AKA... me.
Ive got magnets in my new featherweight as seen here;
http://www.youtube.com/watch?v=coeZuPhgXec
rules of safety regarding droping the robot on your feet etc? .... Come on your not that stupid? If you drop any featherweight on your foot etc its gonna hurt....
And should we ban all magnets? like the ones in your drive motors?
Theres nothing in the rules saying magnets carnt be used... and im not the first person to of done it.... i dont break the rules i bend them :)
Also - its easy to weigh 540- just balance it on the scales so the magnets not facing down... the magnetic field isnt that large, and it deffinetly wont effect anyones radio signal.. my RX is mounted 40mm away from the magnet... and its litrally touching my sidewinder.
And yeah- suppose 360 could be classed as a hover bot.... but not intentionaly... so who cares....audience love it.
Come on guys stop rule bashing.... if theres nothing saying you carnt do it... think outside the box and give it ago.. instead of trying to stop other people making things more interesting.
what strength magents do you use (mind me asking)? but they are obviously strong :)Quote:

1mm base then 5mm ground clearance gives around 38kg of pull, plus the 12kg of robot and it works out to be around 50kg total robot downforce in weight.... not mass.
No, because that machine would still weigh 30lbs. Stick it on a set of scales with plastic surfaces (negating any magnetic pull, just for clarity) and it would still show 13.6kg. Okay so it would be harder to pull/lift up from the arena floor but that doesn't mean it weighs more (in terms of mass, rather than actual W=mg weight)Quote:
surely that machine would breach the 30 pound weight limit as stipulated in the rules
I agree with the comments that using magnets is simply making use of the arena environment (steel floor) in the same way as a ground-skimming wedge makes use of the arena environment (flat floor). If something is compromising the enjoyment or competitiveness of the sport, then by all means alter the arena environment to hinder it*
But I sincerely hope the rules aren't re-written to banish magnets; too often in this spobby rules have been re-written because someone has exploited a loop-hole (perhaps abroad more so than here), usually in ingenious ways. But rather than applaud and admire their ingenuity, the loop-hole is closed because there were murmers of unfair advantage.
*For example, the discussions about having an uneven surface to discourage wedges. However steel floors are still relatively new and presently only feature at Robo Challenge events, so not only has the utilisation of magnets been impossible until recently, but they can only be used at one or two events per year.
I don't think you're breaking the rules or even bending them. It's within the rules and no-one else is prevented from using them. Safety rules in terms of stregnth of magnets?? ...............don't put two magnets together with your finger in between..........anything else? it's a sport where we abuse lipos which can be very nasty if abused and we use 65bar pneumatics etc etc so people should have some idea of any risks with magnets like...........erm........getting it stuck on your robot (Dave Weston springs to mind :lol:)Quote:

This is what i mean when i talk about dangers. Seen a site a while back where a guy had one sitting on a wooden bench and it jumped a foot sideways crushing his fingers against a metal object at the end of the bench.
Just to reiterate, this was originally a quirky thread looking at the possibilities of putting helium inside a robot.....
I don't wanna start a fight!
Don't worry PJ, no fighting here :)
Just some decent discussion/debate. It's been a bit quiet on the forums lately so we're all just jumping at the chance to stick our teeth into something substantial.
