Successful crossing, and you found the new low bar!
Although I wonder why that red robot decided to keep driving/shooting after multiple calls of "stop the robots".

PVC field. That explains a lot.

Guys, come on, this is totally legal. They're just using the new secret passageway as noted by Team Update 9001.
It only stopped when we estopped it. We looked at the code it never would have stopped till it hit a a wall or got out of range. Needless to say i think we need to work on our auto.:ahh: ::ouch:: :cool:

Atleast there wasn't a spybot.

Just a question, do the refs or the field managers not have an option to shut down all the bots? Or did everyone just forget about it in the heat of the moment?

They couldn't get FMS Lite to work, so everyone was self-starting their robots using the Driver Station's practice mode to simulate match timings.
The real FMS does have an option to E-stop all robots.

At the Week zero event we went to, the FMS wasn't working well(different laptops were controlling different robots) so everyone just configured the normal way and did the "practice mode".
EDIT: Too slow to answer....
FMS Lite can E-stop a robot. However, as we found out on Saturday, if it's in a test match, you can't clear the E-stop! Easier to pull the Ethernet cable.

Speaking from experience here... Your worst fear should be breaking the robot, not this. If your robot runs into a wall for 15 seconds, it's no big deal. If you cripple your robot for 90 percent of a competition, that is a huge deal.

I am amazed that nobody was hit!:eek: That human player in yellow is part ninja.
And then everyone else starts the match like nothing happened at all.

We're extremely happy that nobody was injured and that we can laugh at it now. As someone else noted, we were having issues with our FMS/new radios/driver stations that caused us to revert to using Practice Mode. The potential for injury is our biggest fear running an event like this and not having a full field stop makes that risk higher.
Later on in the day, there is a robot that completely destroys the low bar. Unfortunately we didn't get video of that. Our wood field has stood up to 15 years of abuse running 3 events a year, and after this event it is in by far the toughest shape I've seen it. Curious to see how the real field stands up to the abuse from all of the robots.

I have to agree here. We were extremely lucky that nothing broke.

It was just trying to escape :)
Did the reset crew throw the bot back in? :D
For anyone with labview,
If you press space bar when the robot is enabled, you will trigger the emergency disable. If I recall the only way out of that afterwards is to reboot the robot.
Just a little tip if you get to practice with your bot.

Yep. we just disabled auto and played a normal match.
The robot was simply proving that with modern technology robots can, and are eager to, take over the world (https://what-if.xkcd.com/5/).
Luckily real FRC fields likely would hold up to this, and if the robot did leave the arena for some reason, the team and field E-stops would stop it fast.
With that said, the GIF of this will never get old.

That is something that has seriously been concerning me. What if a robot causes a field element to be damaged beyond repair in the middle of a regional?

Thanks for the compliment :cool: I was the Human player you're referring to :cool:

I Think the spy bot would have been mostly out of the way.

I hope they bring extra defenses :p

The robot actually showed literally no signs of having hit anything after the match, the bumpers weren't even discolored. Thankfully our robot was thoughtful enough to use the door in its escape :p
We're very confident in the robustness of our custom drive-train and custom welded roll-cage.
There was actually a robot at the event that just ran into the castle wall every single match for auto.....
I think robustness is going to be a big issue for a lot of teams this year.

I think you might just be right since the robot was making a bee-line for the hallway leading back to its friends in the pits.....

Events will have 3 full sets of defenses. One set is for the practice field, and is designated as the spares for the competition field in the unlikely event that a defense is damaged past functioning.

I would be careful using the word unlikely. Someone crashing full force into things like the cheval de frise could take it out.

The thing is, the official parts are designed to a higher quality than what we've seen in shops and Week 0 events. I think it will be unlikely.
Even if it happens, the spare and replacement practices FIRST uses should prevent problems.
Plus, don't forget FIRST engineering will have presences at some early events to monitor things. If precedent holds, they'll quickly work to address any problems that arise and roll them out to the fields on the road.

Your robot has officially become Juggernaut from X-men.
I would be careful using the word unlikely. Someone crashing full force into things like the cheval de frise could take it out.
After working with the official FIRST defenses....I'll stick with my term, unlikely. Dealing with them brought to mind the mentality of "belt and suspenders". They are heavy (Field Reset is going to earn their Volunteer Food this year) and extremely well built. My wife would probably bring out the term, over-engineered, which I would agree with but very much needed in an FRC field due to exactly what you brought up.
Unlikely also does not mean never. However, FIRST does not want to have to ship out replacements especially since they would have to be extreme rushed to get to the next stop for that field (read: EXPENSIVE) so it was in their best interest to make sure these things will perform at least as specified.

Is that something new? Most Regionals I've been to in the last 10 years did not have a full practice field, let alone full-spec field elements. Usually a nearby team just brings a set of team-spec elements.

yes.

This still won't be a full practice field. For the most part the practice field will be the same size, scope, and quality of previous year's practice fields. Just the defenses will be full field spec, but only one set of them, instead of the two the main field will have.

Most regionals (I can't speak for district events) should have at least one set of field elements. For example, in 2012 there would just be the four hoops and one bridge, in 2013 the goals and one pyramid, etc. Definitely not a full practice field, though...

Also the same for Java.

In addition to what others have already said, there will also be one base for the defenses to sit in, not a full complement, so there will have to be swapping out to test on each one. The tower will be of the wooden variety but the defenses are the same ones that you will play on the real field with. They are the spares for the real field so they are just being put to use instead of sitting in storage for the event.

Replying to myself because it looks like FIRST has some work to do on the Cheval de Frise (the most vulnerable to physical damage). In the first 9 matches in Palmetto, 3 times this one has been disabled (and now taken out of the mix while they are figuring out a plan). I wish the stream was better than 280p so that I could see what was actually happening to them.
This is one reason why a Week 0.5 was considered a good thing. There are lots of FIRST people onsite and at HQ to work the problem.
