Pre match switch for autonomous

[bladetech932]

we used this last year for lunacy we had the switch being the right wheel on the joystick
<30 = near starting
>30 and <70 = middle
>70 = far

Your joysticks work just fine in disabled

So it sounds as though there is a time before autonomous mode begins where you can set the throttle on the joystick without it being zeroed out, am i correct?

Where is there more details on the beginning, "disabled" time, and autonomous mode in the FRC Rules? I searched quite a while and could only find rule <G02> which just states that: "The AUTONOMOUS PERIOD is the 15-second period at the start of the MATCH. DRIVER control of the ROBOT is not permitted at this time. During this period, the ROBOTS may react only to sensor inputs and commands programmed into the onboard control system."

Any more details? Thanks much!

The period we're talking about isn't an official in-the-rules period of time. After you set your robot up on the field, get your driver station plugged in, and get it all powered up, you'll be running any code that you put in the "disabled" VI (if you're using labview. C++ and Java have equivalents).

This means that you'll have 30 seconds to a minute where everything is powered up and running when you can set your mode.

Okay, that makes our job much easier!

Thank you all very much!

We've been having a discussion in this thread regarding the various robot states and the modes that will be commanded during competitions.

There are a few assumptions in here that conflict a little with the thread over in the NI/Programming thread ...

Namely, the Joystick (and other) values from the drivers station are not "zeroed out" but rather, latched just before going into Autonomous Enabled.

Personally, I prefer putting the switches on the 'bot ... but there are many proponents of putting them at the DS so that they can perform "last minute" changes to their Auton strategy.

Okay i read the other post, and i think i understand a decent amount of it but i feel like i missed some of the concepts as well.

I am part of a rookie team and haven't had much experience so this is al a bit of a trial by fire.

When you say:

Namely, the Joystick (and other) values from the drivers station are not "zeroed out" but rather, latched just before going into Autonomous Enabled.

What exactly does that mean? And more practically, does that still allow me to, before the match starts and while setting up the DS, turn the throttle knob on the joystick, and then have it affect how the code runs when Auton begins?

From the dictionary: Electronics a circuit that retains whatever output state results from a momentary input signal until reset by another signal.

Loosely, it means to store the value in a place where it will be retained until you decide you no longer need it. And yes, it means you can set the throttle pre-match.
