Hi, this kind of dumb thread... Anyway, before you get into wireless communication, you have to do a lot of planning, thinking and research for the mechanical portion of your project.
First, the hand... What are you going to manipulate with it? How will it grasp, bend, or turn, range of motion. strength and precision? Tactile sensors or simple limit switches?

Second, the arm... Obviously, the more complex the hand, the more it will weigh. You will need to design this to handle the weight, plus whatever kind of work you plan for this project. Also, how many axis of movement, range of motion...

Third, what do you plan to use move these parts? Motors, gears, chains belts cables, solenoids, air cylinders. Motors... servos and steppers need even more electronics to control...

Fourth, feedback... you need to know the position of all elements. Simple limit switches can it from damaging itself without interaction, but you will need to keep track of the exact position of each axis. Since rotational motion is going to be a huge part, how do measure this?

This has gotten very long, just gettin to the electronics to deal with the mechanical elements... Your wireless question... is well, a year or two premature.

hey i need same kind of circuit......kindly help.

Hey... g khl, hiyan, and others... I found a link that you may find usefull.... it's a source that I use extensively and contains more info than you will have time to read...I always spends at least a day trying to find the info that I'm looking for from this source before I ask any questions. The source is www.google.com Try a couple of searches....

I want cicuit design of robotic arm if available. Pleas help.
Thank you.

The site given by you is not opening. bloody orc

I think this site will help you to desigen the robotic arm. Actually, it is a robotic arm project.
