It's time to build the ultimate robot dog using the R&D from my previous builds. This dog will use Quasi-Direct Drive from large diameter low KV brushless motors so that we can make the joints dynamically compliant using the same method as my previous back-drivable test dogs which worked well. I'll then add the some of the dynamics I tested in the miniDog series.

This video is a recap of the previous R&D, a look at some motors, and also the process for laying out the mechanics in CAD.

XROBOTS

Former toy designer, current YouTube maker and general robotics, electrical and mechanical engineer, I’m a fan of doing it yourself and innovation by trial and error. My channel is where I share some of my useful and not-so-useful inventions, designs and maker advice. Iron Man is my go-to cosplay, and 3D printing can solve most issues - broken bolts, missing parts, world hunger, you name it.

XRobots is the community around my content where you can get in touch, share tips and advice, and more build FAQs, schematics and designs are also available.
