Are Servos considered to be motors?
Hello. Our team is wondering if Tetrix Servos are considered to be "motors" for the purpose of amount of motor limits specific to the minibot supply rules.
Specifically, the minibot is allowed to have two motors (W739083). Could we use a Tetrix Servo in addition? Thanks for the clarification.

Re: Are Servos considered to be motors?
servos are servos
motors are motors they are not counted as the same hope that helps

Re: Are Servos considered to be motors?
Remember that there are only so many PWM outputs to signal spikes, jaguars, victors and servos. The cRio PWM outputs are a maximum of 750 mA, so you can only "Y" a limited number of servos to one PWM output. Research the cRio for this year, as well as the current draw of the servos you are using. This cocept would also apply to the Tetrix control system I would guess, but I have no definitive info on that system. Maybe someone else can help with the Tetrix control system.

Re: Are Servos considered to be motors?
IMO, you can use as many servos as you want, within the weight, volume, cost and system control limitations imposed in the rules.

Re: Are Servos considered to be motors?
Teched, they're asking about for the Minibot. The Tetrix normal control system is an NXT.
The answer: Are servos included in <R92>? No? Sorry, no servos allowed. Are Tetrix servos Tetrix motors of the particular model number? No? Sorry, no replacing a motor with a servo.

Re: Are Servos considered to be motors?
In Rule (92).A, there is a general statement that you can use Tetrix Components. There appears to be no limitation, and they have a 180 deg. and continuous rotation servo in the list of Tetrix components, along with a servo controller. It would seem to me those are allowable within the aforementioned constraints. Please correct me if, and why I am off base.
In addition, I commented on the Hostbot servos as I am sure some teams would be looking at this thread that want additional servo information.

Re: Are Servos considered to be motors?
The general statement on Tetrix components requires compliance with other rules. If Tetrix servos are more than 4W, they don't comply. <G19> specifies the motor(s) as being the source of vertical motion. As such, if a servo was used, it would not be able to provide any vertical motion.
I think this question should be sent to Q&A: "Are Tetrix servos included in <R92-A>, or are they in violation of some other rule?"

Why is there never enough time to do it right, but always enough time to do it again!
