Talk to the FRA

Why does the forum keep going down?

We had a corupted table in the database after a reboot. Previous issue was due to unscheduled maintenance and won't happen again how much time do you spend on here

whenever i came on during like 4 days it was down so i was just wondering

getting bored again of the forum so prob gonna hide for another few months come back and see how boring it still is like iv just done lol

but when i bought my dx6 all that stopped

One comment that has stuck in my mind from the 'Safety issues' thread in the Safety Discussion section was along the lines of 'switching to 2.4GHz doesn't solve the problems and eliminate the interference, it merely masks it'
So all that interference is still there, it's just that the radio system 'overpowers' it

There can only be interference if the workings of a robot are disrupted. If people don't have an issue of disruption on 2.4GHz, the interference is eliminated. QED

Moving everything to 2.4GHz does create a more stable platform were the emphasis is on fighting and driving, not hoping your robot will run. That is an added bonus for the roboteers and Event Organizers alike. We (DRG and GRA) wil still allow for 40MHz to run but will also advise people to migrate to 2.4GHz whenever they can.

When are the minutes for the last GB meeting going to be published?

[Scorpionbuilder]

The minutes have been approved so they should be up within the next week

Many thanks

Not a question to the FRA as such, more to the forum moderators, but if I want to post details for a robot event thats not FRA sanctioned (IE: an Antweight World Series), do I have to send the details via you (the moderators) to go into the Live Events section ? I posted the details in live event discussion this time, but just for future.

Only FRA approved event organisers can post in the Live Events section of the website. Please send me an email.

Hi All

Having been asked a specific question by a roboteer regarding the building of a walker, I had to go back to the build rules. All the build rules tell us are:

2.2 Legged robots (Walkers) can weigh up to twice the specified weight in all classes. A walker must employ moveable legs to support its weight. Robots with rolling or sliding mechanisms will not be classified as walkers.

This to me seems very vague so I thought I'd ask all of you the question:

What do consider the true definition of a walker?

I look forward to your thoughts

John

The difference is in the action of the foot or lower leg of the robot.
If you trace the movement is it mostly linear or circular in profile?
To give examples the Lego model has a crank to operate the leg. but the foot motion is a flattened ellipse not a circle,
but the second one Son of Whyachi the feet are in effect fitted directly to a crank.

I don't really know what I would consider to be the definition of a true walker, but I've always classed Anarchy as a walker in my mind. Even when the rules were changed so that it was classed as a shuffler, I never thought of it as that. The problem with that I guess, is that people will find ways to replicate Anarchy's leg mechanisms without using much weight and will then be able to fit much heavier weapons systems on to their double-the-weight-limit robots which in turn may prompt other people to complain about the classification of a walker.

But then this is just my opinion. I think it's difficult to fully classify as well. For example, I consider Clawed Hopper to NOT be a walker, but I believe that is similar to the mechanism used in DrillZilla (except more precise and much faster) which I originally DID class as a walker. So a lot of it could come down to personal opinion.

The best example of a walker that I can think of is Junior, built by the Plunderbird boys for Technogames. A lovely little machine to watch in action, and that is something I would definitely consider a walker.

Sorry, I know that's probably not much help :P
