2) Your robot entered into a 'stable' and 'predictable' orientation in Zone 1 (locked) before going into Zone 2.
Some of the ideas our team considered did not have a stable locked configuration in level 1 before continuing toward level 2. All that is needed is to be above the ground and in zone 1 before contacting zone 2, but I did not see anything requiring you to enter a static state before continuing. It is possible to configure your center of gravity such that lifting off the ground initiates a reach for level 2. As long as you are off the ground and do not contact it again after contacting level 2 I think it would be a legal climb. This dynamic shift in position is driven solely on how the level 1 lift point was positioned with respect to center of gravity. It can work fairly easily for a level 1 to level 2 reach. But it is hard to make it work for a level 3 reach.

This is not the design our team went with, but there are some designs that will work for level 2 and yet cannot easily be extended to level 3. Even just the fact that the bars are getting closer together in zone 3 may limit the height of some climbs.
