Our design is much the same except without the simplicity. Actually to say it is much the same is wrong. It uses the same general principle, but it has like eight other mechanisms built in. It was inspired by a design by a different student on our team, which was inspired by another of my designs which was inspired by the arm prototype demonstrated on episode one of "American Robot".
I think we will be seeing a lot of designs that are all very similar. The problem I am now seeing with a design like this one is that when the robot is carrying the tetra its center of gravity will be way out in front of the robot unless they have a way to allow them to flip the arm behind the robot without dropping the tetra.

Edit: How many teeth do those sprockets for your arm have? When I did the calculations for a similar setup for us it would have been 4.5:1 reduction which would barely have given us enough torque to lift a tetra at the end of a five foot (and it can extend to seven foot) arm.
