Re: pic: arm design
Alright, you guys are right. What I meant was I, or anyone I know, would not want to tackle this design this late in the game. Maddie Krass, I'm sure you could finish it in a few days, but that in no way means that the best way to "inspire" someone would be to suggest something beyond their capabilities.
And Stephen, I wasn't criticizing you for your lateness.
Now if you want some serious suggestions:
Get rid of the second joint in the arm. With a nice gripper, it is possible to reach the center goal with a single jointed arm.
Power the main joint in the arm with at least one fisher price or Sliding door+globe. You need the power with the 100+ft-lb of torque you will be looking at.
It looks from your design that you are planning on transferring power via the arm shaft. In most cases, its probably more efficient to bolt your sprockets directly to your arm then having to deal with large sprocket hubs, keyways, etc.
