Vex motors

How many moto’s can you have on a robot in round up. I know there are 8 inputs but what if you used y-cables to make room for other motors:D

Your answer is in the VEX Round Up Manual on Page 18 (PDF Page 20)

<R11> Robots may use up to ten (10) VEX EDR motors or VEX Servos (Any combination, up to ten)
a. Of these ten (10) allowed motors, teams may use a maximum of four (4) “2-Wire Motor 393”
modules.
b. 2-Wire Motors must be controlled by a 2-Wire Motor Port, either directly on a VEX
Microcontroller, or on a “VEX Motor Controller 29” module.
c. Teams may NOT use multiple 2-wire Motor Ports, 3-wire PWM Motor Ports, or Motor Controller
29 modules on a single motor.

<R12> A maximum of one (1) VEX Y-cable can be used per Motor Port of the Microcontroller or Power
Expander. (You cannot “Y off a Y” to have more than two (2) motors controlled by the same Motor Port.)
a. Teams using the Cortex Microcontroller can only power one (1) 2-wire Motor per each of the
two 2-wire motor ports on the Microcontroller. It is illegal to “Y” off a 2-wire Motor Port.

Also don’t confuse the Inputs with the Motor Ports, they are separate Ports.
