How to control movement

hi ,

    i would like to know that is there any method of designing a robotic arm which is controlled by imitating the movement ,that is , it follows the movement of your arm with same speed and acceleration. 

if yes then tell me the components to make the controller.

Look at this mini robot arm.

Look at this mini robot arm. The 2nd video shows nearly the same behaviour that you want.

but what about conrollers

yeah i have watched that video that’s why i also want to make that arm

but  it don’t  tell about the components and how to join them dat’s wat i want

Looks pretty straight

Looks pretty straight forwards, number of servos = number of potentiometers, it could be done with a logic circuit.
