Wiring Question
Hello i'm Phuc from team 4229. We are using actuators this year and ran into a problem of sorts with getting the actuators to run at the same speed. Does anyone know if it is against the rules to hook up two motors to the same jaguar or talon? I tried looking through the rule book but couldn't find anything about this. Thanks.

Re: Wiring Question
See rule R42 and Table 4-4 in the Game Manual.
It depends on the type of motor. If you are using PWM, you can use a splitter cable to send the same signal to two motor controllers. If you are using CAN, you can set one motor controller to follow the other. |

Re: Wiring Question
Be sure to check that the amperage that the motors would pull does not exceed the potential output of the jags.

Re: Wiring Question
The problem is more likely that the actuators are responding differently to the same input; if this is the case, putting both of them on the same controller wouldn't help. If you really need the two actuators to move in sync, there are two basic solutions:

The list of controllers is R41 (A), and includes both talon, R41(A)(B); and jag, R41(A)(A). Last edited by GeeTwo : 09-02-2015 at 10:35. Reason: fix rule references |

Just use 2 talons/jaguars/victors but connect them with one spit pwm cable.

Re: Wiring Question
And what are we supposed to assume if our motor doesn't fall into one of those categories? Why doesn't FIRST simply state current or power limitations?

The only motors and actuators permitted on 2015 FRC ROBOTS include the following... If it isn't in the list, you aren't allowed to use it at all. |

Re: Wiring Question
the motor on that actuator looks a lot like a CIM. If you can take a legal CIM and stick it on that actuator you are back in action.
The restriction is on the motors we can use not what they are connected to. |

Is your team going to be at one of the week-0 scrimmages this weekend? If you let me know which one, I can try to stop by to help at some point and make sure it's legal! |

Re: Wiring Question
Great! Do what you can to make sure it's legal and functional this week, I'll stop by there on my way down to Simley and look for you guys between 8 and 8:30 Saturday morning. Get there nice and early!
