Dealing with robotics regrets

[anonymous_robot]

I would say that it is safe to say that everyone has had something they were not proud of performance wise occur in relation to robotics. For me it is flawed designs that I did not push back hard enough to get the design that would have worked. To me things like that are haunting and really cause me to be ashamed of my work. I am sure that I am not the only person who has had issues with something they wish they could have done better. So my question is how do deal with the regrets you have around robotics?

[DonRotolo]

Same as regrets in life: Learn from them.

This is called "growth".

[artdutra04]

There are three main mantras:

1. Nobody is perfect.

2. Don't make the same mistake twice.

3. Life is iterative.

We're all human, we all make mistakes. How you deal with mistakes and problems, is what really elevates successful people, robotics teams, organizations, etc above the rest.

Whenever you finish any major project, you should always sit back and reflect upon what you did good, and what could be done better. Be honest with yourself - if something was terrible, come to accept it. Don't blame other people/events/etc! It's way too easy to fall into a trap that "if only X random event didn't occur, we would have won!", when you should be working on making yourself/your team immune to X random event.

I personally tend to follow the "Toyota philosophy" that initial mistakes are the result of bad process - not necessarily bad people. Analyze what went wrong and what could have prevented it, then take action on implementing new ideas/processes to prevent the mistake from occurring again.

For a long time, the "what went wrong" will all likely revolve around lack of experience. The only cure for this is to keep getting back on the horse when you get kicked off. The more you practice, the more you do, the more you reflect on what you're doing, the better you get. It will take years and years (it has been referred to as the "10,000 hours of deliberate practice"), but one day you'll look back and realize that you're no longer making all those mistakes that you once were.

The usual robot related stuff like over valuing the ability to cap an existing six stack with an RC that made our robot a jack of all trades and master of none.

While I was mentoring a team I really regret losing focus on what this is all about. Having a competitive spirit is good and winning can lead to inspiration on its own, but that competitive side can really put a damper on the ability to work with students. There's a thread that usually comes around every once and a while about mentoring fresh out of high school. If you decide to take that road (and let's keep that discussion in those threads), really ask yourself and more experienced mentors/adults around you, "How can I be a better mentor for the students?" I wish I did.

Regardless. Learn and move on. You can never take something back or go back in time. Consider how you can prevent it from happening moving forward and remember those mistakes when you come across similar circumstances.

[Ryan Dognaux]

Learn from your mistakes and move forward. That's what I try to do every year.

I've made questionable calls as a drive coach that I still think about. I'll never forget telling our 2014 drive team to go for another high goal shot when a low goal would have secured the match and turned the St. Louis regional rankings upside down (Link: http://www.thebluealliance.com/match/2014mosl_qm80 Sorry 1658 & 2408) I've watched that match video more times than I'd like to admit.

As many have said, you get better through experience. FRC isn't easy. The fact that you are worried about what you did wrong is actually a great thing. It means you want to improve - now the trick is figuring out how to do that. Focusing on one or two things each year is a good way to start, depending on your team size. If you get a little better each year soon enough your team will be great.

I think one of the harder parts about FRC and improving is that many of us use build season as a metric for improvement. This becomes a problem because buildseason is only once a year and so you don't get the instant feedback that people like to have.

A very similar thing happened with our team this year, so I know just how you feel. A lot of my teammates let this bog them down for the rest of the season, but ultimately, that wasn't going to help us out either. We had to accept that we had no control over the design situation and make the most out of what we had whether we liked it or not. Even though our design this year was very limiting on what we could do on the field, we worked hard to perfect the performance and look of that design, which resulted in us winning a couple of design awards. Even in failure you can still find success, you just have to make the most of the situation.

I deal with it by coming back and building an even better robot the next build season.

Biggest regret of 2015; Not having the cardboard box at the SF regional.

I must be old, because the elevators I regret are from 2008, 2010, and 2011. 2015 is me (as a mentor) learning from those 3 high school years.

That brings up a good point about regrets. It's very easy to overly generalize a regret. The fact that you regret your team's elevator says very little about the quality of elevators as a concept. There have been many great elevators before, and many great elevators will come after. Instead of swearing off elevators forever, and potentially overlooking them in a situation where they'd be a great idea, why don't you try to figure out what specific details of your elevator you regret? Even then, it's very unlikely that the correct answer is as simple as "part X is bad." More likely, a good answer is along the lines of "part X shouldn't be used in combination with motor power Y if we aren't also able to completely prevent the elevator from relying on hard stops."

In engineering, good regrets are usually very specific.

My biggest personal regret regarding robotics was the team's second year, and my first year (2013 Ultimate Ascent). I was mechanical mentor for our secondary function (that is, climb); my experience with antisubmarine warfare through the 90's and 00's (and before and since) set me up to work around another "more important" function. "Team Foundation" (drive and Frisbee thrower, herein referred to as TF) had built what they felt was a good device to accelerate and spin a Frisbee (and it was great after a few more tweaks). They had not yet figured out how to lift a Frisbee from "the stack" at the bottom of the ramp into the first spinning pneumatic wheel. I verbally pitched a pneumatically-powered "finger" that would push from inside the lowest Frisbee. No one got the idea, and everyone else's idea was much more complex, so I decided to take things literally into my own hands. I walked around the build space, "cutting" aluminum bar through metal fatigue, doing a bit of rough hand bending, and bungeed a working prototype lifter into place on the build frame before the discussion died down. Once people saw it work, it took little time before it was "plan A". TF put in metal bars to mount the cylinder, but they did not replace the metal-fatigue-cut finger. I tried to convince TF that the finger was a prototype that needed to be done right, but they resisted the idea and I GAVE UP TOO QUICKLY.
Fast forward to Bayou: By now, we were putting 95+% of our shots taken from our sweet spot (essentially under the pyramid) into the 3 point (highest) goal. Once we worked out how to load from the station (which was built well outside of specification), we were a real competitor - when nothing went wrong! We had matches where we forgot to close the manual pressure relief valve, and it seemed like everything that could be set wrong was set wrong in at least one match. Despite our extreme case of TRS (twitchy robot syndrome), we managed to rank #20 (to this day, the only time we've ranked in the top 24). We were not selected for playoffs, and might have declined if we had been, because we were not ready to compete. It seems that our jury-rigged pneumatic "lift finger" had jammed beyond any easy repair. Shannon (another mentor), I, and a couple of students worked in the pits for about an hour trying to fix the lifter mechanism. After playoffs had run through a full cycle and we were nowhere near finishing, we called off the repair and started loading the trailer. It was literally well over a year (summer 2014) before we revived the Frisbee launcher. These days, our "no mentor prototypes on the competition robot" rule would have ensured replacement by a student-built part, but I've also learned to be more assertive in fixing problems in general.

This is a particular case of the general rule given several times above: don't forget, learn.

I feel you... We had a very nice full court shooter that adjusted itself automatically but no way of feeding the frisbees because our climbing system took too much place... so yeah we did shoot in auto then we would only climb because that took us more than a minute

My 2007 robot on 1678, decided to go with a 5ft 110lb robot with a huge ramp. Ramp was too big and had a hard time fitting in the end zone, got many penalties. Should have made a 4ft 120lb bot with a steeper ramp incline so we could fit easy in the zone.

It did manage to go from about 8 ft square as a robot to 45 ft square as a mobile ramp. Had to carefully budget the weight for paint on it >_>

The robot was taken apart long ago except for the ramp skeleton which had the urethane hinges rot away from the elements last year and was finally torn apart. Nobody wanted to drill out 3000 pop rivets or cut the urethane apart(tougher than nails I tell you) Made a great support for our old shipping crate to keep it off the ground and getting a bad case of dry rot.

May you rest in pieces Parking Citation/Origami Go-Kart.
