Building a Lower-power Linear Actuator with Arduino | James Bruton

Building a Lower-power Linear Actuator with Arduino: quite a few people have asked me about scaling down openDog to make it lighter and cheaper, so I thought I'd discuss the options in this video. I'm using a motor with an encoder and an Arduino Uno to control position and velocity. You can get the CAD and code from: https://github.com/XRobots/Actuator_Linear My open source robot dog project. It includes everything from 3D printing to coding, including a lot of CNC cutting and installing all the electronics myself. If you want your very own four-legged friend to play fetch with and go on long walks then this is the perfect project for you. This way a dog can literally just be for Christmas. The full CAD is available at the link below for anyone that’s keen to build their own. https://github.com/XRobots Get your openDog T-shirts: https://teespring.com/stores/james-bruton ① 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, 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.

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. https://www.lulzbot.com/ Why not join my community, who are mostly made up of actual geniuses. There’s a Facebook group and everything: https://www.facebook.com/pg/xrobots.co.uk/community ② 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. ③ MUSIC AND SFX The majority of the music and SFX used in my videos is from Epidemic Sound http://share.epidemicsound.com/xrobots
