Hrmm, Sorry about the pun 
How Fast does your Bot Get to the Top ?
Our Bot is a beast ( atleast we hope so ) its gettin up just over 3 seconds ( like 3.2-3.4 area ) thats about as fast as it will get
still not exactly sure what we will do with the rest of our time, prob. just try to run into stuff
Dan Team #710
To get from the start position to the top of the HDPE (hit the stacks) takes ~ 2 seconds easily.
wow I’d like to see the drive train on that one
do you have any pictures posted?

Lets try to keep this thread to accurate numbers. I highly doubt you make it in 2.0 - 2.9 seconds, let alone easilly.
Our robot makes it to the top in 6 seconds in low gear (about 4 fps). We are working to reduce that number into the high 3 second region by running in high gear (about 10 fps). The shifting method is still being worked on; luckilly school tomorrow has been cancelled.

Well until competition can you disprove them? just take it for what it is worth to you, and in a few weeks everyone is going to know about most everyone else.
We ran our bot in autonomus mode tonite and
got to the top in around 4 sec’s. Our program is still
a bit raw but we’re definitely going fast!
One team at the SCRRF scrimmage had an arm that came out and hit the boxes. Took about 2 secs. Unfortunately, we did not get to see our linetracker yet because their tape was not reflective enough.
look at he gallery. We have pictures showing were are robot is and how long it took to get there. we hit the top in 4 seconds and the other side in 7 seconds
Regarding the fast times… are you using line sensors or dead reckoning… if your using line I am highly impressed, if you are relying on dead reckoning I would re think your autonomous strategy.
Whats wrong with dead-reackoning?

remember, if your a line tracker, and someone pushes you off, you’re just as screwed as if you’re a dead reckoner and someone pushes you.
I would have to disagree with that, if you line track and you get pushed off, your bot will look for the line and continue its path.
Oh and if you think I am talking about robots in the way thats not what i meant.
I might want to relay to you that depending on the shape of the front of the robot, It may not be as easy as you think to knock them off track. Enough said…
We use dead-reackoning.
we use this because it is the fastest way we know to get the job done.
I would like to see someone hit us before we are on the ramp.
If they can hit us in 2 sec for the start then my hat is off to you.
but if you look at our arms, if we are turn off our route the arms will center the robot when it hits a wall and then it will be a pushing match.
I hope you program your robot to shut off because If we are in a pushing match I bet we will see white smoke coming up for the robots.
I really think a lot of robot will be dead in the water after the 15 second auto time is up.
because the robot is not doing what you program it to do and it kills itself.
your scare the robot is in danger so you hit the stop button and you have to wait another 30 seconds.
you run into another robot and you get flipped over. ( this one I see happening a lot this year for all those stacker’s.)
Last thing there are going to be teams that are not going to be ready so their robot will not even move.
This is slightly off-topic…
but if you look at our arms, if we are turn off our route the arms will center the robot when it hits a wall and then it will be a pushing match.
We looked into the possibility of adding an arm when we ran the forces. It would require us to attach to the field in some way to keep the robot from falling over. This would of course violate the playing field rules. How do you stay stable?
i also find the possibility of 2 seconds VERY VERY improbable…
you’d have to be moving at a speed greater than 12 FPS even while turning.
i can see maybe an arm reaching up and hitting them or something of that nature, but a bot running up the ramp that fast is very unlikely.
we get up there in about 5 seconds. yes i know that’s a pretty slow time, but we’re not about the speed.

the last time i checked, our bot was doing 15 fps on carpeted surfaces. that goes down to about 10 on rounded turns. we make it up the ramp (to the boxes) in just under 3 seconds. i love our drive train. oh, and by the way, thats in low gear.

I agree… We call it autonomous suicide…
I expect to see quite a few robots damage themselves, perhaps even terminally during autonomous rounds…
As for your comment about white smoke pouring out…
Shouldn’t a properly designed low gear spin the tires when at “static push”. If done correctly a robot can push against a wall for 2 minutes, and still not over stress the drivetrain.
I know that’s how I designed ours.

We made our if it hits the wall we will push the wall down. We make sure we have more traction than not.
We saw last year people that had good traction get flipped over because of there traction and were they grab the goals.
And we saw robots burn up there motors.
So I would say you will See at lease 4 robots in each of the regionals burn out there motors and that is on the low side
We hit the boxes in 7 seconds at the best.
How fast are your times with totes stacked in front of the ramp or all your times with a clear shot? It makes a difference to our bot.
