Why is high capacity Mecanum wheels important to the movement of this robot?
Mecanum wheels allow savvy robot designers to create drivetrains capable of moving in any direction using a standard chassis shape. Simply power each wheel with a different motor and change the directions the wheels spin to get your robot to move in different directions!
Are casters wheels?
A caster does indeed include a wheel. But, it is more than a wheel. It is an assembly that contains both a wheel and a bracket for it, sometimes called a “fork,” or “yoke” And this bracket that contains it is what separates it from the regular wheel.

What is crab drive?
Crab Drive is basically a swerve drive but instead of each wheel being rotated by a separate power source, they are all rotated together. The advantage is that its holonomic and has traction wheels, but the down side is that you don’t get the flexibility of movement that you would with a swerve drive.
