Name of arm that moves in vertical plane?
Hey everyone,

Does anyone know of an arm device that rotates on a single point, yet unlike a four-bar mechanism, the end of the arm will stay in the same vertical plane? I know a vex team did this in 2010 with picking up the inner tubes and I thought the device was really cool. I can sort of visualize how it works, but all I remember was there was a sort of "scissor lift" mechanism on the end.

Thanks
