I've previously built several robot dogs which used a variety of servos and brushless motors. The most agile robot dogs are the ones with back-drivable low-ratio reducers which allows the motor to be back-driven so we get some natural spring in the legs - which can be controlled on the fly with software. So it's time for openDog V3 - this version uses my Cycloidal Drives which I've developed over the last few months. I will eventually publish the CAD and code as open source when it works.

@TheTsunamijuan 2 года назад
If weight wise the bearings are still to heavy, consider trying UHMW rod. UHMW has a great natural lubricity to it. As long as your not putting UHMW against itself it slides wonderfully. Which would be a considerable weight savings. I would say that nylon didn't work as well partly due to the fact you had one solid rod interfacing with both the upper and lower drive, which are moving opposite each other.
@joe7272
@joe7272 2 года назад
If you use UHMW naturally it would be possible to replace those labor intensive metal rods with larger, printed fitting alternatives right?
@TheTsunamijuan
@TheTsunamijuan 2 года назад
@@joe7272 i am not sure tbh, i have only used it in small applications for its lubricity. where the material thickness is thinner to begin with. In these applications till will compress and deform. But that is not considered a problem. as it returns to original shape unless marred by something. I now i tend to favor metals for shafts as opposed to printed ones, partly due to the lack of layer line weaknesses and dimensional stability.

@dujezarkovic2384
@dujezarkovic2384 2 года назад
That's the thing with just about any and all hobbyist electronics projects. Nothing ever gets finished. The problem is that the sky is the limit when designing stuff like this. You're not making a product to be sold, so there is no point where you have to say "good enough". You can keep modding it and improving it, and although the process is really fun, at the end of the day you're left with expensive, complicated, unfinished toys. It's the reason I stopped playing around with Arduinos and Raspberry Pi.

Super cool work man. I will say though it looks like your prints could use a little tweaking. Visually the first layer needs a bit more extrusion and then maybe adjust your layer settings. Or adding a enclosure around your printers will help with layer adhesion. The stringy-ness and rough sides is a dead giveaway that they aren't performing as well as they could be.

If you're worried about the top of the legs jamming into the carbon fiber tubes, you might consider redesigning the black pieces at the top of the legs to have a curved profile. That way, if the leg hits the bar, the leg can still move fore/aft without jamming.
