Go to Post Anyways, before we all get worked up over this setup, let's wait and see what details emerge. It can't be as bad as everyone is making it seem. - Karthik [more]

Secondly, NalaTI is correct but remember you can only have 4 motor controllers, so at any one given point, the absolute MAX would be

4 12V Motors
12 Servos
3 LEGO Motors
-------
19 Servos/Motors

But don't think in terms of max, think in terms of functionality. If you need the 8 12V motors, then use those and don't use any servos.

Actually, you can double motors on the same controller, same with servos. Initially last year, they only gave us one motor controller and we had 4 motors - you could electrically connect 4 motors (2 per channel) to each of the controllers. You can only put one encoder into each channel, but you CAN have two motors.

So, strictly from a controller standpoint, you could actually have any of the following maximums

4 Motor Controllers (MC): 16 Motors + 3 LEGO = 19
4 Servo Controllers (SC): 48 Servos + 3 LEGO = 51
3 MC + 1 SC: 12 Motors + 12 Servos + 3 LEGO = 27
2 MC + 2 SC: 8 Motors + 24 Servos + 3 LEGO = 35
1 MC + 3 SC: 4 Motors + 36 Servos + 3 LEGO = 43

Since the rules limit you to 8 motors and 12 servos, and since practicality says that you won't double most of the motors, you could technically end up with:
2 Motor Controllers: 4 motors
1 Motor Controller: 4 motors (doubled)
1 Servo Controller: 12 servos (all doubled)
3 LEGO motors
Thus giving you the stated limit with still the possibility of some control.

All that aside... to re-iterate ttldomination's point "Don't think in terms of quantity, think in terms of quality." Use the right units for the right application and you'll have the best robot.
