A general rule of thumb when building any robot is to maximize your offense as much as possible. Ah well, glad to see you've found the best weapon, drive, and wheel combination already so now it's a case of just improving and asking the more experienced builders for help.
BTW, Craaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaig, I told him as nicely as I could without praising him for bumping or actually, you know, being aggressive. It's not harsh, it's just looking for a problem where there is none.
Scorpion venom looks cool, however... What's up with the uneven weapons on some of the robots? also, those are hammers not popups, This is a popup - (https://gametechmods.com/uploads/images/30877Target Aquired In.jpg)
As you can see i used a T connector with extenders angled straight
1) (May want to shrink the chassis) Rotate the DDT on the left side, and make it even to improve wedgeyness, also rotate the right piston 1 tick left so its even with the other side.
2) Generic, but very well built , once again fix the hammer to a popup, and it will be good to go!
3) Looks cool, but get rid of the redbirds and lower the DDT's for better wedges. This should allow you to place more weapons evenly.
4) I see what you are trying to do, its cool, but flip the snappers over for better wedges, and try lowering it. (maybe replace redbirds with z-teks.)
5) Whoa, looks original, but i think iron spikes will fare better than samurai swords.
Overall, good job keep up the stock! :D
