Time to Knock Down 10pt in Auto

[Yan Wang]

For all the teams who are trying to knock off the 10pt ball during autonomous and for all the teams that have succeeded in doing so... how long does it take?

[nerdcool64]

I would like to know the same thing. My team didn't have enough time to test the IR sensors, I have always been wondering if they work and how well.

[Elgin Clock]

~4.16 seconds...
Thats of course if all works well like it did at the test facility!

I heard that the fastest time so far was about 2 seconds.

IMHO, it dosn't matter. Unlike last year where to the top of the ramp ment points, I think speed to 10pt ball is useless. Life will not be easier if you get ther first or last.

Speed will be important to some strategies. Especially since the balls contol when the other balls drop I can see being able to control at least your side will be important. I'd have to as to see how fast ours was but I know it will be around 5 seconds as a rough estimate. That's being conservative though.

[Elgin Clock]

But... getting thier faster does leave you time to do other things or get in position for the drivers to take over. That's the plan!!

thats not entirly true; if you are a ball collector and someone knocks your ball off before you get into posting that could ruin your whole stratagy

Yar, our team got auto working the night before ship around 9:30pm... It took 10.5 seconds (after 3 trials). This was due to a little programming bug (robot turns around 360 in opposite direction instead of turning quickly towards the ball and was not at full speed in code). It should be down to < 7 seconds by regional since that'll be fixed. Regardless, speed doesn't seem very important.

Hmm, If i had to guess, the fastest time we will see will be around 3 seconds. Maybe we will see high 2 seconds, MAYBE. But I seriously doubt it.

I figure that it is about 30 feet from the wall to the ball, if a fast robot travels at about 10 feet/second, we're looking at about 3 secs.

We max out at about 8-9 ft/sec so it would take us about 3.5 secs to knock the ball off.

Everything depends on the form of sensing, line trackers will take the longest at about 10-15 secs, IR tracking will be about 8-12 seconds, inertial guidance will take about 4-6 secs (depending on the skill of the programmers) that will be followed by dead reckoning and encoder based systems which I will predict will be the fastest. This is all of course dependant on the skillz of the programmers and the hardware design.

I would guess, that depending on practice and skill, encoder and inertial systems will be tied for the fastest systems. Combinations of those systems will also be in contention for the fastest.

If that is our autanamous stratagy...

Good Luck!!!

The ball is <24 feet. There are several robots that can go 15ft/sec +. So I expect to see several 2 seconds and possibly even a sub 2.

[KenWittlief]

2 seconds would really be impressive

not only being able to move that fast from a dead stop

but being able to track the ball position while moving that fast, stay on course

and detect precisely when to trigger whatever it is that knocks the ball off.

Sounds like a good basis for an unoffical team sponsored award - fastest time to release ball - the silver bullet award :^)

[Yan Wang]

So how fast does your team do it, Ken?

our carpet was a little short to have the right size on the field, so we never got an official time test

we will be there around 5 seconds - we are using the stock sprocket trannys this year - not real fast, but they do what we want.

[henryBsick]

As my good alumnist cliff put it, "we get there in 3.7 seconds only because we have to slow down to turn." From what you are all saying, it is pretty quick I guess.

[sanddrag]

About 3 seconds for us. Our carpet was slightely rougher than the FIRST carpet though and we will have to adjust the program a little.
