I was going to start a thread about upside-down discs, but remembered to search. Then I found this one. And decided to revive it.
Other than the teams mentioned, can you shoot discs upside down? Do you have a mechanism to flip them around/eject them?
My team can't shoot them upside down and doesn't have a way to get them out.
We can try flipping the robot to get them out, but it hasn't worked if my memory serves me correctly. (happens within the first minute of teleop)
Also, could you describe why it doesn't shoot correctly? Ours has something to do with the mechanism that pushes our discs into our wheel, it can't catch the edge of it properly.
