Remember when Lucky took a hit from Beta’s hammer and knocked its flipper in creating that “cobra stance”? Check out the full fight Here. Well this happens when the rear section of a 4-bar flipper rotates too far forward.
The happened to my bot during testing. The rear part doesn’t want to rotate that far mechanically, but the inertia from the arm going up causes it to rotate a bit further than expected and then bend back into place.
This should be an easy fix of adding a brace to prevent it from physically rotating that far.
