I still haven't quite figured out how that setup can turn, and already I want to cry. I'm fearing that in a major way.

Question Swerve drive?

Some how I have a strong feeling that this is a version of swerve drive. Think about it, why would they want to use three drills just to turn the wheels? The three drills are used to turn the wheels with the help of beval gears, so there could be something else that rotate the wheel box. So, all 4 wheels will spin the same speed, while some other motor steer the robot.

After all, this is just a sneak peak. The robot is probably more than just this.

Uh... those motors don't look like they just turn the wheels! Take a closer look at the third picture. It looks like they have two gears perpindicular to eachother to transmit the force to the shaft the wheel is on. The picture is somewhat dark, so you might want to turn the contrast up.

...Or am I totally off...?

I am not sure why you would want all of the motors to have the same wheel speed if you needed to change the orintation of the robot. We are swerving this year with all 4 wheels interlocked but we also need to tank steer to get the orintation changed and that requires different speeds on left and right. I am not sure what the sneak peak is showing us at this point.

the front and rear wheels turn via 2 steering motors, so the front can turn independantly of the rear.

The robot is programmed to interpret wheel posistion via the X and Y on the joystick, so if u want to slide to the right, you move the joystick right, and the wheels will turn, and the robot will slide sideways, and vice versa, we can slide in any position. Pots give the robot controller information on the front and rear wheel posistion. for high speed work we have car mode, where the joystick will turn the front wheels depending on the position of the handle. If we get into a jam we have panic mode, where two knobs allow us to change the front and rear wheel position. a 3 poistion know allows us to change in between the modes, so we have 3 driving modes, depending on the drivers preference.
