use atmega16 or 32 and ?shud i directly interface the triaxis accelerometer with the microcontroller??
    i also need make this project wireless between the arm and accelerometer would that be possible????

    Knowing nothing of your background, I can suggest almost nothing. If this is all new to you, you really need to do some research to see what you are comfortable getting into.

    Please think about that question. How could it be possible?

    Do you understand how an accelerometer works? If it is not attached to the moving parts of the arm, how can it sense motion?

    Do yourself a favor, and Google "accelerometer chips". You get hits like this - http://www.sensorsportal.com/HTML/SENSORS/Accelerometers_Manuf.htm Use the sites to obtain data sheets. They explain how the devices work. You have to know how things work before you can design with them.

    which software shud i use to simulate my project hardware??
    i have a design but i need to test it virtually first.
    i tried on "proteus" but it doesnt have accelerometer control.

    Someone else needs to step in about that subject. I have no experience with those simulators.

    Hey Raaj,

    I think a lot of these questions are good questions for your professor. I suspect you're biting off more than you can chew. Embedded systems, control systems, wireless communications, mechanics... this is alot for one person for one semester if you are starting from scratch (i.e. building your own mechanical arm...). Heck, that's a lot for a GROUP project even. Plus choosing your own hardware is not an easy task for a first timer... there's usually lots of trial and error there.

    In my opinion, you need to work with your professor to narrow the scope this project and have HIM give you the electronic hardware so that you will have his help as a resource.

    i have attached the layout developed by myself ..along with it i have provided the details in bracket. i just want to know if i am goin right ??

    are there any flaws in basic blocks?? or did i missed something???

    see the attachment

    Your block diagram seems okey just start implementing step by step.
