-While they may not affect your ability to go on the bridge, the ability to stay without being pushed off or falling off of the bridge tips your direction will be tough to deal with
-You won't be driving circles around other's bots unless you have a lot of practice.
-In order to work to their fullest extent, require a lot of thorough engineering
-More complicated to code, even at the minimum level


Like I said, I'm not telling you not to use them, but when you do, be careful and engineer it through (Not meant to sound like most interesting man in the world meme, though I'm tempted. )
  • We've been using Mecanums for the past three years and have found no huge loss of traction
  • Usually, but this depends on the drivetrain.
  • Definitely; Mecanums are a lot heavier than conventional wheels.
  • I think most teams use 4 CIMs to drive anyway because it gives the robot a ton of power.
  • Mecanums powered by Toughboxes don't get pushed around as much as people think, but it's defeinitely soemthing to consider.
  • Agreed, a lot of practice is needed with Mecanums to be extremely good at them.
  • Not a lot of engineering, it's really only the initial one-time assembly that matters in the long run.
  • Actually, my team uses all of 20 characters for our Mecanum code, not counting the button to turn it on

Just my experiences with Mecanums.
