Rule check

Hi there,

just reading through the rules at http://www.fightingrobots.co.uk/documents/buildrules2007.pdfhttp://www.fightingrobots.co.uk/docu...drules2007.pdf and I thought Is ask for some clarification, Ill ask them one at a time here...

Quote:
1.5.4.
All Robots not in an arena or official testing area should be raised on their carrying cradles in a manner so that their motive power cannot cause movement if the Robot were turned on, or cannot roll or fall off a pit table. Runaway Robots are VERY dangerous.

So I dont have a carrying cradle, would putting the robot up on blocks be acceptable?

Thanks - Simon

In the past we have seen a lot of things to hold a robots wheels of the table/floor.
Ranging from a hard plastic toolbox to a complete moving workbench, including loading crane. From a nice welded trolly to a couple of bricks.
But the event organisers are asking for better constructed cradles.
So , we have a H made of 4 by 4 wooden beams.

Simon, just make a frame from some strips of wood, making a cross or an H shape, and place the feather on that so it is stable and the wheels move freely without touching the table. It shouldnt take more than a couple of minutes to make.

OK, thanks very much.

Now question 2.

4.1.
All Featherweight, Lightweight, Middleweight, Heavyweight and Super heavyweight Robots MUST use VHF frequency band 40MHz. (with the exception of UHF frequency 459 see 4.1.2) Antweight robots are permitted to use the VHF frequency band 27Mhz.
4.1.2.
The UHF frequency band 459 may be used - but inform the event organisers at the earliest opportunity.

So I take it that 2.4GHz is also allowed?

Thanks - Simon

In theory, it isnt.
But nobody will complain when you use the 2.4GHz.

Simon,
2.4GHz was approved for use in all weight classes as of November last year following DTI approval. We have just been a bit slow about adding it to the rules document..Sorry.

Thanks again guys.

OK, slowly moving along, the next question is about

4.2.
On Featherweight, Lightweight, Middleweight, Heavyweight and Super heavyweight Robots, all operating circuits that are deemed to be dangerous (normally the drive and weapons) must have a failsafe device fitted to each circuit.
This MUST bring that circuit to a pre-set off or zero position if the transmitter signal is lost. The robot should also failsafe if the receiver should lose power, to prevent further operation.

Would a Spektrum BR6000 count as a failsafe device fitted to each circuit, it seems to failsafe the drive motors on my antweight robot?

Thanks - Simon

It does, the Bot Reciever 6000 is specificaly programmed to do so.

And the FRA rules dont care what failsafe mechanisme you use, as long it works.

Simon

The BR6000 will failsafe on all channels, the AR6000 will not.

I have also heard that the Futaba 2.4ghz system will only failsafe on one channel only, perhaps someone out there can confirm or deny this?

Confirmed, by Robbe to me directly via Email.
