Hi there. I am an advance diploma student and planing to build a robotic arm as my personal student project. Here's the idea: the arm will move following the motion of the user arm, that it, moving in 4 directions, grasp and wave as controller does. The user maybe wearing something like a glove to control the arm. However the problem is I have no any experience in robotic. Therefore i like to ask your opinion. Will this too beyond for a newbie in robotic? and will building this robot too expensive?
