I really love how smooth the legs walk. Looking forward to seeing what you do with the rest of it.
Walk s super well . Hope to see more
If you put a pin in the top of that worm axis you can turn something in the head.
like the overall feel of the body design.
That is a good idea. The top of the Worm has a double d cut out so connecting a drive to it would be easy.
Wow, walks like I do in the morning😅
Seriously, great movement
I’m in agreement - great walker! I’m surprised Japanese manufacturers back in the ‘50s and ‘60s didn’t use a worm gear like that. Seems like it would have been simple and reliable.
Very well done John, I knew you'd do a fantastic job!

Thanks Greg, could not have done it without your reversing screw files.
Being that the grooves are at a 45 degree slope, you probably didn't need supports there, but definitely on the tops of the change of direction & around the lower points at the intersections.
I've learned that things on a 45 usually don't need support...
In general. 😊
Looks like it walks really well. The ratchet mechanisms work smooth. Looking forward to see what the extra function will be. These faster printers are great. I now have an A1 that I'm using on my Vincent project.
Have you done any speed and quality tests on both the A1 and the A1 mini. just interested to know if the A1 is as good as the Mini.
@@Robothut I haven't done any real testing but I started using it as soon as I assembled it. I only did one small print of the battery doors to test it. Then I printed the middle part of the Vincent body that's too large for the mini. It's the largest part I've ever printed. It took almost 9 hours . Ninety minutes of that was printing supports. The quality seems comparable to the Mini. I've printed a couple of other big parts also.
I'm working now on the Vincent so I sliced the bottom of the body in Bambu Studio. That's the part the legs attach to in the video I did on it. For the A1 Mini the total time was 5 hours 58 minutes. For the A1 it was 6 hours 9 minutes. So pretty close. So far I'm very pleased. I got the printer without the AMS. I have the AMS that came with the Mini if I need it.
@@rick_100 Very cool. Keep us posted as you learn anything new about the A1.
If body was clear with an old style bulb inside to illuminate the inside man I would watch it walk for hours!
One day they may come up with a way to 3d print clear parts that really are clear.
Would be nice if you kept the chest with an opening to see the worm in action. Maybe painting the slot would make a nice effect when running.
Yes I have already planned on keeping the reversing screw visible.
you could do like 2 piston-looking cylinders on the front of the robot that movie in and out tied to the leg movement, could almost look like a visible engine on the front or something
Great minds think alike. Yes, That was one of my first thoughts, might still go that way. Kind of want to come up with something I have not done before.
I like your idea for the body i.e. having a number drum clicking round.
Is it possible to have a head with a drum inside having 'eyes' turning first right then left, perhaps like a cylon but mechanical?
Yes the moving eyes is possible and has been done in a few vintage robots. Good idea.
How do i contact you for a robot questions and request ?

Thank you, sir.
