I'm thinking about that also...I have a lot of nail gun blanks at home...still looking for the correct way to convert it to 22lr. maybe I have to make the pellet/projectile mould using 3d printer? see...I'm noob...:(
It's too big...๐ฌ
Yes, I mean now I'm more interested in more general UGV that can carry any kind of payload on it, like cameras, robotic arm, and guns etc....and I've found more suitable design ..the name is Freefly Tero. I'm sure you are already saw the videos of it circulating on the net, video of this Tero carrying a gatling gun ...

But I still want to finish the project I've started ...so maybe I will make two UGVs; one Dogo and one Tero...:D
Some weeks ago I've printed the top part of the DOGO (the gun holder box), I just curious to see the size of it and interestingly it is perfectly fit to my Elegoo Centauri Carbon print bed..
I want to use the printed part to design the gun holder /clamp and the trigger mechanism using my G26 toy gun, but cant finish it because I have to go to other city for my job...so now it's postponed.

yes..I'm modifying a ready off the shelf drone,DJI Inspire 1.you can google its max payload..around 3400 grams.there are some videos on YT about people testing its lifting capability.the challenge are how to mount the gun and how to design the recoil compensator...I have to make a completely new frame design for it,so I can attach/swap many kind of payload underneath its belly..i.e aerial mapping camera(s), net gun for catching drone, or gun,etc...actually my main purpose is using this old drone to carry heavy sensor for earth exploration,while carrying gun is just for fun/experiment. Anyway,is there any design of recoilless gun here? :D
At the same time...currently I'm building drones that can shoot...like the drones in Ghost Recon video games...made by "Skell Technologies" ...seems like it use glock also.. https://80.lv/articles/designing-drones-for-ghost-recon-breakpoint
Pixhawk is a flight controller,people usually use it for DIY drones. We can configure it using Mission Planner software (free),there are some options ..what you want it to be...multicopter drone,plane, or rover...and APM is the predecessor of pixhawk.
You know the price? How much is it? I think my design plan will not be the same with DOGO, more like a tank/tracked wheel vehicle with pan/tilt head....I will grab some RC tank design from thingiverse and then modify them...so it is not a "replica"...:D
I plan to use APM/Pixhawk for this...I have some of those boards laying around collecting dust.what do you think?
you can download its 3d model from rigmodels.com btw...

yess...Yeehaw...๐
This one has pan and tilt feature...that is what I'm looking for... Then I have to make modifications...make everything bigger;,...bigger motor,maybe 360 degree servo on the head...and so on
