[Philip W.]

What fits perfectly snug on a tetra? Another tetra of course! Now give the tetra two levels of claws AND allow the claws to move freely in an up direction to easily accept a tetra but require pneumatic actuation to move in a down direction to individually drop two tetras and voila! You have team 188's tetra grabber designed by yours truly. Watch out Waterloo and South California regionals! Championships too once we get there!
