Tue, true. I even made some single 18650 battery holders so I could put those on each leg near the feet as well. This thing has been such a huge timesuck, I may have to pick up another project for a couple of weeks then come back with a fresh perspective. I have been frying electronics, faiing...

I have added a gear reducer to maybe help me get the needed torque vs weight battle. This also gives me the ability to have two cams instead of one. I found adjusting the shape and offsetting lengths I can fake a better step motion curve to to be flat on bottom and lift the foot forward and up...

I do like these solutions, but I am trying to fit the whole shebang into the foot shape and have some up and down motion as well as back and forth.

Here is my controller scheme, and a shot with him in costume.

Oh, I really like this design. I must admit though, I am shooting for a look more than realistic biped walking. I was majorly inspired by RobotHut's designs from thingiverse and youtube. He made a "peg walker" version that looked really cool. Thanks for the pic though, that is a very cool...

Is there a picture or diagram of what you are describing? I can't quite see what you are proposing. :)

Thanks guys! I got the control board pcb and hooked it up. I went a head and made an offset wheel instead of the linkages. Also, I used some slightly larger stepper motors which, even though not that much bigger, proved to be much more powerful. So now, I'll try to put the linkage based foot...

Almost.....:fireguy:

Well, speaking of time and brain power, I always seem to be in short supply of one or the other, lol. After many more mistakes and odd rabbit holes I meandered through, I'm back at it. The N20s are great, but the ones I have just can't crank out enough torque to over come the friction of the...

Here is the page with the files and instructions Just fyi

Much Progress! I think I've proven to myself it's going to work, so I moved over to making the legs and frame for the larger version. I moved to steppers instead of dc motors to get more torque and holding power. I have all the components of the system working together and running on battery...

Absolutely! My favorite design, for sure. I also am enamored by these hexapod walking mechanisms. They're basically just two DC motors and some gears but it'll go anywhere and is really cool and simple.

Ok, I finally got the video made, lol. I'm currently porting the remote over to an esp32 with a small touch screen. No more clanky buttons :)

I hear ya man. I spent the first 30 years of work in mines and factories. I know what drives them and the goals they have and don't care to be a part of that ever again. I tried for years to learn code, but it always took time away from the art side of creativity. Probably a mistake, but it's...

Thanks! I need all the help I can get :) I'm also checking out some of these visual block coding apps too. There several of them out there, most are free or have a free version as well.
