Familiar...yep! This is the third year we decided to use a 2-link arm. We really debated the pro's and con's of a 2-link vs. a single pivot with telescope vs. a lift. In the end we chose to go with what we already had experience with.

We made a decision in week 1, that a 6wd would work better for us in transiting the field, as we expect some pushing contests in the middle. This 'bot is so responsive, that we have not had alignment issues when hanging tubes. While I have liked the holonomic and swerve chassis's we've built, 6wd has won me over.

We avoid wrapping the tubing, by raising the shoulder counter-clockwise ( in this view), when we reach for the top pegs. For the middle peg we raise it clockwise, but not much above 45deg. So far the tubing has not shown signs of fatigue.
