There are some great advantages over a six bar v.s. a four bar that we have noticed. here they are…
Looks a little too easy, and unpredictable
Easier to hang with
and lastly, require less parts.
We spent a long long time perfected the height on our 4-bar and we are not prepared to reveal this to anyone yet,but will release a series of videos after Worlds explaining our Robot’s.

4252A did not have a 4-bar. We had a 6 bar. The design of our 6-bar served several purposes during the design we first used it for which are not necessarily applicable to our design at state. I really don’t think either a 4-bar or 6-bar are going to have a serious performance advantage if either are built well. A 6-bar will be a little bit heavier/complex (and only a little bit), and can be more finicky stability-wise but will get you more height more easily with more configuration options. 4-bar will be easier in some fronts but will be trickier to get greater height with.
