Power/failsafe LED

Placing a LED directly on the output of the reciever. I know that its not very good, because of the reasons above....

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.

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.€

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).

Do the current rules specify that all lights have to go out when the link is pulled? My robot has quite a few LEDs which show the state of the receiver, signal indication etc which run off seperate batteries. In fact in its last incarnation it had over 300 of them. Do I need to put gaffer tape over them?

Looks like this rule is evolving and cant make its mind up. Suddenly with Stus version, M2 no longer complies. Equally, for a different reason, these lights can stay on for some time due to the capacitance in speedos or be lit by motors generating when the bot is dragged out of the arena. I am not changing it again so it is what it is!

The power light LED, not leds on signal things.
Coz u cant reallt take all leds of all interfaces etc.

Just the main powerlight led.

Is this legal.

I have 3 lights on my hobbyweight.
Red: Link Is In
Yellow/amber: Batteries are pluged in
Green: Rx has power.

Only the red led goes off when the link is pulled does this mean i cant use this set up?

OK, thats it!
Scrap the rule!

It€™s up to ambiguous in the way people interpret it, even though it€™s formulated clearly.
The use of the rule seems doubtful.
Theres nothing wrong with fitting indicator leds to your robot. As long as you yourself are the only one who will interpret them. Interpretation by anybody else seems to be more of a danger than a safety precaution.

I agree Stefan.

Shouldnt you normally indicate by some means where the removable link and possible gas vent is ? Cant we apply this to the main power LED as well ?

Power/failsafe LED

there is a little green led at the back of my bot, that is on when my link is in, and off when my link is out. And if that is not ok with you guys, tough.

Thnx for the info.

Paul, Ill mention it again just to make this thread a little bigger. If the(any) LED is ON then the robot has power. If its off then either the robot is not powered up or the LED is faultly. If after you have taken the link out and the LED is on then you must assume that the robot still has power. Even in ours it takes around 10 seconds for the LED to go out. It is an indication there is power in the robot. Ill say that again just to make sure you all get that. It is an indication that the robot still has power.

If the robot still has power then it is still cabable of moving/activating weapon. If you push the robot along and the LED lights up DONT assume that the robot is safe. It now has power again, maybe even enough to activate your weapon. OK most people who use CO2 will have turned the gas off before they move the robot.

Now if there is another LED that is on after the link is on then how do other people know that your robot powered down. They dont. So dont fit it unless you can turn it off before it leaves the arena.

This rule is here and if you have problems with it then by all means ignore it if you want but dont make a fuss if you get kicked out of an event because of it. If you want it changing then get your local FRA rep to bring it up at the next meeting. I think the rule is clear in what it says and common sense tells us how to implement it. If you are still having problems then I suggest you give up now.

So lets get this straight:

Stu: all lights must go out when the link is pulled out
Stu: The power light LED, not leds on signal things.
Coz u cant reallt take all leds of all interfaces etc.
Mark: Now if there is another LED that is on after the link is on then how do other people know that your robot powered down. They dont. So dont fit it unless you can turn it off before it leaves the arena.


...and the FRA rules available on the website just say you must have a power light, they dont say anything about all lights being off when the link is pulled.

This is ridiculous. Ive heard more lucid games of Mornington Crescent.
