A note on fishing line durability. I think this was mentioned in passing quite a few times but at some point, a mention of durability concerns becomes that final mention that makes you really start to question it more and so I finally did some research on chatgpt and found out a human finger...
Ok so I did a big refactor of my pulleys and ran a test again and it still is not working. The first set of archimedes pulleys tops out and can't move anymore while the finger still hasn't moved. This is because of slack in the lines. I did not calculate slack in the lines into my calculations...
Here's progress on a return spring for extension of the finger after pulley system has caused it to grasp.
Here's my completed V2 archimedes pulley system finally done! It is 16:1 downgearing and this pairs with my 2.77:1 downgearing on the turn in place pulley on the motor for a total of 44:1 downgearing.
Here's a turn in place 2.77:1 downgear pulley I setup right next to the motor output shaft.
and here it is in testing:
Here's my design for pulley based downgearing. Metal gears I think are too noisy so downgearing by way of pulleys seems best to me.
Here's the ribcage sculpt I did. I am making a fiberglass skeleton for one robot, using a pvc medical skeleton for a robot, and using a rod and hinge hollow steel tubing style design for another robot. I will compare each's pros and cons.
Here's the hand sewn together with spandex and adhesive transfer taped down in spots.
A handful of humanoids that are to pass for humans is the goal here and from there, these robots will keep making more robots exponentially for me. Then they can remodel homes or fix cars or anything I can think up. Gonna be fun if I can pull it off!
I'm focused on perfecting hand dexterity...
Hello,
Caution: Several MB of photos are attached.
Boilerplate notes: I have yet to workout a proper light box setup. As someone who's a student, in the vast majority of cases I've opted not to try and reverse engineer the items I teardown. Please bear in mind, although I can link directly to...
Much like anyone else, I've had my fair share of PC HW failure problems. The MotherBoard (MB), the CPU, the RAM, the PSU, etc.. But recently, I encountered a problem so bad that I felt I had to write about it.
But before we begin, I should tell you what HW I had. My PC was composed of a CPU, a...
Recently, I had the opportunity to electrically and thermally examine 4 wall ovens at no monetary expense to myself. Despite the fact that I couldn't do this under laboratory grade conditions, I none the less thought that my readers would enjoy a write up on the subject, so here goes.
There...
