A robot arm without a hand

[TangoBear]

Hey Guys,

I'm new here and i'm a rookie in making robot arms,
so i decided to make one, but without a hand on it, just a square platform, and i should place a sort of case, but i just want to make a robot arm, i know in theorie, that you need servo's, strongs servo's, and maybe a printed a circuit board, etc... but euhm i dont know where to start :S
i want to make it with a button, if i push it that it comes out and maybe after 5 sec. that it returns into the position where it started.
Can some one help me?
I have a Picture i drawed on paint ^^ http://imageshack.us/photo/my-images/3/teston.png/

I hope this helped to solve my problem :S

Regards, TangoBear

Sorry, but I don't understand what You've drawn in Your images. Would You consider using CAD? That's beneficial to You, as You can then feel actual dimensions of Your robot, and also You can share that data with others and others will understand it.

I'll try it with solid edge,

I'm sorry but i'll draw it again with paint, because it gonna take me for years to put it on solid edge, i'll draw it more precise what i want

[TangoBear]

i re drawed it more specific, i hope you understand it now a bit.

Are You kidding me? Just get Autodesk Inventor and You'll be rocking and rolling in no time

[...] i know in theorie, that you need servo's, strongs servo's, and maybe a printed a circuit board, etc... but euhm i dont know where to start :S

Strong can not be measured in units, so in engineering this term is not useful  To know what torque (strength) each servo must have, You need to know the weight and length of each link of the arm, plus You need to know what will be maximum weight of the load robot is going to handle. Without these You cannot progress any further.

Regarding printed circuit boards, they are not necessary for Your robot to work, everything can be placed on a simple prototyping board.

wow.  your drawing is horrible.
