Stronghold Drivetrain Review

[jwfoss]

Our redesigned chassis held up very well, it consisted of the following:
-8WD with .160 drop centers
-6061 2x1x.125 Tubing except for over wheel rail mounts (1.5x1x.125 Tubing)
-WCP SS 6CIM Gearbox modified for #35 chain, non-direct drive, and spacers to solid aluminum/solid delrin with 1/4-20s
-WCP Bearing blocks with 1/2" Round Bearings
-4140 1/2" steel hex stock turned round through bearings, keyed for sprockets
-6" Pneumatic WCP hubs with diamond tread
-#35 Chain running on 12T sprockets
-Full Wrap Belly Pan

Built it once, only maintenance was checking tire pressure.
It's safe to say that our first time with our modified WCD was a success and the teams new baseline.

Can confirm, 558's drivetrain was good this year

As a rookie team we went with the KOP chassis with 6wd 8" pneumatic wheel upgrade kit. A lot of teams had some crazy complex drivetrains, but I'm really proud of our simple design, which must have been one of the lighter designs. We never got stuck on any defenses, and we could cross at almost full speed with the tires absorbing most of the impact of landing. As a driver, sometimes I wished we had some kind of transmission to have more power for pushing other robots and accelerating quicker, but I can't complain. I always was surprised when I saw teams with tons of experience and complex drivetrains getting hung up on the ramparts or moat.

100% agree. We modified our AM14U3 to have gear shifting and 8" pneumatic wheels. The gear shifting was totally pointless, but our drive train was able to go over all the terrain defenses, as well as outmanuever any defensive bots that tried to stop us. The one downside we had was that our drivetrain was very wide, making it difficult to line up with the defenses (particularly the freaking sally door).

We got to einstein with that drive train so I would say it has an amazing complexity to effectiveness ratio.
