You mean like fitting an LED? :)
I tried to tell the same thing many times before. The LED is a confirmation that the system is active, therefore more dangerous. It is a visual aid to ensure that people are aware that the link is in. That the system is live.
Mind you, a LED burning when the link is not in is a serious problem as well. And a LED not burning when the link is in is a serious problem too. You should not trust it to tell you that the robot is safe or unsafe, it is only a visual aid to remember something you should know but might have forgotten in the exitement. And it is a visual aid for those who dont know your robot and have to be near it for some reason.
Personally, I have found having lights on a robot helps diagnose problems you might experience in the arena. I had a pair of flashing blue beacons on the top of ToeCutter2 (and the animated pig of course!). They also helped as a reminder to turn the remote fail safe on/off as required, and gave an aid to the state of the electrics in the robot. The pig also helped, as it was in the failsafe circuit too, with visable movement and audible sound, though on a seperate circuit, so if the lights failed/got damaged etc, I still had an additional indicator. Seemed to work quite well all in all.

Hmmm, colourblindness... Im colourblind and have hell with the red and green LEDs on my SLA charger.
Maybe one day Ill label them :sad:
ok, with the hostile response that the on topic LED suggestion got, can we go back to airyplanes now please :)
Solution to the colourblindness thing - have a group of women to check the LEDs through some sort of binoculars - correct me if Im wrong, but my high school biology teacher told us that women cant be colourblind.
(Or have haemophilia, incidentally)
-- Kev
They can, but it is unusual (because of a genetic redundancy).
I have a better idea for spotting red/green (unless you want women to watch you with binoculars:proud:)...get some red and green pieces of glass...use as filters...
or pick a colour you can see? as it was you who picked the LED and its you that has the problem?
Women can have heamophilia, but the effects are normally less severe.
Ahh yet another joy of being male.........
But hey - being able to reverse park makes up for all that :proud:
Excuuuuuse mee!
Women can reverse park, or at least I can most of the time :)
James, you got what you wanted, its another off-topic discussion! I wonder how long itll take before Fluppet finds his way here?
Here: http://annuaire.pepere.free.fr/aventures/pepere.phphttp://annuaire.pepere.free.fr/aventures/pepere.php
So you can both practice.
If this topic carries on in this manner it will be locked.
Keep it on topic.
lock the topic sooner the better.
The only thing that suprises me about this thread is not the fact it has gone off topic, but how the hell can there be the better part of 300 posts on a subject as simple as an LED that comes on when you plug in your removeable link??!!
Chris & Kane,
Sorry guys, we have something on this forum called freedom of speech. OK, this paticular thread may be a bit off topic, but providing there is nothing on it that is ilegal, offensive or brings the community and/or the FRA into disrepute... it will not be locked or any indvidual posts deleated.

Freedom of speech?
With all due respect Geoff Id have to disagree on that one.. theres no freedom of speech on here any longer.
Some people have decided covering their own *ss is to important!
Sam
how many threads over the yrs have not gone of topic
exactly Lee, wonder how long this will get before it ends
This is the thread that never ends,
It just goes on and..........
what do poeple think of salad from mcdonalds.
Sorry, I forgot to add of no value to the community to the reasons that may be used to edit a thread. So think before posting anything too silly!
Geoff.
Fine!
Guess Ill have to stop watching the Safety dicussions to reduce the volume of SPAM I get.
Chris - Salad is for wimps
I agree Steve.
and it is soggy
What do you mean Lee u have actually tried it :)
Christian: About this long. :-)
Kane: You have my sympathy regarding post topicality, although in this case I think the topic was done to death before it went off at a tangent - anyone reading the first few posts will get all they need to know and more. Nonetheless, if something starts a discussion, I have to agree we should keep it. Sorry this means you get junk.
To go vaguely back on topic, other than the limits on type of laser, are their any upper bounds on light being emitted by a robot? Should there be a bound on whats too dim to be visible, and whats bright enough to be nondistracting? Just wondering about making a light show out of the feature. Optical illusions (how fast *is* that disk spinning?) and all that.
Sorry if this is covered in the rules anyway, but at least its a change from colour-blindness.

In fact, my initial very first post was NOT only concerning the power LED, but also about the failsafe LED. That was the one i had problems with.

once years ago i have learnt better since then but think Stu still as it :)
I€™ve skimmed through the 300 odd posts so please forgive me if a full and workable answer has been given, (in this thread or another), but the way this thread has gone off topic, please bare with me.
LED to show robot is powered. I think is good idea, easy to fit and has been covered. This is NOT what I€™m asking about.
It€™s the Failsafe LED. Rule 4.3
Quote; Feb 2 2004 from Sam, FRA safety executive.
€œThe failsafe light is due for a rewrite in the rules and is being moved to advisory status both because of technical difficulties in fitting for some and for the reasons of confusion that many of you have discussed above, it is currently not being enforced by any FRA events.€Â
The New rules are out and from what I can see this has NOT been moved to advisory.
I€™ve got my Power/Link LED, but wasn€™t going to bother with the failsafe LED, if it was to stay advisory only, mainly due to the fact I€™m not sure how I would go about fitting it!
Should it still have been moved to advisory but was over looked in the rewrite, or has it now become fully required?
Guy.
Don€™t tell me I€™ve killed this long running thread by going back on topic!!! ;-)
Anyway€¦€¦€¦
Been thinking of a simple way to show a robot is in failsafe mode - which I take to mean lose of signal.
If you have a spare channel on you RX you could plug in a FS1 failsafe unit connected to a servo which operates a micro switch. This micro switch operates a LED.
Normal operation - the micro switch is open, leaving the LED Off.
Lose of Signal - the FS1 activates (along with all other failsafes in robot), moving to its failsafe position, which closes the micro switch, leaving the LED On. There by showing failsafes are active.
You may also be able to incorporate the €˜remote kill€™ into this set up.
In my opinion, that does not seem so good.
I wrote (before the thread went off topic) an far simpler idea, with a similar effect. (With the exeption that interference will make it blink)
Still, this shows that the LED-controlling FS1 is in failsafe mode. But there could be a lot of reasons for that, i.e. the connection to the reciever is broken. What you want is a LED showing that the failsafe device that actually controls the motors is in failsafe mode.
Jonas,
Had alook but couldnt see you original post. What was your idea?
Guy
Placing a LED directly on the output of the reciever. I know that its not very good, because of the reasons above....

So do my robots eyes lighting up when the safety link is inserted count? 14 ultrabright blue LEDs

Hello is there anyone from the FRA out there?:)
Since Guys above post got no official response Ill ask it again. Do we need the light to indicate when the robot is in failsafe mode. Given the cofusion and contraversy this rule generated I understood it was to be dropped.

Link goes in - light comes on.
Link goes out - light goes out.
If YOU wish, you can have other lights to help show if your bot is on remote kill or in failsafe mode or if a weapon is active - BUT all lights must go out when the link is pulled out to show the bot is dead and theres no way it can move.
This LED/Power Light rule is for all weight classs. (Apart from AntWeights and below).
