That is an incredible idea for picking up tetra’s. A sphere, thats cool. The tetra is going to balance itself and its not too difficult to get out from underneath it. I wish I would have thought of that.
Good luck at the regionals/nat’s.
Great Idea, as an avid Lacrosse Player I can’t belive i didn’t think of that! G/L To your team!
P.S. THey Make Lacrosse balls in blue, just thought it’d match your robot better.
