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.
