MRB1 (My Robot Buddy V1) Project

LOL. I understand the anxiety that goes along with trying something new. When I was designing my B9 robot arms I had no idea if I could make them work the way I wanted. No one had ever been able to make a robotic B9 arm move like the movie robot's arm did. 3D printing was still an experment and all I had to work with was metal. I had no idea how to make it happen but I wanted to try. I think I went through 5 designs with several different motors before I found one design that worked close enough to what I wanted. Lots of money spent and lots of left over parts but it was a blast learning and somewhat frustrating at the same time. Afterword's I lined up all the failed designs and took some pictures. I called it my "Hall Of Shame". LOL!!

Dave,  the "Hall Of Shame" that's a good one I have a box of shame that's full of bad prints and mistakes in my designs.   What's killing me right now is I have the new parts printed but I can't bring myself to go sit in my hot garage right now and put stuff together.  It's like working in a sunna.  The other bad thing I find myself dreaming about this stupid arm design...  I need to bite the bullet and get-er done!!  But not today.

Again, I understand. LOL. I'm right there with you . Living here in Florida makes it hard to do anything outside in the summer other then float in the pool with a cold adult beverage.

Agreed!!!  you are so right about that.

it good to use your brain when its to hot .  have some water and some rest is golden .

Nomad 6R,  I love Willie LOL.  Maybe today I will try to get down there again and make an attempt at putting it all together.

Well here is my new InMoov arm design almost done with 5 of the six joints done and put together. I have to wait for my servos for the new InMoov V2 hand to come in so I can add the rest of the forearm, wrist and hand to it. I have the J6 wrist joint done just not added to the arm yet. I wanted to make a video but until I can’t until I get the arm mounted because I can’t hold the arm, camera and work the arm to demo it so your stuck with pictures at this point.  I can tell you it seems to work very well and seems to be less noisy the the standard arm. I still need to work out the cable management but I need to get it mounted on the on the torso to complete figuring that part out.  Spent time tonight working on the hand because I needed to make changes to that to support the new wrist joint.
