Feasible robotic arm

[entropie]

I am looking for a robotic arm to study it and to help me with my work. I am working a lot on electronic boards and having an arm holding the boards in midair so I can solder them would be a great help. Plus I could need it for hand milling and graving small parts.

I know a bit about the mathematical principle of forward and backward transformation and could almost build an robotic arm with servos and an AVR myself. A dream would be to build two arms as an extension to the own body but I think I'll be too afraid to put a thing like that on, if it goes highwire I dont want to turn into Doc Oc from spiderman .

I've found that one, does someone by chance have experience with it:

It says the thing lifts up to 100g. If thats g for Grams, it would have a bit to less power. if thats g for earth acceleration it would be ok, but I dont believe the latter one.

So if someone has experience or knows of a good project, please lemme know. Thx.

Why stop at 2?

Why not 8? Octoman?

There was an evil guy in some Indiana Jones novels who had a robotic arm, I think he may have been a nazi archeologist too.

Uh, back in the days I'ld prolly have been a nazi archealogist too. That or rocket science.

Well you start with 2 arms, then go to 3, then 4, then 5, etc.. That makes the development easier, cause when you start with 8, it may suffer from problems that relate to 2 and you wouldnt know that since you started with 8
