Two mentors from 3824 tonight after running brutal cycles all day:
Craig: “Boy, I hope our bot stays together”
Lonnie: “I think there are about 8,000 mentors thinking the same thing tonight.”
First comment from one of our mentors was “well I better go start packing the toolbox”
We had to replace a length of chain after every match during Week Zero this weekend.
We’re planning on making the switch to #35 chain before our competitions.
A collective “We underestimated how strong to make the bot for Stronghold, wear and tear is ridiculous”
Five separate systems broke on first practice day…without defense being played
Followed by “We made a Jack of all trades again, we did not follow own lesson last year not to do it all just do one thing the best”
We can do it all hopefully…see if that works this year.
I’ll add “Need more practice , less engineering”
We might be doing back to back week 1 for sure and likely week 2…not sure if the bot will survive
Every step of the way this year I was thinking “we’re over-building this thing”. Now I’m thinking “We might just survive…”
Aside from our shooter forcing itself free of some shaft collars, we didn’t have any mechanical issues from a week 0 practice event.
I think the reliance on half inch hex shafts and bulky bearing supports might have been our saving factor. We haven’t snapped chain, nor have we bent any of our drive components. We’re also slamming over all the defenses at ~11fps.
I’m concerned about longevity of the smaller bits after six or seven matches. Retaining clips, E clips, and other small consumables tend to wear down, and the spring steel they’re made of just isn’t made for these types of force.
I can’t believe I let build season distract me from the fact that iHop had unlimited pancakes for a few weeks.
I’m glad I’m getting a cold today, instead of last week.
At the end of the first full day hard practice, we had 15 nuts and screws on the carpet…Now to find where they came from… We might just dip the entire bot in a Locktite bath before bagging.
LOL!! I’ve got a buddy mentoring a team with an 80/20 frame. I’ll pass on that advice. We thought of wrapping our robot in those big summo balloons and just bounce our way thru a competition.
What component will we break next?:eek:
I told my students that we should buy a case of blue threadlocker and sell it at the competition as a fundraiser. After reminding them to go over everything and threadlock it.
Last year, we saw how playing so many matches in the new IN district affected our robot in wear and tear. Now that we have a real Alliance vs. Alliance game with some rough defenses, I’m curious to see how District bots compare to Regional bots at Worlds. All I can say is if your robot doesn’t break something at a competition, you’re probably in the minority…
Thats what we said in 2014. Lets not.
Week zero made me very happy that we built a simple robot that could function even when things weren’t perfectly aligned… we almost used hex shaft to pivot our shooter and now I’m extremely happy that we used those flexible IGUS bearings.
Still running into issues with wires that weren’t secured properly, though… (that’s what we’ll be working on Monday and Tuesday, in addition to some driver practice).
I can’t wait to see the destruction. This year is gonna be fun on a bun!
We blew the 20A fuse on the PDP early morning yesterday at our week zero and fried a VRM due to bad wiring. (thankfully we fixed that issue) Other than that we didn’t encounter many mechanical/electrical issues.
Ouch. We killed a gyro when we plugged in our robot for the first time, but fortunately that’s been the worst for us so far… the main thing has been the cable to our right shooter motor, which got unplugged in two of the matches we played in Saturday.
I’m somewhat concerned that that’s been the worst of our issues so far, we must be missing something…
How expensive was the gyro you guys fried?
No idea. It was one of a few that have apparently been lying around for a few years. I’d guess around $30, so not too bad, but if we had to go out and buy another it would be dipping into a mentor because we’re just about flat broke right now.
