Disc bot bobbing

[Yeastisbeast]

I made this robot with big vertical discs(not huge though, 100cm). I tried with 2 DSL discs and the other black disc and (when they have 4 maces evenly spaced on) the first time I use them in the testing area thingy, they work fine, but the 2nd time the robot kinda hops and bobbles. Can this be fixed/prevented? Is it a glitch?

Maces are quite uneven so do tend to wobble. Or you might have AGOD, where the collision meshes mess up. Use F12 to check the meshes.

Thx ,it was the maces.

yup, the mace mesh is unbalanced. don't use maces for vs.
