The basis of this is that you have a claw-gripper thing with rubber links that uses the vex claw linkage with intake rollers on the bottom that spin, up-righting the cone on contact. just throwing an idea out there
problem being that you’d need another power source for thoese motors, or a power take off, which would be inefficient at best
What if the cone is tipped towards you robot?
There are only two pictured here, but there would actually be four grippers, in a square shape
