No idea if this would work, but I've wondered if it could be possible to build a big overhead horizontal like bloodsport but make the blade shaped a bit like an upside down airfoil to push the bot into the floor so it doesn't fly and flip so much when it hits something?
Not the one you were responding to, but here's my 3d printed blasters last time I photographed them all. Since then like three of them never got finished, and the Lynx got painted so it isn't black.
