Team 935 autonomous testing

[railerobotics]

Just got our autonomous working after 3 snow days.

Now the snow can go away. Please and thank you.

Very nice.... I predict a good result for your team at its first event..

Cool but just out of curiosity how long was that. My computer did not show me.

It was 9.1 seconds across all of the tests based on the driver station counter.

Very nice! It's very impressive that you already have a fully-functional system that you've got a double-ball auto working on!

40 points right there...

[Animal Control]

Thanks and that was really cool.

I like how simple and fast your robot is, very impressive.

Are you worried about defending robots getting hit inside their frame perimeter by your collector mechanism, that looks like it must be deployed when you're shooting? Seems like you're approaching the edge of [G28].

The rule you are referencing (G28) does say that contact that is deliberate or damaging will be penalized. Excluding damage, there is a gray area of whether or not our contact was deliberate. Is the act of our robot shooting and a defense bot being struck deliberate contact on our part? We would be deliberately shooting the ball, not attempting to contact the defense bot. However I agree, that if we do cause damage we will probably be penalized, however the cylinders pushing out the arms are not forceful in any way. They only have the strength pull the arm in and out. They can be held up with merely an outstretched arm. Thus they will not be damaging unless we hit electronics (which is quite unlikely).

A lot of people have brought this up, but I doubt the penalty will be a factor for most teams. Getting your extensions damaged by hard hitting robots might be a problem but the penalty won't be called that often on pick up mechanisms. A lot of robots had drop down systems in 2012/2013 and their was a similar rule both years, I don't remember too many penalties being called, I remember a few cases where it should have been called but wasn't.

935, that is amazing that you already have a two ball auton working with over a week left in build season.

That's good that the mechanism is so forgiving, that should buy you a lot of latitude. I guess the only thing to really worry about is a defender stopping you from opening it in the first place!

Yeah I agree. That is what we are most concerned and we will probably build a couple spare loaders to swap in and out

And thanks for that, lots of hard work over the past 4.5 weeks.

Yup and only one solution for that.


Practice. Practice. Practice.

wow that's impressive.

We were also thinking of a 2 mode autonomous mode

Also, is that a Haas CNC machine in the back? Very nice

Yes it is, our team has been very fortunate in our high school partnering with a local community college. Because the community college has machining classes on our campus we are able to take full advantage of two CNC mills and two CNC lathes, as well as a multitude of manual machines. This also allows us to machine out every part of our robot, fixing mistakes as we progress through building it. And trust me, there are A LOT of mistakes. , but that is what robotics is about, learning how to fail, and learning from failing.
