Re: Sheet Metal vs Tube Drivetrain

When using sheet metal I don't think it's a matter of "choosing" this building style based on what is best for the game but designing the robot to meet the needs of the game with bends in the right places/using thicker material. Many teams were successful with sheet metal this year as well as tube.
I think SystemS was specifically talking about circular tubing-- in which case what they are saying is extremely true. It doesn't really apply too much to the discussion of drive trains, but it is definitely applicable in that context. I haven't had a ton of experience with using circular tubing on FRC robots, but there have been some cool robots who have used it in the past (I think 118's elevator in 2015 used circular tubing).
