While I'm waiting for openDog parts to arrive, I decided to build a test rig to experiment with a robot leg that has an elastic tendon. I can make the leg comply with force, or drive force between the motor and the actual leg position.

② GENIUS

No MacArthur grant yet. But while I’m still waiting by the phone for that call, maybe you might patronise me with your Patreon-age or pick up some of my merchandise. Or, if you’re all out of digital cash just comment on one of my hilarious Instagram pics, pop me a Tweet or generally yell in my direction.

Huge thanks to my patrons, without whom my standard of living would drastically decline. Like, inside out-Farm Foods bag decline. Plus a very special shoutout to Aleph Objects, Inc who keep me in LulzBot 3D printers and support me via Patreon.

③ 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.

④ MUSIC AND SFX

The majority of the music and SFX used in my videos is from Epidemic Sound http://share.epidemicsound.com/xrobots
