Re: covering...
Quote:
we dont have any skins or covering over our robot, but all of our electronics are in a sealed box in the heart of the base. A few wires are visable, and two potentiometers... but theres enough chain going around everything that i think a tetra would get stuck in that first before it hit us where it hurts... In past years we've had a lower base or there were balls that could easily bounce anywhere, but the tetras are so much bigger we arn't worried about them getting into the small hard to reach places. |

Re: covering...
I do not believe that this had come up yet, but I'm pretty sure that if you check out the indpection list (posted on the USFIRST site), and then reference the rule on entaglement (I'll edit this post and give a specific rule so you don't have to hunt, but I've got somewhere to be at 10:00 (and it's 9:58
)), you will find that it considers any space larger than 4in^2 to be a hazard. An uncovered robot would most certaintly then be considered a hazard. |

Re: covering...
Ours is covered on front and back with heavy duty laminated paper and lexan respectively. The sides are protected by lexan. There's no covering over the top because the front covering is slanted and will also deflect anything coming from the top.
The electronics this year got the most covering out of the other years I've been on the team as far as I know. I just dread that thought of something punching through the RC during a match, still keeps me up at night. Last edited by Shu Song : 01-03-2005 at 22:30. Reason: lots of typos |

Re: covering...
We got so tired of the same ol' box shape we've been using for the fast 3 years, we decided to try and keep our frame to one level. We have lexan protecting our electronics and placed a "push bar" in the front, but we left our wheels, compressor and air tanks pretty much exposed. I'm a little nervous, we'll see in a few days at Sac Regional.

Please remember that inspectors and IFI personnel need to be able to see the RC while the robot is powered. As a reminder to all, entanglement issues are investigated to make sure "YOU" can continue to play. If another robot should get entangled in hoses and wires on your robot, you will likely receive more damage and may stop altogether. Please also note that the team compliance statement on the inspection form has a place for the Team Inspector as well as captain and mentor. Last edited by Al Skierkiewicz : 21-03-2005 at 13:46. |

Re: Covering your electronics
Why do we cover our robot with lexan?
A few dollars of lexan protect expensive equipment/electronics. Money = Something we do not want to spend on something that could have been prevented from damage. Also a place for team number, sponsers, and our TIGER EYES! |

Re: Covering your electronics
we had are RC and breaker panel seprate from the rest of the electronics (space). We covered the places for the panels on all sides (and made sure not to get out of the box). The other electronics were almost hidden, but vulerable enough so we covered that too with lexan. Becuase of the location (CIMs, 7 victors, FPs all in a small pocket), we also put one of those big fans to keep it cool. Another reason that armor could be bad, but I would still use it.
Every year, we have armored. And there has been more and more armor each time (umbrella, slight cover, metal cover, full sheld, full sheld with metal bars surrounding). Nothing very dangerous has happened. But last year, we flipped and our armor came off when the battery flew out, which could have broken something. So we put it under the arm this year. The only way it could go anywhere is out the frount (small gap), where there is nothing. |

Re: Covering your electronics
Ours is semi-covered. It's protected by the chassis but if something gets under the robot we're screwed. I wanted to add lexan around it but wasn't allowed... i'm definitely putting some on at UCF though, don't want anything breaking... *shudder*

Re: Covering your electronics
All of our electronics is mounted in the center portions of our robot, on the bottom base. Alot of our wires are run under the robot, zip tied up in the angle iron that forms part of our frame. It is protected from the side by the frame, on the back we have some carbon fiber on a vertical piece of the frame. On the top we covered the entire top of the robot with clear lexan. The only place we are vulnerable as far as accidental ripping out of electronics is from the front, but even that is covered with a small amount of lexan. Picture here .

Re: Covering your electronics
The bottom of our bot is sectioned in lexan and mounted to the frame. We also have (I'm not sure of the gage but i think its 24) sheet metal sides to protect the drive train and lexan front and back to see speed controllers and control panel. Then on top a cover to make sure no bot accidentally hooks our guts.
Remember you need to have easy access to your main breaker. First rules say that there should be no obstruction to the breaker. Last edited by Babyhueyhnx : 02-03-2005 at 23:19. |

Re: Covering your electronics
you should always cover your electronics because the people who wired the system put a lot of time and effort in to it and they dont want to make any major changes to the wiring. So protect it please.

Re: Covering your electronics
this year for team 1368 i made all of the eltronics in a box that was made out of 1/4 lexan it weighd 13.5 pounds and i could be taken out in less then 5 mins. it whent in the front of the robot i posted a pic of it a while ago.
i felt the need this year to do that because last years eltronics was a rats nets. and i felt it would look great whitch i got a lot of complements at the fl regoinal at ucf. also are arm would come right down on top of it ben 1368 Last edited by savage : 21-03-2005 at 13:23. |

Re: Covering your electronics
After having been Lead Inspector at Boilermaker over the weekend, I do need to remind everyone of a few things electrical. You must use the SLU70 compression connectors provided in the kit. These must be on all #6 (or larger) wires attached to batteries, 120 amp circuit breaker and breaker panel input. And please remember that all connectors and battery terminals need to insulated. Should a tool fall on the unprotected terminals of a battery, the tool may weld itself in place causing a permanent dead short. All batteries must be the EX18 or ES18 stated in the robot manual and inspection checklist and can be charged with the six amp chargers specified. Inspectors and IFI people need to be able to see the RC, OI, speed controllers and Spikes to help you when problems arise. You must have version 10 firmware loaded in the RC. This is available on the IFI website with the instructions and loader software.
Don't forget you need a student for team inspector and team captain as well as a mentor to sign the compliance statement on the inspection checklists. See you during inspections at the Midwest Regional on Thursday. Last edited by Al Skierkiewicz : 21-03-2005 at 13:58. |

Re: Covering your electronics
As field manager for two regionals, I have a couple of observations:
1. Protect the Electronics 2. Cover the unused I/O Pins on the RC especially when you are working on the bot. Between GLR and Detroit we saw at least 10 cases of contamination causing comm or control problems on otherwise functional bots. After the pins were cleaned, operation returned to normal. 3. The Field manager, refs and IFI reps all want to help have technically flawless competitions, therefore make the RC, spikes etc visible as we check before the start of each match. 4. Accessibility, battery lugs will loosen, you will occasionally need to reset the RC, etc. Make the electronics as accessible as possible. Good Luck, Ben Tower |

Re: Covering your electronics
Wait, pleeaase don't tell me some teams don't protect their electronics. I beg you, have mercy on your robot's brain.
