What do you think??? (I did it... but is in spanish.. ahha sorry )

If you came up with a version that could be cut on a laser cutter, I could get them done for you

Google's sketch-up software is free and pretty awesome i hear

Bret,

I like your design. Hey the majority of my drawings are hand drawn.

What are the lengths of the aluminum bars?

So the plastic disks turn freely within the PVC and provide support? Correct?

How are you mounting the servos to the aluminum?

Have you tested the operation yet?

Yeah, the plastic disks are 1/16" smaller than the ID of the PVC so they turn very freely. They provide the support for the arm. As I am doing a small B9, the length of my arms is only about 7 inches so my bars are not that long. The one coming out of the PVC is 4 inches long and the other two pieces are 2 inches each. I am just going to use epoxy and zip ties to attach the servo bodys to the bars, then an aluminum servo horn and screws to attach the shaft. I am going to use all metal gear servos.

I have not tested operation yet, got sidelined with my motorcontroller issues, but hope to get back to the arms soon.

What a wonderful idea!!!

I want to do some sort of arm. There's been a few posts etc about them I was given this link for a hand.

Here is the buster post to see it in action.

I wasn't sure how to make it smaller but still usable. So I decided to hack a robosapien for his arms.

@edison2- Have you started to build this arm yet? Do you have pictures?

@DJ Sures - I have heard of Google's sketch-up but have not tried it yet. Will have to look into it... That's a cool offer about the laser cutter. Have you had pieces / parts cut for your robots? Are the prices reasonable?

@sfoy - How's Minion coming along? That's a cool idea to use robosapien arms. Can the hands actually move and grip things? Do the elbows have servos?
