Hi,

We are from team 3089.

We are currently debating whether the following mechanical structure of the chassis and bumper is legal. The chassis is divided to two parts that are joined together allowing it to change its geometrical shape (as shown in the pictures) when going over the bumps (articulating chassis). Above the lower chassis, is a chassis of a larger perimeter that has a solid structure and will consist of the bumpers. As stated in rule <R11> the chassis itself does not change it's shape and when the robot moves on the flat surface it is parallel to the ground.
But when the robot will go over the Bumps, the chassis changes it's angle compared to the ground and the robot.
Regarding rule <R07> A, the upper chassis is designed so that the bumper will not go out of the bumper zone, and won't move or deform while on flat ground.

Thanks, every comment is useful!
