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.

Update: It's taking me a shite tonne of time to figure out the logic and coding for the esp32 devices. Chatgpt is not a good coder, fyi. It's good for a simple set of instructions, but once it goes down the wrong road, it just collapses to gibberish, lol. Searching and reading/watching tutorials...

Oh, and I want to exchange the bulky nano/joysticks/buttons to the esp32 with a little tft touch screen. Then I can add or subtract buttons and controls. If I can figure out the code for them Well I think it's great you are keeping a great analog tech alive for future generations. Yeah, I have...

I'm revamping the control modules. The first versions are too big and heavy, so I'm moving from Arduino and big old motor drivers to esp32 modules. Much lighter, more powerful, the esp32 has all the items to create a control system with wifi, Bluetooth, lotsa ram and processing power. Also...

I had a limit switch on each leg, that would supposedly stop one leg, then fire the other until it hits it's limit switch. It can go frontwards, backward, and "steer" by slowing the cycle on one side. The problem here, is the limit switches were not reliably triggered. So, I now have a hall...

Here is a little preview of the mechanism:
