We are going to be prototyping two drivetrains to decide which the drive team likes better. The first is the mecanum drivetrain, which exists and we are working on now. The other is omni-traction. In this setup, there are two pairs of wheels horizontally. The first pair is omni wheel
while the other are are traction wheels
The idea with omni-traction is that in a normal drivetrain with four traction wheels, when the robot turns it spins around the center and all the wheels lose tractions. With this setup, the rollers on the omni wheels allow the robot to turn and the traction wheels stay in place, meaning that it pivots on a horizontal line going through the traction wheels. This makes it easier to line up the robot without having to do something clunky like a 3 point turn.
For this, read through documentation and other things you may find online and try to decide what the best way to do this is.
