Walk s super well . Hope to see more

[@outsider238]

I really love how smooth the legs walk. Looking forward to seeing what you do with the rest of it.

[@mrwoodandmrtin]

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.

[@Robothut]

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.

[@Rouverius]

Wow, walks like I do in the morning😅 Seriously, great movement

[@jayducharme]

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! Greg

[@Robothut]

Thanks Greg, could not have done it without your reversing screw files.

[@jobos98]

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. 😊

[@Zadakleader635IvanTheRobot]

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.

[@Robothut]

Yes I have already planned on keeping the reversing screw visible.

[@Zorua635]

If body was clear with an old style bulb inside to illuminate the inside man I would watch it walk for hours!

[@Robothut]

One day they may come up with a way to 3d print clear parts that really are clear.

[@rick_100]

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.

[@Robothut]

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.

[@rick_100]

@@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.

[@Robothut]

@@rick_100 Very cool. Keep us posted as you learn anything new about the A1.

[@Yuewaix]

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

[@Robothut]

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.

[@reg2590]

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?

[@Robothut]

Yes the moving eyes is possible and has been done in a few vintage robots. Good idea.

[@JGG1701]

How do i contact you for a robot questions and request ?

[@Robothut]

www.robothut.robotnut.com is my web site and it has contact email.

[@JGG1701]

@Robothut Thank you, sir.
