Blueprint

Bob the Gun ( Automatic Turret )

An Automatic turret like the tf2's engineer. It tracks and shoot targets. Intended for riot control and other defense uses. Uses Pan/Tilt mechanism made by me for learning CAD. Has HMI so that I can learn software side and uses computer vision so that I can learn OpenCV and other stuff. Soon to add a ToF sensor for detecting distance to target for aiming purposes

Made the gun shoot further and fixed BUGSSSS!!!

  • Did some manual changes to the gears in the girl
  • Made some manual changes to the spring ( Reduced its stress )
  • Now the gun module shoots and it actually shoots pretty far ( 1.5-2x my room length )

( NOT UPDATED IN GITHUB YET )

  • Added a shooting manager ( It decides when to shoot, when to not, kinda inefficient tho )
  • Made changes to the shooting manager( Made it shoot while the gun was moving, not a good fix tho )
  • Fixed some bugs in the controller script ( The X and Y were both stopping if just Y reached its limit )

Made some changes for gun and software

Screenshot 2026-01-19 190342

[SOFTWARE]

  • Made changes to Controller
  • Made changes to HMI
  • Made changes to Arduino Code

[HARDWARE]

  • Made Longer Barrel for accuracy
  • Changed Sizes in Barrels and changed driving gear in gun to D-Type

[ FUTURE ]

  • Thinking of ditching this gun design as its taking too much motor load, might change to high RPM to Torque

[ HOURS DO NOT MATCH WITH HACKATIME AS I WAS DOING RESEARCH AND MORE OFFLINE MECHANICAL WORK AND WORKING ON OTHER DEVICE ]

Made some changes to hardware

[HARDWARE]

< Changes >

  • Made the gun’s driving gear to a D-Type shaft input to fix slippage.
  • Made the barrel longer to help with accuracy.
  • Fixed the push rod diameter to match with the newer barrel.

New Barrel

Worked on the HMI and fixed some controller bugs.

GUI 13-01-2026

Today, I worked on the HMI, fixing the "bad" variable names and some other functionality. I also fixed some small a bugs with the controller script.
Haven't pushed to repo yet as it is not 100% bug free.
