Building a Robot Dog (with an airsoft gun)

Blog post about my mechanical design, robot math, stress testing, and competition for "Mech Warfare", a small airsoft-only battlebots competition this summer
gertlex•3mo ago
OP getting this robot working in about 3 months was insanely impressive.

- guy whose back yard the scrimmages took place in

oidar•3mo ago
what is the no gimmicks rule?
gertlex•3mo ago
I can't quote it offhand, but it's stuff like:

- Don't stick your camera on an arm and poke it around corners to see the opponent

- No detachable parts? It's more nuanced than this. Not leaving "mines" I think is a case of this.

Basically there's a few goals to the rules (this has been an on and off competition for about 15 years now): keep the spirit of "pilots in giant mech robots" (loosely 90s era stuff), and homogenize the competition slightly for competitiveness.

Melee is still allowed! If you walk into the other robot and trigger one of their 4 score panels, that still counts.

It's a hard competition to prep for. Numerous bespoke HW subsystems, software, budgets that grow quickly with the size/weight of your bot... and being reliable.

Excellent write-up. This is one of those side projects that has been on my list since forever and this seems about the level of accomplishment and tech that is within reach. Good effort! I'm looking forward to further refinements.

Thanks!

That happened.

I absolutely hate this. Great to the OP for amazing work, but I am so sad that we're living Black Mirror dog world instead of Star Trek equality world.

There needs to be a new word for when you're impressed, but so depressed at what is being achieved.

flemhans•3mo ago
Any plans to release the files or a build guide?
eschluntz•3mo ago
Yeah if there's more interest I can publish the GH and onshape! I just need to sanity check that I didn't leave any keys in it or anything...
gertlex•3mo ago
Having had a chance to read more of the blog now, maybe the most pleasing part is your similar discovery of, "I'm writing my own kinematics, and generating plots of it is the fastest validation of that code". I did similar matplotlib plots of my quad (spider) leg movements years ago. Definitely need to do more of that when I finally revisit the software on my mech from 2019 with AI help :).

And more generally, yeah, having the AI manage some of those plotting needs will be fantastic in other work too; I enjoy figuring out what to plot, and don't mind wrangling and hand-refactoring said scripts... but it's so time consuming historically, and there's always the itch to urgency to get back to the "main code". (at least I learned to gradually convince peers that often plot scripts should be commitable without being polished; they're a form of documentation sometimes!)
