Re: I am very nervous
haha. I have no idea. also it seemed only to be a problem at low speeds, but it took me all comp to figure out why the speed seemed random. Again part of it was our design... a 2 cim drive direct through toughbox (1 cim per box). In the end this setup just sucks, sucks for programming, sucks for driving. We also found the setup would essentially overheat after a minute of use on the carpet, and would just quit. Hopefully other people can learn from our mistakes.

. I do not have the code with me, that also adds to my nervousness. And thanks for the heads up for the motors, I currently had it at around 40%. Man, our autonomy (actually software in general) usually gets scrapped until the end. We are the lowest priority apparently. Now I totally agree with you. Our sensors are literally going to be zip tied on or something. I constantly told the electronics, and CAD people what we needed from week one. It is not in any of the CADs. I can't believe everyone just expects the programmers to pull off miracles. So right now, we are like a blind man with a walking stick. It will be tough. Keep in mind, I have been programming everyday since day one. It is just that I had been given lots of little "projects" to do. I wanted autonomy to be #1 this year, but people kept on piling on jobs to be done and it was the last thing on the other people's minds. Last edited by davidthefat : 08-03-2011 at 21:27. |

Unfortunately, especially with FIRST giving out so much pre-written code (that only sort of works, not that anyone else understands that) people tend to assume the programmers job is point and click monkey. Matt |

Now, I am a very "low level" person and my mentor finds me too valuable of a programmer to be doing electronics or any hardware. I try to use the lowest to the hardware the software allows. I have just glanced over the pre-written codes, I was "appalled" by the thought of even copying the method of doing things they use. Plus, I don't like the way they do things anyway. May be that is my personality flaw, but I see it as a good thing. Might hint on the fact that I am arrogant, but shows I am independent. I have been criticized by other programmers because they think I am just making it harder on myself. I like the challenge actually and I feel guilty if I use prewritten code, feels like cheating to me. (Now it really is not cheating per se, but feels very much like it) |

To that end, working on the electronics and mechanical team is very very good for programmers, and even if your case I think you'd find it a lot easier to work at a higher level when you're solving more interesting problems. Instead of "they finally mounted the pot, now let me make it work" you can approach the problem as "I need to control the arm, here's what I have to work with". Plus, I'm getting really sick of the stereotype that programmers with power tools are dangerous! Help me change it.Matt |

Re: I am very nervous
My honest recommendation is to sign up to be the "Team Scapegoat". Everything is the Scapegoat's fault, so the Scapegoat always gets blamed.
Of course, it is NEVER EVER the Scapegoat's fault. So, you can rest easy knowing it was not your fault. But only as the Scapegoat. == Seriously: Test your code in the practice sessions, that's what they're for. At the very worst, you disable it for the entire regional - not the end of the world. |

Practice sessions are useful, and don't be afraid to ask other teams for help. At the same time, if you absolutely can't figure out your code problems, turn the robot back to the mechanical team and let them make all the tweaks they're inevitably going to want to make. Go take a walk and see if you can help another team with their programming problem! Believe it or not I've had many Eurekas while helping other teams, and its great networking for you and your team.

Re: I am very nervous
My only advice: Turn your nervousness into confidence. Be excited about the competition. This is my first year in FRC, and I am stoked for the SVR! We may not have the best robot, and we may not win, but out of what I've seen and the previous competitions I've watched, it's a fun and life-changing experience that shouldn't be ruined by nervousness. Go and have fun!

Remember that this year wasn't wasted, you will learn what to expect. I have a whole list of design requirements for me to implement in the off season, and I'm sure you'll have the same after comp. I'm actually planning on building my own chassis in the off season, to play around with some of the things i'd like to implement. Have fun and make the most of comp. It's a good time if you don't take it too seriously ![]() Last edited by mwtidd : 08-03-2011 at 22:41. |

Dont let yourself get down if you arent experienced enough to use the sensors, or your mechanical guys decided they werent important enough to put on the robot. Success will come as you gain more experience. |

My kids got a state machine together to run through the sequence of aligning the arm and driving up to the goal, and it was working but hard to keep perfectly aligned with the goal. Then we remembered the photosensors on the front and of the robot and were able to write a line tracking algorithm that just braked the wheel corresponding to the sensor that was tripped and we were in business. Compared to some of the autonomous challenges we've gotten before, this wasn't too bad. Not to say it was easy, but it's certainly doable at an event. |
