Here's the problem with the minibot

[PayneTrain]

Not to mention FTC teams are more restricted in their rules than we were. Here is a list of things on the most successful minibots that come in a Tetrix kit:

2 Tetrix Motors (with detached gearboxes)
1 Battery
1 or 2 switches
And they use wiring, so I'll include that.

What we made:
3 pieces of beautifully cut channel aluminum
Custom Axles with surgical tubing
Anderson PowerPole Connectors

Not typical FTC materials, but we used them because we could. The point of the minibot was never explicitly stated, so its purpose may have died before ship day, or even before the infamous Team Updates.
