Time to Knock Down 10pt in Auto

[ngreen]

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.

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 :^)

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.

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.

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.

Out of those who are knocking the 10pt ball of how many are knocking the ball out of play?

I'm not sure how fast ours can nock it off, but it's not slow. We're using the IR sensors, and we get it under 10 I believe. And that's only because we need to line up the arm with the ball. At the Upstate scrimmage we went to, 343 (Metal-In-Motion), had a great auton mode that worked really really quickly. I'm not sure what they used though.

Yes, we only have the capability to knock it out of play.

Out of play I think. We could hit it in if we wanted but, nah.

Around 3.2-3.5 sec at our home practice field. Never really tried in comp. We dont want to endanger the arm so we use a piece of fiberglass. It wacks the balls out of play, but who cares about those things anyway? The 10 pts in not worth the effort.

All I can say for sure is that it can be done in 2 sec or less. If you are at a reigonal with the KillerBees (team 33) you'll see it. If you want to know how, look for the recent thread on transmissions. A 4 speed autoshifter, combined with a straight line auto mode, and the balls are on the field before the starting music is finished.

As to why, there are many strategies that depend on ball control, and if you can get there first you get the control.

Is that 24 feet from start. Meaning one wheel over the line

On a direct route it is 23.88 feet from the wall to the ball tee. You are starting around 3 feet in front of that with a 36" robot. Your arm poker that is in front of you covers the other .88 feet so you only have to travel 20 feet. If your top speed is 15 ft/sec I imagine in a direct route you could manage to knock the ball off in around two seconds. There might be one sub two (1.9999 sec) and several near two (2.0-2.2) but I imagine it will be few in number. Less than ten definitely less than twenty. In the 1 to 2 percentile. I see more of the better autonomous mode being in the three to four range so that they don't just ram the ball off. Maybe someone can grab it in less than five or someone will do multiple task like knock that ball of and grab the 2x with 10 seconds.
