So, double catapults. Ours is being dumb. We had it working correctly three days ago at the end of a competition. Now, the problem we’re having is that our catapult has mysteriously stopped hitting the middle flag. One ball still hits the high flag, but the other sails between the middle and low flags, sometimes toggling the low. Does anyone have suggestions on what might be causing this change, or how we could fix it?
Did you change anything on your robot that would change the height of the catapult? Also, take a slow motion video of the catapult shooting two balls at once and look at it to make sure they are both leaving the catapult properly. One thing our team noticed is that if the balls were not completely settled in the catapult before firing, it messed up the shot completely. If you could post a picture we may be able to help you better.
Yes, we are shooting from the same spot. We took a slow motion video, and while the top ball goes straight for the high flag and hits, the low never reaches the height of the middle flag. We are making sure the balls are settled before firing, and we haven’t changed anything since it was last working.
Double check support structures and make sure nothing got loose and moved a tiny bit? We had a sudden arm alignment issue and it turned out a support had moved a tiny, visually unnoticeable amount. It wasn’t wiggly loose but just off enough to cause an issue.
Verify no misc screws or nuts loose or randomly added? Check any shafts for twisting?
We had this same problem when the standoff that sat behind the ball was slightly out of place, which messed up the shot by a couple inches. Make sure the backplate that the ball is against is tight where you want it to be.
