While straight line speed and chicanes are kinda of conflicting, I understand the premise of increasing difficulty and appreciate it :-).
Will the curvatures of the wall be symmetrical or asymmetrical? Since the white line is down the middle can it be assumed that minimum clearance between white line and wall will be >= 225/2 (half of the max width of the robot)? Otherwise it becomes more of a navigate/wiggle your way through the chicanes with the white line as just a way to center back.
The rules state 64mm on each side for the chicanes.
Does that mean a 2×3 set sideways as shown in the drawing?
Do the chicanes go or not go to the top of the 64mm walls?
Are the chicanes painted a pastel purple like the picture?
Are the angles on the ends of the chicanes 45 degrees?
Best I can tell the chicanes look to be 3 feet long. Is this correct?
