2015: Mecanum or Slide?

[alephzer0]

For 2015, which would you choose?

[sanelss]

swerve. agility is ever more important the more confined you are and you have that bump to deal with

[Awesomegamer235]

i think slide because you need to be fast

[Cash4587]

Tank drive.

drop center allows for turning on the center of the robot for quick maneuverability i like that option

but with tall robots and heavy loads they will be very tippy

Going to ahead and say without proper motor management swerve might not be optimal. The standard swerve I see takes 2 cim's per module with 3 modules. That is using 6 cims.
Now if you don't use all 6 cims you would have in theory 3 spare cims. Thats a lot of motors for super structure.

Most swerve drives I've seen have four modules with 1 CIM each, although I have seen one offseason swerve drivetrain that used 3 modules.

Bomb Squad has used 3 modules for years.

Ether,

Are you suggesting this is a viable option for the game this year? Or just opening our eyes to other configurations that should be considered? (because you just opened mine...)

Because at first glance this looks easy to implement mechanically, not so sure if it is for programming, but you basically laid out the kinematics.

Plus there is no drivetrain arms race in the game this year, so traction and power aren't as important as it has been in the past.

No. Just tossing it out there to show that the "mecanum or slide" choice is a false dichotomy.

Personally, I would prefer a slide drive. It grants the most mobility at the least amount of complexity. It can be mechanically implemented similarly to a tank drive (save for the sideways mobility wheels), which is a style of drive train that Team 20 is accustomed to. Also, it still has more traction than mechanum, which may come in handy on the slick HDPE scoring zones.

Just my 2 cents

Why would slide necessarily be faster than mecanum?

In what way is slide less complex than mecanum?
