Anyone interested in creating a team to brain storm ideas and designs for robot arms for large or small robots. Perhaps collectively we could come up with a universal design that many of us could use. We each could provide input, drawings and/or services.

irobot58, cool arm and kinda creepy. I love it! Now, just don't try to do what Howard did on Big Bang Theory and end up in the Emergency Room! *eek*

I saw that Episode of Big Bang and LMAO! The total arm will be heavy but plan on either a DC motor for the shoulder and or bungees for tendon assist.

This thread is very informative about servos and math torque but I think a very direct way of knowing what kinda servo with how much torque , can be done by simply measuring the actual torque with a spring guage! They're easy to build using a spring ( and if you dont have a reference scale for calibration you can always take it to the supermarket and use their scale|) or bungee cord! Cheap fishing scales are usable as well and most of us probably have those in the garage behind the net! ..... Add in all the known payload..ie A can of Moosehead Beer(micro brewery) or the glass of wine for the Ladies.! Its the old ..which came first, the chicken or the egg(egg actually) ...build the arm or buy the servo first:)
