Re: Team 3675's 3 level climber!
 

Let me clear that up. The cylinder that is mounted to the frame pushes out the second cylinder and claw/motor assembly on a slide. After it reaches the end of its length, the PG71 motor and chain drive (Shown in the CAD drawings as a window motor and belt driven sprocket system) rotates to lift the second cylinder. We then move it against the rung, and close both cylinders. This moves us to the same position as shown in the 3rd photo of my first post. To climb the next level, we repeat the process with the other side assembly. We climb from the inside of the pyramid with our wheels perpendicular to the floor. Once we reach the top level, both pistons are retracted inward to contain us completely within the third climbing zone.

Hopefully that makes things a little more understandable.

Just looking at your design, i'm a little bit worried about the 54 inch diameter cylinder boundary that no robot appendage can violate. I know the the GDC changed the rules about this twice now and im not sure if you have been informed. The general rule is that the 54 inch cylinder includes the bumpers, and that the cylinder is only vertical relative to the field while not in contact with the pyramid. While in contact however, the cylinder is relative to the robot, with that being said, if you must violate the cylinder rule to climb while the robot is sitting flat, with the cylinder relative to the ground, then you also must violate the rule in order to be climb the pyramid. Just wanted to make sure that you were informed about this.

When the robot is in contect with the pyramid, it has to fit within a 54" x 84" cylinder in any orientation. The cylinder is not robot oriented. If the robot isn't in contact with the pyramid, then the cylinder is vertical.

While in contact with the PYRAMID, a ROBOT

may not have its horizontal dimensions exceed a 54 in. diameter vertical cylinder relative to the ROBOT and
may not extend any part of itself beyond a vertical plane defined by a perimeter offset from the base of the PYRAMID by 54 in., see Figure 3-5b and Figure 3-5c.

could you link to where it says it is in any orientation?

Re: Team 3675's 3 level climber!
 

The rules themselves have never been updated to state this and leaves the orientation somewhat ambiguous. It was stated in an FRC Blog Post.
