We’ve all been there — you see somebody do something cool on YouTube and you just have to give it a go. For [lonesoulsurfer], the drop-everything-and-build happened to be a little four-legged walker robot that runs on a single servo. Though it may be simple, there really is nothing like seeing a robot you created take its first steps.
[lonesoulsurfer]’s walker is made mostly from scrap aluminium and other scavenged parts like coat hangers, paper clips and the metal bits and bobs from banana jacks. The Dremeled and bent body would likely be the hardest to imitate for a first-time builder, but any sturdy chassis that allows for things screwed and bolted to it should work. Also, don’t expect it to work right away. It will take a bit of tuning to get the gait right, but it’s all part of the fun. So is modifying a 180° servo for continuous rotation.
We really like the way this robot walks — it saunters around like a long bulldog and looks like it can handle almost any terrain. Watch it walk after the break, and stick around for the build video.
There’s just something about simple robots without microcontrollers. If you’ve never heard of BEAM robots, cut your teeth on this ‘bot with circular legs.
(watching the video of it moving)
It reminds me of the crawling zombie once featured on HackADay.
This one…

Walking is when each foot, once set on the ground, remains mostly in one place until lifted again. This is crawling.
TIL I crawl upright on two feet.
Maybe you shuffle?
Since when we call single servo funbots robots idk
Technically, it’s not even a servo anymore. It’s a dc motor with reduction gearbox. But it’s moving and has a humanoid shape, I’d call it a robot.
So a doll rolling down a hill is a robot? Catagorization is hard, kins of why coconuts seemingly fit some loose definitions of mammal.
Tarantula spiders v. mammal
Has hair, gives live birth
Pedants and haters unite! This seems to be the post for you today. Just a shame you can’t all be rounded up and mass-ignored.
Personally I enjoyed the video and like the project. Creating something from scratch from coat hangers and other scrap appeals to me.
I agree with your last sentence.
That is hackaday’s commenter crowd in a nutshell. It has been for years. Every article is met with comments about how bad the design is, and how wrong the designer is. Constructive criticism is great, but the audience here isn’t constructive about it. They just come across as the Simpson’s Comic Book Guy.
Looks like some stick bugs. Creep me out

I really like the clever and simple build
