Actually, it's not much harder than any other FIRST bot unless you decide to machine your own omniwheels. The toughest part is independently powering all 4 wheels, but some teams do this anyway on their 4-wheel drive bots.

Sorry for being ignorant, but what exactly is a holonomic drive?

technically, a holonomic drive is a drive that allows you to move in three axis at once (i.e., going forward, left, and rotating). examples of a holonomic drive are 857's kiwi drive (killough platform) or the technocats ball drive.

a swerve drive is not truely holonomic, but for FIRST robot purposes it is close enough. a swerve drive has the wheels rotating seperately from the robot orientation.
