Well, I only watched the webcasts, but here's my best shot at this.

Launchers with a "roller gripper" to pick up balls were shining. Teams like 1114 fit into this cataglory.

The 80in rule wasn't called (at all) from what i saw. Even tipped robots didnt get checked/called. Impeding wasn't called either.

High scores were 130+. (I think MWR QFs). Lowest ones were 10ish without penalties


More important than how you hurdle, though, is accuracy. I saw a lot of shooters nail the overpass and fail. I've also seen arms ram the overpass and fall >.>

We found that regardless of how you hurdle it is important to do it without stopping or if you do stop only for a second.

Line violations, Line violations, and more Line violations
Watch those lines, thats the most popular penalty to be called.

A good Hybrid is important to winning...

i've been watching on blue alliance; the lifts are extremely slow. The arms are too tip heavy and the lauchers are doing well. The hybrid is extremely important and most teams are not doing it.

also the thefro526 is right. On the vids there are a lot of lane violations

Three things are important in this game
Speed
Speed
and
Speed


Fast bots for laps and hybrid.

Cycle time to acquire ball, move ball, and hurdle, doesn't matter if you lift shoot or a combo of both, the need to do that cycle quickly is what separates the bots.


80" rule was called in St. Louis, line penalties were big, hurdling interference was called a lot on Saturday, impeding not as much. Also extension outside the box contact was called a lot more on Saturday.

[thefro526]

Also go to your local craft store and buy LOTS AND LOTS of velcro, teams are shooting down full speed in hybrid/auto and one of our teammates today got their control board broken. Use the hook end of the velcro to keep your board secure and be ready to catch the board should it fall.

Use your coach/robocoach as extra eyes, there is a reflection off the lane divider that can cause confusion.

And once again watch those line penalties!!!

Wow. Thanks for the pics, my team did not tell me this.

Beware the flags/lap counters. They are IR transmitters! Our autonomous failed miserably until we relocated the flag holder, then it worked 100%. Thanks again team 25 for diagnosing this problem, and helping with the repair.

The plates on the center dividers are an issue. Even with over 3/4" ground clearance, our bot was hung up on the carpet once. (it must have been loose or pulled up)

Bots with forks - Be aware of the fencing material in front of the robo-coach. We had to modify the forks 1st day.

that exact reason is why i accidentally knocked over 2022 twice during a practice match after 1114 did it in hybrid they kept putting it back up.
its also an effect not noticeable from the stands which i got crap for driving weird down there. lookout drivers.

[thefro526]

As said by Dad1279 you should place something on the end of your forks so that they cannot go the the fence on the robocoach station, we found that tennis balls work great and that you can get colored one's from a teacher/classroom supply place.
