I have looked at several designs (including Mr McFeisty here) which have all been amazing, I even saw a few auto turrets😱.

Good things about this robot➡️ is that the gun is small, meaning it won’t dwarf (not a real one) the robot, yet it can still cover the range easily.

I have looked on countless websites (4) and I found a lot (really this time) of nerf guns, nerf gun parts and lots and lots of other guns.

I have showed them to dad, so that they can be scrutinised. Thankfully he already said that he likes a few (whew!).
